Can someone check this order list for Samsung 223BW replacement caps please?

[Karpatia]

I've been through the posts and tried to work out what I need.

Here's an image of my board:



These are the specs of the caps on the board:

C107 = 47uf 50v 105°C, 5mm D x 10mm H
C111 = 820uf 25v 105°C, 10mm D x 20mm H
C112 = 820uf 25v 105°C, 10mm D x 20mm H
C113 = 330uf 25v 105°C, 10mm D x 15mm H
C114 = 820uf 25v 105°C, 10mm D x 20mm H
C316 = 820uf 25v 105°C, 10mm D x 20mm H
C317 = 820uf 25v 105°C, 10mm D x 20mm H
C318 = 22uf 50v 105°C, 5mm D x 10mm H

I'm based in Europe, but have used the US Mouser site.

I understand I need high temperature, low ESR caps (are these the same as low impedance?).The sizes are wherever possible the same or perhaps smaller than the originals.

Here's what I found:

C107 = 47uf 50v 105°C, 6.3mm D x 11.2mm H Panasonic EEU-FC1H470 High Temp Electrolytic Capacitor
C318 = 22uf 50v 105°C, 5mm D x 10mm H Panasonic EEU-FR1H220B Low ESR Electrolytic Capacito
C113 = 330uf 25v 105°C, 8mm D x 11mm H Panasonic EEU-FR1E331 Low ESR Electrolytic Capacitor
C111/112/113/316/317 = 820uf 25v 105°C, 10mm D x 20mm H Nichicon UHV1E821MPD Low Impedance Electrolytic Capacitor (IN STOCK)
OR
Panasonic EEU-FR1E821 Low ESR Electrolytic Capacitor (ON ORDER)

In the descriptions, not all of the ones I found said "Low ESR". So I'd like to ask someone more knowledgeable if these are suitable replacements. Many thanks!

Crap brands don't always have crap specs.
-
You didn't give the original caps manufacturer or series so there is no way to know what the original ESR and Ripple specs were.
-
Without knowing the original ESR and Ripple specs you are just guessing what to use.
Since we don't know either we would just be guessing too.

They look like Capxon. The series should be a two or three letter code.

Don't forgot to replace C318 and C107 (the little ones).

Looks like Capxcom GL series.

I should add that since you're in Europe, farnell may be a better choice for you as they ship from UK (if I remember correctly).

Farnell has Rubycon capacitors which imho are just as good as nichicon or others specs wise.

However, farnell Uk has a minimum order value of £20 as normally does RS,PLUS VAT, although the P&P is free...have you no local electronic store, or maybe Maplins is worth a look, although they are certainly not cheap.

I'm afraid I don't know anything about the quality of the brands, so was following PlainBill's advice to go for names like Panasonic and Nichicon. Glad to hear I can spread my net wider and not worry about having to do it again in a couple of years, thanks.

Sorry, when I read all the posts about this monitor, I didn't see anyone mention anything but CapXon capacitors as the originals, so I assumed wrongly that this was the only type used in them and that the CapXon problem was widely known. My mistake.

Yes, the ones that are failing are CapXon. The only other information I can see (on some of the 820's is "C727 VENT". Would that be the series maybe? I can confirm they have "GL" on them (thanks to retiredcaps and Evil Lurker for your perspicacity and the steer there).

If ESR and Ripple specs are important to get the right replacements, could someone point me to a post where I can read up on that? Do I need to look up the ripple current of each of the CapXon's to get the right replacements? What's an acceptable margin of difference in ripple current from the original? Is higher or lower better?

I'm still not sure about the difference between "low ESR" and "low impedance". I think PlainBill was recommending to go for low ESR caps for this and I'm guessing "low impedance" is not the same?

@retiredcaps: Yes, thanks, I put those (C107 and C318) on my list too. Do the replacements look sensible?

@mariushm: Yes, I tried to get into their site last night but it seemed to be down so I gave up. I'll try again today - that should be a lot more convenient if they have them in stock. Those examples are really useful. Mulţumesc!

So if the originals are CapXon GL series C727, are the replacements that I found at Mouser going to be right? Am I looking at the right kind of thing?
- same uF and Voltages
- same size or smaller if possible
- Low ESR (low impedance?)
- NOT 'general purpose'?
- any brand
- 105ºC or higher
- long lifetime hours if indicated

GL is the series. C727 indicates 2007 week 27 -> when the caps were made.

If ESR and Ripple specs are important to get the right replacements, could someone point me to a post where I can read up on that?

PCBONEZ talks about it here

https://www.badcaps.net/forum/showpo...30&postcount=7

I think PlainBill was recommending to go for low ESR caps for this and I'm guessing "low impedance" is not the same?

If looking at the datasheet, then ESR = impedance.

Hi Karpatia
have you taken on board, that there are 10 caps on the board
leave out the big one that leaves 9,
you only mention 8 in your list in opening post

Thanks trebo, yes. There may actually be 11 or even 12 (I don't know if L101 is a capacitor - it's sheathed in black plastic or silicon).



Here's the board labelled more fully:



C105 = Large capacitor that doesn't need replacing?
C107 = 47uf 50v 105°C, 5mm D x 10mm H
C111 = 820uf 25v 105°C, 10mm D x 20mm H
C112 = 820uf 25v 105°C, 10mm D x 20mm H
C113 = 330uf 25v 105°C, 10mm D x 15mm H
C114 = 820uf 25v 105°C, 10mm D x 20mm H
C316 = 820uf 25v 105°C, 10mm D x 20mm H
C317 = 820uf 25v 105°C, 10mm D x 20mm H
C318 = 22uf 50v 105°C, 5mm D x 10mm H
PLUS...
L101 = maybe not a capacitor?
C1... (to right of C107)= uF and Voltage text unreadable
Unknown (to right of C107) = uF and Voltage text unreadable

I read on other posts that I'd probably be safe not changing these other small ones that are obscured by glue.



If I can get them off easily and read the specs, then I will, but I'm a complete amateur and haven't got the steadiest hand in the world, so I want to minimise the damage. :-)

Re: Can someone check this order list for Samsung 223BW replacement caps please?

...lots of useful stuff...

Many thanks rc, that's very useful! Reading PCB's post now and thanks for clarifying the ESR/impedance question.

[retiredcaps]

Re: Can someone check this order list for Samsung 223BW replacement caps please?

There may actually be 11 or even 12 (I don't know if L101 is a capacitor - it's sheathed in black plastic or silicon).

We prefer that images not be inserted inline for a number of reasons.

L is an inductor. C or EC is a capacitor.

C105 = Large capacitor that doesn't need replacing?

The large cap rarely, but not never, fails.

I read on other posts that I'd probably be safe not changing these other small ones that are obscured by glue.

You want to change them all especially if they are Capxon. The little ones play an important part in the SMPS process.

The white glue is put on during factory assembly so the components don't move. You can scrape it off with an exacto knife or something and it will not affect the proper operation of the lcd.

Re: Can someone check this order list for Samsung 223BW replacement caps please?

I looked up the capacitors on the UK Farnell site and found these:

PANASONIC EEUTP1E821 CAPACITOR, RADIAL, 25V, 820UF

PANASONIC EEUFM1E331 CAPACITOR, RADIAL, 25V, 330UF

RUBYCON 50YXM47MEFC6.3X11 CAPACITOR, 47UF, 50V

RUBYCON 50ML22MEFC8X5 CAPACITOR, 22UF, 50V

Do these look right? Thanks.

Try to stick to Panasonic FR, FM, or FC. FR/FM have the lowest ESR and FC is low ESR.

Rubycon also makes good capacitors. Either will work fine.

Noted your preference about the images, thanks.

Took the glue off to reveal that the small one is a 2.2uF 50V. Position is C118.

Image here.

I followed your suggestion and looked for a replacement for that too:

PANASONIC EEUFC1H2R2 CAPACITOR, RADIAL, 50V, 2.2UF
Life Time @ Temperature:1000 hours @ 105°C
Height:11mm
Diameter:5mm
Lead Spacing:2mm
SVHC:No SVHC (20-Jun-2011)
AC Ripple Current:45mA
Impedance:1.8ohm
Lead Diameter:0.5mm
Series:FC

OR maybe this?

NICHICON UPM1H2R2MDD CAPACITOR, 2.2UF, 50V
Life Time @ Temperature:2000 hours @ 105°C
Height:11mm
Diameter:5mm
Lead Spacing:2mm
AC Ripple Current:27mA
Impedance:5.0ohm
Impedance Frequency:100kHz
Impedance Temperature:20°C
Lead Diameter:0.5mm
Ripple Current Frequency:120Hz
Ripple Current Temperature:105°C

The thing behind it is smaller and does not look the same as the capacitors. It's position is labelled IC102. I can't see any text on it. It seems plain black, like a short cylinder with one side sheared off lengthways/vertically.

[Karpatia]

Re: Can someone check this order list for Samsung 223BW replacement caps please?

This is my updated shopping basket. I've changed one of the Panasonics to the series advised by retiredcaps:

PANASONIC EEUFC1H2R2 CAPACITOR, RADIAL, 50V, 2.2UF for C118

PANASONIC EEUFR1E821 CAPACITOR, RADIAL, 25V, 820UF for C316, C317, C111, C112 and C114

PANASONIC EEUFM1E331 CAPACITOR, RADIAL, 25V, 330UF for C 113

RUBYCON 50YXM47MEFC6.3X11 CAPACITOR, 47UF, 50V for C 107

RUBYCON 50ML22MEFC8X5 CAPACITOR, 22UF, 50V for C318

If anyone spots anything amiss please let me know. As I said, please do not assume I have a clue. Thanks :-)

[mariushm]

Re: Can someone check this order list for Samsung 223BW replacement caps please?

The ones you selected look good. I've added some suggestions that are just as good or better than what you picked...see the list below.

The ones in my first post in this thread were already selected to be suitable for your needs.

For example, the Rubycon ZLH has almost the same specs as the Panasonic FR but you don't have to order it from farnell in multiples of 5, like the FR ones. But now that I re-read your list, you need 5 of them anyway so it makes no difference.

http://uk.farnell.com/rubycon/25zlh8...25v/dp/1712580

Sorry to hear there's a minimum order - when I ordered from them a month or so ago there was no minimum value and shipping was only 20 RON (about 6 dollars/5 euro).

Keep in mind also that capacitors rated for higher voltage usually have higher ripple and lower impedance as well.
The ripple imho doesn't matter that much - these circuits shouldn't see 1500-2000mA in their lives - but sometimes you can find capacitors with lower impedance than the current bad ones just by choosing higher voltage ones. They will be a bit higher though, but you have 20-25mm in height there so shouldn't be any problem.

2.2uf suggestions:

http://uk.farnell.com/rubycon/50rx30...50v/dp/8127018 (but it's 8mm wide, 2000 hours @ 130c)

22uf suggestions:

http://uk.farnell.com/rubycon/50zl22...50v/dp/1144712

47uf suggestions:

http://uk.farnell.com/rubycon/50rx30...50v/dp/8127050 (but 8mm wide, 130c )


all above equal or better at specs, at least on paper. They're all much better than the capxon caps so whatever you go with it should be ok.

[Evil Lurker]

Re: Can someone check this order list for Samsung 223BW replacement caps please?

L101 is an inductor... acts as a filter to reduce ripple current. The thing behind the cap covered in white stuff is either a transistor or shunt regulator, or something else in the TO-92 package.

You can tell what most components are by looking at the number code on the PCB. Example, C101 is a capacitor, L101 would be an inductor, D101 would be a diode, Q101 would be a tranistor,mosfet, or other IC, ZD101 would be a zener diode, U101 usually indicates some sort of power IC, Y101 I believe are frequency generation components and R101 would be resistor. The numbers themselves are for locating the components on the PCB, say if were repairing a board and the manual said "check resistor 107" you can easily locate it by its number even if you don't know what it looks like.

It's position is labelled IC102. I can't see any text on it. It seems plain black, like a short cylinder with one side sheared off lengthways/vertically.

That is an integrated circuit.

mariushm knows more about international orders than I.

The only reason I mention Panasonic over Rubycon (though I have used both and like both) is because digikey doesn't carry Rubycon. The badcaps.net store carries Rubycon, but typically not in sizes or voltages for lcd monitors. Like I said, either will work as long as you can find one that physically fits and meets the ripple and ESR requirements.

Re: Can someone check this order list for Samsung 223BW replacement caps please?

Many many thanks for all this Mariushm, retiredcaps and Evil Lurker. That's so helpful. I need to read up a bit more and then recheck the order lists and then hopefully will be able to get it sorted, thanks to your help. I feel I've learned a lot too, which is always good!
