Replacements for old Cap series?

[GRSHOPR]

I am fixing my brother's mobo, and pulled out some blown electrolytic Al caps, but the series that they're from is discontinued. Can anyone recommend some similar replacement caps? Thanks for looking.

-Rubycon 6.3V 2700 uF, MFZ series (model T0528)
-Rubycon 6.3V 220uF, ZA series (model A0532)
-Rubycon 6.3V 470uF, ZA series (model A0537)
-Rubycon 6.3V 220uF, ZA series (model A0538)
-Rubycon 25V 47uF, YXG series (model A0534)
-Elna 16V 100uF, M tolerance

Re: Replacements for old Cap series?

Not without diameters.
.
MFZ and ZA are the 'models' aka 'series.
The other numbers are just the factory and date code.
T0528 means 28th week of 2005 [05].
.
Blown Rubycons suggests a PSU problem or really bad cooling.

It came out of a Dell XPS with liquid cooling, so I don't think it's that. It looks like (and I may be off on the proper name for the component, it's been awhile) a small step down transformer went ka-boom, and the caps in line suffered. The PCB looks a little burned, but the paths are all just fine, and overall, it looks alright. My brother already tried replacing the PSU, just in case, so, when this gets fixed, that should also fix that issue if it was the cause.

I'll see if I can find diameters, but I don't think dell was in the habit of posting their OEM mobo schematics...

ZA = > YXJ, YXG, ZL , ZLJ (from: http://www.rubycon.co.jp/en/products...ace/index.html )

YXG is not discontinued.

MFZ is probably a custom series... can't help you there. Doesn't show in the discontinued list or I'm blind.

Re: Replacements for old Cap series?

Here is what Rubycon said.


The MFZ series was designed for a specific OEM because of this I have no
data to cross.

The ZA series was replaced with the ZLJ series and the YXG series is
currently available.

MFZ - No replacment

Rubycon 6.3V 220uF, ZA series (model A0532) - 6.3ZLJ220M5x11
Rubycon 6.3V 470uF, ZA series (model A0537) - 6.3ZLJ470M6.3x11
Rubycon 6.3V 220uF, ZA series (model A0538) - Duplicate 6.3ZLJ220M5x11
Rubycon 25V 47uF, YXG series (model A0534) - 25YXG47MEFC5x11

Can't find the 470 uF ZA cap replacement anywhere. Recommendations for a replacement for that one?

Thanks for all the help so far guys.

Re: Replacements for old Cap series?

No one publishes motherboard schematics.
Don't want their competitors to get their hands on them.
.
Most XPS aren't known for exceptional cooling.
.
Water cooling makes CPUs happy, not caps.
In fact it probably reduces air flow to the caps more often than not.
Granted it depends on the setup.
.
Check the MOSFETs closely and make sure none look pitted, cracked or melted.
.
Intel designs most Dell boards and then they are manufactured by Intel or Foxconn.
[Obviously Intel doesn't do their AMD boards....LOL..]
.
MFZ is a custom ordered cap so there won't be a data sheet.
By where they are found they are a good grade so:
I would use Nichicon HN for those unless there are none that will fit.
.
ZA [data sheet attached] is best replaced by HM, WG or similar although in some sizes FR or FM might be good enough.
.
YXG are close/equivalent to HE and KY.
[Depends on can size.]
.
Can't say for sure on the Elna without a series name.
But: a 100uF 16v usually only needs to be like an FC or PW.

Yeah, Rubycon says you can replace MCZ with ZLJ ro ZLH [or something] too and that's a load of crap.
They aren't even close..........
.
Is ~always~ better to check specs yourself.
.
And there is this:
Rubycon from reputable dealers - hard to find.
Nichicon, Chemicon & Panasonic from reputable dealers - easy to find.
.
ebay is literally flooded with counterfeits.

You sir, are a scholar and a gentleman. I will generate a list of components, then throw them up here for approval. Thanks again. The kid is having withdrawal from Star Wars ToR. Haha

Re: Replacements for old Cap series?

As for the Rubycon MFZ ... if someone wants to actually check their ESR (for future reference what to replace them with or something), you can grab them from the PCMC Store. From what I know, they were mainly found in early XBOX360's..
(so OEM only .. no Idea how that guy got hold of them..)

Re: Replacements for old Cap series?

Rubycon MFZ should be equivalent to Nichicon HZ or Samxon GA.

The datasheet exists, probably typed out roughly, as are many datasheets for experimental series.

If you ever find that one send me a copy.
I asked Rubycon directly but they wouldn't cough one up.

Re: Replacements for old Cap series?

FYI: 2700uF 6.3v MFZ has ESR of at most 7mOhm. That's better than MCZ and the same as Nichicon HZ.

Re: Replacements for old Cap series?

Sorry about the delay in response. Had a whole bunch of exams happen within a few days. OK, here's what I'm thinking for the replacements. Let me know if you guys approve. Thanks.

MFZ: http://www.ebay.com/itm/10p-Rubycon-...#ht_1134wt_951

6.3V, 470 uF: http://www.mouser.com/ProductDetail/...FF%252baz7U%3d

Re: Replacements for old Cap series?

Nope...
You want the same or more Ripple and the same or less ESR.
The ZA are extra hard to find replacements for...


Rubycon 6.3V 2700uF, MFZ 10mm, ??Ripple?? / ??ESR??
~seller not trusted~
Try
Nichicon 6.3v 2700uF , HZ 10mm, 3770 / 0.007
http://www.mouser.com/ProductDetail/...mZ8C%252bg8%3d


Rubycon 6.3V 220uF, ZA 6.3mm, 670 / 0.077
Nichicon 6.3v 220uF , PJ 6.3mm,, 285 / 0.480 <<-- no ~ has less ripple and more ESR
Try
Nichicon 10v 220uF , NE 6.3mm, 2500 / 0.030
http://www.mouser.com/ProductDetail/...baZ1qGzbXkU%3d


Rubycon 6.3V 470uF, ZA 8mm, 1000 / 0.043
Nichicon 6.3V 470uF, HV 8mm,, 550 / 0.100 <<-- no ~ has less ripple and more ESR
~ has less ripple and more ESR
Nichicon 10v , 470uF, HM 8mm, 1100 / 0.030
http://www.mouser.com/ProductDetail/...wj%252btcrw%3d



Rubycon 25V 47uF, YXG , 210 / 0.580
Nichicon 25v 47uF , HE ,, , 210 / 0.580 -- okay

Elna 100uF
PW -- okay
.

Re: Replacements for old Cap series?

It would be good to learn the relative characteristics of the parts you're dealing with. Nichicon series like PS (PR), PM (PL) and PJ (= UCC LXV series) were low Z when they were new, but for the PM (PL) series, that was some 25 years ago. I don't think you should go any worse than the Nichicon PW series (= UCC LXZ series), and maybe not even worse than Nichicon's PA or HE series (~ UCC KZE or Rubycon ZL).

FYI:
The ZA series has much much lower ESR than all of the above.
ZA is even lower than Panny FM.
See data sheet posted earlier.

You can see how the more common 'good caps' relative characteristics match up here.

Thanks PCB, I really appreciate your help. I ordered the ones you recommended.
