msi-6309 what caps can i used instead of 2700?

[Pud]

hi all,

the caps on the board are 2700 6.3v and i need to change a total of 4 out of 4. i'm having difficulty getting hold of this type here in australia so i was wondering what other ones i can use? can i use 3300 6.3v instead? any others?
thanks

Try Farnell.

Try Waifong

It seems the most common value is 2200uF . If you use the MCZ series at 2200uF you will be fine they are a top device.

You need to watch the diameter to make sure of a fit, again MCZ will be no problem at 10mm.

Just checked Waifong shipping charge to Australia . It is high for 4 devices, HK$ 888.00 Phew!

Visit Jaycar.com.au. They have Samxon 2200uF 10V but diameter might be problem. Samxon are good quality low ESR.

Seems like Farnell might be the best bet with Panasonic FC.

great thanks davmax. btw hello from perth wa
i have a local repair agent who can get hold of the caps for me except he doesn't have the 2700's in stock and says they are a bit hard to come by.
i noticed farnell have 2700s and jaycar have caps as well.
if i had more time i'd order some 2700s but you're saying i can use 2200s in their place? what about 3300s? i was told that i need to use exactly the same rated microfarid capacitor. is this true?
cheers bro

i use 3300's
rather have overkill than not enough to do the job

Re: msi-6309 what caps can i used instead of 2700?

1. I have recently been researching the effect of bulk capacitance and ESR. IF you replace with ultra low ESR 2200uF you will have no problem i.e MCZ from Rubicon. The drop in capacitance will not be significant. 3300uF 6.3V is hard to get. But I am getting some Samxon GC from Big Pope in Hong Kong.

2. I have contacted waifong (Hong Kong) and their auto freight calculator was in error. You cannot go wrong with MCZ. Suggest you contact them.

3. The FC caps from Farnell have ESR value too high for VRM. The Samxon from Jaycar may have the same problem, a check would need to be made to see if they are GC series (equivalent to MCZ in ESR value).

4. You will need to check the quality of caps from local repair person.

This may give a few options.

Take a look at Topcat's example of replacing 2700 with 2200.

https://www.badcaps.net/forum/showthread.php?t=123

It is absolutely important that the 2200uF are ultra low ESR.

It is my experience and Topcat's that if you are replacing four caps that are obvious that you should also replace other known bad cap brands on the board at the same time. Also check the power supply caps. Then order the lot at the same time. It will cost less. My first motherboard was done piecemeal an it is not a good idea. What caps are on the board? All caps over 1000uF should be replaced, some say over 470uF. Check on cap manufacturer/s.

i managed to order panasonic aluminium electrolytic, low impedance, radial, wire ended 6.3V 2700uF (Miniature Low Impedance FC Series 105°C) RS Stock No. 315-0265 (took that from the website)

and the same again in 1000uf. RS Stock No. 315-0243 to replace the bulging 1000uf (i just noticed all 9 of them bulging).

willawake recommended them in this post https://www.badcaps.net/forum/showthread.php?t=729
so i managed to get them from rs australia in osbourne park.

thanks a lot for your help Dav and kc8adu

It is good to discover FC are available from RS. I have not previously found them through the tree search.

If these are not stock items I suggest you cancel the 2700u FC, their ESR is a little high for VRM at 35 mohm. It so happens that I had some caps arrive from Hong Kong today and I can let you have 3300uF 6.3 Rubicon caps with 12mohm ESR. Cost to me was $2.68 each incl freight.

The offer is at the same price if you need.

Re: msi-6309 what caps can i used instead of 2700?

A further trap is that these 2700uF 6.3V FC caps from RS are 16MM diameter and 43mohm ERS ( the part number ends with S). You would be better served with the 10mm Rubicons I am offering.

Emails have been sent to you to hopefully turn around that purchase.

Re: msi-6309 what caps can i used instead of 2700?

Thank you guys for all your advice and help. I have been reading up on Bad caps for a few days now and I followed your advice and replaced the 5 bad caps on my MS 6309 v 2 mainboard. Everything is OK now.. The old mainboard worked well in DOS but when I wanted to install XP Home, it had Stop Errors, and IRQ_NOT_LESS_OR_EQUAL errors..

In case anyone needs to know what I used, here are some details.

The original 5 caps near the CPU were:- Chhsi WG (M) -40 +105oC 2700uf, 6.3v (10mm x 25mm)

I replaced them with:- Panasonic 2200uf, 6.3v (10mm x 25mm)

I purchased them from:- RS Electrical Components in Sydney:- www.rsaustralia.com

They listed them as:-

Miniature Low Impedance FC Series 105°C
Description:- Capacitor, electrolytic, aluminium, low impedance, radial, wire ended, 6.3V, 2200uF

RS Stock No. 449-0867
Manufacturer PANASONIC
Part No. EEUFC0J222

Total cost inc GST:- $8.64 (I pickup them up from their Smithfield store)

Plus they gave me a copy of their April 2006 - March 2007 Catalogue on CD (for free) as well... They have a book type but that is only giving to business customers as it costs $60.00...

I hope this helps...
