    I have a Soyo motherboard
    <http://www.soyousa.com/products/proddesc.php?id=219> with 7 1500uf 6.3v
    caps crammed against each other. 3 in the middle are apparently
    preparing to explode. These caps are 8mm in diameter. I checked Allied,
    MCM, Jameco, Galco and several other suppliers listed in the FAQ. Those
    few that have 1500uf 6.3v listed only have them in 10mm diameter or
    larger. Where can I get replacements that will fit?

    Felix ! Is the board under warranty because
    a high percentage had bad filter caps.

    Felix Miata:
    Finding the replacement caps is only HALF of the problem. There are
    possibly some other circuitry failures and other faulty components that may
    have caused ALL THREE caps to overheat and fail. If you just replace the
    caps and do not check for the reasons why, they may fail again shortly after
    replacement.

    Info below taken from Abit newsgroup:

    This is a well known problem. There were a lot of bad caps sold a few
    years ago. If you want to fix the board you really need to replace all
    the caps. I'm sure you have more bad ones. There are two right under the
    AGP slot that usually go first, and if you have any that are domed on
    top or are leaking any black or brown substance they are bad also. You
    can go here if you want to get the board repaired.

    Here are just a few of many links about the cap problems.

    Warranty? Surely you jest, according to
    http://www.soyousa.com/products/proddesc.php?id=219, this item had a
    measily 90 day warranty to begin with. It's an AT board, prolly made
    more than two years ago. It's newest available BIOS is May 2000.

    I've read all the stories about bad motherboard caps, except where to
    buy new ones. Apparently 1500uf 6.3v is an uncommmon type in general,
    and even more rare in computer grade.

    Try this Digi-Key part number: P5115-ND

    It is a 1000uf cap and I've used them on numerous MB's to replace
    leaky caps. Made by Panasonic, they're 8mm diameter radial lead caps
    that fit everything I've tried them in. Since they're used for
    filtering, they should work just fine in place of your 1500uf's.

    If you live in the USA, or don't mind international shipments,
    they've got them at http://www.digikey.com ...

    I saw they have them, except that I don't see the words "low ESR" or
    "computer grade" either in that site's description, or in the pdf it
    links to <http://dkc3.digikey.com/PDF/T032/0661.pdf>. Is there some
    other technical jargon in the pdf that would mean the same thing? Is low
    ESR actually necessary?

    Digikey has these caps... just helped a coworker select them for his
    motherboard:

    Digikey part number: P10224-ND

    Superior voltage and ripple current rating... should have a nice long
    life in this application.

    Have you tried Newark InOne (Newark Electronics) I think they have
    more products than DigiKey. Also, I usually have better luck with
    hard-to-finds.

    The fact that they're 105c HF caps? Low ESR rather follows.

    I've never had a problem using the Panasonic caps.

    The part number for the 48 sitting on my keyboard right now is
    P10202-ND. I also have 48 P10203-NDs, but they're short and big around ...
    sigh.

    Looks like they have the same 10mm diameter 1500uf variety as Digi-Key.
    I don't have room for 10's. I ordered 1200's from

  14. Finding the replacement caps is only HALF of the problem. There are
    In the case of the motherboards, just replacing the caps is the fix alone, as
    long as the bust didn't cause other problems.

    Apparently, these motherboards were made using Taiwanese and Chinese caps that
    used a flawed electrolyte formula. This formula would cause hydrogen gas to
    build up inside the capacitor and would cause it to literally burst the can
    open. - Reinhart
     
  15. Thanks for informing about newark in one Travel Blob. Have beens spending
    some time trying to find new caps for my old Soyo Dragon Plus. This site was
    extremely good, easy to find what I needed and they had it in stock.
     
  16. Those of you who've done this before, anything in particular I should think
    about ? Any advice or recommendations highly appreciated.

    Unfortunately motherboardrepair.com has deleted the instruction from his
    site.

    Thanks
