Wrong size caps, what can you do?

[SonicSteve]

Hi guys,
I have some boards with 3300uf 6.3v caps on them. All OST and I want to replace them.
Problem though,
They are all 10mm Diameter and very close together in many places.
The ones I can find to order are 12.5mm diameter and I doubt that they will fit in such tight spots.
I've searched 3 distributors and none carry suitable capacitors in the diameter that I need.
It seems that once you go over 2200uf the diameter is almost always 12.5mm or larger.
Does anyone have a solution to this?
I've looked at united chemicom, nichicon, and panasonic. None of the suitable series have the right size.

topcat can get you 3300uf 6.3v 10mm caps. Also, Samxon makes a suitable replacement.

Where is your loaction?

In generall, you can bent or angle them, but this needs some room.

unfortunately that's true. these are the only 10mm 3300uf 6.3v i can find on the datasheet:

i would recommend to use 2700uf 6.3v 10mm caps (god brands) if you can find them to replace those 3300uf-ers.

Re: Wrong size caps, what can you do?

Depending on the motherboard desing, i would not replace 3300uf caps with lower ones. Especially the AMD soket A platfrom, with only 4 3300uf caps are sensitive for that. I have had no luck on a K7s8xe+ with 2700uF Oscon. 4x 3300uF is just not mutch margin to reduce it. The ESR is on those boards very important too. Any negative change will cripple the transient behaivior. I would certainely loock to obtain the correct caps for those boards. I think TC or BigPope are the way to go. Waifong`s MCZ are not bad too, and reliable service.
For those other boards, with unpopulated silkscrean, you can use 2200Uf caps and adding the missing ones.

I just purchased 250 pieces of Rubyicon from Wai Fong. They charged $20 USD for Express Mail shipping, and it hit my doorstep a few days later.

Packing was safe and secure, and all items were received. Web site ordering is painless. Due to shipping costs, USA buyers should make bulk orders to avoid paying high shipping costs for a few items.
