Default Cap availability problems

I'm hard at work recapping some faulty ATX PSUs.

I'm rapidly depleting my stocks of PSU appropriate capacitors. I would like to use UCC KY series but can't find 2200uf in 10mm can diameter. Mostly I am replacing bulged TEAPO SE(Green) and TEAPO SEK (Brown) 2200uf 10v 10mmx20mm.

I have a few Rubycon ZL and Rubycon YXG in this size but these need reforming.

I had to use 3 UCC KMG caps, they seem to work fine, but not exactly sure. Some of the Data Sheets do not give detailed ripple current and ESR data for comparison.

Any used caps that I have I will be reforming as per momaka's excellent thread here:

https://www.badcaps.net/forum/showthread.php?t=50530

I've been measuring capacitance and ESR of my used caps. All the TEAPOs and GLuxon and SACON were garbage. Surprising to me was that every JACKCON cap I tested was extremely close to the rated cap value and the ESR values were no worse than the major brands. I removed these from old ABIT Socket 462 boards! Go figure.

Anyone have any suggestions for sources and/or substitutions for the PSU capacitors?

Thanks for this. I found them on Mouser.ca and also UCC KY series.

Why don't you put 3300/6,3 in there? I don't even trouble myself by stocking 2200 uF, it's worthless.

Rubycon YXJ and ZLH series are also available in that size.

I like the YXJ for entry-level low-ESR, like replacing those Teapo SEK caps. Such entry-level low-ESR caps are usually employed in PSUs with older half-bridge design.

On the other hand, ZLH is quite low-ESR - about on par with Panny FR/FM and FS and better than UCC KZE (i.e. closer to KZH). These I use for 3.3V rails with mag-amp circuits and 5VSB. If the PSU uses a newer design (i.e. NOT half-bridge), I sometimes use these on the 5V rail too.

Of course there are many other choices too. Here's a (slightly outdated but still relevant) list of low-ESR caps generally suitable for PSU use:

(Missing from that list: Panasonic FS, Nichicon HV, Rubycon YXF, Rubycon ZLQ, Rubycon ZLH... and maybe a few others I can't remember right now.)

That would be the case for general-purpose non-low ESR caps - they'll only give you the cap size and low-frequency (typically 120 Hz) ripple current.

I guess if you have them.
The 2200 uF are cheaper... unless one does like you and buys a ton of the better stuff in bulk.
