Replaced 60 caps between 4 boards and all are working perfectly -- thank you for your help pcbonez!!!

Re: Chemi-Con KY to replace OST RLS?

Yup.
Sometimes the sizes they choose to make don't make much sense.
Not even sure why they still make both 6.3v and 10v when a 10v will work for both.

Re: Chemi-Con KY to replace OST RLS?

Went with the 10v KZE's.

I know they're compatible, but didn't think to search UP a voltage. I guess I was thinking that since the 6.3's were too big (10mm vs. 8mm), that a bigger voltage wouldn't be any smaller in size.

Re: Chemi-Con KY to replace OST RLS?

I'm probably leaning towards the KY's - it'd be around $65 for qty. 500 at Digikey for these, which seems decent, and also because the only 1000uf/6.3v KZE's that I see there are 10x12.5, unless I'm missing them.

I'd prefer purchase from Digikey if at all possible.

See links above.

No, I didn't check the datasheets. I NEVER do. I just assummed that RLS = HD = ZL = KZE = WX, since those are about the highest ESR series I usually see on motherboards.

Since you need many....
The 10v KZE would be my choice because it's an upgrade and only $0.255 each over 10 pieces.

Re: Chemi-Con KY to replace OST RLS?

It looks like those are all 10x12.5 or bigger? The original here is 8x12.5. Thoughts?

Yes.
Brush up on reading data sheets.
The 10 Volt 8mm 1000uF RLS [should be] 16mm or 20mm long.
Also ZL, KZE, KXM, WX, HD, and NRSG [in other words every series suggested] all have a 1000uF 10v 8x20mm.

If the height is a problem that's another story but it shouldn't be an issue in most cases.

~~~

That said, I falsely assumed c_hegge checked the RLS data sheet before posting.

The 8x16mm 1000uF 10v is only .090 ohms ESR and 818 mA for Ripple.
The 8x20mm 1000uF 10v is only .067 ohms ESR and 1023 mA for Ripple.
[If it's actually 12.5mm long as you said then it's a custom size and the specs will be worse in a smaller can.]
-
KY - 6.3v 8x15mm - .087 ohms ESR and 840 mA for Ripple
KY - 10v 8x20mm - .069 ohms ESR and 1050 mA for Ripple.
-
In this size anyway KY is about as close to an exact match as you can get.
The caps mentioned earlier would be a reasonable upgrade though.

Motherboard from a Gateway E-2610D, ECS motherboard 945GT-GB V:1.1. Just a few are bad around the north/south bridge, but 14 of this same cap on board and will probably replace just the 14 of this particular cap. The rest all look fine and are other make - e.g. Ruby MBZ, etc.

I'm probably going to be doing a LOT of these boards in the near future.

Re: Chemi-Con KY to replace OST RLS?

Is it on a motherboard or a PSU? If it's on a motherboard, these will work just fine.

Re: Chemi-Con KY to replace OST RLS?

I did just notice that I originally said 10v, but these are indeed 1000uf/6.3v. :S

Re: Chemi-Con KY to replace OST RLS?

The ideal replacment for RLS is Chemi-Con KZE, Rubycon ZL or Nichicon HD. KY has a higher ESR.

Btw, KZE is NOT affected by the problem that plagues KZG and KZJ.

Yes, assuming the same can size that is correct.
Also Sanyo/Suncon WX, Illinois Capacitor KXM, and NIC Components NRSG.

Still getting the hang of finding good replacements when the spec sheets don't include all specs.

Would a Chemi-Con KY series be a good replacement for an OST RLS series?

1,000uf 10v.

If not, does anyone have any better recommendations?
