Substitutes for GSC T18C 1500uF 6.3V caps

[Andre Majorel]

Can someone recommend a subst for this 1500uF 6.3V electrolytic
capacitor:

GSC
[RE] 105°C
T18C

Radial pins, 200 mil pitch (apparently).

This is for a Soltek SL-65KV2 motherboard that just died. Two
caps swelled up and two others actually started leaking
electrolyte.

Thanks in advance.

Can someone recommend a subst for this 1500uF 6.3V electrolytic
capacitor:

I'd probably recommend something like a Panasonic FC or FM series
capacitor - 105-degree-C rated, designed for switching power supply
applications.

GSC
[RE] 105°C
T18C

Radial pins, 200 mil pitch (apparently).

I'd guess that's a 5 mm pitch?

Panasonic FM series has a 6.3 WVDC 1500 uF cap, 10 mm diameter, 20 mm
high, 5 mm lead pitch - their part number is EEU-FM0J152, Digikey
part number P12343-ND, Digi-Key price $0.59 each.

You might want to go up to a EEU-FM0J222L, P12344-ND at $0.61 each -
same diameter, same pitch, same voltage, 2200 uF, 25 mm high.

FC-series equivalents (not quite so good a set of ratings) are
EEU-FC0J152 and EEU-FC0J222.

This is for a Soltek SL-65KV2 motherboard that just died. Two
caps swelled up and two others actually started leaking
electrolyte.

Don't you just love having to suffer the consequences of somebody
else's incompetent industrial espionage?

Eh? If it was incompetent, then I'd think the epsionage would be
unsuccessful. Maybe I'm clueless as to what you're referring to. In
any case, nowadays, it's common for the MoBo to be replaced before any
of the parts die.

Yes, about 5 mm. Can't tell 5 mm from 5.08 mm with a ruler.

Loving every minute of it. And there's more to come since there
are at least a dozen more capacitors of the same manufacturer on
that board.

of the parts die.

Over the past few years, a whole bunch of motherboards, and other
industrial and consumer-electronics devices, have died a premature
death due to capacitor bloating and leakage. The lifetime of the caps
involved seems to have been on the order of 1-3 years, depending on
temperature and load - sometimes as little as six months. This is
seriously annoying for motherboards (not everybody wants to replace
'em after a year or two) and really annoying for network
hubs/switches, 802.11 access points (both of my original-model Apple
Airport base stations quit due to this problem), etc.

The cause was incompetent industrial espionage. As I understand the
story, somebody who had worked for a major capacitor manufacturer (in
Japan) stole the formula for his employer's new capacitor electrolyte
formulation, and sold it to competing manufacturers in Taiwan and
China. The formula "as sold" (and possibly "as stolen") was
incomplete... it didn't include some of the stability additives. Caps
made with the incomplete electrolyte tend to self-destruct - the
electrolyte begins outgassing, the caps swell up and go high-ESR and
sometimes leak.

http://www.spectrum.ieee.org/WEBONLY/resource/feb03/ncap.html has one
version of the story.
