[Amps] TenTec Titan 425 HV filter caps

[rgroh at swbell.net]

I don't think you are overlooking anything - usually going to the equipment manufacturer costs you more because they have additional markups. My only recommendation would be that you use a 105 degC rated capacitor rather than the 85 degC part you listed below. Mouser has CDE parts on pg. 614 - series 381LQ and 381LX, 330 uf, 450 WVDC, cost about $8 and $12 respectively and both are in stock. Both 105 degC parts, and the more expensive one has higher ripple current rating. 

Keeping in mind that higher temperature and higher ripple current ratings are good and that replacing parts is an investment, I would go for the higher quality part. I didn't check the physical sizes (both are snap in). I also didn't check any other alternatives. 

Hope this helps

Hi, all concerned:

These caps are 330uF 450V, 1-3/8" dia X 2" high, 7/16"-spaced leads one end 
(snap-in, I think) for pcb-thru-hole mount.  One blew, thru its top 
stress-reliefs, fortunately spewing no mess.  From their "TSU" markings, I 
believe them to be Panasonics.

I inquired of TenTec about replacement caps: $35 apiece.

Mouser number 5985-380-450V331 and Digi-Key P10167-ND appear to be 
physically and electrically suitable, and are <$10 each.

What am I overlooking, if anything?

TIA & 73, Dave, N3HE
