Kemet bought out Rifa and the parts from Kemet with the same P/N also use
a paper insulator. Rifa used to tout the paper insulator as a selling
point, but after seeing so many fail, I won't touch them, new manufacture
or not.
I'm using Epcos brand polyester film safety capacitors as replacements. So
far I've been able to match them up 1:1 with the correct physical sizes
(lead spacing) and values.
All I could find were new similar Kemet
capacitors. Do you know if
newer Kemet suffer from the same problem and I will regret buying them?
I usually replace the Rifa capacitors with equivalent polyester safety
caps (X or Y rated). Kemets are most common and work just fine. It's
not a bad idea, if you're in a 240AC mains country to bump the AC
voltage rating up a bit. I've seen too many line filters with 250VAC
rated caps labeled for either 120 or 240V use. That would make me
nervous if I lived in a 240V country.
