Hello everyone,

I have two old rifa caps in a snubber circuit(I guess). I couldnt find any document about them, please can you advise me modern caps instead of these rifas.

Ice-Tea:
Safety film capacitors. Rated X2 or Y2 depending on whether they are L - N or L/N - EARTH/CHASSIS.
madires:
If no safety caps are required you could use Wima MKP series.

These are not safety caps. Rifa made multiple series of that garbage. They can be replaced with regular polypropylene capacitors. Polyester should be fine too in most cases.
Ice-Tea:
They are most often found on primary side, including filters etc. I stand by my recommendation.
