These seem to blow/burst often. I believe the cap is

Correct, althought it's good practice to replace it.

wouldn't replace it with the
exact same type, but with a later cap less prone to blow. Any 250V 220nF cap

than older ones ;-)
should do just fine.
Be very careful here. It has to withstand full mains voltage, which could
be up to 250V _RMS_. In other words about 350V peak. I would not use a
cpaacitor rated at less than 630V DC, actually.
But it's easy to find capacitors rated for use in mains filters, and
that's what I would fit.
