Explode?  Those are ceramics caps, right?  Are these the line inlet filter caps, or later on?  For line inlet, you need line rated caps, which have quite high voltage ratings for good margin.  Apart from that, I would think they should all work.  I've used Panasonic caps before, but Matsushita, Vishay and Kemet are also names I know and would use.  I don't know Evox or Iskra.
