Default Substitute cap

Hi all,

I have a blown cap from an x-ray power supply. Here is all the writing on it:

1000V-/500v~MP
40/070/56

RIFA T6
PME 261 JA

6800 pF


I can't find the same cap so I was wondering if anyone knew if there was a good substitute for it. How far off 1000v can I go, and how far off 6800 pF? Also, it's a paper film capacitor - if I replaced the same spec with a different type of film capacitor that wasn't paper, would that cause problems?

Thanks Pete. I had seen the Mouser one but there was a minimum order of $1200 for that part!! The Digikey looks promising though so thanks for that.
