Hello!

I having trouble finding the right film capacitor replacement for an IIci Astec PSU, especially the large 2.0 µF 250 VAC. My local supplier doesn’t have them, so I thought I use Mouser for this order or any other suggestion for that matter.

This is the entire capacitor list (red shows the ones I have trouble finding):

0.0033 µF Y 250 V (Film)    ⌀ 10 mm
0.0047 µF Y 250 V (Film)    ⌀ 10 mm
0.0047 µF Y 250 V (Film)    ⌀ 10 mm

0.047 µF X2 (Film)    ⌀ 15 mm
0.1 µF X2 250 V (Film)    ⌀ 20 mm

2.0 µF 250 VAC (630 VDC?) (Film)    ⌀ 27 mm
0.22 µF X2 50 V  (Film)  ⌀ 20 mm
10 µF 25 V     ⌀ 3 mm
10 µF 50 V     ⌀ 3 mm
1000 µF 16 V    ⌀ 4 mm
1000 µF 16 V    ⌀ 4 mm
2.2 µF 50 V    ⌀ 3 mm
2200 µF 10 V    ⌀ 6 mm
2200 µF 10 V    ⌀ 6 mm
2200 µF 16 V    ⌀ 4 mm
2200 µF 25 V    ⌀ 8 mm
47 µF 100 V    ⌀ 4 mm
47 µF 16 V     ⌀ 3 mm
470 µF 16 V    ⌀ 4 mm
470 µF 200 V    ⌀ 10 mm
470 µF 200 V    ⌀ 10 mm

I’ll check it out, thanks!
I'll be recapping mine this week. I accidentally ran out of solder and some of the film caps I ordered aren't the best fit so I'm going to try some others. I can probably remember to update the thread if it works or not.

Please update, and show me how you made them fit :)  
Finished my recapping and nothing blew up. Some of my film caps were much smaller than the old ones being replaced so what I did with those was mostly had 1 leg lined up with the hole and the other leg bent a couple times to fit the second hole. Had to make sure I ordered one with long leads. I have a video of all this but it'll take a day or two to finish it. Some Digikey part numbers I used:

399-13014-ND - KEMET 0.047uf

399-5876-ND - KEMET 4700pf

399-12519-ND - KEMET 0.1uf
