Digikey filters are great. Use the pin spacing, and look for something
rated for 105C from Panasonic. Make sure the outside diameter and length
aren't so much larger that it doesn't fit, but nobody can do that for you
without seeing the board. Always specify "in stock" in the search as well.

Initially when Digikey opened up, Panasonic was the only capacitor
manufacturer that they carried, so I just got in the habit of using them
from Digi-Key. Other vendors are fine but I tend to buy Panasonic all other
things being equal.

I did a long-life stress test on electrolytics a few years back.
Panasonic, Rubycon and Nichicon were the top of the heap, with not
much to choose between them. The 105C rating is a good idea.
