Replacement for three terminal capacitor
It's only a single capacitor, not a 2 in 1 package.
The outer leads are internally connected as a feed-through.
From this Murata Doc:

So if you can't find a similar one to replace it with, you can loop a piece of wire between the outer 2 pins and connect a 2-terminal cap from the middle pin to that wire.
Pay attention to polarity !!
You will obviously lose the noise-suppression &amp; other characteristics that the correct three-terminal cap would have given you though.
