Hello, does anyone have experience with pads compatibility with the Kat 4 module?

My snare pad finally gave up after almost 3 years and I've been eyeing the Roland PDX-100, but I have no idea if it would work with it. does anybody know?

Also, if you could help me save my pad it would be greatly appreciated, i don't even know what I should look for to see if it's broken or what broke and what not.

Just to give you a little more context on what the issue is with the pad. For some reason only the rim sensor works in every hit, regardless of where i hit it even if it is in the dead center 0. Which leads me to believe that it's possible to save it and save me a hundred bucks.
