There's a lot of different ones. You need the correct speeds and chainline, top or bottom swing.
You have also to check the big ring some are for smaller MTB gearing, others for big hybrid triples.
Most should "work" with a bit of fettling but if you choose the right one will be a lot better.
Here you can find the technical specs

My stepson's just got his stolen bike back (a Giant ATX 1), with a couple of parts missing, firstly the front brake caliper (no problem, I'll just get a Clarks mechanical disc caliper, cheap n cheerful), secondly, the front derailleur? Original spec was Shimano Tourney, it's 3x8, top pull, but there seems to be several models of 3x Tourney f/d, which do I go for?
Cheers
