Should be OK, why do you need to change it, is the previous one broken?

In that case, no problem, in fact you can use pretty much any Shimano mech/derailleur with Shimano shifters because it's the shifter that determines the gear indexing and not the mech.

When you get the new derailleur, make sure to adjust the limit screws correctly to stop it going to far in on the lowest gear, biggest sprocket, that should stop it going into the spokes, or too far out on the highest gear, smallest sprocket.

Check the alignment of the dérailleur hanger. This (probably) needs to be fixed! Depending on the damage it took, the frame might be done for, though.
