I need a new transistor for my Q65 lamps on the CPU. The part on the board says TIP42 99244. When I look on Marco... are there different kinds of TIP42 or do any work? DE isn't on the list on the ad and the ad shows TIP42A. Does the 99244 on the old transistor mean anything important? If I am going to put an order in - I want to get the right part.
