I have a number of CMB16D controllers that I purchased 2nd hand and I need to replace a few Mosfets. Can I substitute the newer FQP30N0L mosfet for the existing FFP30N06LE 60V 30A TO-220AB Mosfet.?? Also, I am ok with soldering, but one of the boards looks like the previous owner had a hell of a time getting a mosfet out and has killed some of the track leading to the Mosfet. I think I can link some wires to rectify the path of the circuit board that has lifted. Is there an easy way of removing the mosfet without damaging the board.? Too much heat will kit the circuit track. Not enough heat wont melt the solder. it seems to be a fine line. I do have solder wick.
