    1N4001 and 2N4401

    For my startup controller I just realized I ordered a 1N4001 instead of a 2N4401, are these parts about the same in the way they work in such that you could substitute them in for each other.

    Nope, one is a diode, one is an NPN transistor. Not even the same type of device.
