    I have a blown Transistor out of an electric wheelchair and cannot find a
    listing or cross reference for the International Rectifier No. 9319 , any
    help would be appreciated , this is a TO-220 case Trans.

    I don't think this is a transistor, as IR made vanishingly few of
    them. More likely a voltage regulator or SCR.

    If you change your search parameters, this might help.

    Thanks for the help , yes the 9319 is the mfg. date and P/N is PMC-NE8 and
    yes I can't find it for the homebuilder and no cross reference , Phil L.

    Indeed it may be a thyristor; however I am currently using IR power
    mosfets in TO-220 cases. Your number may be a date code or house number too;
    please post _all_ identifying marks on the part for further research.

    That sure doesn't look like an IR part number; if the device was made
    by IR than that appears to be a customer's code. What brand is the controller?
    Most medical equipment service houses have cross references for all these
    parts (we have such a shop in our area that repairs wheelchair controllers
    and they certainly have manuals with component descriptions and cross-

    This site suggests that it is in fact a (MOS)FET:

    How old is the chair? That number looks suspiciously like a date code, and if
    so, it's absolutely useless as an identifying mark. It just states when the
    part was made.

    Any other characters/numbers on the part that might give us a clue? Have you
    tried contacting the manufacturer for replacement parts or identification of the

    As a last resort, contact an organization that services these chairs. They
    probably won't give you much advice, but it's worth a shot.

    One more last resort, you might have to bite a bullet and pay a service shop to
    repair it for you.
