I haven't been able to locate a 2SB1335A transistor. It is the +5V
pass transistor in a Mitsubishi ECU. Does anyone know where I might
find one (in Australia)? Failing that, can anyone suggest a suitable
substitute? Due to nature of the heatsinking, the replacement part
must be mechanically identical, ie it must come in a plastic package,
and the mounting hole must be in the same place. The last time I
repaired a similar ECU, I was fortunate to have a close substitute in
my spares box, but I can't remember its part number. :-(

The specs for the 2SB1335A appear to be PNP, Vceo=80V, Vcb=5V, Ic=10A,
and power rating is 50 Watt.

Thanks. Unfortunately the only parts that are readily available to me
are the BD244C and BD538. Both appear to be supplied in metal packages
which would compromise the heatsinking arrangements.
