Batboard

Need motorola transistor 48-869349 /m9349, its in power control board of a power supply, and Is there a substitue I could use in its place, And who is a good supply to deal with

RF parts may have it

Or the Rest of the Electronics Spots

Digikey/Mouser

Many component 'houses' do not have factory cross references to Motorola house numbered parts, it ends up as a crap shoot for many.

Circle-M used to have a fax-back line where you could look up a specific part using the house numbered part, and I used it a lot in the past, but I do not remember if it's still available, or active.

That's the best I can do on 'short' notice....sorry.
