Hello to all
I have an old circuit board from the late 70’s that has transistors marked as Motorola 48s62 026 and I need a replacement part number.
Schematics diagram calls out for bveco-60 p/n 48s62 for use in the 28 volt system
A similar 12volt system calls out for bveco-40 p/n 48s42 for use in a 14 volt system. The transistor used in the 14 volt system is also identified as a 2N3116 npn transistor.
Unfortunately I need the transistor for the 28 volt configuration.
Any help you could provide will be greatly appreciated.

Hello Skycootie, Welcome to the TechForum.
I am sorry, but I was not able to find much information on the part numbers you gave for those Transistors. If the 14 and 28 Volt systems are similar I did piece a little together.
The common thing that might be similar would be the package type which could be the TO-18.
With that I did find some options that should be able to work for the 28 volt system. The only thing is I was unable to locate all the specs so for example the Collector current I am not sure about.
Please look at These Options.
Again the Voltage should be ok for it. I am not sure what is fully required for the current rating.
Please take a look at these and see if any would work for you.
If you have any questions Please let us know.
Best regards Ken
That part number isn’t in my 1970’s & 80s transistor substitution books.
A Google search on the part number indicates it was used in aviation systems and a few aviation replacement parts suppliers appear to have it available.
