I need to replace a MJ 423 transistor (TO3), However, the part is obsolete. Can you recommend a replacement?
I could not find anything in the 10A collector current. I found an 8 amp version with part number 1514-2N6545PBFREE-ND . That is the closest I can find. Not sure if you have the full 10A going through the original part or not. You can review it to see if you can make it work. Unfrotunately this can style is not used or made as often anymore. Most of the options I find are obsolete. Sorry. This is the best I found.
My 1988 SAMS semiconductor replacement guide says that NTE385 is a suitable substitute.
Thank you Gentlemen! Parts order inbound!
