Is there a modern day replacement for an NTE50? Mouser reads that it is obsolete and I need to find one locally. I am troubleshooting a 6100 and the FAQ suggests to replace the MPSA56 (Q101) with an NTE50.
Thanks!

NTE says you can replace MPSA56 with NTE159. Their cross reference engine is very nice.

Mouser has the NTE159 in stock.

In my opinion, the NTE50 or 159 parts are junk. The MSPA56 is a better performer and is more reliable. I may be biased. I tend to be repulsed by anything NTE. They used to be ECG, which through the 70's and 80's were nothing but remarked factory rejects and cheap knock-off parts from China and Taiwan and the Philipines.
Q101 MPSU57 (*Q1) Ordered from Bob Roberts
*Q1 Original PN is MPSA56. Upgrade to the TO-202 packaged transistor MPSU57 noting the orientation of the leads. Other parts suitable for this location are NDSU57 and NTE50.
From my notes (based on swimming through all the FAQ's, "expert" opinion, manuals, and talking to some trusted sources who have worked on these things for years):
So...I have used the MPSA56.
That's from the regulator upgrade? MPSU57 over MPSA56 certainly helps, but I've still seen U57s blow... LV6100 is much easier![]()
