PNP help - Original burns out in 3 months

PNP help

I figured out the pinouts.. Can someone point to me a better substitute.
The originals work fine after 3 months then it burns out again.

Maybe there is a better one out there?

PNP
1- Emitter
2- Base
3- Collector

hFE=292
Uf= 765m

That information doesn't really help. Do you know it's actual part number or alternatively, can you show the schematic it is used in.

can you show the schematic it is used in.

with details on voltage, load, etc

Try a heftier PNP like a 2N2905 in a TO-5 metal casing, for proviinng at least twice or triple the originals power spec.
The original is only borderline overloaded if its handling 3 months of use , if being in use daily ?

Describe device and where transistor is used. Maybe you should look elsewhere for source of problem.
