TPS23753A: PMP8803 TL431 alternative

Part Number: TPS23753A
Other Parts Discussed in Thread: PMP8803, TL431LI


Is it possible to use TL431LIBCDBZ as an alternative to U3 TL431ACDBVR in PMP8803? 

I'm using the TL431LI part elsewhere in my design so I'd like to use this throughout. With the exception of the pinout/package differences, is it a drop in replacement and would there be any other changes in performance I'd need to test for? 

Many thanks

  • Hey Phil, 

    The TL431LI should be a drop in replacement. They share the same data sheet and same thresholds, so it should operate the same. 

    If this post answers your question, please indicate so by marking this thread as resolved. Thank you.
