TMP431: looking for EMC1412 pin to pin 2nd source replacement

Part Number: TMP431
Other Parts Discussed in Thread: LM95245, TMP411, TMP401, TMP451

Hi Sir,

I am looking for EMC1412-A-ACZL-TR pin to pin 2nd source replacement. This is MSOP-8 package.

I found TMP431ADGKR is pin to pin replacement, could you help me to double check?

Or there is other recommended solution?

Thank you.



  • Hi Allen,

    They are hardware compatible, but not 100% software compatible. Both have extra features that the other does not. Basic functionality is the same, and intended to be 2nd source. Also see LM95245.

    TMP401, TMP411 would also be hardware compatible but without the beta compensation feature.

    TMP451 is quite close to the DFN package variant, but 1mm smaller. It also does not have beta compensation feature.
