Part Number: LM35

Hello,

is there a way to tell the difference between LM35DT and LM35DT/NOPB. The data sheet shows both parts have the same device markings. 

Thank you, 

Gary

    Dear Gary - 

    Thanks for the post and welcome to E2E! 

    The -NOPB suffix indicates the device is lead-free, as the lead finish on the -DT variant is SnPb, whereas the -NOPB variant lead finish is Sn. Otherwise they are functionally the same device.
