I would like to know if there is a like for like replacement for the SP isolator?  ADUM3150BRSZ.


  • Hello Mr. Hansmann

    The ADuM3150BRZ is unique and there is not a pin for pin replacement.  The functionality can be replaced with multiple other chips, and there is the ADuM4150 which is the same functionality in a larger package with higher isolation ratings.

    It is not clear what you are aiming for by replacing this device, if you elaborate we can continue the discussion.  Do you need availability, functionality, or something else from a replacement?

    Best Regards,
