    Due to long lead times we are looking for an alternative for the ADUM6421ABRNZ5. Is a one on one replacement possible without a lot of pcb redesign?

      Hi Cedric, 
      

      There is not another device pin-compatible with the ADUM6421ABRNZ5. Some layout changes would be needed. 
      

      The most similar functionality for the isolated dc/dc converter would be the ADuM5020/ADuM5028/ADuM6020/ADuM6028.
      

      The digital isolation would be similar to the ADuM141E.
      

      Regards,
      

      Jason
