    Hello,

    TI has a great cross-reference tool on our website that can be accessed via the "Products" menu on the main page here:

    This tool returned the closest match we have to UM3212DA as:

    Looking in the datasheet of the UM3212DA, we can see the package details for the DFN8:

     

    Opening the LSF0102, I find that we don't have an exact pin-to-pin match, but there are two very similar packages.

    (1) DCU has the same pinout and pin pitch, so could easily be designed to fit on the same pads as the UM3212DA, however it is larger. The pads would have to be extended to support both devices for the same socket.

    (2) DQE is smaller and has a smaller pin pitch. It would not be directly compatible (not pin-to-pin replacement), but would be a good replacement for the UM3212DA.
