    Want to change D2PAK footprint with TO263-3 on Orcad/Allegro PCB Editor

    I have a PCB *.BRD file. No schematic no netlist. On board 03 D2PAK footprint placed U28, U29, U30. I want to replace a only U29 footprint D2PAK with To263-3. Any body know the procedure to replace the footprint without schematic and netlist.

    Delete d2pak footprint from board file and place your to263-3 footprint in your library path with the name what you given earlier for d2pak then place it manually in your board file then follow logic->assign refdes-> go to options->enter u29 then click on manually place footprint, do not refresh the footprints after this process

    1.first you delete d2pak(u29) on your board file.
    2.place "to263-3" manually on board file.
    3.Then follow this "logic->assign refdes-> go to options->enter u29 then click on manually placed footprint(tos63-3)"
    4.Make sure that both the components have same pin numbers.
