    So I blew some more IRG4PC50UD's. Digikey has them for ass-all price, and
    Allied is out of stock, so I ordered the suspiciously cheap but similar part
    IRG4PC50KD.

    Reading through the data sheets simultaneously, it looks like the KD is
    slightly worse performing, perhaps as if the UDs were selected for lower
    losses. Does this sound about right? Anyone have experience with this
    family?

    Looks about right to me. The cheaper 'KD part specs 10% higher
    saturation voltage, higher gate charge requirements, slower
    switching, and ~50% higher switching losses.

    Nope.
