    Welcome to AAC.

    There are quite a few options for MOSFETs. If you're trying to find a close match because you need to stick with the same package size, go to Digikey or Mouser, search single FET, then choose all TO-3xx package sizes. From there, you can select the voltage you need and the current. You can also narrow down by Rds and so on. A quick search for a TO-3xx package rated at 400V turned up this on Digikey. I'd suggest comparing the specs and dimensions of your old MOSFET with any new ones you're considering using the datasheets to be sure it will fit and meet your requirements.
