Well the electrical specs are good. The only caveat is that the package dimensions are different and that the TO220 package is smaller than the original, however the package leads (pinout) are in the same positions. It won't be a drop-in type of repair as you will have to carefully bend the leads to fit the original hole spacing. I'm sure you will need an insulator under the device as well (a special material that can also conduct heat) also a plastic bush through which the mounting bolt goes, as with the TO220 package, the drain is connected electrically to the metal tab. I note that the TO3PB package is isolated from the drain. If you want a 'drop in' solution and your not familiar with installing such a device, I would keep looking for a MOSFET with the same TO3PB package, as well as good electrical specs as discussed.

Hope this helps, Phil.
