Banda DSP 3K mosfet replacement

[D013137d]

Hello all, I'm currently working on a Banda DSP 3k amplifier that is run by "irfb448" mosfets in the power supply section. None of the reputable distributors carry it (Mouser, Digikey, Arrow, Newark etc...). Does anyone know of a suitable replacement for it?

AllTransistions.com doesn't even recognize that part number.....

Thanks!

I can't find the datasheet. The following site has 40v and 175A.

The csd18502kcs has similar specs and is used in some Brazilian amplifiers. Someone else may have a more definitive answer.
