Default DV-PF4E(UK) Power suppy repair

Hi
I'm trying to repair an internal power supply in a Hitachi DV-PF4E video/dvd combi player.

I've narrowed the fault down to Q1001 a N channel mosfet (2SK3566) which seems to be shorted, when powering the power suppy this takes out resistor R1043.

I don't have any of these mosfets but do have some FDPF5N50UT's would this be a suitable replacement?

I've attached the schematic for the DV-PF4E the power supply section being on page 88, I've also attached the datasheets for the mosfets.
