2sk1290 substitute

[Old'n'Cranky]

Hi Guys.

Ok so I have an amp with several dead 2sk1290 power supply mosfets.

I have found a supplier in the uk, But I'm unsure if I should trust that they are genuine going by feedback.
I don't particularly wish to subject the board to the trauma of multiple solder cycles.

I'm also having trouble locating substitutes.
rs mouser digikey don't appear to have suitable parts from what I can see.
So far they either don't have the Id / Rds / pd, or they are an incorrect or uninsulated package.

The basic specs on the 1290 are;

N -Channel
Maximum Power Dissipation (Pd): 60 W
Maximum Drain-Source Voltage |Vds|: 60 V
Maximum Drain Current |Id|: 30 A
Maximum Junction Temperature (Tj): 150 °C
Maximum Drain-Source On-State Resistance (Rds): 0.045 Ohm
Package: MP25


If someone has two they are willing to sell me I would be very grateful, otherwise I will swap out all 8 with equiv's.
When I find an equiv that is

All help much appreciated.

What's wrong with the IRFIZ48? The PD is lower but the RDSon is much lower so they're likely to have less PD.
