Alternate for FQPF9N50

The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement. Please review the suggested part to ensure it will work for your application.
this mosfet is obsolete having investigate substitutes, would you check these as substitutes: STP9nk50zfp or stp9nk50z.
There seems to be a mistake on zfp having 7 amp rating and .89 ohms would produce about 45watts but dissipate 30 watts?
The ratings (all) of 50Z exceed those of obsolete part?

I found no topic on this obsolete Mosfet under this Forum. The directs want to sell to many!

The below link shows the in-stock options I had found that you would be able to order small quantities of.
Please review for your needs.
