I earlier posted a link to Future, where it is a dollar less
I think.
No accounting for shipping differences, though. And Digikey
used to have a $25 minimum to skip another extra charge.
Might still be policy.

Nice try, Archie!
Answer the question!

I just looked it up on Digi-Key. It sure looks like it has the right
specifications.

I'm pretty sure this is a variant package (TO-126 like) of the
Fairchild HUF75344, a low R-on (0.008 ohm) 75A 55V N channel MOSFET.
Any similarly low-Ron MOSFET would probably sub OK.
Automotive manufacturers picked up big time on MOSFET's as
replacements for relays.
Tim.

You asking that question makes it obvious that you should not even be
anywhere near the electronics industry.

It's the second number on the package.. which is a power fet and
fits the app just fine..
I've seen inverted numbers like this many times on packages.

I thought that the whole thing is PWM regulated. Must be above 20kHz
though becaus I have never heard an audible tone like with trains and
other heavy electric motors...
