Tayda looks like a good steer for a cheap PFET. But be aware that the on resistance of an IRF5305 is 60 milli-Ohms, which is 20 times more than the part Gordon was working with. So if your rig draws 10 Amps there will be a 10*0.060=0.6 volt drop across this PFET, and you may as well just use a big Schottky diode in series.
Also, IR/Infineon consider this part to be obsolete, so now only made by no-name second tier clone manufacturers. For example, these guys list the manufacturer as "various".
Not necessarily a bad thing, there are thousands of uBitx's out there with a clone no-name Nano, and the Nano is far more complicated than a PFET.
I've bought a bunch of stuff from Tayda at their alarmingly low prices, it all seems to work just fine.

If you're looking for a P-Channel MOSFET for a power switch then this may be able to use a IRF5305 - TO-220, 55V, 31A, 0.06Ohm RDS On @$0.78 each:
Tayda has a $5.00 minimum order and their USPS shipment is 8-16 days and low cost.? While they may not have everything, it's very low priced and good quality.
