TPMS Sensors

OK,

I am trying to figure out TPMS sensors for a second set of wheels.

There are no compatible parts available for a 2021, so I went back a year.

Ford shows 2 part numbers compatible for a 2020 ST.

TPMS Sensor - Ford (JX7Z-1A189-C)

Tire Pressure Monitoring System Sensor - Ford (JX7Z-1A189-A)

So my questions are...

What's the difference between the 2 items?

Why are neither of them compatible with a 2021?

And are there aftermarket options that would work just as well?

Look up what MHz the 2021 sensors are then any sensor that matches will work. I wanna say 2020 is 315 MHz

Of course you knew. LOL! Thanks again, as always!
