If they did provide you with the part number for the FET and you purchased it from Mouser it is absolutely guaranteed your unit will not operate to factory specifications. They test and scrape 90%+ of the devices. Not because they don't meet the manufacturers specification it is because they don't meet ARC's specifications. They can't return the rejected devices.
Nothing nefarious here. I've been to the factory and watched the process.
This is why a .15 cent FET from Mouser is $15 from ARC. It takes a lot of time to test, reject, select and match the devices. They don't sand off the numbers they color code them and of course that obscures the part number.
If this bothers someone then it is probably best to buy something else.
