I didn't order just a single type of part from this seller. I actually ordered the following 6 parts: 100pcs Si2302DS N-Channel MOSFET (SOT-23), 10pcs IRF3708 N-Channel MOSFET (TO-220), 100pcs Si2301DS P-Channel MOSFET (SOT-23), 10pcs NDP6020P P-Channel MOSFET (TO-220), 10pcs 6N137 optocoupler and 20pcs PC817C optocoupler. The package with my parts arrived pretty quickly. It contained all the correct parts I ordered in the correct quantity. The parts look good. I tested one of each of the MOSFETs with my multimeter and they tested ok. I didn't test the optocouplers, but I think they will work. Overall, I'm happy I got the parts I wanted.
