First, the AO3434 or the AO3434A can be used successfully in place of NO2. The AO3407 or AO3407A can be used successfully in place of PO3.

All four can be purchased at very low cost per unit from various Aliexpress suppliers.

Meanwhile, the AO3434A and AO3407A are also currently available from Digikey if preferred.

Meanwhile I hope the parts I posted a while back in response to the above request arrived safely and were put to good use :)
