You do understand that MOSFETs are different from BJTs?

I'm wondering if I swap that in, along with the 2N7002, a 10K resistor, and a 0 ohm resistor? Here is the new IO expander I just found with the same footprint: https://www.digikey.com/product-detail/en/texas-instruments/PCF8574APWR/296-13107-1-ND/484523
