on “ASUS TUF Gaming A15 Laptop Repair – No Power” video the mosfet was shorted and was replaced by another number mosfet. Are the mosfets equivalent replacement? if so how did you know? thank you.
Across one motherboard, most of the time. For simplicity in assembly, most of the FETs (except where difference is needed or to save money) will be the same size part – Physical size, rating and type.
Across different models and brands, it can be all over the place – Different sizes, amp / voltage ratings, heat dissipation, and junction type.
Many manufacturers will offer parts of similar spec, generally if one finds one of the same size / rating / junction, it’ll drop in and function normally.
