Substitute Part Grouping Explanation
Substitute parts in the MOSFET category are determined by matching key electrical and mechanical parameters, namely: drain-to-source voltage (Vdss), continuous drain current (Id), Rds On, gate-source voltage max (Vgs), threshold voltage (Vgs(th)), gate charge (Qg), input capacitance (Ciss), power dissipation, operating temperature range, grade, qualification, and package type. Only parts identical in these parameters and compliance certifications are accepted as substitutes.
