Substitute Part Grouping Explanation

Substitute parts are identified strictly via exact matching of the following key parameters: FET type, technology, drain-to-source voltage (Vdss), continuous drain current (Id), Rds(on) (max), gate threshold voltage (Vgs(th)), gate charge (Qg), maximum Vgs, input capacitance (Ciss), power dissipation, mounting configuration, package dimensions, RoHS and REACH compliance, and operating temperature range. Substitution is valid only when all these characteristics align with the primary device, ensuring electrical and mechanical compatibility within the given product category.
