Substitute Part Grouping Explanation

Substitute parts are selected based strictly on electrical and mechanical compatibility. The following allowed parameters are exact-matched or compatible: FET type (N-Channel), category (Transistors, FETs, MOSFETs), mounting type (Through Hole), package/case (TO-247-3 family), RoHS status, product status, drain to source voltage (800 V), continuous drain current @ 25°C, and key performance attributes including Rds(on), gate threshold voltage (Vgs(th)), gate charge (Qg), and input capacitance (Ciss). The substitute group consists of IXFH16N80P and SPW11N80C3FKSA1, which conform to substitution logic based on these key allowed parameters.

Engineering Selection Recommendations

All substitute parts (IXFH16N80P and SPW11N80C3FKSA1) are ROHS3 compliant and have an unlimited moisture sensitivity level (MSL 1). REACH status is unaffected across all compared parts. Both IXFH16N80P and the main APT8043BLLG are active; however, SPW11N80C3FKSA1 is not recommended for new designs according to the provided product status. Selection should only utilize active-status substitutes for continuity.
