Substitute Part Grouping Explanation

Substitute MOSFETs are grouped based upon strict alignment of fundamental electrical and mechanical parameters derived from the main part specification. These include N-Channel type, MOSFET technology, similar drain-to-source voltage (Vdss), comparable continuous drain current (Id), consistent drive voltage and gate threshold values, similar Rds On, gate charge, input capacitance, and matching maximum power dissipation. Mechanical compatibility is maintained through through-hole mounting and TO-247-3 or its variant package forms. All substitutes listed are active, RoHS compliant, REACH unaffected, and have MSL 1 ratings.
