Substitute Part Grouping Explanation

Substitution is determined exclusively by matching the following mandatory parameters: manufacturer part number, FET type, technology, drain to source voltage (Vdss), continuous drain current (Id), drive voltage, Rds On, threshold voltage (Vgs(th)), gate charge, maximum gate-source voltage (Vgs), input capacitance, maximum power dissipation, operating temperature, mounting type, package/case, RoHS status, and REACH status. Only parts meeting all these criteria are considered direct equivalents in this MOSFET transistor category.
