Substitute Part Grouping Explanation

The substitute part listed, DMP3097LQ-7, is identified as a parametric equivalent for DMP3097L-7 based strictly on the following parameters: P-Channel MOSFET type, MOSFET technology, maximum Vdss of 30 V, continuous drain current of 3.9A at 25°C, comparable drive voltage, same Rds On value at identical current and gate-source voltage, matching threshold voltage, gate charge, input capacitance, and maximum power dissipation. Both parts share identical surface mount package formats (SOT-23-3 family) and compliance statuses. These directly matching parameters are the basis for a strict substitution.
