Substitute Part Grouping Explanation

Substitution eligibility for the DMN67D7L-7 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

FET Type: N-Channel
Drain to Source Voltage (Vdss): 60V minimum
Package / Case: SOT-23-3 or equivalent footprint (TO-236-3, SC-59)
Mounting Type: Surface Mount
Operating Temperature Range: -55°C to 150°C (TJ)
RoHS Status: ROHS3 Compliant

Performance Envelope Parameters:

Continuous Drain Current (Id): 210mA or greater
Rds On (Max): 5 Ohm or lower @ specified conditions
Vgs(th) (Max): 2.5V or lower @ 250µA
Power Dissipation (Max): 570mW or greater

Substitute parts must satisfy all mandatory criteria and maintain performance within or superior to the specified envelope. Parts with higher current ratings, lower on-resistance, or greater power dissipation capability are acceptable as functional equivalents.
