Substitute Part Grouping Explanation

The DMN2451UFDQ-13 has one identified parametric equivalent: DMN2451UFDQ-7. Both parts are classified as substitutes based on identical electrical and mechanical specifications across all critical parameters that determine functional compatibility.

Substitution is valid when the following parameters match exactly:

• Drain to Source Voltage (Vdss): 20V
• Continuous Drain Current (Id) @ 25°C: 1.1A (Ta)
• On-State Drain Resistance (Rds On): 200mOhm @ 200mA, 4.5V
• Gate Threshold Voltage (Vgs(th)): 1V @ 250µA
• Gate Charge (Qg): 0.7nC @ 4.5V
• Maximum Gate Voltage (Vgs): ±12V
• Input Capacitance (Ciss): 52pF @ 16V
• Power Dissipation: 500mW (Ta)
• Operating Temperature Range: -55°C to 150°C (TJ)
• Package Type: 3-PowerUDFN (U-DFN1212-3 Type C)
• Automotive Grade: AEC-Q101 qualified
• RoHS Compliance: ROHS3 Compliant

Both parts share the same base product number (DMN2451) and differ only in manufacturing date code or production batch designation, indicated by the suffix variation (-13 versus -7).
