Substitute Part Grouping Explanation

Substitute parts for the FDV301N-F169 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• FET Type and Technology: N-Channel MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 25V
• Continuous Drain Current (Id) @ 25°C: 220mA
• On-State Resistance (Rds On): 4Ω @ 400mA, 4.5V
• Gate Threshold Voltage (Vgs(th)): 1.06V @ 250µA
• Gate Charge (Qg): 0.7nC @ 4.5V
• Maximum Gate Voltage (Vgs): ±8V
• Input Capacitance (Ciss): 9.5pF @ 10V
• Power Dissipation: 350mW
• Operating Temperature Range: -55°C to 150°C
• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Compliance: ROHS3 Compliant, MSL 1

The FDV301N-F169 is an obsolete variant of the base product FDV301. The primary substitute is the FDV301N, which maintains all electrical parameters and package specifications while offering active product status and significantly higher inventory availability.
