IRF614 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRF614 is an N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) rated for 250V drain-to-source voltage with a continuous drain current of 2.7A at 25°C. The device is packaged in a TO-220AB through-hole configuration and is rated for 36W maximum power dissipation. The IRF614 is classified as obsolete, making identification of active equivalent parts necessary for ongoing design support and procurement. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability in existing circuit designs.

Substitute Part Grouping Explanation

Substitution of the IRF614 is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Drain to Source Voltage (Vdss): 250V
• Continuous Drain Current (Id) @ 25°C: 2.7A (Tc)
• On-State Drain Resistance (Rds On): 2 Ohm @ 1.6A, 10V
• Gate Threshold Voltage (Vgs(th)): 4V @ 250µA
• Power Dissipation (Max): 36W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Equivalence Criteria:

• Package Type: TO-220-3
• Mounting Type: Through Hole
• Supplier Device Package: TO-220AB

Substitute parts must match all specified electrical parameters and maintain identical mechanical packaging to ensure direct pin-for-pin and functional replacement without circuit modification.

Engineering Selection Recommendations

The IRF614PBF is a direct electrical and mechanical equivalent to the IRF614. Both parts are manufactured by Vishay Siliconix and share identical electrical specifications across all critical parameters including Vdss, Id, Rds On, Vgs(th), and power dissipation ratings.

The primary distinction between the two parts is product status and regulatory compliance. The IRF614 is classified as obsolete, while the IRF614PBF maintains active product status. The IRF614PBF is ROHS3 compliant, whereas the original IRF614 is RoHS non-compliant. This compliance difference makes the IRF614PBF the appropriate selection for new designs and applications requiring adherence to current environmental and regulatory standards.

Both parts are supplied in identical TO-220AB through-hole packaging, ensuring mechanical compatibility and direct pin-for-pin replacement without PCB modification or circuit redesign.
