IRF614S MOSFET N-Channel 250V 2.7A Equivalent & Substitute Parts

Part Overview

The IRF614S is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 250V drain-to-source voltage with a continuous drain current of 2.7A at 25°C. The device is housed in a TO-263 (D2PAK) surface mount package and is designed for general-purpose switching applications requiring moderate voltage and current handling.

The IRF614S carries an Obsolete product status, indicating that the manufacturer has discontinued production. This obsolescence necessitates identification of equivalent substitute components that maintain identical or compatible electrical and mechanical specifications to ensure continued system functionality and design continuity.

Substitute Part Grouping Explanation

Substitution of the IRF614S is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute component must satisfy the following criteria:

Electrical Equivalence Requirements:

• FET Type: N-Channel configuration
• Drain to Source Voltage (Vdss): 250V minimum
• Continuous Drain Current (Id) @ 25°C: 2.7A minimum
• Drive Voltage (Max Rds On): 10V
• Rds On (Max) @ Id, Vgs: 2 Ohm @ 1.6A, 10V
• Vgs(th) (Max) @ Id: 4V @ 250µA
• Gate Charge (Qg) (Max) @ Vgs: 8.2 nC @ 10V
• Vgs (Max): ±20V
• Input Capacitance (Ciss) (Max) @ Vds: 140 pF @ 25V
• Power Dissipation (Max): 3.1W (Ta), 36W (Tc)
• Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Equivalence Requirements:

• Mounting Type: Surface Mount
• Package / Case: TO-263-3, D2PAK (2 Leads + Tab)
• Supplier Device Package: TO-263 (D2PAK)

The IRF614SPBF meets all electrical and mechanical equivalence criteria and is identified as a direct substitute for the obsolete IRF614S.

Parameter Comparison

Engineering Selection Recommendations

The IRF614SPBF is the direct electrical and mechanical equivalent of the obsolete IRF614S. All critical parameters—voltage rating, current capacity, on-resistance, gate charge, and thermal characteristics—are identical across both components.

Compliance Advantage: The IRF614SPBF carries ROHS3 compliance status, whereas the IRF614S is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the IRF614SPBF provides full compliance while maintaining complete functional equivalence.

Product Status Consideration: The IRF614SPBF is designated as Last Time Buy, indicating limited availability. For new designs or long-term production requirements, component procurement planning should account for this status.

Packaging: The IRF614SPBF is supplied in Tube packaging, whereas the IRF614S packaging specification is not provided. Both components use the identical TO-263 (D2PAK) surface mount package, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the IRF614SPBF be used as a direct replacement for the IRF614S in existing designs?

A: Yes. The IRF614SPBF is electrically and mechanically identical to the IRF614S across all specified parameters. No circuit modifications, PCB layout changes, or design alterations are required for substitution.

Q: What is the difference between IRF614S and IRF614SPBF?

A: The primary differences are product status and RoHS compliance. The IRF614S is Obsolete and RoHS non-compliant. The IRF614SPBF is Last Time Buy and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any thermal or performance differences between these parts?

A: No. Both components have identical power dissipation ratings (3.1W at Ta, 36W at Tc), operating temperature ranges (-55°C to 150°C), and all electrical characteristics including on-resistance, gate charge, and capacitance.

Q: What is the packaging difference, and does it affect PCB assembly?

A: The IRF614SPBF is supplied in Tube packaging for automated assembly processes. Both components use the TO-263 (D2PAK) surface mount package with identical pinout and footprint. No PCB modifications are necessary.

Q: Is the IRF614SPBF suitable for new product designs?

A: The IRF614SPBF is suitable for new designs with the understanding that it carries Last Time Buy status. For applications requiring long-term component availability, alternative N-Channel MOSFETs with higher production volumes should be evaluated for future design cycles.

Q: Does the ROHS3 compliance of IRF614SPBF affect circuit performance?

A: No. RoHS compliance is a manufacturing and material standard that does not alter electrical performance or functional characteristics. The IRF614SPBF maintains identical electrical behavior to the IRF614S.

Q: Can both parts be used interchangeably in the same production batch?

A: Yes. Both components are electrically and mechanically equivalent. However, due to Last Time Buy status of the IRF614SPBF, long-term supply consistency should be verified with the component supplier before committing to mixed-source production.
