IRFD014 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRFD014 is an N-Channel Metal Oxide Semiconductor Field Effect Transistor (MOSFET) rated for 60V drain-to-source voltage with a continuous drain current of 1.7A at 25°C. The device is housed in a 4-HVMDIP through-hole package and is designed for general-purpose switching applications requiring moderate voltage and current ratings.

The IRFD014 is classified as obsolete. Locating active production alternatives is necessary to ensure long-term component availability, supply chain continuity, and compliance with current manufacturing standards. The IRFD014PBF provides a direct functional equivalent with identical electrical specifications and active product status.

Substitute Part Grouping Explanation

Substitution of the IRFD014 is determined by electrical and mechanical parameter equivalence. The primary substitute, IRFD014PBF, maintains identical specifications across all critical parameters:

Electrical Equivalence Criteria:

• Drain-to-source voltage rating: 60V
• Continuous drain current: 1.7A at 25°C
• On-state resistance: 200mOhm at 1A, 10V gate drive
• Gate threshold voltage: 4V at 250µA
• Gate charge: 11nC at 10V
• Input capacitance: 310pF at 25V
• Power dissipation: 1.3W
• Operating temperature range: -55°C to 175°C

Mechanical Equivalence Criteria:

• Package type: 4-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Supplier device package: 4-HVMDIP

The IRFD014PBF is manufactured by the same supplier (Vishay Siliconix) and differs only in product status (Active vs. Obsolete) and RoHS compliance classification. No electrical or mechanical derating is required for this substitution.

Engineering Selection Recommendations

The IRFD014PBF is the direct functional equivalent of the IRFD014. Selection between these parts is determined by application requirements and regulatory compliance:

IRFD014PBF Selection Criteria:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance satisfies current environmental and regulatory requirements for new designs and manufacturing
• Identical electrical and mechanical specifications eliminate the need for circuit redesign or board layout modification
• Bulk packaging option provides flexibility for production volumes

IRFD014 Retention Criteria:

• Existing inventory of IRFD014 units may be used in legacy applications or repair scenarios where RoHS compliance is not mandated
• Obsolete status indicates no new production; existing stock should be consumed before depletion

For new designs, production builds, and applications subject to RoHS or environmental compliance requirements, IRFD014PBF is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can IRFD014PBF be used as a direct replacement for IRFD014 without circuit modification?

A: Yes. The IRFD014PBF maintains identical electrical specifications (Vdss, Id, Rds On, Vgs(th), Qg, Ciss, power dissipation, and operating temperature range) and mechanical package (4-DIP through-hole). No circuit redesign or board layout changes are required.

Q: What is the primary difference between IRFD014 and IRFD014PBF?

A: The IRFD014PBF is the active production variant with ROHS3 compliance. The IRFD014 is classified as obsolete and is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there any thermal or current derating considerations when substituting IRFD014PBF for IRFD014?

A: No. Both devices share identical power dissipation ratings (1.3W), continuous drain current (1.7A at 25°C), and operating temperature range (-55°C to 175°C). Thermal and current handling characteristics are equivalent.

Q: Is the 4-DIP through-hole package identical between both parts?

A: Yes. Both IRFD014 and IRFD014PBF use the 4-DIP (0.300", 7.62mm) through-hole package with 4-HVMDIP supplier device package designation. PCB footprints and lead spacing are identical.

Q: Which part should be selected for new product designs?

A: IRFD014PBF should be selected for new designs. Active product status ensures long-term availability, and ROHS3 compliance satisfies current manufacturing and environmental standards.

Q: Can IRFD014 inventory be used interchangeably with IRFD014PBF in production?

A: Yes, from an electrical and mechanical standpoint. However, RoHS compliance requirements for the end application must be evaluated. If RoHS compliance is mandated, IRFD014PBF is required.

Q: What is the gate charge specification, and does it affect switching performance?

A: Gate charge (Qg) is 11nC at 10V for both parts. This parameter determines the charge required to switch the device and affects gate drive circuit design. Identical specifications ensure equivalent switching performance.

Q: Are there any moisture sensitivity or handling differences between the two parts?

A: Both IRFD014 and IRFD014PBF have Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no special moisture control requirements during storage or handling.
