IRLD024 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRLD024 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 2.5A continuous drain current at 25°C. The device is housed in a 4-HVMDIP through-hole package and dissipates a maximum of 1.3W. The IRLD024 is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support, maintenance, and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Substitute Part Grouping Explanation

Substitute parts for the IRLD024 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• FET Type: N-Channel
• Drain to Source Voltage (Vdss): 60V
• Continuous Drain Current (Id) @ 25°C: 2.5A (Ta)
• Rds On (Max) @ 1.5A, 5V: 100 mOhm
• Gate Threshold Voltage (Vgs(th)) @ 250µA: 2V
• Gate Charge (Qg) @ 5V: 18 nC
• Input Capacitance (Ciss) @ 25V: 870 pF
• Power Dissipation (Max): 1.3W (Ta)
• Operating Temperature Range: -55°C to 175°C (TJ)

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: 4-DIP (0.300", 7.62mm)
• Supplier Device Package: 4-HVMDIP

The IRLD024PBF is a direct substitute manufactured by Vishay Siliconix under the same base product number. It maintains identical electrical and mechanical specifications while differing only in packaging format (Tube) and product status (Last Time Buy vs. Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The IRLD024PBF is a direct electrical and mechanical equivalent to the IRLD024. All critical electrical parameters—including Vdss, Id, Rds On, Vgs(th), Qg, Ciss, and power dissipation—are identical. The devices share the same 4-DIP through-hole package footprint and are both manufactured by Vishay Siliconix under the same base product number.

Compliance Considerations:

The IRLD024 is classified as RoHS non-compliant, while the IRLD024PBF is ROHS3 compliant. For applications subject to RoHS regulations or requiring compliance with modern environmental standards, the IRLD024PBF is the appropriate selection. Both devices maintain REACH Unaffected status and EAR99 export classification.

Product Status:

The IRLD024 is obsolete, whereas the IRLD024PBF carries Last Time Buy status, indicating limited future availability. For new designs or long-term production requirements, the IRLD024PBF should be prioritized to ensure supply continuity.

Packaging:

The IRLD024PBF is supplied in Tube packaging, which may differ from the original IRLD024 packaging format. Verify packaging compatibility with assembly equipment and procurement workflows before implementation.

Frequently Asked Questions (FAQ)

Q: Can the IRLD024PBF replace the IRLD024 in existing circuits?

A: Yes. The IRLD024PBF is electrically and mechanically identical to the IRLD024. All electrical parameters, including voltage rating, current rating, on-resistance, and thermal characteristics, are matched. The 4-DIP through-hole package footprint is identical, enabling direct PCB-level substitution without circuit modification.

Q: What is the difference between the IRLD024 and IRLD024PBF?

A: The primary differences are product status and compliance certification. The IRLD024 is obsolete and RoHS non-compliant, while the IRLD024PBF is Last Time Buy and ROHS3 compliant. Electrically and mechanically, the devices are identical. The IRLD024PBF is supplied in Tube packaging.

Q: Why is the IRLD024 listed as obsolete?

A: The IRLD024 has reached end-of-life status with the manufacturer. The IRLD024PBF, sharing the same base product number and specifications, represents the current equivalent offering and should be used for new designs and ongoing production.

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

A: No. Both devices operate across the same temperature range (-55°C to 175°C TJ) and dissipate a maximum of 1.3W. Thermal performance and switching characteristics are identical.

Q: Does the Tube packaging of the IRLD024PBF affect compatibility?

A: Tube packaging affects handling, storage, and assembly logistics but does not affect electrical or mechanical compatibility. Verify that your assembly equipment and procurement processes accommodate Tube packaging before implementation.

Q: Are both parts suitable for high-reliability applications?

A: Both devices are manufactured by Vishay Siliconix and meet the same electrical specifications. The IRLD024PBF offers the advantage of ROHS3 compliance, which may be required for certain high-reliability or regulated applications. Consult application-specific requirements and supplier documentation for reliability certifications.

Q: Can I use the IRLD024PBF in a design originally specified for the IRLD024?

A: Yes. The IRLD024PBF is a direct substitute. No circuit redesign, PCB layout modification, or gate drive circuit changes are required. The identical electrical parameters and package footprint ensure drop-in compatibility.
