IRFR020 Equivalent & Substitute Parts

Part Overview

The IRFR020 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with 14A continuous drain current in a surface mount DPAK package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within acceptable parameter ranges for the same application category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRFR020 is determined by the following critical parameters: drain-to-source voltage rating (Vdss), continuous drain current capacity (Id), on-state resistance (Rds On), gate threshold voltage (Vgs(th)), and package compatibility. All substitute parts must maintain the 60V Vdss rating and support the required drain current within specified thermal conditions. The DPAK package footprint is maintained across all listed substitutes to ensure mechanical compatibility.

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical or near-identical electrical specifications and the same DPAK package, enabling direct replacement without circuit modification.

Functional Alternatives: Parts with the same voltage rating and package but differing current ratings or thermal characteristics, suitable for applications where the exact current specification is not critical to circuit operation.

Parameter Comparison

Engineering Selection Recommendations

IRFR024PBF (Vishay Siliconix): This part is the primary parametric equivalent to the IRFR020, offering identical electrical specifications including 60V Vdss, 14A continuous drain current, 100mOhm Rds On, and 25nC gate charge. The IRFR024PBF is manufactured by the same supplier and maintains the same DPAK package. The part is currently in active production status with ROHS3 compliance, addressing the obsolescence of the original IRFR020. This substitute is suitable for direct replacement in existing designs.

STD12NF06T4 (STMicroelectronics): This part provides a functional alternative with 60V Vdss and 12A continuous drain current, representing a 14% reduction in current rating compared to the IRFR020. The STD12NF06T4 maintains the same DPAK package and 100mOhm Rds On specification. Gate charge is reduced to 12nC, and input capacitance is reduced to 315pF, resulting in improved switching performance. Power dissipation capability is increased to 30W (Tc). This part is active and ROHS3 compliant. Selection of this part is appropriate for applications where the 12A current rating is sufficient and improved thermal performance is beneficial.

RSD080N06TL (Rohm Semiconductor): This part provides a functional alternative with 60V Vdss and 8A continuous drain current, representing a 43% reduction in current rating. The RSD080N06TL uses a CPT3 package variant of the TO-252-3 footprint. On-state resistance is reduced to 80mOhm at 8A, and gate charge is reduced to 9.4nC. This part is active and ROHS3 compliant. Selection of this part is appropriate only for applications where the 8A current rating is sufficient and the lower current requirement justifies the reduced performance envelope.

All substitute parts maintain the 60V voltage rating and surface mount DPAK-compatible packaging. Selection between substitutes depends on application current requirements and thermal design constraints.

Frequently Asked Questions (FAQ)

Q: Can the IRFR024PBF be used as a direct replacement for the IRFR020?

A: Yes. The IRFR024PBF maintains identical electrical specifications including 60V Vdss, 14A continuous drain current, 100mOhm Rds On, and 25nC gate charge. Both parts use the DPAK package. The IRFR024PBF is currently in active production with ROHS3 compliance, making it the primary substitute for the obsolete IRFR020.

Q: What are the key differences between the STD12NF06T4 and the IRFR020?

A: The STD12NF06T4 has a reduced continuous drain current rating of 12A compared to 14A on the IRFR020. Gate charge is reduced to 12nC (from 25nC), and input capacitance is reduced to 315pF (from 640pF). Power dissipation capability is increased to 30W (Tc). Both parts maintain 60V Vdss and 100mOhm Rds On. The STD12NF06T4 is suitable for applications where the 12A current rating is adequate.

Q: Is the RSD080N06TL suitable for all applications using the IRFR020?

A: No. The RSD080N06TL has a reduced continuous drain current rating of 8A, representing a 43% reduction from the IRFR020's 14A rating. This part is suitable only for applications where the 8A current specification is sufficient. The RSD080N06TL uses a CPT3 package variant, which maintains TO-252-3 footprint compatibility but may have different lead geometry.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The IRFR024PBF, STD12NF06T4, and RSD080N06TL are all ROHS3 compliant. The original IRFR020 is RoHS non-compliant. Selection of any substitute part addresses RoHS compliance requirements for new designs and procurement.

Q: Do all substitute parts use the same package as the IRFR020?

A: The IRFR024PBF and STD12NF06T4 use the DPAK (TO-252-3) package identical to the IRFR020. The RSD080N06TL uses a CPT3 package variant, which is also a TO-252-3 footprint variant. All three parts are surface mount and maintain mechanical compatibility with DPAK footprints.

Q: What is the operating temperature range difference between substitutes?

A: The IRFR020 and IRFR024PBF operate from -55°C to 150°C (TJ). The STD12NF06T4 extends the upper limit to 175°C (TJ). The RSD080N06TL specifies only the upper limit of 150°C (TJ). Selection should consider application temperature requirements.

Q: How do gate charge specifications affect circuit design?

A: Gate charge (Qg) determines the energy required to switch the MOSFET. The IRFR020 and IRFR024PBF require 25nC at 10V. The STD12NF06T4 requires 12nC, and the RSD080N06TL requires 9.4nC. Lower gate charge reduces driver power dissipation and enables faster switching. Substitutes with lower gate charge may improve circuit efficiency but do not affect basic switching functionality.

Q: What inventory status should be considered for procurement?

A: The IRFR020 has 50,300 pieces in stock but is obsolete. The IRFR024PBF has 18,700 pieces in stock and is active. The STD12NF06T4 has 1,940 pieces in stock and is active. The RSD080N06TL has 10,465 pieces in stock and is active. For new designs, selection should prioritize active parts with adequate inventory.
