IRF7425TR MOSFET P-Channel Equivalent & Substitute Parts

Part Overview

The IRF7425TR is a P-Channel MOSFET manufactured by Infineon Technologies, rated for 20V drain-to-source voltage and 15A continuous drain current in a surface mount 8-SO package. This device is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing design support and procurement continuity. The IRF7425TR belongs to the HEXFET® series and is designed for applications requiring P-channel switching and amplification in compact surface mount configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IRF7425TR is determined by the following critical parameters:

Primary Matching Criteria:

• FET Type: P-Channel
• Drain to Source Voltage (Vdss): 20V minimum
• Continuous Drain Current (Id): 15A or greater at 25°C
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Power Dissipation: 2.5W or greater

Secondary Compatibility Factors:

• Rds On (Max): 8.2mOhm or lower at rated conditions
• Operating Temperature Range: -55°C to 150°C minimum
• Gate Charge (Qg): 130nC or lower
• Input Capacitance (Ciss): 7980pF or lower

Substitute parts are classified into two categories: parametric equivalents (identical electrical specifications) and manufacturer-recommended alternatives (functionally compatible with minor parameter variations).

Engineering Selection Recommendations

IRF7425TRPBF (Infineon Technologies) — Parametric Equivalent

The IRF7425TRPBF is the direct parametric equivalent of the IRF7425TR, offering identical electrical specifications including 20V Vdss, 15A continuous drain current, and 8.2mOhm Rds On. This part is currently in active production status with 35,100 units in stock. The primary distinction is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and RoHS compliance status (ROHS3 Compliant versus non-compliant). The IRF7425TRPBF is the preferred direct replacement for obsolete IRF7425TR applications requiring identical electrical performance and pin-compatible 8-SOIC packaging.

FDS4465 (onsemi) — Manufacturer-Recommended Alternative

The FDS4465 is a manufacturer-recommended substitute offering functional compatibility with minor parameter variations. This device maintains the 20V Vdss rating and 8-SOIC package footprint but operates at 13.5A continuous drain current (versus 15A) with 8.5mOhm Rds On (versus 8.2mOhm). The FDS4465 provides extended operating temperature range (-55°C to 175°C versus -55°C to 150°C) and is ROHS3 compliant. This substitute is suitable for applications where the 13.5A current rating meets design requirements and the lower Rds On differential is acceptable. The FDS4465 is currently in active production with 30,472 units in stock.

Frequently Asked Questions (FAQ)

Q: Can IRF7425TRPBF be used as a direct replacement for IRF7425TR?

A: Yes. The IRF7425TRPBF is a parametric equivalent with identical electrical specifications (20V Vdss, 15A Id, 8.2mOhm Rds On). Both devices use the same 8-SOIC package and pin configuration. The primary differences are packaging format and RoHS compliance status. Electrical performance and thermal characteristics are equivalent.

Q: What are the key differences between IRF7425TRPBF and FDS4465?

A: Both devices share 20V Vdss rating and 8-SOIC package compatibility. The IRF7425TRPBF provides 15A continuous drain current with 8.2mOhm Rds On, while the FDS4465 provides 13.5A with 8.5mOhm Rds On. The FDS4465 offers extended temperature range (-55°C to 175°C) and is manufactured by onsemi using PowerTrench® technology. Selection depends on whether the 13.5A current rating satisfies application requirements.

Q: Is the FDS4465 suitable for applications requiring 15A continuous drain current?

A: The FDS4465 is rated for 13.5A continuous drain current at 25°C, which is 1.5A lower than the IRF7425TR specification. Applications requiring the full 15A rating should use IRF7425TRPBF. The FDS4465 is appropriate for designs with maximum current requirements at or below 13.5A.

Q: Are all substitute parts available in the same package?

A: Yes. All three devices (IRF7425TR, IRF7425TRPBF, and FDS4465) use the 8-SOIC package with 0.154" width and 3.90mm dimensions. Pin configuration and PCB footprint are identical, enabling direct board-level substitution.

Q: What is the RoHS compliance status of each part?

A: IRF7425TR is RoHS non-compliant. Both IRF7425TRPBF and FDS4465 are ROHS3 compliant. For applications requiring RoHS compliance, either IRF7425TRPBF or FDS4465 must be selected.

Q: How do the gate charge specifications compare?

A: IRF7425TR and IRF7425TRPBF both specify 130nC gate charge at 4.5V. The FDS4465 specifies 120nC at 4.5V, representing a 7.7% reduction. Lower gate charge may reduce switching losses in high-frequency applications.

Q: What is the moisture sensitivity level for these devices?

A: All three devices are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
