IRF9952 Equivalent & Substitute Parts

Part Overview

The IRF9952 is an N and P-Channel MOSFET array manufactured by Infineon Technologies, designed for logic-level gate applications with a maximum drain-source voltage of 30V. This dual-channel configuration integrates both N-channel and P-channel MOSFETs in a single 8-SOIC surface mount package, delivering continuous drain currents of 3.5A and 2.3A respectively at 25°C.

The IRF9952 carries an obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this MOSFET array configuration.

• On-resistance (Rds On): 100mOhm @ 2.2A, 10V
• Gate threshold voltage (Vgs(th)): 1V @ 250µA
• Gate charge (Qg): 14nC @ 10V
• Input capacitance (Ciss): 190pF @ 15V
• Maximum power dissipation: 2W
• Operating temperature range: -55°C to 150°C

Mechanical Parameters (Required for Physical Compatibility):

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Configuration: N and P-Channel dual MOSFET array

Compliance and Status Parameters:

• Manufacturer: Infineon Technologies
• Series: HEXFET®
• Base product number: IRF995

Parts meeting all electrical, mechanical, and configuration requirements are classified as direct substitutes. Packaging variations (such as Tape & Reel versus bulk) do not affect electrical equivalence but may impact procurement and handling specifications.

Engineering Selection Recommendations

IRF9952TRPBF as Direct Substitute:

The IRF9952TRPBF is a direct electrical and mechanical equivalent to the IRF9952. All critical electrical parameters—including voltage rating, current specifications, on-resistance, gate characteristics, and thermal operating range—are identical. The package type, mounting method, and dual N/P-channel configuration are unchanged.

The primary distinction between these parts is product status and compliance:

• IRF9952: Obsolete product status with RoHS non-compliant classification
• IRF9952TRPBF: Active product status with ROHS3 compliance

For new designs or ongoing production requiring regulatory compliance with RoHS3 standards, the IRF9952TRPBF is the appropriate selection. The packaging format difference (Tape & Reel versus bulk) reflects standard supply chain practices and does not affect electrical performance or circuit functionality.

Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring consistent regulatory treatment across supply chain operations.

Frequently Asked Questions (FAQ)

Q: Can IRF9952TRPBF be used as a direct replacement for IRF9952 in existing designs?

A: Yes. The IRF9952TRPBF is electrically and mechanically identical to the IRF9952. All electrical parameters, package dimensions, and pin configurations match exactly. The substitute part operates within the same voltage, current, and temperature specifications without circuit modification.

Q: What is the difference between IRF9952 and IRF9952TRPBF?

A: The IRF9952TRPBF differs from the IRF9952 in three non-electrical aspects: product status (Active versus Obsolete), RoHS compliance (ROHS3 Compliant versus RoHS non-compliant), and packaging format (Tape & Reel versus bulk). Electrical performance and physical package dimensions are identical.

Q: Why is the IRF9952 marked as obsolete?

A: The IRF9952 carries an obsolete product status designation. The IRF9952TRPBF, which shares identical electrical specifications, is the active equivalent maintained by Infineon Technologies for ongoing supply and support.

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

A: No. Both parts operate across the identical temperature range (-55°C to 150°C) and deliver the same electrical performance. Maximum power dissipation, on-resistance, and all switching characteristics are equivalent.

Q: Does the Tape & Reel packaging of IRF9952TRPBF affect circuit performance?

A: No. Tape & Reel packaging is a supply format used for automated assembly processes. It does not alter the electrical characteristics, performance, or functionality of the MOSFET array. The die and internal circuitry are identical to bulk-packaged versions.

Q: Can I mix IRF9952 and IRF9952TRPBF in the same production batch?

A: Yes, from an electrical and functional standpoint. However, procurement and inventory management practices typically maintain consistency within a production run. The active status and RoHS3 compliance of IRF9952TRPBF make it the preferred choice for new production orders.

Q: What compliance certifications apply to both parts?

A: Both parts carry identical REACH (REACH Unaffected) and ECCN (EAR99) classifications. The distinction is RoHS compliance: IRF9952TRPBF is ROHS3 Compliant, while IRF9952 is RoHS non-compliant. Moisture sensitivity level (MSL 1 - Unlimited) is identical for both.
