IRF7241TR Equivalent & Substitute Parts Reference

Part Overview

The IRF7241TR is a P-Channel MOSFET manufactured by Infineon Technologies, rated for 40V drain-to-source voltage with 6.2A continuous drain current at 25°C. This device is packaged in an 8-SOIC surface mount configuration and is designed for applications requiring P-channel switching and amplification in low-voltage power management circuits.

The IRF7241TR carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for legacy systems or new designs requiring compatible performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF7241TR is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: P-Channel topology
• Package / Case: 8-SOIC (0.154", 3.90mm Width) surface mount configuration
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 150°C (TJ)
• Vgs (Max): ±20V gate voltage rating

Secondary Compatibility Parameters:

• Drain to Source Voltage (Vdss): Minimum 40V
• Current - Continuous Drain (Id) @ 25°C: Minimum 6.2A (Ta)
• Rds On (Max) @ Id, Vgs: Maximum 41mOhm @ 6.2A, 10V
• Power Dissipation (Max): Minimum 2.5W (Ta)

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical specifications) and Manufacturer Recommended Substitutes (compatible within application constraints).

Engineering Selection Recommendations

IRF7241TRPBF (Infineon Technologies) — Parametric Equivalent

The IRF7241TRPBF is the direct parametric equivalent of the IRF7241TR. Both devices share identical electrical specifications: 40V Vdss, 6.2A continuous drain current, 41mOhm Rds On, and 2.5W power dissipation. The IRF7241TRPBF differs only in product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus non-compliant). This part is supplied in Cut Tape (CT) & Digi-Reel® packaging and maintains full pin-for-pin and functional compatibility. Selection of IRF7241TRPBF is appropriate for applications requiring identical performance with improved supply chain availability and regulatory compliance.

ZXMP3A16N8TA (Diodes Incorporated) — Manufacturer Recommended Substitute

The ZXMP3A16N8TA is a manufacturer-recommended substitute with compatible but reduced electrical specifications. This device operates at 30V Vdss (versus 40V), delivers 5.6A continuous drain current (versus 6.2A), and dissipates 1.9W maximum power (versus 2.5W). The Rds On specification is 40mOhm @ 4.2A, 10V, which is marginally lower than the IRF7241TR. Gate charge is significantly reduced at 29.6nC @ 10V (versus 80nC), and input capacitance is lower at 1022pF @ 15V. The ZXMP3A16N8TA is suitable for applications where the reduced voltage and current ratings are acceptable and where lower gate charge and capacitance provide circuit advantages. Both substitute parts maintain identical package geometry, operating temperature range, and MSL rating. Both are ROHS3 compliant and REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can IRF7241TRPBF be used as a direct replacement for IRF7241TR?

A: Yes. The IRF7241TRPBF is a parametric equivalent with identical electrical specifications and pin configuration. The only differences are product status (Active versus Obsolete) and RoHS compliance level. No circuit modifications are required.

Q: What are the limitations of using ZXMP3A16N8TA as a substitute?

A: The ZXMP3A16N8TA has lower maximum ratings: 30V Vdss instead of 40V, 5.6A continuous drain current instead of 6.2A, and 1.9W power dissipation instead of 2.5W. Applications requiring the full 40V voltage rating or 6.2A current capacity cannot use this substitute. Verify that your circuit operates within the reduced specifications before selection.

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

A: Yes. All three parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layout and footprint compatibility are identical across all three devices.

Q: What is the difference between IRF7241TR and IRF7241TRPBF packaging?

A: IRF7241TR is supplied in standard packaging, while IRF7241TRPBF is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same 8-SOIC case. The packaging difference affects handling and tape reel specifications but does not impact electrical performance or PCB assembly compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, IRF7241TRPBF is the preferred choice due to Active product status, ROHS3 compliance, and identical electrical specifications. ZXMP3A16N8TA should be selected only when reduced voltage and current ratings are acceptable and when the lower gate charge provides specific circuit advantages.

Q: Are there any temperature or environmental differences between these parts?

A: All three parts share identical operating temperature ranges (-55°C to 150°C TJ) and MSL ratings (1 — Unlimited). Environmental performance is equivalent across all devices.

Q: Can I use ZXMP3A16N8TA in a 40V application?

A: No. The ZXMP3A16N8TA is rated for maximum 30V Vdss. Using this part in a 40V application exceeds its voltage rating and will result in device failure. Verify that your circuit operates at or below 30V before selecting this substitute.
