Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRF7811AVTRPBF is determined by electrical and mechanical parameter compatibility within the N-Channel MOSFET category. The primary substitution criteria are:

Electrical Compatibility Parameters:

• Drain-to-Source Voltage (Vdss) must equal or exceed 30V
• Continuous Drain Current (Id) must meet or exceed 10.8A at 25°C
• Maximum Gate Voltage (Vgs Max) must accommodate ±20V operation
• Operating temperature range must span -55°C to 150°C (TJ)
• Power dissipation capability must support 2.5W (Ta) minimum

Mechanical Compatibility Parameters:

• Mounting type must be Surface Mount
• Package must be 8-SOIC (0.154", 3.90mm Width) for direct PCB compatibility

Compliance Requirements:

• RoHS3 compliance status
• Moisture Sensitivity Level (MSL) of 1 (Unlimited)
• REACH unaffected status

The IRF8714TRPBF qualifies as a substitute part based on these criteria. This part maintains identical voltage and power ratings, exceeds the current specification, and shares the same package footprint and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The IRF8714TRPBF is the qualified substitute for the obsolete IRF7811AVTRPBF based on the following engineering criteria:

Electrical Equivalence: The IRF8714TRPBF maintains identical voltage ratings (30V Vdss) and power dissipation capability (2.5W Ta). The substitute part exceeds the continuous drain current specification, providing 14A versus the original 10.8A at 25°C. This increased current rating provides design margin without introducing electrical incompatibility.

Mechanical Compatibility: Both parts utilize identical 8-SOIC surface mount packaging with 0.154" (3.90mm) width, ensuring direct PCB footprint compatibility without layout modifications.

Compliance and Certification: The IRF8714TRPBF maintains full compliance with RoHS3 requirements, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's regulatory standing.

Product Status: The IRF8714TRPBF carries active product status from Infineon Technologies, ensuring ongoing availability and supply chain support, contrasting with the obsolete status of the IRF7811AVTRPBF.

Frequently Asked Questions (FAQ)

Q: Can the IRF8714TRPBF be used as a direct replacement for the IRF7811AVTRPBF without PCB modifications?

A: Yes. Both parts share identical 8-SOIC (0.154", 3.90mm Width) packaging, enabling direct PCB footprint compatibility without layout changes.

Q: What is the primary difference between these two parts?

A: The IRF8714TRPBF provides higher continuous drain current (14A versus 10.8A at 25°C) while maintaining identical voltage ratings (30V Vdss) and power dissipation (2.5W Ta). All other electrical and mechanical parameters remain equivalent.

Q: Are there any gate charge or on-resistance differences that affect circuit performance?

A: Yes. The IRF8714TRPBF exhibits lower gate charge (12 nC @ 4.5V versus 26 nC @ 5V) and lower on-resistance (8.7 mOhm @ 14A, 10V versus 14 mOhm @ 15A, 4.5V). These improvements result in faster switching characteristics and reduced conduction losses.

Q: Does the substitute part meet the same compliance requirements?

A: Yes. The IRF8714TRPBF is RoHS3 compliant, REACH unaffected, and carries MSL 1 (Unlimited) rating, matching the original part's regulatory compliance.

Q: Why is the IRF7811AVTRPBF listed as obsolete?

A: The IRF7811AVTRPBF is classified as obsolete by Infineon Technologies. The IRF8714TRPBF is the active product offering that provides equivalent or superior electrical performance in the same package form factor.

Q: What is the operating temperature range for both parts?

A: Both the IRF7811AVTRPBF and IRF8714TRPBF operate across -55°C to 150°C junction temperature (TJ), providing identical thermal operating specifications.

Q: Are there any input capacitance differences between these parts?

A: Yes. The IRF8714TRPBF has lower input capacitance (1020 pF @ 15V versus 1801 pF @ 10V), which may result in improved high-frequency switching performance in certain circuit topologies.
