Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AUIPS7111STRL are identified based on the following critical parameters that determine functional equivalence:

• Package Compatibility: Both substitute parts maintain the TO-263-5 (D2PAK) package format, ensuring mechanical and thermal compatibility with existing PCB layouts.
• Output Configuration: All parts feature high-side N-Channel output with 1:1 input-to-output ratio and on/off interface control.
• Operating Temperature Range: Substitute parts maintain the -40°C to 150°C junction temperature range, supporting automotive and industrial applications.
• Compliance Standards: All parts are ROHS3 compliant with AEC-Q100 automotive qualification, meeting regulatory and quality requirements.
• Electrical Characteristics: Substitute parts operate within overlapping voltage and current specifications, with enhanced current ratings (17A vs. 10A) and improved fault protection features.

The BTS441RGATMA1 and BTS441TGATMA1 are functionally equivalent alternatives from Infineon's PROFET® series, differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The AUIPS7111STRL is classified as obsolete and should be replaced with active alternatives for new designs and production continuity. Both BTS441RGATMA1 and BTS441TGATMA1 are active products from Infineon's PROFET® series and provide direct functional substitution.

Selection Criteria:

• For Cut Tape & Digi-Reel® packaging: Select BTS441RGATMA1
• For Tape & Reel packaging: Select BTS441TGATMA1

Both substitute parts maintain ROHS3 compliance and are manufactured by the same supplier, ensuring supply chain consistency. The substitute parts feature enhanced fault protection capabilities including open load detection and over-voltage protection, providing improved system reliability compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can BTS441RGATMA1 and BTS441TGATMA1 be used interchangeably with AUIPS7111STRL?

A: Yes, both parts are functionally equivalent for high-side N-Channel switching applications. The difference between BTS441RGATMA1 and BTS441TGATMA1 is packaging format only (Cut Tape & Digi-Reel® versus Tape & Reel). PCB layout and electrical design remain unchanged.

Q: What are the key differences in electrical specifications?

A: The substitute parts feature a higher maximum output current rating (17A versus 10A) and higher on-resistance (15mOhm versus 6mOhm). The load voltage range is slightly narrower (4.75V ~ 43V versus 8V ~ 50V). Enhanced fault protection includes open load detection and over-voltage protection.

Q: Are the substitute parts compatible with existing PCB designs?

A: Yes. Both substitute parts use the identical TO-263-5 package format, maintaining mechanical and thermal compatibility with existing layouts. No PCB modifications are required.

Q: What compliance certifications apply to the substitute parts?

A: Both substitute parts are ROHS3 compliant. Automotive qualification status is not specified in the provided data.

Q: Why is the AUIPS7111STRL obsolete?

A: The original part is classified as obsolete by the manufacturer. The BTS441 series represents the current active product line for equivalent high-side N-Channel switching applications.
