AUIPS2041R Equivalent & Substitute Parts

Part Overview

The AUIPS2041R is a Power Switch/Driver N-Channel 1:1 low-side switch manufactured by Infineon Technologies in TO-252AA (DPAK) packaging. This component is classified as obsolete, with 1.4A maximum output current and 100mOhm typical on-resistance. The part carries automotive-grade qualification (AEC-Q100) and operates across -40°C to 150°C junction temperature range.

Due to obsolete product status, equivalent and substitute parts are necessary for ongoing design support, production continuity, and system reliability. Active alternatives provide enhanced performance characteristics while maintaining electrical and mechanical compatibility within the specified parameter envelope.

Engineering Selection Recommendations

For 60V Load Voltage Applications (Direct Voltage Compatibility):

BTS3028SDLATMA1 and BTS3028SDRATMA1 provide the closest performance match with 5A output current, 28mOhm on-resistance, and identical 60V voltage rating. Both are active products with ROHS3 compliance and enhanced over-voltage protection. Selection between SDLATMA1 (Cut Tape & Digi-Reel) and SDRATMA1 (Cut Tape & Digi-Reel) depends on packaging and supply chain requirements.

BTS3046SDLATMA1 and BTS3046SDRATMA1 offer intermediate performance with 3.6A output current and 46mOhm on-resistance, maintaining 60V voltage compatibility. These are suitable for applications requiring moderate current handling with reduced on-resistance compared to the original part.

BTS3104SDRATMA1 maintains the closest on-resistance profile (104mOhm) to the original AUIPS2041R while providing 60V voltage rating and 2A output current capability. This option is appropriate for applications with minimal current margin requirements.

For 42V Load Voltage Applications (Reduced Voltage Designs):

BTS118DATMA1, BTS134DATMA1, BTS142DATMA1, and BTS3142DATMA1 are suitable only for systems with maximum load voltage of 42V. These active Infineon HITFET® series components provide progressive current and on-resistance improvements but operate at reduced voltage rating.

Cross-Manufacturer Alternative:

VND10N06TR-E (STMicroelectronics) is an active alternative with 6A output current and ROHS3 compliance. Voltage rating information is not provided in the specification data; electrical compatibility must be confirmed through detailed datasheet review before selection.

Frequently Asked Questions (FAQ)

Q: Can BTS3028SDLATMA1 or BTS3028SDRATMA1 be used as direct replacements for AUIPS2041R?

A: Yes, within the specified electrical and mechanical parameters. Both parts maintain the TO-252-3 DPAK package, 60V load voltage rating, 1:1 ratio, low-side N-channel configuration, and non-inverting on/off interface. Output current (5A) and on-resistance (28mOhm) exceed the original part specifications. Enhanced fault protection (added over-voltage detection) provides additional system reliability. Pinout compatibility must be confirmed through datasheet comparison.

Q: What is the difference between BTS3028SDLATMA1 and BTS3028SDRATMA1?

A: Both parts are electrically and mechanically identical with 5A output current, 28mOhm on-resistance, and 60V voltage rating. The difference is packaging format: SDLATMA1 is supplied in Cut Tape & Digi-Reel format, while SDRATMA1 is also Cut Tape & Digi-Reel. Selection depends on assembly line equipment compatibility and supply chain logistics.

Q: Can 42V-rated parts (BTS118DATMA1, BTS134DATMA1, BTS142DATMA1, BTS3142DATMA1) be used in 60V applications?

A: No. These parts are rated for maximum 42V load voltage. Using them in 60V applications exceeds the absolute maximum rating and will result in device failure or degraded reliability. Use only in systems with confirmed maximum load voltage of 42V or lower.

Q: Why is the AUIPS2041R obsolete?

A: Product status is determined by the manufacturer. Infineon has transitioned this part to obsolete status. Active alternatives within the HITFET® series (BTS3028, BTS3046, BTS3104, BTS3142) provide equivalent or superior performance with continued manufacturing support and ROHS3 compliance.

Q: Is the VND10N06TR-E (STMicroelectronics) a suitable alternative?

A: VND10N06TR-E maintains TO-252-3 DPAK packaging, 1:1 ratio, low-side N-channel configuration, and non-inverting interface. Output current (6A) and fault protection (current limiting, over-temperature, over-voltage) are compatible. Maximum load voltage specification is not provided in available data. Electrical compatibility, particularly voltage rating and on-resistance characteristics, must be confirmed through complete datasheet review before design implementation.

Q: What is the significance of RoHS3 compliance on substitute parts?

A: All active substitute parts carry ROHS3 compliance certification, indicating conformance to Restriction of Hazardous Substances Directive requirements. The original AUIPS2041R does not specify RoHS status. ROHS3-compliant alternatives ensure regulatory compliance for new designs and production batches.

Q: Can multiple substitute parts be used interchangeably in the same design?

A: No. Each substitute part has distinct electrical characteristics (current rating, on-resistance, voltage rating). Design implementation must select a single part number based on application load voltage, current requirements, and thermal constraints. Mixing part numbers in the same design is not recommended without explicit circuit analysis and thermal modeling.
