Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AUIPS2041LTR is determined by the following critical parameters:

• Output Configuration & Type: Low-side N-Channel switching topology
• Ratio - Input:Output: 1:1 configuration
• Interface: On/Off control
• Voltage - Load: Maximum rating must equal or exceed 60V
• Current - Output: Minimum 1.4A capability
• Fault Protection: Current limiting and over-temperature protection required
• Operating Temperature Range: -40°C to 150°C (TJ)
• Mounting Type: Surface Mount
• Package Compatibility: TO-261-4 or TO-261AA

The substitute parts identified below meet these core electrical and mechanical requirements, enabling direct functional replacement in applications designed for the AUIPS2041LTR.

Engineering Selection Recommendations

BSP76E6433HUMA1 (Infineon Technologies, Active)

This part is an Infineon Technologies manufacturer-recommended substitute with active product status. It maintains the same 1:1 low-side N-Channel topology, 1.4A output current, and operating temperature range as the AUIPS2041LTR. The maximum load voltage is rated at 42V, which is lower than the original 60V specification. This part includes enhanced fault protection with over-voltage detection in addition to current limiting and over-temperature protection. ROHS3 compliance and identical package compatibility support direct board-level substitution where load voltage requirements do not exceed 42V.

BTS3110NHUMA1 (Infineon Technologies, Active)

This Infineon Technologies part is an active substitute with identical electrical specifications to the BSP76E6433HUMA1, including 1.4A output current, 42V maximum load voltage, and 1:1 switching ratio. It provides the same fault protection features and operating temperature range. The part is available in higher inventory quantities and maintains full package and compliance compatibility. Selection between this part and the BSP76E6433HUMA1 depends on application-specific load voltage requirements and availability constraints.

BSP75GTA (Diodes Incorporated, Active)

This part is manufactured by Diodes Incorporated and represents an alternative from a different supplier. It maintains the 1:1 low-side N-Channel configuration with 1.6A output current capability and 60V maximum load voltage, matching the original AUIPS2041LTR voltage rating. The Rds On specification is higher at 550mOhm compared to the original 100mOhm, which affects power dissipation characteristics. This part includes over-voltage protection and is ROHS3 compliant with unlimited moisture sensitivity level. Selection of this part is appropriate for applications requiring the full 60V load voltage capability where higher on-resistance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can BSP76E6433HUMA1 or BTS3110NHUMA1 be used in applications designed for 60V load voltage?

A: No. These parts are rated for a maximum load voltage of 42V. Applications requiring 60V operation must use BSP75GTA or confirm that actual load voltage requirements do not exceed 42V.

Q: What is the primary difference between BSP76E6433HUMA1 and BTS3110NHUMA1?

A: Both parts share identical electrical specifications, fault protection features, and package compatibility. The primary difference is inventory availability and potential supplier lead times. Selection between these two Infineon parts can be based on procurement requirements.

Q: Is BSP75GTA a direct replacement for AUIPS2041LTR?

A: BSP75GTA maintains the same 60V load voltage rating and 1:1 switching topology. However, the Rds On specification is significantly higher at 550mOhm versus the original 100mOhm. This affects power dissipation and thermal performance. Thermal analysis is required to confirm suitability in applications with high switching frequency or continuous current operation.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts—BSP76E6433HUMA1, BTS3110NHUMA1, and BSP75GTA—are ROHS3 compliant and maintain compatibility with environmental regulations.

Q: Do the substitute parts support the same package footprint?

A: Yes. All substitute parts use TO-261-4 or TO-261AA package configurations, enabling direct board-level replacement without PCB redesign.

Q: What additional fault protection do the substitute parts provide?

A: BSP76E6433HUMA1 and BTS3110NHUMA1 include over-voltage protection in addition to current limiting and over-temperature protection. BSP75GTA also includes over-voltage protection. The original AUIPS2041LTR provides current limiting and over-temperature protection only.
