Key Parameters

Substitute Part Grouping Explanation

Substitution for the PI5PD2041BTAEX is determined by the following critical parameters:

• Package Compatibility: SOT-23-5 (SC-74A, SOT-753) pinout and physical dimensions
• Functional Category: Power Management IC with switching or supervisory control capability
• Electrical Interface: Single-channel output with compatible voltage and current ratings
• Operating Voltage Range: Support for 2.7V to 5.5V load voltage operation
• Fault Protection: Integrated protection mechanisms (current limiting, over-temperature, reverse current, UVLO)
• Compliance Standards: RoHS3 compliance and MSL Level 1 rating
• Temperature Range: Operating specifications within -40°C to 85°C minimum

The substitute part TPS3836L30QDBVRQ1 from Texas Instruments meets these criteria through identical SOT-23-5 packaging, compatible voltage monitoring threshold, integrated protection features, and superior product status (Active vs. Obsolete).
