Key Parameters

Substitute Part Grouping Explanation

Substitution of the AP2141AW-7 is determined by strict equivalence across the following critical parameters:

• Switch Type & Output Configuration: USB Switch with P-Channel high-side output
• Electrical Performance: 500mA maximum output current, 95mOhm typical on-resistance
• Voltage Range: 2.7V to 5.5V load voltage compatibility
• Input/Output Ratio: 1:1 configuration with non-inverting input
• Protection Features: Current limiting, over-temperature, reverse current, and UVLO protection
• Package Compatibility: SOT-25 (SC-74A, SOT-753) surface mount package
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The AP2151AW-7 meets all these criteria and is designated as the manufacturer-recommended substitute, offering identical electrical specifications and package footprint with active product status.

Parameter Comparison
