Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP62350ES-LF is determined by strict equivalence across the following critical parameters:

• Switch Configuration: 1:2 ratio with 2 outputs in high-side configuration
• Electrical Performance: 500mA maximum output current, 85mOhm typical on-resistance, 2.7V ~ 5.5V load voltage range
• Protection Features: Current limiting, over-temperature protection, reverse current protection, and UVLO
• Package Specification: 8-SOIC surface mount package with identical 0.154" (3.90mm) width
• Compliance Standards: ROHS3 compliance and MSL 2 rating
• Interface Type: Non-inverting on/off control with status flag output

The MP62351ES-LF meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the MP62350ES-LF and MP62351ES-LF are active production components from Monolithic Power Systems Inc. with identical electrical specifications, package geometry, and compliance certifications. Selection between these parts should be based on inventory availability and procurement lead times, as they are parametric equivalents with no functional differentiation.

The MP62351ES-LF currently maintains higher inventory levels (2160 units) compared to the MP62350ES-LF (921 units), which may influence supply chain decisions. Both parts carry ROHS3 compliance and identical MSL 2 ratings, ensuring equivalent reliability and handling requirements in manufacturing environments.
