Substitute Part Grouping Explanation

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

• Electrical Performance: Number of outputs (2), input-to-output ratio (1:2), output configuration (High Side), maximum output current (500mA), and on-resistance (85mOhm typical)
• Voltage Specifications: Load voltage range (2.7V ~ 5.5V) and input type (Non-Inverting)
• Protection Features: Current limiting, over-temperature protection, reverse current protection, and UVLO functionality
• Thermal Range: Operating temperature range (-20°C ~ 85°C)
• Package Compatibility: 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Compliance Standards: ROHS3 compliance and MSL rating (2, 1 Year)

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

Parameter Comparison

Engineering Selection Recommendations

The MP62351ES-LF-Z is a direct parametric equivalent to the MP62350ES-LF-Z. Both components share identical electrical specifications, package geometry, and compliance certifications.

For applications currently using the MP62350ES-LF-Z, the MP62351ES-LF-Z provides equivalent functionality with the advantage of ongoing manufacturer support and availability. Both parts are ROHS3 compliant and carry identical MSL ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the MP62351ES-LF-Z be used as a direct replacement for the MP62350ES-LF-Z?

A: Yes. The MP62351ES-LF-Z is a parametric equivalent with identical electrical performance, output current rating, on-resistance, protection features, operating temperature range, and 8-SOIC package specifications. No circuit modifications are required.

Q: What is the significance of the "Not For New Designs" status on the MP62350ES-LF-Z?

A: This designation indicates the manufacturer is not recommending the part for new product development. The MP62351ES-LF-Z, with "Active" status, is the recommended alternative for ongoing and future applications.

Q: Are there any differences in package dimensions between these parts?

A: No. Both the MP62350ES-LF-Z and MP62351ES-LF-Z use the 8-SOIC package with identical physical dimensions (0.154", 3.90mm Width), ensuring PCB layout compatibility.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both components are ROHS3 compliant with MSL rating 2 (1 Year), meeting identical regulatory and moisture sensitivity requirements.

Q: What are the key electrical parameters that define substitution eligibility?

A: Substitution is based on matching the number of outputs (2), input-to-output ratio (1:2), maximum output current (500mA), on-resistance (85mOhm), load voltage range (2.7V ~ 5.5V), fault protection features (current limiting, over-temperature, reverse current, UVLO), and operating temperature range (-20°C ~ 85°C).
