MP62350EK-LF-Z Equivalent & Substitute Parts

Part Overview

The MP62350EK-LF-Z is a Power Switch/Driver IC from Monolithic Power Systems Inc., designed for 1:2 output configuration with 500mA maximum output current. This component operates across a 2.7V to 5.5V load voltage range and integrates load discharge, status flag monitoring, and comprehensive fault protection including current limiting, over-temperature, reverse current, and UVLO (Under-Voltage Lock-Out) functions.

The MP62350EK-LF-Z carries a "Not For New Designs" product status, making identification of active equivalent alternatives essential for ongoing production and new design implementations. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering current availability and active product support.

Substitute Part Grouping Explanation

Substitution eligibility for the MP62350EK-LF-Z is determined by strict equivalence across the following critical parameters:

• Switch Configuration: General Purpose, 1:2 output ratio, high-side configuration
• Electrical Performance: 500mA maximum output current, 85mOhm typical on-resistance, 2.7V to 5.5V load voltage range
• Protection Features: Current limiting, over-temperature protection, reverse current protection, and UVLO
• Interface & Control: Non-inverting on/off control with load discharge and status flag capabilities
• Thermal Range: -20°C to 85°C operating temperature
• Package Compatibility: 8-MSOP surface mount package with identical pinout and mechanical dimensions

The substitute parts MP62351EK-LF-P and MP62351EK-LF-Z meet all electrical and mechanical equivalence criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Both MP62351EK-LF-P and MP62351EK-LF-Z are direct parametric equivalents to the MP62350EK-LF-Z. Selection between these substitutes should be based on the following criteria:

Product Status: The MP62350EK-LF-Z carries "Not For New Designs" status. Both substitute parts maintain "Active" product status, ensuring long-term availability and manufacturer support for new production runs and design implementations.

Compliance & Certifications: All three parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance across applications.

Availability: The MP62351EK-LF-Z offers the highest current inventory (1055 Pcs), followed by MP62351EK-LF-P (980 Pcs), compared to the legacy MP62350EK-LF-Z (796 Pcs). For applications requiring immediate procurement or high-volume production, the MP62351EK-LF-Z variant provides superior supply chain assurance.

Packaging Designation: The MP62351EK-LF-P and MP62351EK-LF-Z differ only in packaging designation suffix. Both maintain identical electrical specifications and 8-MSOP mechanical compatibility. Selection between these variants depends on specific procurement and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can MP62351EK-LF-P and MP62351EK-LF-Z be used interchangeably with MP62350EK-LF-Z?

A: Yes. Both substitute parts maintain identical electrical parameters, including 500mA output current, 85mOhm on-resistance, 2.7V to 5.5V load voltage range, and all fault protection features. The 8-MSOP package pinout and mechanical dimensions are identical, enabling direct PCB-level substitution without circuit modification.

Q: What is the difference between MP62351EK-LF-P and MP62351EK-LF-Z?

A: Both parts are parametric equivalents with identical electrical specifications and package dimensions. The suffix designation (P vs. Z) indicates packaging or tape configuration differences. Consult the specific packaging documentation for your procurement requirements.

Q: Why is the MP62350EK-LF-Z marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status within the manufacturer's product portfolio. The MP62351 series represents the active replacement line, offering equivalent functionality with ongoing manufacturer support and improved long-term availability.

Q: Are there any thermal or environmental differences between these parts?

A: No. All three parts maintain identical operating temperature range (-20°C to 85°C), MSL 1 moisture sensitivity, ROHS3 compliance, and REACH status. Environmental and thermal performance characteristics are equivalent across all variants.

Q: What protection features are included in these power switch ICs?

A: All three parts integrate current limiting (fixed threshold), over-temperature protection, reverse current protection, and UVLO (Under-Voltage Lock-Out). These features operate identically across the MP62350EK-LF-Z and both MP62351 substitutes.

Q: Is the 8-MSOP package compatible with standard surface mount assembly processes?

A: Yes. The 8-MSOP package (0.118" width, 3.00mm) is a standard surface mount package compatible with conventional pick-and-place and reflow soldering processes. All three parts use identical package geometry and pinout.
