MPQ8632HGL-10-P Equivalent & Substitute Parts

Part Overview

The MPQ8632HGL-10-P is a buck switching regulator IC from Monolithic Power Systems designed for step-down voltage conversion applications. It delivers 10A output current with adjustable positive output voltage ranging from 0.611V to 13V, operating from a 2.5V to 18V input supply. The device integrates a synchronous rectifier and operates across the industrial temperature range of -40°C to 125°C.

This part carries a "Not For New Designs" status, indicating it has been superseded in the manufacturer's product roadmap. Identifying equivalent substitute parts is necessary for design continuity, long-term availability assurance, and access to active product support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8632HGL-10-P is determined by strict equivalence across the following critical parameters:

• Function and topology (step-down buck converter)
• Output configuration (positive adjustable)
• Output voltage range (0.611V to 13V minimum and maximum)
• Output current capability (10A)
• Switching frequency range (200kHz ~ 1MHz)
• Synchronous rectifier integration
• Operating temperature range (-40°C to 125°C)
• RoHS3 compliance and MSL rating

The substitute part MPQ8632HGLE-10-Z maintains functional and electrical equivalence across all critical parameters. Differences in input voltage minimum specification (4.5V vs. 2.5V) and package configuration (16-PowerVFQFN vs. 13-VFQFN) represent the primary distinctions. The substitute part carries an "Active" product status, ensuring ongoing manufacturer support and availability.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632HGLE-10-Z is the manufacturer-recommended substitute for the MPQ8632HGL-10-P. Both devices maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent environmental and regulatory qualification.

The primary consideration for substitution is the input voltage minimum specification. The MPQ8632HGL-10-P supports operation down to 2.5V input, while the MPQ8632HGLE-10-Z requires a minimum of 4.5V. Applications operating below 4.5V input voltage cannot use the substitute part.

The package transition from 13-VFQFN to 16-PowerVFQFN requires PCB layout modification. The 16-PowerVFQFN package provides enhanced thermal performance through additional power pins, which may improve thermal management in high-current applications. Both packages maintain the same 3x4mm footprint dimensions.

The active product status of MPQ8632HGLE-10-Z provides assurance of continued manufacturer support, documentation updates, and long-term availability compared to the obsolete status of the original part.

Frequently Asked Questions (FAQ)

Q: Can MPQ8632HGLE-10-Z replace MPQ8632HGL-10-P in all applications?

A: Substitution is valid only for applications where the input voltage remains at or above 4.5V. The original part supports 2.5V minimum input; the substitute requires 4.5V minimum. All other electrical parameters are equivalent.

Q: What are the package differences between these parts?

A: The MPQ8632HGL-10-P uses a 13-pin VFQFN package, while the MPQ8632HGLE-10-Z uses a 16-pin PowerVFQFN package. Both maintain 3x4mm dimensions. The 16-pin variant includes additional power pins for improved thermal dissipation. PCB layout redesign is required for substitution.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity). Regulatory compliance is equivalent between the two devices.

Q: Why is the original part marked "Not For New Designs"?

A: This designation indicates the manufacturer has transitioned the product line. The MPQ8632HGLE-10-Z carries "Active" status and represents the current product offering for this functional category.

Q: What is the thermal advantage of the 16-PowerVFQFN package?

A: The 16-PowerVFQFN package includes additional power distribution pins compared to the 13-VFQFN, enabling lower thermal resistance and improved current distribution at maximum load conditions.
