MPQ8632HGLE-10-Z Equivalent & Substitute Parts

Part Overview

The MPQ8632HGLE-10-Z is an active buck switching regulator IC manufactured by Monolithic Power Systems Inc., designed for positive adjustable output applications. This Power Management IC operates as a step-down converter with a maximum output current of 10A and adjustable output voltage ranging from 0.611V to 13V. The device is housed in a 16-PowerVFQFN surface mount package and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Finding equivalent and substitute parts becomes necessary when the primary part number is unavailable, when inventory constraints require alternative sourcing, or when application requirements allow for compatible variants with enhanced specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8632HGLE-10-Z is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Identical base product number (MPQ8632 series)
• Matching input voltage range (4.5V to 18V)
• Matching output voltage range (0.611V to 13V)
• Identical package type (16-PowerVFQFN)
• Identical mounting type (Surface Mount)
• Matching topology (Buck converter with synchronous rectifier)
• Compatible operating temperature range (-40°C to 125°C)

Allowable Variation:

• Output current rating may be equal to or greater than the main part specification (10A minimum)
• Switching frequency range must encompass or match the specified range (200kHz to 1MHz)

The MPQ8632GLE-12-P qualifies as a direct substitute based on these criteria, with the primary distinction being an increased output current rating of 12A compared to the main part's 10A specification.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GLE-12-P is a qualified substitute for the MPQ8632HGLE-10-Z based on electrical and mechanical parameter alignment. Both devices maintain active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

The primary technical distinction is the increased output current capability of the MPQ8632GLE-12-P (12A versus 10A). This higher current rating does not introduce incompatibility; rather, it provides additional design margin for applications requiring the full 10A specification of the original part. The substitute part will operate within identical electrical parameters and thermal specifications.

Packaging format differs between the two parts: the main part is supplied in bulk format, while the substitute is available in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MPQ8632GLE-12-P directly replace the MPQ8632HGLE-10-Z in existing designs?

A: Yes. Both parts share identical electrical specifications for input voltage range, output voltage range, switching frequency, and operating temperature. The 16-PowerVFQFN package and surface mount configuration are identical, enabling direct PCB-level substitution without layout modifications.

Q: What is the significance of the higher 12A current rating in the substitute part?

A: The MPQ8632GLE-12-P is rated for 12A maximum output current, compared to 10A for the main part. This higher rating provides additional thermal and electrical margin. Applications designed for 10A operation will function within the substitute's specifications without stress or derating.

Q: Are there differences in packaging that affect assembly?

A: The main part (MPQ8632HGLE-10-Z) is supplied in bulk format, while the substitute (MPQ8632GLE-12-P) is supplied in Tape & Reel (TR) format. This affects procurement and automated assembly processes but does not impact the component's electrical performance or PCB mounting.

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

A: Yes. Both the MPQ8632HGLE-10-Z and MPQ8632GLE-12-P are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Regulatory and environmental compliance requirements are satisfied by either part.

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

A: No. Both parts operate across the identical temperature range (-40°C to 125°C junction temperature) and share the same moisture sensitivity level (MSL 1, unlimited). Thermal performance and long-term reliability characteristics are equivalent.
