MPQ8632GLE-10-Z Equivalent & Substitute Parts

Part Overview

The MPQ8632GLE-10-Z is an active buck switching regulator IC from Monolithic Power Systems Inc., designed for positive adjustable output voltage regulation. This Power Management IC delivers 10A output current with an adjustable output range from 0.611V to 13V, operating from a 4.5V to 18V input supply. The device is housed in a 16-PowerVFQFN surface mount package and is ROHS3 compliant with unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application scaling, or design optimization needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8632GLE-10-Z is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Manufacturer: Monolithic Power Systems Inc.
• Base Product Number: MPQ8632
• Package Type: 16-PowerVFQFN (3x4)
• Input Voltage Range: 4.5V to 18V
• Output Voltage Range: 0.611V to 13V
• Switching Frequency: 200kHz to 1MHz
• Synchronous Rectifier: Yes
• Operating Temperature: -40°C to 125°C (TJ)
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Variable Parameter Allowing Substitution:

• Output Current: The MPQ8632GLE-10-Z (10A) can be substituted with the MPQ8632GLE-12-P (12A). The higher current rating of the substitute part maintains full compatibility with all electrical and thermal specifications while providing increased current delivery capability.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GLE-12-P is a valid substitute for the MPQ8632GLE-10-Z based on the following engineering criteria:

Electrical Compatibility: Both devices share identical input voltage range (4.5V to 18V), output voltage range (0.611V to 13V), switching frequency (200kHz to 1MHz), and thermal operating range (-40°C to 125°C). The substitute part's 12A output current rating exceeds the original 10A specification, providing additional current delivery margin without compromising any electrical parameter.

Mechanical Compatibility: Both parts use the identical 16-PowerVFQFN (3x4) surface mount package, ensuring PCB layout and thermal management compatibility.

Compliance & Certification: Both parts maintain ROHS3 compliance, EAR99 ECCN classification, and MSL Level 1 (Unlimited) moisture sensitivity rating, meeting all regulatory and environmental requirements.

Packaging Consideration: The original part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the MPQ8632GLE-12-P directly replace the MPQ8632GLE-10-Z in my design?

A: Yes. The MPQ8632GLE-12-P is electrically and mechanically compatible with the MPQ8632GLE-10-Z. Both devices share identical input/output voltage ranges, switching frequency, package type, and thermal specifications. The substitute part's higher 12A current rating is a superset of the original 10A specification.

Q: What is the difference between the two part numbers?

A: The primary difference is the output current rating: MPQ8632GLE-10-Z delivers 10A, while MPQ8632GLE-12-P delivers 12A. Both parts are from the same MPQ8632 product family and share all other electrical and mechanical characteristics.

Q: Are there any thermal or reliability concerns when using the higher-rated substitute?

A: No. Both parts operate within the same temperature range (-40°C to 125°C) and share identical thermal management characteristics. The higher current rating of the substitute part does not introduce additional thermal stress when operating within the original design's current requirements.

Q: Does the packaging format difference affect compatibility?

A: The packaging format difference (bulk versus Tape & Reel) affects supply chain handling and assembly processes but does not impact electrical performance or PCB compatibility. Both parts use the identical 16-PowerVFQFN (3x4) surface mount package.

Q: Are both parts currently in production?

A: Yes. Both the MPQ8632GLE-10-Z and MPQ8632GLE-12-P maintain Active product status with Monolithic Power Systems Inc.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, carry EAR99 ECCN classification, and maintain MSL Level 1 (Unlimited) moisture sensitivity rating.
