MPQ8636GLE-10-Z Equivalent & Substitute Parts

Part Overview

The MPQ8636GLE-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 delivers 10A output current with an adjustable voltage 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 maintained across the specified parameter ranges, enabling seamless integration into existing designs or procurement scenarios.

Key Parameters

Substitute Part Grouping Explanation

The MPQ8632GLE-12-P qualifies as a direct substitute based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Identical input voltage range (4.5V to 18V)
• Identical output voltage range (0.611V to 13V)
• Identical output configuration (Positive Adjustable)
• Identical switching frequency range (200kHz to 1MHz)
• Identical synchronous rectifier implementation
• Identical operating temperature range (-40°C to 125°C)
• Identical package type (16-PowerVFQFN, 3x4)
• Identical mounting type (Surface Mount)
• Identical RoHS and MSL compliance

Distinguishing Parameter:

• Output current: MPQ8636GLE-10-Z provides 10A; MPQ8632GLE-12-P provides 12A

The higher current rating of the substitute part (12A vs. 10A) maintains full backward compatibility while providing additional current headroom for applications requiring higher load capacity.

Parameter Comparison

Engineering Selection Recommendations

Both the MPQ8636GLE-10-Z and MPQ8632GLE-12-P are active products from Monolithic Power Systems Inc. with identical regulatory compliance profiles. The MPQ8632GLE-12-P offers increased output current capacity (12A versus 10A) while maintaining all electrical specifications and mechanical compatibility.

Selection between these parts depends on application current requirements. The MPQ8636GLE-10-Z is appropriate for designs requiring up to 10A output. The MPQ8632GLE-12-P accommodates applications requiring up to 12A output and provides additional thermal margin in current-limited designs. Both parts maintain identical input/output voltage ranges, switching frequency characteristics, and thermal operating specifications.

Frequently Asked Questions (FAQ)

Q: Can MPQ8632GLE-12-P replace MPQ8636GLE-10-Z in existing designs?

A: Yes. The MPQ8632GLE-12-P maintains identical electrical specifications across input voltage range (4.5V to 18V), output voltage range (0.611V to 13V), switching frequency (200kHz to 1MHz), and operating temperature range (-40°C to 125°C). The package footprint (16-PowerVFQFN, 3x4) and pin configuration are identical. The higher current rating (12A vs. 10A) provides additional capacity without affecting compatibility.

Q: Are there package or mounting differences between these parts?

A: No. Both parts use identical 16-PowerVFQFN surface mount packages with 3x4mm dimensions. PCB layout and assembly processes remain unchanged.

Q: Do these parts have different compliance certifications?

A: No. Both parts carry identical ROHS3 compliance, MSL rating of 1 (Unlimited), REACH Unaffected status, and EAR99 ECCN classification.

Q: What is the primary difference between these two parts?

A: The output current specification is the distinguishing parameter. MPQ8636GLE-10-Z delivers 10A maximum output current, while MPQ8632GLE-12-P delivers 12A maximum output current. All other electrical and mechanical parameters are identical.

Q: Which part should be selected for new designs?

A: Selection is based on application current requirements. For designs requiring up to 10A, either part is suitable. For designs requiring 10A to 12A output, the MPQ8632GLE-12-P is required. Both parts are active products with equivalent availability and lead times.
