MPQ8632GL-10-P Equivalent & Substitute Parts

Part Overview

The MPQ8632GL-10-P is a buck switching regulator IC manufactured by Monolithic Power Systems Inc., designed for step-down voltage conversion with positive adjustable output. This device delivers 10A output current across an input voltage range of 2.5V to 18V, with adjustable output voltage from 0.611V to 13V. The part is marked as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent or substitute parts is necessary for ongoing production support, maintenance applications, and legacy system repairs where this topology and performance specification remain required.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MPQ8632GL-10-P is determined by the following critical parameters:

• Output current capability: 10A
• Output voltage adjustability: 0.611V to 13V range
• Input voltage range: Minimum 2.5V to maximum 18V
• Switching frequency: 200kHz to 1MHz
• Synchronous rectifier topology: Required
• Operating temperature range: -40°C to 125°C
• Surface mount packaging with QFN form factor
• ROHS3 compliance and MSL Level 1

The substitute part MP8762GLE-P meets these core functional requirements with the following distinction: the minimum input voltage is 4.5V rather than 2.5V. This represents a narrower input voltage specification but maintains all other critical parameters including output current, adjustable output voltage range, switching frequency, synchronous rectification, temperature range, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MP8762GLE-P serves as a functional substitute for the MPQ8632GL-10-P in applications where the minimum input voltage requirement of 4.5V is acceptable. Both devices maintain ROHS3 compliance and MSL Level 1 rating, ensuring equivalent environmental and regulatory standing. The primary design consideration is the input voltage floor: applications requiring operation below 4.5V input must retain the original MPQ8632GL-10-P. The package change from 13-VFQFN to 16-PowerVFQFN requires PCB layout modification but does not affect electrical performance or thermal characteristics within the specified operating range. Both parts are marked "Not For New Designs," indicating they are suitable for legacy system support and production continuity only.

Frequently Asked Questions (FAQ)

Q: Can MP8762GLE-P replace MPQ8632GL-10-P in all applications?

A: Substitution is valid only when the application input voltage remains at or above 4.5V. The MPQ8632GL-10-P supports input voltages as low as 2.5V; the MP8762GLE-P does not. All other electrical specifications are equivalent.

Q: What is the impact of the package change from 13-VFQFN to 16-PowerVFQFN?

A: The package change requires PCB layout redesign. The 16-PowerVFQFN package has different pin assignments and thermal pad configuration. Schematic connections remain functionally identical, but board-level routing and thermal management design must be updated accordingly.

Q: Are both parts suitable for new product designs?

A: No. Both the MPQ8632GL-10-P and MP8762GLE-P are marked "Not For New Designs." These parts are appropriate for legacy system maintenance, production continuity, and repair applications only.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant with MSL Level 1 rating, REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: What is the inventory status for these parts?

A: MPQ8632GL-10-P has 1180 pieces in stock. MP8762GLE-P has 3498 pieces in stock. Both are listed as new original inventory.
