MPQ8636GL-10-P Equivalent & Substitute Parts

Part Overview

The MPQ8636GL-10-P is a buck switching regulator IC from Monolithic Power Systems Inc., designed for step-down voltage conversion with positive adjustable output. It delivers 10A output current across an input voltage range of 4.5V to 18V, with adjustable output from 0.611V to 13V. The device features synchronous rectification and operates across -40°C to 125°C. However, this part carries a "Not For New Designs" status, making identification of equivalent alternatives necessary for ongoing production and new design initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8636GL-10-P is determined by the following critical parameters:

• Input voltage range compatibility: 4.5V to 18V minimum requirement
• Output configuration: Positive adjustable topology
• Synchronous rectification capability
• Operating temperature range: -40°C to 125°C
• Package form factor: 13-VFQFN or compatible surface mount alternatives
• RoHS3 compliance

The UCD74106RGMR from Texas Instruments qualifies as a substitute based on matching input voltage range (4.5V to 18V), positive output configuration, single output topology, synchronous rectification, identical operating temperature range, compatible 13-VFQFN package, and ROHS3 compliance. However, output current capability differs at 6A versus the original 10A specification.

Parameter Comparison

Engineering Selection Recommendations

The UCD74106RGMR is an active product from Texas Instruments with ROHS3 compliance, making it suitable for new design implementations where the MPQ8636GL-10-P is restricted. Both devices share identical input voltage specifications, operating temperature range, and package footprint compatibility. The primary design consideration is output current capacity: the UCD74106RGMR delivers 6A maximum output current compared to the MPQ8636GL-10-P's 10A specification. Applications requiring the full 10A output capability of the original part cannot use this substitute without circuit redesign or parallel configuration evaluation. The UCD74106RGMR's higher switching frequency capability (up to 2MHz versus 200kHz ~ 1MHz) may provide advantages in component size optimization and thermal performance for lower current applications.

Frequently Asked Questions (FAQ)

Q: Can the UCD74106RGMR directly replace the MPQ8636GL-10-P in existing designs?

A: Direct replacement is possible only if the application's output current requirement does not exceed 6A. The UCD74106RGMR is rated for 6A maximum output, while the MPQ8636GL-10-P is rated for 10A. Designs requiring the full 10A capability require alternative solutions.

Q: Are the package footprints compatible between these two parts?

A: Both parts use 13-VFQFN packages suitable for surface mount assembly. The UCD74106RGMR includes an exposed pad variant. PCB layout compatibility should be verified with specific package drawings, as minor dimensional variations may exist between manufacturers.

Q: What is the impact of the different switching frequency ranges?

A: The MPQ8636GL-10-P operates at 200kHz to 1MHz, while the UCD74106RGMR operates up to 2MHz. Higher switching frequency reduces output filter component size but may increase switching losses. Frequency selection depends on application requirements for noise, efficiency, and component integration.

Q: Are both parts compliant with current regulatory requirements?

A: Both the MPQ8636GL-10-P and UCD74106RGMR are ROHS3 compliant. The UCD74106RGMR carries "Active" product status, indicating ongoing manufacturer support and availability for new designs. The MPQ8636GL-10-P's "Not For New Designs" status indicates it is in end-of-life phase.

Q: What are the output voltage specifications for each part?

A: The MPQ8636GL-10-P provides adjustable output from 0.611V to 13V. The UCD74106RGMR output voltage specifications are not provided in the available technical parameters and must be confirmed through the manufacturer's datasheet for specific application requirements.
