Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8636HGL-10-P is determined by the following critical parameters:

• Input voltage range: 4.5V to 18V minimum requirement
• Output topology: Buck (step-down) configuration with positive output
• Synchronous rectification capability
• Package compatibility: 13-VFQFN form factor
• Operating temperature range: -40°C to 125°C
• Surface mount mounting type
• RoHS3 compliance

The UCD74106RGMR from Texas Instruments qualifies as a substitute based on matching input voltage specifications, buck topology, synchronous rectification, identical package form factor, temperature range, and RoHS3 compliance. However, output current capability differs between the two devices, requiring circuit-level evaluation for applications demanding the full 10A specification of the original part.

Parameter Comparison

Engineering Selection Recommendations

The UCD74106RGMR is suitable as a substitute for the MPQ8636HGL-10-P in applications where the 6A output current specification meets system requirements. Both devices maintain identical input voltage operating ranges, temperature specifications, and RoHS3 compliance status. The UCD74106RGMR carries Active product status, providing long-term availability and design support advantages over the Not For New Designs classification of the original part.

Physical package dimensions differ between the two devices (3x4mm versus 3x3mm), requiring PCB layout verification prior to implementation. The higher switching frequency capability of the UCD74106RGMR (up to 2MHz versus 200kHz-1MHz) may provide improved transient response and reduced output filtering requirements in certain applications.

Frequently Asked Questions (FAQ)

Q: Can the UCD74106RGMR directly replace the MPQ8636HGL-10-P in existing designs?

A: Direct replacement requires verification that the application load current does not exceed 6A. The UCD74106RGMR output current rating is 4A lower than the original part. PCB layout modifications may be necessary due to package dimension differences (3x3mm versus 3x4mm).

Q: Are the output voltage ranges compatible between these devices?

A: The MPQ8636HGL-10-P specifies adjustable output from 0.611V to 13V. The UCD74106RGMR does not specify output voltage range in the provided parameters. Output voltage compatibility must be verified against specific application requirements and device datasheets.

Q: What are the package compatibility considerations?

A: Both devices use 13-VFQFN packages but with different footprint dimensions. The MPQ8636HGL-10-P uses a 3x4mm package while the UCD74106RGMR uses a 3x3mm package. PCB redesign is required for physical compatibility.

Q: How do the switching frequency ranges affect circuit design?

A: The MPQ8636HGL-10-P operates at 200kHz to 1MHz, while the UCD74106RGMR operates up to 2MHz. Higher switching frequency in the UCD74106RGMR may reduce output filter component sizes but requires verification of EMI performance in the target application.

Q: Are both devices suitable for long-term production use?

A: The UCD74106RGMR carries Active product status, ensuring continued availability and manufacturer support. The MPQ8636HGL-10-P is classified as Not For New Designs, making the UCD74106RGMR preferable for ongoing production requirements.
