Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8632GL-8-P is determined by the following critical parameters:

• Topology & Function: Buck switching regulator with step-down conversion capability
• Output Characteristics: Positive adjustable output voltage (0.611V to 13V minimum range)
• Current Capacity: Minimum 8A output current rating
• Input Voltage Compatibility: Overlapping input voltage range with the original specification
• Switching Frequency: Compatible frequency range (200kHz to 1MHz)
• Synchronous Rectification: Presence of integrated synchronous rectifier
• Thermal Performance: Operating temperature range of -40°C to 125°C
• Compliance: ROHS3 compliance and MSL rating compatibility

The substitute part MP8762GLE-P meets these criteria with enhanced specifications in output current (10A) and maintains full compatibility with the core functional requirements of the MPQ8632GL-8-P.

Parameter Comparison

Engineering Selection Recommendations

The MP8762GLE-P serves as a direct functional substitute for the MPQ8632GL-8-P. Both devices are manufactured by Monolithic Power Systems Inc. and maintain identical ROHS3 compliance and MSL ratings. The substitute part provides enhanced output current capacity (10A versus 8A), making it suitable for applications requiring equal or greater current delivery.

The primary design consideration is the minimum input voltage specification: the MP8762GLE-P requires a minimum of 4.5V input, compared to 2.5V for the original part. Applications operating below 4.5V input voltage cannot use the MP8762GLE-P as a substitute. Both parts share identical package footprint dimensions (3x4mm) but differ in pin count and package designation (13-VFQFN versus 16-PowerVFQFN), requiring PCB layout verification before implementation.

Both parts carry "Not For New Designs" status, indicating end-of-life classification. For new design initiatives, consultation with Monolithic Power Systems Inc. for current-generation alternatives is recommended.

Frequently Asked Questions (FAQ)

Q: Can the MP8762GLE-P replace the MPQ8632GL-8-P in all applications?

A: The MP8762GLE-P is functionally compatible for applications where the input voltage remains at or above 4.5V. The original MPQ8632GL-8-P supports input voltages as low as 2.5V. If your application requires operation below 4.5V input, the MP8762GLE-P is not suitable. Additionally, the package change from 13-pin to 16-pin requires PCB layout modification.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) output current rating (8A versus 10A), (2) minimum input voltage (2.5V versus 4.5V), and (3) package configuration (13-VFQFN versus 16-PowerVFQFN). All other functional parameters, including output voltage range, switching frequency, and thermal specifications, remain identical.

Q: Are there pin-to-pin compatibility considerations?

A: No. The package change from 13-VFQFN to 16-PowerVFQFN means these parts are not pin-compatible. PCB redesign is required to accommodate the different pin count and layout.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the MPQ8632GL-8-P and MP8762GLE-P are ROHS3 compliant with MSL rating 1 (Unlimited), REACH unaffected status, and identical ECCN and HTSUS classifications.

Q: Why is the MPQ8632GL-8-P marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. Monolithic Power Systems Inc. no longer recommends this part for new product development. Existing inventory remains available for production support and maintenance applications.
