Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8632DGLE-6-P is determined by the following critical parameters:

• Input voltage range: 4.5V to 18V minimum
• Output voltage adjustability: 0.611V to 13V minimum
• Package type: 16-PowerVFQFN (3x4) surface mount
• Topology: Buck switching regulator with synchronous rectification
• Operating temperature range: -40°C to 125°C (TJ)
• Compliance: ROHS3, MSL 1

The substitute part MP8761GLE-P maintains all critical electrical and mechanical parameters while offering increased output current capacity of 8A compared to the 6A rating of the primary part. Both devices share identical input/output voltage specifications, switching frequency range, package configuration, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The MP8761GLE-P serves as a direct substitute for the MPQ8632DGLE-6-P in applications requiring equivalent or higher current delivery. Both parts maintain identical electrical specifications for input voltage, output voltage range, switching frequency, and thermal operating conditions. The package footprint and pinout compatibility enable direct board-level substitution.

The primary distinction is the increased current rating of 8A on the MP8761GLE-P versus 6A on the MPQ8632DGLE-6-P. This higher current capacity makes the MP8761GLE-P suitable for designs with increased power delivery requirements while maintaining full compatibility with existing circuit topologies.

Product status consideration: The MP8761GLE-P carries a "Not For New Designs" designation, indicating it is suitable for legacy system support and replacement applications but not recommended for new product development. The MPQ8632DGLE-6-P maintains active status and is the preferred choice for new designs within its 6A current specification.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring equivalent environmental and regulatory compatibility.

Frequently Asked Questions (FAQ)

Q: Can MP8761GLE-P replace MPQ8632DGLE-6-P in existing designs?

A: Yes. Both devices share identical input voltage range (4.5V to 18V), output voltage adjustability (0.611V to 13V), switching frequency (200kHz to 1MHz), package configuration (16-PowerVFQFN 3x4), and operating temperature range (-40°C to 125°C). The MP8761GLE-P provides higher current capacity (8A vs 6A) and is electrically and mechanically compatible.

Q: What is the primary difference between these parts?

A: The output current rating differs: MPQ8632DGLE-6-P delivers 6A maximum, while MP8761GLE-P delivers 8A maximum. All other electrical and mechanical specifications remain identical.

Q: Are there package compatibility concerns?

A: No. Both parts use the 16-PowerVFQFN (3x4) surface mount package with identical pinout and footprint, enabling direct board-level substitution without layout modifications.

Q: Does product status affect substitution suitability?

A: Product status reflects manufacturing and design recommendations. The MP8761GLE-P is designated "Not For New Designs," making it appropriate for replacement and legacy support applications. For new product development, the active-status MPQ8632DGLE-6-P is the recommended choice.

Q: Are compliance certifications equivalent?

A: Yes. Both parts maintain ROHS3 compliance, MSL 1 rating (unlimited moisture sensitivity), and identical regulatory certifications, ensuring equivalent environmental and compliance compatibility.

Q: What inventory considerations apply?

A: The MPQ8632DGLE-6-P has 713 units in stock (active status), while MP8761GLE-P has 1302 units available (legacy status). Inventory availability may influence substitution decisions based on project timelines.
