Substitute Part Grouping Explanation

Substitution of the MP8764GLE-P is determined by strict equivalence across the following critical parameters:

• Input voltage range: 4.5V to 18V
• Output voltage adjustability: 0.611V to 13V
• Output current capacity: 12A
• Switching frequency: 200kHz to 1MHz
• Synchronous rectification capability
• Package type: 16-PowerVFQFN (3x4)
• Operating temperature range: -40°C to 125°C
• Surface mount configuration
• RoHS3 compliance and MSL rating

The identified substitutes—MPQ8632GLE-12-P and MPQ8632GLE-12-Z—maintain identical electrical specifications and mechanical compatibility with the original MP8764GLE-P. Both substitute parts are manufactured by Monolithic Power Systems Inc. and share the same functional topology, output characteristics, and thermal operating range.

Parameter Comparison

Engineering Selection Recommendations

The MP8764GLE-P is designated "Not For New Designs," indicating that Monolithic Power Systems Inc. has discontinued active support for this part number. Both substitute parts—MPQ8632GLE-12-P and MPQ8632GLE-12-Z—carry "Active" product status, ensuring ongoing manufacturer support, availability, and compliance maintenance.

MPQ8632GLE-12-P is supplied in Tape & Reel (TR) packaging with 2000 pieces currently in stock. This variant is suitable for production environments requiring standard packaging formats.

MPQ8632GLE-12-Z is available in higher inventory (9611 pieces) and represents the preferred alternative for applications where packaging flexibility is acceptable. Both parts maintain identical electrical and thermal specifications, differing only in packaging designation and current stock levels.

Selection between the two active substitutes should be based on packaging requirements and supply chain availability rather than functional or electrical considerations.

Frequently Asked Questions (FAQ)

Q: Can MPQ8632GLE-12-P and MPQ8632GLE-12-Z be used interchangeably with MP8764GLE-P?

A: Yes. Both substitute parts maintain identical electrical specifications, output characteristics, switching frequency range, and thermal operating parameters. The 16-PowerVFQFN package footprint is identical across all three part numbers, enabling direct PCB-level substitution without design modification.

Q: What is the difference between MPQ8632GLE-12-P and MPQ8632GLE-12-Z?

A: The primary difference is packaging designation. MPQ8632GLE-12-P is supplied in Tape & Reel (TR) format, while MPQ8632GLE-12-Z packaging is not specified in the provided data. Both parts are electrically and mechanically identical. Selection should be based on procurement and assembly process requirements.

Q: Why is MP8764GLE-P marked "Not For New Designs"?

A: This designation indicates that Monolithic Power Systems Inc. has transitioned this part to end-of-life status and is no longer recommending it for new product development. The active substitutes (MPQ8632GLE-12-P and MPQ8632GLE-12-Z) provide equivalent functionality with ongoing manufacturer support.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and share identical REACH and ECCN classifications. Compliance status is equivalent across all variants.

Q: What is the 16-PowerVFQFN package specification?

A: The 16-PowerVFQFN is a 16-pin quad flat no-lead package with 3mm × 4mm footprint dimensions. This surface mount package is identical across MP8764GLE-P, MPQ8632GLE-12-P, and MPQ8632GLE-12-Z, ensuring mechanical compatibility without PCB redesign.

Q: Can I use these substitutes in existing inventory or legacy designs?

A: Yes. The electrical and mechanical equivalence of these parts allows direct substitution in existing designs without circuit modification or PCB layout changes. The identical package footprint and pin configuration ensure compatibility with existing assembly processes.
