Substitute Part Grouping Explanation

Substitution of the MP8764GLE-Z is determined by strict equivalence across all electrical and mechanical parameters. The substitute parts MPQ8632GLE-12-Z and MPQ8632GLE-12-P maintain identical specifications in the following critical areas:

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

The primary distinction between substitute parts lies in product status and packaging designation. MPQ8632GLE-12-Z and MPQ8632GLE-12-P are both classified as "Active" products, whereas the original MP8764GLE-Z is "Not For New Designs."

Parameter Comparison

Frequently Asked Questions (FAQ)

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

A: Yes. All three parts share identical electrical specifications including input voltage range (4.5V to 18V), output voltage range (0.611V to 13V), output current (12A), switching frequency (200kHz to 1MHz), and package configuration (16-PowerVFQFN). Pin-for-pin compatibility is maintained across all three part numbers.

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

A: Both parts are electrically and mechanically identical. The difference is in the packaging designation suffix. Both are supplied in Tape & Reel format and carry "Active" product status. Selection should be based on inventory availability and supply chain logistics.

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

A: This designation indicates the part is in mature or end-of-life phase. For new designs, MPQ8632GLE-12-Z or MPQ8632GLE-12-P are recommended as they maintain identical specifications while offering active product status and assured long-term availability.

Q: Are there any thermal or performance differences between these parts?

A: No. All three parts operate across the same temperature range (-40°C to 125°C) and maintain identical thermal characteristics. Synchronous rectifier functionality and switching frequency ranges are identical.

Q: Do these parts require different PCB layouts or design considerations?

A: No. The 16-PowerVFQFN (3x4) package is identical across all three parts. PCB layouts, thermal management strategies, and component placement remain unchanged during substitution.
