Engineering Selection Recommendations

The MP8763GLE-Z is designated as Not For New Designs. For new applications requiring a 12A buck regulator with the specified electrical and thermal characteristics, the MPQ8632GLE-12-Z and MPQ8632GLE-12-P are active product alternatives from Monolithic Power Systems Inc.

Both substitute parts maintain full electrical and mechanical compatibility with the MP8763GLE-Z:

• MPQ8632GLE-12-Z: Active product status with 9,611 units in stock. Packaging designation indicates tape and reel availability. Suitable for production environments requiring high-volume component sourcing.

• MPQ8632GLE-12-P: Active product status with 2,000 units in stock. Packaging designation indicates tape and reel availability. Suitable for applications where component availability and active product support are required.

Both alternatives carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity ratings, ensuring regulatory and environmental compliance equivalence with the original part.

Frequently Asked Questions (FAQ)

Q: Can MPQ8632GLE-12-Z or MPQ8632GLE-12-P be used as direct replacements for MP8763GLE-Z?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, output current rating (12A), input voltage range (4.5V to 18V), adjustable output range (0.611V to 13V), switching frequency (200kHz to 1MHz), and 16-PowerVFQFN package configuration. PCB layout and schematic compatibility is maintained.

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

A: Both parts are electrically identical. The suffix designation (-Z vs -P) indicates packaging or tape configuration differences. Verify packaging requirements with your supply chain before selection.

Q: Why is MP8763GLE-Z marked as Not For New Designs?

A: This designation indicates the part is in mature or end-of-life status. Monolithic Power Systems Inc. recommends using active alternatives (MPQ8632GLE-12-Z or MPQ8632GLE-12-P) for new designs to ensure long-term availability and continued manufacturer support.

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

A: No. All three parts operate across the identical temperature range (-40°C to 125°C junction temperature) and deliver the same 12A output current with synchronous rectification enabled.

Q: Do these parts require different PCB layout considerations?

A: No. All parts use the 16-PowerVFQFN (3x4) surface mount package. PCB footprint, thermal pad design, and layout guidelines remain consistent across all three part numbers.

Q: Are compliance certifications identical across all three parts?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, carry MSL 1 moisture sensitivity rating, and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.
