Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP8761GLE-Z is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Input voltage range: 4.5V to 18V
• Output voltage adjustability: 0.611V to 13V
• Switching frequency: 200kHz to 1MHz
• Synchronous rectifier topology
• Operating temperature: -40°C to 125°C

Mechanical Compatibility Criteria:

• Package type: 16-PowerVFQFN (16-QFN 3x4)
• Surface mount mounting type
• Moisture sensitivity level: 1 (Unlimited)

Identified Substitute Parts:

1. MP8761GLE-P – Direct electrical equivalent with identical specifications; differs only in packaging format (Cut Tape vs. original)
2. MPQ8632GLE-12-Z – Higher current rating (12A vs. 8A); maintains all voltage, frequency, and thermal specifications; represents an upgrade path
3. MPQ8632GLE-12-P – Higher current rating (12A); Tape & Reel packaging; Active product status

All substitute parts maintain the same package footprint, input/output voltage ranges, switching frequency band, and thermal operating window as the MP8761GLE-Z.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Identical Specifications): MP8761GLE-P is the direct equivalent to MP8761GLE-Z. Both parts maintain identical electrical specifications and package footprint. Selection between these two depends solely on packaging format availability: MP8761GLE-Z is supplied in Cut Tape format, while MP8761GLE-P is also available in Cut Tape. Both carry "Not For New Designs" status.

For Upgraded Performance (Higher Current Capability): MPQ8632GLE-12-Z and MPQ8632GLE-12-P provide 12A output current versus the 8A of the MP8761GLE-Z, while maintaining all other electrical parameters and package compatibility. These parts carry Active product status, making them suitable for new designs. MPQ8632GLE-12-Z is available in standard packaging, while MPQ8632GLE-12-P is supplied in Tape & Reel format.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), ensuring regulatory and environmental compatibility with the original MP8761GLE-Z.

Frequently Asked Questions (FAQ)

Q: Can MP8761GLE-P be used as a direct replacement for MP8761GLE-Z? A: Yes. Both parts are electrically and mechanically identical, with specifications matching across input voltage range (4.5V–18V), output voltage range (0.611V–13V), current output (8A), switching frequency (200kHz–1MHz), and package type (16-QFN 3x4). The difference is packaging format only.

Q: What is the advantage of using MPQ8632GLE-12-Z or MPQ8632GLE-12-P instead of MP8761GLE-Z? A: The MPQ8632 series provides 12A output current compared to 8A in the MP8761GLE-Z. All other electrical specifications remain identical: input voltage range, output voltage adjustability, switching frequency, and thermal operating window. Additionally, the MPQ8632 series carries Active product status, making it suitable for new designs.

Q: Are all substitute parts compatible with the same PCB layout? A: Yes. All substitute parts use the 16-QFN (3x4) package with identical pin configuration and footprint. No PCB redesign is required for substitution.

Q: What is the difference between Cut Tape and Tape & Reel packaging? A: Cut Tape (CT) and Tape & Reel (TR) are supply formats only. Electrically and mechanically, the parts are identical. Cut Tape is typically used for lower-volume applications, while Tape & Reel is standard for high-volume production.

Q: Why is MP8761GLE-Z marked "Not For New Designs"? A: This status 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 carry Active status and provide higher current capability.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All parts listed are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity), ensuring equivalent regulatory and environmental compliance.
