Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP8762GLE-Z are identified based on strict electrical and mechanical compatibility criteria. The primary substitutes are MPQ8632GLE-12-Z and MPQ8632GLE-12-P, both from Monolithic Power Systems Inc.

The substitution logic is based on the following key parameters that must remain consistent or compatible:

• Input voltage range: 4.5V to 18V (identical across all parts)
• Output voltage range: 0.611V to 13V (identical across all parts)
• Output configuration: Positive adjustable (identical across all parts)
• Topology: Buck switching regulator (identical across all parts)
• Synchronous rectifier: Yes (identical across all parts)
• Operating temperature range: -40°C to 125°C (identical across all parts)
• Package / Case: 16-PowerVFQFN (3x4) (identical across all parts)
• Mounting type: Surface Mount (identical across all parts)
• Switching frequency range: 200kHz ~ 1MHz (identical across all parts)
• Compliance: ROHS3 Compliant, REACH Unaffected (identical across all parts)

The primary difference between the main part and substitutes is the output current rating: the MP8762GLE-Z delivers 10A, while the MPQ8632 series delivers 12A. This represents an upgrade in current capacity while maintaining all other electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GLE-12-Z and MPQ8632GLE-12-P are direct functional equivalents to the MP8762GLE-Z with enhanced output current capability. Both substitute parts maintain identical electrical specifications across input voltage, output voltage range, switching frequency, and thermal operating range. The 16-PowerVFQFN package footprint is identical, ensuring PCB-level compatibility without layout modifications.

The primary distinction between the two substitutes is packaging format: MPQ8632GLE-12-Z is supplied in standard packaging, while MPQ8632GLE-12-P is supplied in Tape & Reel (TR) format for automated assembly processes. Both parts carry Active product status, indicating ongoing manufacturer support and availability, in contrast to the MP8762GLE-Z which is designated Not For New Designs.

All three parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The 12A output current rating of the MPQ8632 series provides additional design margin compared to the 10A rating of the MP8762GLE-Z, while maintaining backward compatibility with existing circuit designs that do not exceed 10A load requirements.

Frequently Asked Questions (FAQ)

Q: Can MPQ8632GLE-12-Z or MPQ8632GLE-12-P be used as direct replacements for MP8762GLE-Z?

A: Yes. Both MPQ8632 variants are electrically and mechanically compatible. All critical parameters—input voltage range (4.5V–18V), output voltage range (0.611V–13V), package type (16-PowerVFQFN), and thermal specifications—are identical. The 12A output current rating of the MPQ8632 series exceeds the 10A specification of the MP8762GLE-Z, providing additional current capacity without compromising compatibility.

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

A: Both parts are electrically identical with 12A output current capability. The primary difference is packaging format: MPQ8632GLE-12-Z uses standard packaging, while MPQ8632GLE-12-P is supplied in Tape & Reel (TR) format optimized for automated pick-and-place assembly. Selection depends on manufacturing process requirements.

Q: Are there any PCB layout changes required when substituting MP8762GLE-Z with MPQ8632GLE-12-Z or MPQ8632GLE-12-P?

A: No. Both substitute parts use the identical 16-PowerVFQFN (3x4) package footprint. PCB layouts designed for MP8762GLE-Z require no modification for the MPQ8632 series.

Q: Why is MP8762GLE-Z marked as "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status in the manufacturer's product lifecycle. The MPQ8632GLE-12-Z and MPQ8632GLE-12-P are Active products with ongoing manufacturer support, making them preferred choices for new designs and long-term supply assurance.

Q: Do all three parts meet the same compliance standards?

A: Yes. MP8762GLE-Z, MPQ8632GLE-12-Z, and MPQ8632GLE-12-P are all ROHS3 Compliant and REACH Unaffected, satisfying regulatory requirements for industrial, commercial, and consumer applications.

Q: What is the switching frequency range for these buck regulators?

A: All three parts operate within the 200kHz to 1MHz switching frequency range, providing flexibility for application-specific frequency selection and optimization.
