Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8632GV-20-Z is determined by strict alignment of the following electrical and mechanical parameters:

• Topology & Function: Buck switching regulator with step-down conversion
• Output Configuration: Positive adjustable output
• Output Current Rating: 20A
• Output Voltage Range: 0.611V to 13V adjustability
• Switching Frequency: 200kHz to 1MHz operation
• Synchronous Rectification: Integrated synchronous rectifier
• Package: 29-VFQFN Exposed Pad (29-QFN 5x4mm)
• Thermal Range: -40°C to 125°C junction temperature
• Compliance: ROHS3, MSL 1, REACH Unaffected

The MPQ8632GVE-20-P qualifies as a direct substitute based on matching all core electrical specifications and package requirements. The primary distinction is the input voltage minimum specification and active product status.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GVE-20-P is the manufacturer-recommended substitute for the MPQ8632GV-20-Z. Both devices share identical electrical performance specifications for output current, voltage range, switching frequency, and thermal operating range. Both maintain ROHS3 compliance and MSL 1 moisture sensitivity classification.

The key distinction is input voltage specification: the MPQ8632GV-20-Z supports operation from 2.5V minimum input, while the MPQ8632GVE-20-P requires 4.5V minimum input. Applications requiring sub-4.5V input operation must retain the MPQ8632GV-20-Z. For applications operating within the 4.5V to 18V input range, the MPQ8632GVE-20-P is the preferred selection due to its active product status and continued manufacturer support.

Both parts are identical in package footprint (29-VFQFN Exposed Pad) and require no PCB layout modifications for substitution within the specified input voltage constraints.

Frequently Asked Questions (FAQ)

Q: Can the MPQ8632GVE-20-P replace the MPQ8632GV-20-Z in all applications?

A: Substitution is valid only for applications where the input voltage remains at or above 4.5V. The MPQ8632GV-20-Z supports lower input voltages starting at 2.5V. If your application requires operation below 4.5V input, the MPQ8632GV-20-Z must be retained.

Q: Are there PCB layout differences between these parts?

A: No. Both parts use the identical 29-VFQFN Exposed Pad package (29-QFN 5x4mm). PCB footprints, trace routing, and thermal management layouts are directly compatible without modification.

Q: What is the significance of the product status difference?

A: The MPQ8632GV-20-Z is marked "Not For New Designs," indicating Monolithic Power Systems has transitioned this part to end-of-life status. The MPQ8632GVE-20-P carries "Active" status, meaning it receives ongoing manufacturer support, updated documentation, and continued availability. New designs should use the MPQ8632GVE-20-P where input voltage specifications permit.

Q: Are output current and voltage specifications identical?

A: Yes. Both parts deliver 20A output current with adjustable output voltage from 0.611V to 13V. Switching frequency range (200kHz to 1MHz) and synchronous rectification capability are identical.

Q: Do compliance certifications differ between these parts?

A: No. Both parts maintain ROHS3 compliance, MSL 1 moisture sensitivity, and REACH Unaffected status. Electrical safety and environmental compliance are equivalent.
