Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MPQ8632GV-15-Z is determined by the following critical parameters:

• Topology and Function: Buck switching regulator with step-down conversion
• Output Configuration: Positive adjustable output
• Current Rating: 15A output capability
• Package: 29-VFQFN Exposed Pad (29-QFN 5x4)
• Mounting Type: Surface Mount
• Output Voltage Range: 0.611V to 13V adjustable
• Switching Frequency: 200kHz to 1MHz
• Synchronous Rectifier: Integrated
• Operating Temperature Range: -40°C to 125°C (TJ)
• Compliance: ROHS3, MSL 1

The MPQ8632GVE-15-P qualifies as a substitute based on matching all critical electrical and mechanical parameters. The primary difference is the input voltage minimum specification (4.5V vs. 2.5V), which represents a narrower input range but maintains full compatibility for applications operating within the 4.5V to 18V window.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GVE-15-P is the qualified substitute for the MPQ8632GV-15-Z. Selection between these parts should be based on the following criteria:

MPQ8632GV-15-Z: Use only for existing designs or applications requiring the extended 2.5V minimum input voltage specification. This part is classified as Not For New Designs and has limited inventory availability (3792 pcs).

MPQ8632GVE-15-P: Preferred for new designs and ongoing production. This part carries Active product status from the manufacturer, ensuring long-term availability and support. It is suitable for all applications operating within the 4.5V to 18V input range. Current inventory is 1044 pcs.

Both parts share identical package geometry, thermal characteristics, output current capability, and compliance certifications. The substitution is mechanically and electrically valid for applications where the input voltage minimum of 4.5V is acceptable.

Frequently Asked Questions (FAQ)

Q: Can the MPQ8632GVE-15-P directly replace the MPQ8632GV-15-Z in existing designs?

A: Yes, provided the application input voltage remains at or above 4.5V. The substitute part maintains identical package footprint (29-VFQFN), pinout, output current rating (15A), and thermal operating range. No PCB layout modifications are required.

Q: What is the key difference between these two parts?

A: The primary difference is the minimum input voltage specification. The MPQ8632GV-15-Z operates from 2.5V minimum, while the MPQ8632GVE-15-P operates from 4.5V minimum. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and meet identical regulatory requirements (REACH Unaffected, ECCN EAR99, HTSUS 8542.39.0001).

Q: Which part should be used for new designs?

A: The MPQ8632GVE-15-P should be used for new designs. It carries Active product status, ensuring manufacturer support and long-term availability. The MPQ8632GV-15-Z is classified as Not For New Designs.

Q: Are the packages identical?

A: Yes. Both parts use the 29-VFQFN Exposed Pad package (29-QFN 5x4 form factor) with surface mount technology. They are pin-compatible and footprint-compatible.

Q: What applications are suitable for substitution?

A: The MPQ8632GVE-15-P is suitable for any buck regulator application requiring 15A output current, adjustable positive output voltage (0.611V to 13V), and input voltage between 4.5V and 18V. Applications requiring input voltages below 4.5V must use the original MPQ8632GV-15-Z.
