Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPQ8632GV-20-P is determined by strict alignment of the following critical parameters:

• Package and pinout compatibility: 29-VFQFN Exposed Pad form factor
• Output current capability: 20A minimum
• Adjustable output voltage range: 0.611V to 13V
• Input voltage operating range: Minimum 2.5V to maximum 18V
• Switching frequency: 200kHz to 1MHz
• Synchronous rectification: Required
• Operating temperature range: -40°C to 125°C (TJ)
• Surface mount technology compatibility
• RoHS3 compliance and MSL Level 1 rating

The MPQ8632GVE-20-P meets all these criteria and is classified as a direct substitute. The primary distinction is the input voltage minimum specification, which differs between the two variants.

Parameter Comparison

Engineering Selection Recommendations

The MPQ8632GVE-20-P is the recommended substitute for the MPQ8632GV-20-P. The substitute part carries Active product status, ensuring continued availability and manufacturer support, whereas the original part is designated "Not For New Designs." Both parts maintain identical compliance certifications including ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating.

The primary design consideration is the input voltage minimum specification: the substitute part requires a minimum input voltage of 4.5V compared to 2.5V for the original. Applications operating below 4.5V input voltage cannot use the MPQ8632GVE-20-P as a direct substitute. For all other applications within the 4.5V to 18V input range, the substitute part provides equivalent electrical and mechanical performance with the advantage of active product lifecycle status.

Frequently Asked Questions (FAQ)

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

A: The MPQ8632GVE-20-P is a direct substitute for applications where the input voltage remains between 4.5V and 18V. If your application requires operation below 4.5V input voltage, the original MPQ8632GV-20-P specification must be maintained, as the substitute part does not support this lower input voltage range.

Q: What is the significance of the "Not For New Designs" status on the MPQ8632GV-20-P?

A: This designation indicates the part is in mature or end-of-life phase and is not recommended for new product development. The MPQ8632GVE-20-P, with Active status, is the preferred choice for new designs and ongoing production.

Q: Are the package and pinout configurations identical between these two parts?

A: Yes. Both parts use the 29-VFQFN Exposed Pad package with identical pinout and mechanical dimensions, ensuring direct PCB compatibility without layout modifications.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both the MPQ8632GV-20-P and MPQ8632GVE-20-P are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. Operating temperature ranges are identical at -40°C to 125°C (TJ).

Q: What output current and voltage specifications apply to both parts?

A: Both parts deliver 20A output current with an adjustable output voltage range from 0.611V to 13V. Switching frequency, synchronous rectification capability, and thermal performance are identical across both variants.
