MP8848GD-P Equivalent & Substitute Parts

Part Overview

The MP8848GD-P is a buck switching regulator IC from Monolithic Power Systems Inc., designed for step-down voltage conversion with positive adjustable output. This device delivers 6A output current across a 0.6V to 1.23V adjustable range, operating from a 2.7V to 6V input supply. The part is classified as "Not For New Designs," indicating it has reached end-of-life status. Identifying equivalent substitute parts is necessary for ongoing system support, maintenance, and production continuity where legacy designs remain in service.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP8848GD-P is determined by strict alignment across the following critical parameters:

• Function and topology (step-down buck converter)
• Output configuration (positive adjustable)
• Electrical specifications (input voltage range 2.7V–6V, output range 0.6V–1.23V, 6A output current)
• Switching frequency (1.25MHz)
• Synchronous rectifier presence
• Operating temperature range (-40°C to 125°C)
• Compliance certifications (ROHS3, REACH Unaffected, EAR99)
• Mounting type (surface mount)

The MP8847GD-P qualifies as a direct substitute based on matching all electrical and functional parameters. The primary difference is packaging: MP8848GD-P uses a 15-PowerVFQFN (3x2mm) package, while MP8847GD-P uses a 14-VFQFN (2x3mm) package. Both packages are surface-mount QFN variants with compatible pinout and thermal characteristics for this application class.

Parameter Comparison

Engineering Selection Recommendations

The MP8847GD-P is the qualified substitute for the MP8848GD-P. Both devices are manufactured by Monolithic Power Systems Inc. and maintain identical electrical specifications, compliance certifications, and functional characteristics.

The MP8847GD-P holds Active product status, whereas the MP8848GD-P is designated "Not For New Designs." This status difference makes the MP8847GD-P the preferred choice for ongoing production and system support.

Package geometry differs between the two parts: the MP8848GD-P occupies a 3x2mm footprint (15-PowerVFQFN), while the MP8847GD-P uses a 2x3mm footprint (14-VFQFN). PCB layout modifications are required to accommodate this dimensional change. Both packages are QFN surface-mount variants with compatible thermal and electrical performance for this power management application.

Both parts maintain ROHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and REACH Unaffected status, ensuring regulatory alignment for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can MP8847GD-P directly replace MP8848GD-P without circuit modifications?

A: Electrical substitution is direct. However, package geometry differs (15-PowerVFQFN vs. 14-VFQFN), requiring PCB footprint redesign. Pinout compatibility must be verified against the specific application schematic.

Q: What is the primary reason to substitute MP8848GD-P?

A: The MP8848GD-P is classified "Not For New Designs," indicating end-of-life status. The MP8847GD-P is an Active product from the same manufacturer with identical electrical performance, making it suitable for production continuity and system maintenance.

Q: Are there electrical performance differences between these parts?

A: No. Both devices deliver identical specifications: 6A output current, 0.6V–1.23V adjustable output range, 2.7V–6V input range, 1.25MHz switching frequency, and -40°C to 125°C operating temperature.

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP8848GD-P and MP8847GD-P are ROHS3 compliant, REACH Unaffected, and classified as EAR99 for export control purposes. Both maintain MSL Level 1 (unlimited) moisture sensitivity rating.

Q: What design considerations apply to the package change?

A: The MP8847GD-P uses a smaller 2x3mm QFN package compared to the 3x2mm package of the MP8848GD-P. PCB layout, thermal management, and component placement must be re-evaluated. Thermal performance characteristics remain equivalent for this power class.

Q: Is the MP8847GD-P the only substitute available?

A: Based on the provided data, MP8847GD-P is the qualified substitute meeting all electrical, functional, and compliance requirements for the MP8848GD-P.
