MP8848GD-Z Equivalent & Substitute Parts

Part Overview

The MP8848GD-Z is a buck switching regulator IC from Monolithic Power Systems Inc., designed for positive adjustable output voltage regulation with 6A output current capability. This device operates across a 2.7V to 6V input range and delivers adjustable output voltage from 0.6V to 1.23V at 1.25MHz switching frequency in a 15-PowerVFQFN package.

The MP8848GD-Z carries a "Not For New Designs" product status, indicating it has been superseded. Identifying equivalent substitute parts is necessary for ongoing production support, legacy system maintenance, and design continuity where this component is already deployed.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP8848GD-Z is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Input voltage range: 2.7V to 6V
• Output voltage range: 0.6V to 1.23V
• Output current capability: 6A
• Switching frequency: 1.25MHz
• Synchronous rectifier topology: Yes
• Operating temperature range: -40°C to 125°C
• Output configuration: Positive adjustable (programmable)
• Mounting type: Surface mount

Package Compatibility Consideration: The MP8848GD-Z uses a 15-PowerVFQFN package. Substitute parts may use alternative QFN packages provided pin count, pitch, and functional pinout remain compatible with the application circuit.

The MP8847GD-Z qualifies as a manufacturer-recommended substitute, meeting all electrical specifications while utilizing a 14-VFQFN package variant.

Parameter Comparison

Engineering Selection Recommendations

The MP8847GD-Z is the manufacturer-designated substitute for the MP8848GD-Z. Both devices are ROHS3 compliant and carry MSL Level 1 rating, indicating equivalent environmental and handling requirements.

The primary distinction is product lifecycle status: the MP8847GD-Z maintains Active status, ensuring continued availability and manufacturing support, whereas the MP8848GD-Z is designated Not For New Designs. For applications currently using the MP8848GD-Z, the MP8847GD-Z provides electrical and functional equivalence with the advantage of ongoing product support.

Package geometry differs between the two variants (15-PowerVFQFN versus 14-VFQFN). PCB layout modifications are required to accommodate the alternative package footprint. Both packages are surface-mount QFN variants with compatible pitch specifications for standard assembly processes.

Frequently Asked Questions (FAQ)

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

A: Electrical specifications are identical, enabling functional substitution. However, the package footprint differs (15-PowerVFQFN versus 14-VFQFN), requiring PCB layout redesign. Pin functionality and electrical performance remain equivalent.

Q: What is the significance of the "Not For New Designs" status on the MP8848GD-Z?

A: This designation indicates the part has been superseded in the manufacturer's product line. The MP8847GD-Z is the active replacement. Existing designs using the MP8848GD-Z can transition to the MP8847GD-Z for continued production support.

Q: Are there compliance or certification differences between these parts?

A: Both parts carry identical RoHS3 compliance and MSL Level 1 ratings. No compliance or certification distinctions exist between the two devices.

Q: What are the key parameters that determine substitution eligibility?

A: Input voltage range (2.7V–6V), output voltage range (0.6V–1.23V), output current (6A), switching frequency (1.25MHz), synchronous rectifier topology, and operating temperature range (-40°C to 125°C) must remain constant. Package form factor may vary provided pinout compatibility is maintained.

Q: Is the MP8847GD-Z available in the same packaging as the MP8848GD-Z?

A: No. The MP8847GD-Z uses a 14-VFQFN package, while the MP8848GD-Z uses a 15-PowerVFQFN package. Both are surface-mount QFN variants with compatible pitch, but physical footprints differ, necessitating PCB layout updates.
