MP9928GF-P Equivalent & Substitute Parts

Part Overview

The MP9928GF-P is a buck regulator positive output step-down DC-DC controller IC manufactured by Monolithic Power Systems Inc. This power management IC operates across a 4V to 60V input voltage range and delivers current-mode synchronous control with integrated phase management. The device is actively produced and widely deployed in industrial and commercial power conversion applications. Substitute parts are identified when packaging format or inventory availability requires alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP9928GF-P is limited to the MP9928GF-Z based on strict parametric equivalence. Both parts share identical electrical specifications across all critical parameters: input voltage range (4V ~ 60V), switching frequency capability (100kHz ~ 1MHz), duty cycle maximum (99.5%), output configuration (positive, single phase), topology (buck), synchronous rectifier implementation, clock synchronization, control features, operating temperature range (-40°C ~ 125°C), and package designation (20-TSSOP-EP).

The sole distinction between these parts is packaging format: MP9928GF-P is supplied in Tape & Reel (TR) format, while MP9928GF-Z is supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain identical component-level performance and are manufactured to the same base product specification (MP9928).

Parameter Comparison

Engineering Selection Recommendations

Both MP9928GF-P and MP9928GF-Z are active products manufactured by Monolithic Power Systems Inc. and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

MP9928GF-P in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. MP9928GF-Z in Cut Tape & Digi-Reel® format accommodates lower-volume production runs, prototype development, and applications where partial reel quantities are preferred. Both parts are electrically and mechanically interchangeable at the component level and require no circuit design modifications.

Frequently Asked Questions (FAQ)

Q: Are MP9928GF-P and MP9928GF-Z electrically identical?

A: Yes. Both parts are manufactured to the same base product specification (MP9928) and share identical electrical characteristics, including input voltage range, switching frequency capability, duty cycle, output configuration, control features, and operating temperature range.

Q: What is the difference between these two part numbers?

A: The difference is packaging format only. MP9928GF-P is supplied in Tape & Reel (TR) format, while MP9928GF-Z is supplied in Cut Tape (CT) & Digi-Reel® format. The physical component, pinout, and performance are identical.

Q: Can I substitute MP9928GF-Z for MP9928GF-P in my design?

A: Yes, without any circuit modifications. The parts are pin-compatible and functionally equivalent. Substitution is limited to supply chain and packaging considerations.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (2A, 4 Weeks).

Q: Which packaging format should I select for my application?

A: Select Tape & Reel (MP9928GF-P) for high-volume automated assembly. Select Cut Tape & Digi-Reel® (MP9928GF-Z) for lower-volume production, prototype work, or when partial reel quantities are required.

Q: Is the 20-TSSOP package with exposed pad identical on both parts?

A: Yes. Both parts use the same 20-TSSOP (0.173", 4.40mm Width) Exposed Pad package designation and are mounted identically on PCBs.
