MP9928GL-P Equivalent & Substitute Parts

Part Overview

The MP9928GL-P is an active Buck Regulator Positive Output Step-Down DC-DC Controller IC manufactured by Monolithic Power Systems. This 20-QFN (3x4) surface mount device operates across a 4V to 60V input voltage range and functions as a transistor driver for step-down topology applications. The part is currently in active production status with 1156 pieces available in original inventory. Substitute parts are identified when packaging format, supplier logistics, or regional availability require alternative sourcing while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

The MP9928GL-P has one identified substitute: MP9928GL-Z. Both parts share the identical base product number (MP9928) and are manufactured by Monolithic Power Systems Inc. The substitution is valid based on the following criteria:

All electrical parameters are identical: input voltage range (4V ~ 60V), switching frequency (100kHz ~ 1MHz), duty cycle maximum (99.5%), output type (transistor driver), function (step-down), topology (buck), output configuration (positive), number of outputs (1), output phases (1), synchronous rectifier capability, clock sync, control features (Enable, Phase Control, Power Good, Soft Start), and operating temperature range (-40°C ~ 125°C).

All mechanical parameters are identical: package type (20-TFQFN Exposed Pad), supplier device package (20-QFN 3x4), and mounting type (surface mount).

All compliance and regulatory parameters are identical: RoHS3 Compliant, Moisture Sensitivity Level 1 (Unlimited), REACH Unaffected, ECCN EAR99, and HTSUS 8542.39.0001.

The only difference between the parts is the packaging format: MP9928GL-P is supplied in Tape & Reel (TR) format, while MP9928GL-Z is supplied in Cut Tape (CT) & Digi-Reel® format.

Engineering Selection Recommendations

Both MP9928GL-P and MP9928GL-Z are active production parts from Monolithic Power Systems with identical electrical, mechanical, and compliance specifications. Selection between these parts is determined by packaging and supply chain requirements rather than technical performance.

MP9928GL-P in Tape & Reel format is suitable for high-volume automated assembly operations where continuous reel feeding is required. MP9928GL-Z in Cut Tape & Digi-Reel® format provides flexibility for lower-volume applications, mixed component orders, or situations where partial reel quantities are needed.

Both parts meet ROHS3 compliance, REACH unaffected status, and carry MSL Level 1 (Unlimited) moisture sensitivity rating, making them suitable for standard storage and handling conditions without special precautions.

Frequently Asked Questions (FAQ)

Q: Can MP9928GL-Z be used as a direct replacement for MP9928GL-P in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Direct substitution is valid from a functional standpoint. Assembly process compatibility depends on your equipment's ability to handle the different packaging format.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) supplies components on continuous reels suitable for automated pick-and-place machines. Cut Tape (CT) & Digi-Reel® provides components in tape segments or alternative reel formats, offering flexibility for lower-volume orders or mixed component sourcing.

Q: Are there any electrical performance differences between MP9928GL-P and MP9928GL-Z?

A: No. Both parts have identical electrical specifications including input voltage range (4V ~ 60V), switching frequency (100kHz ~ 1MHz), duty cycle (99.5% max), control features, and operating temperature range (-40°C ~ 125°C).

Q: Do both parts meet the same compliance standards?

A: Yes. Both MP9928GL-P and MP9928GL-Z are ROHS3 Compliant, REACH Unaffected, and carry identical regulatory classifications (ECCN EAR99, HTSUS 8542.39.0001).

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts carry MSL Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Can I mix MP9928GL-P and MP9928GL-Z in the same production batch?

A: Yes, from a functional and compliance perspective. However, assembly line compatibility depends on whether your equipment can process both packaging formats. Consult your assembly process documentation.
