MP6550GG-Z Equivalent & Substitute Parts

Part Overview

The MP6550GG-Z is an active, production-status unipolar motor driver integrated circuit manufactured by Monolithic Power Systems Inc. This power management IC integrates control and power stage functionality for brushed DC motor applications, operating across a 1.8V to 22V supply range with 2A output current capability. The device is housed in a 12-QFN (2x2) surface mount package and is supplied in Cut Tape (CT) & Digi-Reel® packaging format.

Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and functional characteristics are maintained across different packaging or distribution formats. Identifying alternative part numbers ensures design flexibility, supply chain continuity, and procurement optimization without compromising circuit performance or reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6550GG-Z is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Voltage supply range: 1.8V ~ 22V
• Output current rating: 2A
• Motor type support: Unipolar stepper and brushed DC motor capability
• Output configuration: Half Bridge (4)
• Interface protocol: PWM

Mechanical & Package Equivalence Requirements:

• Package type: 12-VFQFN (2x2)
• Mounting type: Surface Mount
• Supplier device package: 12-QFN (2x2)

Compliance & Status Requirements:

• Product status: Active
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• REACH status: REACH Unaffected

The MP6550GG-P qualifies as a parametric equivalent substitute. Both parts share identical electrical specifications, functional architecture, and mechanical packaging. The distinction between these part numbers is limited to packaging format: the MP6550GG-Z is supplied in Cut Tape (CT) & Digi-Reel® format, while the MP6550GG-P is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly logistics but does not alter component performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6550GG-Z and MP6550GG-P are active production components manufactured by Monolithic Power Systems Inc. and maintain full ROHS3 compliance and REACH unaffected status. Selection between these parts is determined by packaging and procurement requirements rather than electrical or functional performance.

MP6550GG-Z (Cut Tape & Digi-Reel® Format): Suitable for applications requiring smaller order quantities, prototype development, or mixed component procurement where individual component handling is preferred.

MP6550GG-P (Tape & Reel Format): Suitable for high-volume production environments, automated assembly processes, and applications where reel-based component feeding is standard practice.

Both parts deliver identical electrical performance, thermal characteristics, and compliance certifications. Circuit design, PCB layout, and functional behavior remain unchanged regardless of which part number is selected. The choice between these substitutes is a procurement and manufacturing logistics decision.

Frequently Asked Questions (FAQ)

Q: Are MP6550GG-Z and MP6550GG-P electrically identical?

A: Yes. Both parts share identical electrical specifications including voltage supply range (1.8V ~ 22V), output current (2A), motor type support (unipolar stepper and brushed DC), output configuration (half bridge), interface protocol (PWM), and operating temperature range (-40°C ~ 125°C). Circuit performance and functionality are equivalent.

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

A: The primary difference is packaging format. The MP6550GG-Z is supplied in Cut Tape (CT) & Digi-Reel® format, while the MP6550GG-P is supplied in Tape & Reel (TR) format. This affects component handling, storage, and assembly processes but does not alter device performance.

Q: Can I use MP6550GG-P as a direct replacement for MP6550GG-Z in my design?

A: Yes. Both parts are housed in the 12-VFQFN (2x2) surface mount package with identical pinout and electrical characteristics. Direct substitution is possible from a circuit design perspective. Verify that your assembly process and component handling equipment are compatible with the Tape & Reel format if switching from Cut Tape.

Q: Are both parts currently in production?

A: Yes. Both the MP6550GG-Z and MP6550GG-P maintain active product status with Monolithic Power Systems Inc.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited) ratings.

Q: Which part should I specify for high-volume production?

A: The MP6550GG-P (Tape & Reel format) is optimized for high-volume automated assembly processes. The MP6550GG-Z (Cut Tape & Digi-Reel®) is suitable for lower-volume or mixed procurement scenarios.

Q: Is there a performance difference between the two packaging formats?

A: No. Packaging format does not affect electrical performance, thermal characteristics, or functional behavior. Both formats contain the identical die and deliver the same circuit performance.
