MP6500GU-P Equivalent & Substitute Parts

Part Overview

The MP6500GU-P is a bipolar stepper motor driver IC manufactured by Monolithic Power Systems Inc., classified as a Power Management PMIC. This fully integrated motor driver combines control and power stage functionality in a 24-QFN (5x5) surface mount package. The device supports step resolutions of 1, 1/2, 1/4, and 1/8, with applications in printer mechanisms and other stepper motor control systems. The MP6500GU-P is currently in active production status with 1,369 units in stock. Equivalent substitute parts are identified based on matching electrical specifications, mechanical packaging, and functional capabilities to ensure direct interchangeability in circuit designs.

Substitute Part Grouping Explanation

Substitute parts for the MP6500GU-P are identified based on strict parameter matching across electrical and mechanical specifications. The substitution logic is organized into two categories:

Packaging Variant Substitutes (Same Base Product): MP6500GU-Z shares identical electrical specifications and packaging with MP6500GU-P. The only difference is the packaging designation (Z vs. P suffix), representing different tape and reel configurations. Both parts are functionally equivalent and mechanically interchangeable.

Cross-Series Parametric Equivalents (MP6601 Series): MP6601GU-P and MP6601GU-Z are parametric equivalents to MP6500GU-P. These parts maintain identical electrical performance across all critical parameters: 2.5A output current, 4.5V–35V supply voltage range, 3.3V/5V load voltage support, -40°C to 125°C operating temperature, half-bridge (4) output configuration, and 24-QFN (5x5) package. The MP6601 series represents an alternative product line within the same manufacturer's motor driver portfolio, offering equivalent functionality for direct circuit substitution.

Key Parameters Determining Substitution:

• Output current rating (2.5A)
• Supply voltage range (4.5V ~ 35V)
• Load voltage compatibility (3.3V, 5V)
• Output configuration (Half Bridge × 4)
• Package type (24-VFQFN Exposed Pad)
• Step resolution support (1, 1/2, 1/4, 1/8)
• Operating temperature range (-40°C ~ 125°C)

Engineering Selection Recommendations

All four parts—MP6500GU-P, MP6500GU-Z, MP6601GU-P, and MP6601GU-Z—are active production components manufactured by Monolithic Power Systems Inc. and maintain ROHS3 compliance with identical MSL ratings. Selection between these parts should be based on the following criteria:

MP6500GU-P vs. MP6500GU-Z: These parts are functionally identical. Selection depends on tape and reel packaging requirements specified in procurement documentation. MP6500GU-Z currently has higher inventory availability (9,992 units vs. 1,369 units).

MP6500 Series vs. MP6601 Series: Both series deliver equivalent electrical performance and are mechanically interchangeable. The MP6601 series offers higher inventory levels across both packaging variants (MP6601GU-P: 919 units; MP6601GU-Z: 6,099 units), which may influence lead time and supply chain considerations.

All parts meet the same regulatory and compliance requirements, including REACH unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can MP6500GU-Z be used as a direct replacement for MP6500GU-P? A: Yes. Both parts are electrically and mechanically identical. The difference is limited to tape and reel packaging configuration. Direct substitution is valid for circuit design purposes.

Q: Are MP6601GU-P and MP6601GU-Z compatible with designs specified for MP6500GU-P? A: Yes. The MP6601 series maintains identical electrical specifications across all critical parameters: output current (2.5A), supply voltage range (4.5V–35V), load voltage support (3.3V, 5V), operating temperature (-40°C to 125°C), output configuration (half-bridge × 4), and package type (24-VFQFN). Direct circuit substitution is supported.

Q: What is the difference between the P and Z packaging designations? A: The P and Z suffixes indicate different tape and reel configurations for surface mount assembly. Both are standard packaging variants. Selection should align with your assembly equipment specifications and procurement requirements.

Q: Do all substitute parts have the same moisture sensitivity level? A: Yes. All four parts carry MSL rating 2 (1 Year), indicating identical moisture handling and storage requirements.

Q: Are there any compliance or regulatory differences between these parts? A: No. All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Regulatory status is identical across all variants.

Q: Which part should I select based on current availability? A: MP6500GU-Z and MP6601GU-Z offer the highest inventory levels (9,992 and 6,099 units respectively). Selection should be based on your packaging requirements and supply chain lead time considerations.
