MP6500LGU-Z Equivalent & Substitute Parts

Part Overview

The MP6500LGU-Z is a 35V, 2.5A bipolar stepper motor driver manufactured by Monolithic Power Systems Inc. This fully integrated power management IC combines control and power stage functionality in a 24-QFN (5x5) surface mount package. The device supports multiple step resolutions (1, 1/2, 1/4, 1/8) and operates across a supply voltage range of 4.5V to 35V, making it suitable for printer applications and other stepper motor control systems.

The MP6500LGU-Z is an active product with full RoHS3 compliance and REACH unaffected status. Equivalent substitute parts may be required due to inventory availability, supply chain considerations, or specific packaging preferences while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6500LGU-Z are determined by strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

Electrical Specifications: Motor driver type (bipolar stepper), output current rating (2.5A), supply voltage range (4.5V ~ 35V), step resolution support (1, 1/2, 1/4, 1/8), interface protocol (On/Off, PWM, Step/Direction), and NMOS technology platform.

Mechanical & Package Specifications: 24-QFN (5x5) package with exposed pad, surface mount configuration, and 24-VFQFN case designation.

Compliance & Environmental: RoHS3 compliance, REACH unaffected status, MSL 2 rating, and operating temperature range (-40°C ~ 125°C).

Manufacturer Consistency: All substitute parts are sourced from Monolithic Power Systems Inc. to ensure design continuity and support consistency.

Parts that deviate from any of these parameters are not considered equivalent substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the MP6500LGU-Z and MP6500LGU-P are active products from Monolithic Power Systems Inc. with identical electrical specifications, package configurations, and compliance certifications. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

MP6500LGU-Z is the primary part number with 5696 units in stock, providing the highest availability for immediate procurement.

MP6500LGU-P is a parametric equivalent with 1698 units in stock, suitable for applications where the primary part number is unavailable or when supply chain diversification is required.

Both parts maintain full RoHS3 compliance and REACH unaffected status, ensuring regulatory compliance across all applications. The identical MSL 2 rating and operating temperature range (-40°C ~ 125°C) support deployment in equivalent environmental conditions.

Frequently Asked Questions (FAQ)

Q: Are MP6500LGU-Z and MP6500LGU-P electrically interchangeable?
