Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MP6651GD-0000-Z is determined by strict equivalence across the following critical parameters:

Motor Control Specifications: Both the main part and substitute must support Brushless DC (BLDC) motor control with bipolar motor type capability, fully integrated control and power stage functionality, and half-bridge output configuration.

Electrical Performance: Output current rating of 2A, supply voltage range of 3.3V to 18V, load voltage range of 3.3V to 18V, and PWM interface are mandatory for functional equivalence.

Thermal and Environmental: Operating temperature range of -40°C to 125°C (junction temperature) ensures compatibility across specified application environments.

Package and Mounting: 10-QFN (2x3) package in surface mount configuration is required for mechanical and electrical compatibility on printed circuit boards.

Compliance and Certifications: ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status ensure regulatory and environmental compatibility.

The MP6651GD-0000-P meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both MP6651GD-0000-Z and MP6651GD-0000-P are Active product status components manufactured by Monolithic Power Systems Inc. with identical electrical, thermal, mechanical, and compliance specifications. Selection between these parts is based on procurement and inventory considerations rather than technical performance differences.

MP6651GD-0000-Z is recommended as the primary selection due to higher inventory availability (5669 units in stock), supporting consistent supply chain management and reduced lead times.

MP6651GD-0000-P serves as a direct substitute when MP6651GD-0000-Z availability is constrained. With 1563 units in stock, this part maintains identical functional and compliance characteristics for applications requiring 2A brushless DC motor driver capability in the 3.3V to 18V operating range.

Both parts satisfy ROHS3 compliance and REACH regulatory requirements, with MSL Level 1 (Unlimited) moisture sensitivity classification suitable for standard storage and handling conditions. The 10-QFN (2x3) surface mount package is identical across both parts, ensuring no PCB layout or assembly process modifications are required during substitution.

Frequently Asked Questions (FAQ)

Q: Are MP6651GD-0000-Z and MP6651GD-0000-P electrically interchangeable?

A: Yes. Both parts are parametric equivalents with identical electrical specifications including 2A output current, 3.3V to 18V supply and load voltage ranges, PWM interface, and -40°C to 125°C operating temperature range. No circuit modifications are required for substitution.
