MP6651GD-0000-P Equivalent & Substitute Parts

Part Overview

The MP6651GD-0000-P is a 2A single-phase brushless DC motor driver manufactured by Monolithic Power Systems Inc. This fully integrated power management IC combines control and power stage functionality in a compact 10-QFN (2x3) surface mount package. The device operates across a supply voltage range of 3.3V to 18V and is designed for fan motor driver applications requiring PWM-based control of brushless DC motors. With active product status and full RoHS3 compliance, this component is suitable for new designs and production environments. Identifying equivalent substitute parts ensures design flexibility, supply chain continuity, and alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require alternative procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MP6651GD-0000-P is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Output current rating (2A), supply voltage range (3.3V ~ 18V), load voltage range (3.3V ~ 18V), operating temperature range (-40°C ~ 125°C), and interface type (PWM).

Functional Parameters: Motor driver function (fully integrated control and power stage), motor type support (brushless DC and bipolar stepper), output configuration (half bridge with 2 outputs), and technology platform (power MOSFET).

Mechanical Parameters: Package type (10-VFQFN), supplier device package (10-QFN 2x3), and mounting type (surface mount).

Compliance Parameters: RoHS3 compliance, REACH unaffected status, and moisture sensitivity level (MSL 1).

Product Status: Active status ensures ongoing manufacturer support and availability.

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

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are parametric equivalents manufactured by Monolithic Power Systems Inc. with identical electrical specifications, output current (2A), voltage ranges (3.3V ~ 18V), operating temperature (-40°C ~ 125°C), package type (10-QFN 2x3), and compliance certifications. No design modifications are required for substitution.

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

A: The MP6651GD-0000-P and MP6651GD-0000-Z differ only in their internal manufacturing or packaging designation codes (suffix -P versus -Z). All functional, electrical, and mechanical parameters are identical. The suffix does not indicate performance differences or feature variations.

Q: Can I use MP6651GD-0000-Z as a drop-in replacement for MP6651GD-0000-P?

A: Yes. Both parts use the same 10-QFN (2x3) surface mount package with identical pin configuration and electrical characteristics. PCB layout, component placement, and solder reflow profiles require no modification.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. No additional certifications or compliance documentation is required when substituting between these part numbers.

Q: Which part should I specify for new designs?

A: Either part number is acceptable for new designs. Selection should be based on current supplier inventory, lead time, and procurement pricing. Both parts are active products with ongoing manufacturer support.

Q: What is the operating temperature range for both parts?

A: Both the MP6651GD-0000-P and MP6651GD-0000-Z operate across a junction temperature range of -40°C to 125°C (TJ), suitable for industrial and consumer applications.

Q: Do both parts support PWM control?
