Key Parameters

Substitute Part Grouping Explanation

Substitution of MP6543HGL-B-Z with equivalent parts is determined by strict adherence to the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Base product number: MP6543
• Output current rating: 2A
• Supply voltage range: 3V ~ 22V
• Output configuration: Half Bridge (3)
• Interface type: PWM
• Technology: NMOS
• Package type: 24-VFQFN Exposed Pad
• Supplier device package: 24-QFN (3x4)
• Operating temperature range: -40°C ~ 125°C (TJ)
• Motor application: Brushless DC (BLDC), Multiphase

All substitute parts maintain identical electrical specifications and physical packaging. Variations exist only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability. These packaging differences do not affect electrical performance or functional compatibility in circuit design.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are manufactured by Monolithic Power Systems Inc. and maintain active product status. Each part is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial and commercial applications.

Electrical Compatibility: MP6543HGL-A-P, MP6543HGL-A-Z, MP6543HGL-P, and MP6543HGL-Z are electrically equivalent to MP6543HGL-B-Z. All devices support identical supply voltage ranges (3V ~ 22V), output current specifications (2A), operating temperature ranges (-40°C ~ 125°C), and functional configurations (three half-bridge PWM-controlled outputs for BLDC motor control).

Packaging Considerations: MP6543HGL-B-Z, MP6543HGL-A-P, MP6543HGL-A-Z, and MP6543HGL-P are supplied in Tape & Reel format. MP6543HGL-Z is supplied in Cut Tape & Digi-Reel format. Selection between these packaging options depends on procurement volume requirements and assembly line automation capabilities. The physical package (24-VFQFN Exposed Pad, 24-QFN 3x4) remains identical across all variants.

Inventory Availability: MP6543HGL-Z offers the highest inventory availability (10,346 pcs), followed by MP6543HGL-A-Z (4,975 pcs). MP6543HGL-B-Z maintains 2,378 pcs in stock. Selection based on inventory status is appropriate for high-volume production schedules or extended lead-time mitigation strategies.

Frequently Asked Questions (FAQ)

Q: Are all MP6543HGL variants electrically interchangeable in circuit design?

A: Yes. MP6543HGL-B-Z, MP6543HGL-A-P, MP6543HGL-A-Z, MP6543HGL-P, and MP6543HGL-Z maintain identical electrical specifications including 2A output current, 3V to 22V supply voltage range, three half-bridge PWM outputs, and -40°C to 125°C operating temperature range. Direct substitution in PCB layouts and schematics is supported without circuit modification.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, suitable for high-speed automated pick-and-place assembly. Cut Tape & Digi-Reel packaging supplies components on cut tape segments or alternative reel formats, typically used for lower-volume production or manual assembly processes. Both formats contain identical components in the same 24-VFQFN package.

Q: Can MP6543HGL-Z be used as a substitute for MP6543HGL-B-Z in production?

A: Yes. MP6543HGL-Z is electrically and functionally equivalent to MP6543HGL-B-Z. The only difference is packaging format (Cut Tape & Digi-Reel versus Tape & Reel). Substitution is valid provided assembly equipment can accommodate the alternative packaging format.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (MP6543HGL-A-P, MP6543HGL-A-Z, MP6543HGL-P, and MP6543HGL-Z) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity). Regulatory compliance is maintained across all variants.

Q: Which substitute part offers the best inventory availability?

A: MP6543HGL-Z offers the highest inventory availability with 10,346 pcs in stock, followed by MP6543HGL-A-Z with 4,975 pcs. These variants are suitable for applications requiring immediate component availability or large-volume procurement.

Q: Do all MP6543HGL variants support BLDC motor control applications?

A: Yes. All variants are designed for brushless DC (BLDC) motor control with multiphase capability. Each device integrates fully the control and power stage functions required for three-phase BLDC motor driving via PWM interface.
