Key Parameters

Substitute Part Grouping Explanation

All substitute parts for the MP6543HGL-P share identical electrical specifications and mechanical compatibility. Substitution is determined by the following parameters, which are constant across all equivalent parts:

Electrical Parameters (Identical):

• Supply voltage range: 3V ~ 22V
• Output current: 2A
• Output configuration: Three half-bridge stages
• Interface: PWM control
• Technology: NMOS
• Operating temperature: -40°C ~ 125°C (TJ)
• Motor applications: Brushless DC (BLDC) and multiphase stepper

Mechanical Parameters (Identical):

• Package: 24-VFQFN Exposed Pad
• Device package: 24-QFN (3x4)
• Mounting: Surface Mount

Compliance Parameters (Identical):

• RoHS3 Compliant
• REACH Unaffected
• Moisture Sensitivity Level 1
• ECCN: EAR99
• HTSUS: 8542.39.0001

The only variation among substitute parts is the packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and inventory availability. All parts are manufactured by Monolithic Power Systems Inc. and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full compatibility with the MP6543HGL-P in terms of electrical performance, mechanical fit, and regulatory compliance. Selection among equivalent parts is based on the following criteria:

Packaging Format Consideration: The MP6543HGL-Z variant is supplied in Cut Tape (CT) & Digi-Reel® format, while MP6543HGL-P, MP6543HGL-A-P, MP6543HGL-A-Z, and MP6543HGL-B-Z are supplied in Tape & Reel (TR) format. Choose the packaging format that aligns with assembly equipment and procurement workflows.

Inventory Availability: MP6543HGL-A-Z offers the highest inventory level at 4975 units, followed by MP6543HGL-Z at 10346 units in Cut Tape format. MP6543HGL-P maintains 1552 units in stock. Selection based on inventory should account for lead time and supply chain requirements.

Compliance and Regulatory Status: All substitute parts are ROHS3 Compliant, REACH Unaffected, and carry identical moisture sensitivity and ECCN classifications. No regulatory differentiation exists among the parts.

Product Status: All parts maintain active product status with Monolithic Power Systems Inc., ensuring continued support and availability.

Frequently Asked Questions (FAQ)

Q: Can MP6543HGL-A-P be used as a direct replacement for MP6543HGL-P?

A: Yes. Both parts share identical electrical specifications (3V ~ 22V supply, 2A output current, three half-bridge configuration), mechanical packaging (24-VFQFN Exposed Pad, 24-QFN 3x4), and compliance certifications. Both are supplied in Tape & Reel format.

Q: What is the difference between MP6543HGL-Z and MP6543HGL-P?

A: The electrical and mechanical specifications are identical. The primary difference is packaging format: MP6543HGL-Z is supplied in Cut Tape (CT) & Digi-Reel® format, while MP6543HGL-P is supplied in Tape & Reel (TR) format. MP6543HGL-Z also has significantly higher inventory availability (10346 units versus 1552 units).

Q: Are all substitute parts suitable for BLDC motor control applications?

A: Yes. All substitute parts are specified for brushless DC (BLDC) motor control with identical three-phase half-bridge output configurations, PWM interface, and NMOS technology. Operating temperature range (-40°C ~ 125°C) and supply voltage range (3V ~ 22V) are identical across all parts.

Q: Do the suffix variations (A-P, A-Z, B-Z, Z) affect electrical performance?

A: No. The suffix variations indicate packaging format and internal manufacturing designations but do not alter electrical performance, output current capability, voltage specifications, or thermal characteristics. All parts are functionally equivalent.

Q: Which substitute part should be selected for high-volume production?

A: MP6543HGL-A-Z and MP6543HGL-Z offer the highest inventory levels (4975 and 10346 units respectively). MP6543HGL-A-Z is available in Tape & Reel format, while MP6543HGL-Z is available in Cut Tape & Digi-Reel® format. Selection depends on assembly equipment compatibility.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts carry ROHS3 Compliant status with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected classification. No environmental or regulatory differentiation exists among the parts.

Q: Can MP6543HGL-Z be used in automated pick-and-place assembly?

A: MP6543HGL-Z is supplied in Cut Tape (CT) & Digi-Reel® format, which is compatible with standard automated assembly equipment. Tape & Reel format variants (MP6543HGL-P, MP6543HGL-A-P, MP6543HGL-A-Z, MP6543HGL-B-Z) are also suitable for automated assembly. Verify compatibility with specific assembly equipment specifications.
