MP6541GQKT-P Equivalent & Substitute Parts

Part Overview

The MP6541GQKT-P is a 45V 8A three-phase power stage with fully integrated control and power stage functionality, designed for multiphase motor driver applications including stepper and brushless DC (BLDC) motor control. This Power MOSFET PWM driver operates across a supply voltage range of 4.75V to 40V and is housed in a 26-TQFN (6x6) surface mount package. The device is currently in active production status with 724 units in stock.

Substitute parts are identified when design requirements allow for alternative packaging designations or manufacturing batches while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MP6541GQKT-P are qualified based on identical electrical and mechanical parameters across all critical specifications. The substitution logic is based on the following key parameters that must match exactly:

• Voltage rating: 45V
• Current output: 8A
• Supply voltage range: 4.75V ~ 40V
• Load voltage range: 4.75V ~ 40V
• Output configuration: Half Bridge (3)
• Interface: PWM
• Technology: Power MOSFET
• Package: 26-TQFN (6x6)
• Operating temperature range: -40°C ~ 125°C (TJ)
• Mounting type: Surface Mount
• Moisture sensitivity level: 2 (1 Year)

The identified substitutes (MP6541AGQKT-P and MP6541AGQKT-Z) represent alternative part designations from the same manufacturer with identical functional and physical specifications, differing only in packaging batch or distribution designation.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers (MP6541GQKT-P, MP6541AGQKT-P, and MP6541AGQKT-Z) are active production devices from Monolithic Power Systems Inc. with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain requirements rather than technical performance differences.

MP6541AGQKT-Z offers the highest inventory availability at 5684 units, followed by MP6541AGQKT-P at 1335 units, and MP6541GQKT-P at 724 units. All parts carry ECCN EAR99 and HTSUS 8542.39.0001 classifications where applicable.

Frequently Asked Questions (FAQ)

Q: Are MP6541AGQKT-P and MP6541AGQKT-Z direct substitutes for MP6541GQKT-P?

A: Yes. All three part numbers share identical electrical specifications (45V, 8A, 4.75V ~ 40V supply/load voltage), output configuration (Half Bridge 3), interface (PWM), package type (26-TQFN 6x6), and operating temperature range (-40°C ~ 125°C). They are functionally interchangeable in multiphase motor driver applications.

Q: What is the difference between these part numbers?

A: The differences are limited to packaging batch designation or distribution channel. The electrical and mechanical characteristics are identical across all three parts.

Q: Can I use these substitutes in existing PCB designs without modification?

A: Yes. All three parts use the same 26-TQFN (6x6) surface mount package with identical pinout and footprint requirements. No PCB layout changes are necessary.

Q: Which part should I select for new designs?

A: Selection should be based on current inventory availability and supply chain lead times. MP6541AGQKT-Z has the highest stock level, making it suitable for designs with flexible part number requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts carry identical ECCN and HTSUS classifications and share the same moisture sensitivity level (MSL 2, 1 Year).
