IRMCK371TR Motor Driver IGBT Equivalent & Substitute Parts

Part Overview

The IRMCK371TR is an obsolete motor driver integrated circuit manufactured by Infineon Technologies, designed for AC and synchronous motor control applications. This PMIC (Power Management IC) functions as a commutation and direction management controller with IGBT pre-driver output configuration. Due to its obsolete product status, identifying parametrically equivalent substitute parts is essential for design continuity, system maintenance, and component procurement in legacy appliance applications.

Substitute Part Grouping Explanation

Substitute parts for the IRMCK371TR are identified based on strict parametric equivalence across the following critical criteria:

• Motor Control Function: AC and synchronous motor commutation and direction management capability
• Output Architecture: Pre-driver half-bridge configuration with three output stages
• Communication Interfaces: I2C, RS-232, and SPI protocol support
• Electrical Specifications: Dual voltage supply range (1.62V–1.98V and 3V–3.6V) with identical operating temperature range
• Package Compatibility: 48-pin LQFP surface mount package with 7x7mm footprint
• Environmental Compliance: MSL 3 rating and REACH unaffected status

The IRMCF371TR meets all these parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The IRMCF371TR is a direct parametric equivalent to the IRMCK371TR and is suitable for substitution in applications requiring AC and synchronous motor control with IGBT pre-driver functionality. Both parts share identical electrical specifications, package geometry, and environmental compliance ratings. The IRMCF371TR carries RoHS3 compliance certification, providing enhanced regulatory alignment for new designs and legacy system updates. Selection between these parts should be based on availability, supply chain considerations, and compliance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can the IRMCF371TR be used as a direct replacement for the IRMCK371TR?

A: Yes. The IRMCF371TR is parametrically equivalent across all critical specifications including motor control function, output configuration, communication interfaces, voltage supply range, operating temperature, and package geometry. Direct substitution is supported without circuit modification.

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

A: Both parts are REACH unaffected and carry EAR99 export classification. The IRMCF371TR includes RoHS3 compliance certification, while the IRMCK371TR does not specify this status. Both maintain MSL 3 moisture sensitivity rating.

Q: What is the significance of the package designation 48-QFP (7x7)?

A: This indicates a 48-pin Quad Flat Pack with 7mm × 7mm body dimensions. Both the IRMCK371TR and IRMCF371TR use this identical package, ensuring mechanical and electrical compatibility on PCB layouts designed for either part.

Q: Why is the IRMCK371TR listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Infineon Technologies. The IRMCF371TR serves as the current equivalent for applications requiring this motor driver functionality.

Q: Are the dual voltage supply ranges (1.62V–1.98V and 3V–3.6V) interchangeable?

A: The part supports both voltage ranges as specified. System design must select one range based on application requirements. Both substitute parts support identical voltage specifications.

Q: What applications are these motor driver ICs designed for?

A: These parts are specified for appliance applications requiring AC and synchronous motor control with commutation and direction management functions.
