IRMCF341TR Motor Driver IGBT Controller Equivalent & Substitute Parts

Part Overview

The IRMCF341TR is an Infineon Technologies motor driver IC designed for AC and synchronous motor control applications. This device integrates IGBT pre-driver functionality with multiple communication interfaces (I2C, RS-232, SPI) in a 64-pin MQFP package. The product is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system support, redesigns, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IRMCF341TR is determined by strict equivalence across the following critical parameters:

• Motor control function (AC/Synchronous motor commutation and direction management)
• IGBT pre-driver output configuration (Half Bridge × 3)
• Communication interface support (I2C, RS-232, SPI)
• Supply voltage range (1.62V ~ 1.98V and 3V ~ 3.6V)
• Operating temperature range (-40°C ~ 85°C)
• Series designation (MCE™)
• Compliance certifications (ROHS3, REACH Unaffected)

The identified substitute parts IRMCF371TR and IRMCK371TR maintain functional and electrical equivalence across all critical parameters. The primary difference is package configuration: the IRMCF341TR uses a 64-pin MQFP (10x10) package, while both substitutes employ a 48-pin QFP (7x7) package. This package difference requires PCB redesign and is not a direct pin-for-pin replacement.

Parameter Comparison

Engineering Selection Recommendations

Both IRMCF371TR and IRMCK371TR are functionally equivalent to the IRMCF341TR across all electrical and control parameters. Selection between these options depends on the following factors:

IRMCF371TR: Explicitly certified as ROHS3 compliant. Recommended for applications requiring documented RoHS compliance verification. Current inventory: 15,889 units.

IRMCK371TR: RoHS compliance status not specified in available documentation. Higher current inventory availability: 30,100 units. Suitable for applications where RoHS compliance documentation is not a requirement.

Both substitutes require PCB redesign due to package footprint differences (64-pin to 48-pin configuration). Functional firmware and software interfaces remain compatible across all three part numbers within the MCE™ series.

Frequently Asked Questions (FAQ)

Q: Can IRMCF371TR or IRMCK371TR be used as direct pin-for-pin replacements for IRMCF341TR?

A: No. While functionally equivalent, the package difference (64-LQFP vs. 48-LQFP) requires PCB redesign. Pin mapping and footprint are not compatible for direct substitution without circuit board modification.

Q: What is the primary functional difference between IRMCF341TR and its substitutes?

A: There is no functional difference. All three parts provide identical motor control capabilities, communication interfaces, and electrical specifications. The only difference is physical package size.

Q: Are IRMCF371TR and IRMCK371TR interchangeable with each other?

A: Yes, electrically and functionally. Both use the 48-LQFP package and maintain identical specifications. The primary distinction is RoHS compliance documentation for IRMCF371TR.

Q: Why is the IRMCF341TR classified as obsolete?

A: Product status reflects Infineon's lifecycle management. Obsolete designation indicates the part is no longer in active production. Substitutes within the MCE™ series provide continued design support.

Q: What compliance certifications apply to all three parts?

A: All parts are REACH Unaffected and classified under ECCN EAR99. ROHS3 compliance is confirmed for IRMCF341TR and IRMCF371TR. MSL rating of 3 (168 Hours) applies uniformly.

Q: Which substitute should be selected for new designs?

A: Selection depends on compliance requirements and inventory availability. IRMCF371TR is recommended for applications requiring documented ROHS3 compliance. IRMCK371TR offers higher inventory availability when RoHS documentation is not required.
