ICM-20601 Equivalent & Substitute Parts

Part Overview

The ICM-20601 is a 6-axis inertial measurement unit (IMU) integrating accelerometer, gyroscope, and temperature sensor functionality with I2C and SPI digital output interfaces. Manufactured by TDK InvenSense, this component is packaged in a 16-WFLGA module format suitable for surface mount applications. The ICM-20601 has reached obsolete product status, necessitating identification of functionally equivalent alternatives for ongoing system support and new design considerations.

Substitute Part Grouping Explanation

Substitute parts for the ICM-20601 are identified based on functional equivalence across the following critical parameters:

• Sensor functionality: 6-axis accelerometer, gyroscope, and temperature measurement capability
• Digital communication protocols: I2C and SPI interface support
• Operating temperature range: -40°C to 85°C
• Environmental compliance: ROHS3 and REACH compliance status
• Moisture sensitivity classification: MSL 3 (168 Hours)

The ICM-42670-P represents the manufacturer-recommended primary substitute with active product status and enhanced ECCN classification (EAR99). The ICM-20602 provides an alternative with identical package specifications but carries a "Not For New Designs" designation.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the ICM-20601, the ICM-42670-P is the primary substitute option. This part maintains full functional equivalence across sensor capabilities, communication protocols, and environmental specifications while carrying active product status. The ICM-42670-P features improved export classification (EAR99 versus 7A994), supporting broader supply chain flexibility.

The ICM-20602 provides an alternative substitute with identical package and pin configuration to the ICM-20601, enabling direct board-level replacement without layout modifications. However, its "Not For New Designs" status restricts application to legacy system support and maintenance scenarios.

Both substitute parts maintain ROHS3 compliance and identical moisture sensitivity specifications, ensuring compatibility with existing assembly and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the ICM-42670-P directly replace the ICM-20601 on existing PCBs?

A: The ICM-42670-P uses a different package format (14-VFLGA versus 16-WFLGA), requiring PCB layout modifications. Pin-to-pin compatibility must be verified against detailed datasheets before implementation.

Q: Is the ICM-20602 suitable for new product designs?

A: No. The ICM-20602 carries "Not For New Designs" status and should be reserved for legacy system maintenance only. The ICM-42670-P is the recommended choice for new applications.

Q: Do all substitute parts support the same communication protocols?

A: Yes. The ICM-20601, ICM-42670-P, and ICM-20602 all support I2C and SPI interfaces with identical operating temperature ranges (-40°C to 85°C).

Q: What is the significance of the ECCN classification difference?

A: The ICM-42670-P carries EAR99 classification, which generally permits broader export flexibility compared to the 7A994 classification of the ICM-20601 and ICM-20602. Export requirements vary by destination and application.

Q: Are moisture sensitivity and RoHS compliance identical across all three parts?

A: Yes. All three parts are ROHS3 compliant with MSL 3 (168 Hours) moisture sensitivity classification, ensuring compatibility with standard assembly and storage procedures.
