MPU-9250 Equivalent & Substitute Parts

Part Overview

The MPU-9250 is a 9-axis inertial measurement unit (IMU) combining accelerometer, gyroscope, and magnetometer functionality. This part is classified as obsolete and no longer in active production. Finding equivalent substitute components is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing product development or maintenance cycles where the original MPU-9250 is unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPU-9250 is based on the following critical parameters:

• Sensor Configuration: Both parts must provide 9-axis sensing (accelerometer, gyroscope, magnetometer)
• Communication Interface: Both parts must support I2C and/or SPI protocols for system integration
• Manufacturer Continuity: TDK InvenSense maintains the product line, ensuring design consistency and technical support
• Package Compatibility: Physical form factor and pin configuration must accommodate existing PCB layouts
• Product Status: Active production status ensures long-term availability and supply chain stability

The ICM-20948 meets all substitution criteria as a direct equivalent from the same manufacturer, offering enhanced specifications and active product status.

Engineering Selection Recommendations

The ICM-20948 is the designated manufacturer substitute for the obsolete MPU-9250. Selection is based on:

• Product Status: The ICM-20948 maintains active production status, ensuring continuous availability and technical support from TDK InvenSense
• Regulatory Compliance: The ICM-20948 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements
• Moisture Sensitivity: The ICM-20948 offers improved MSL rating (1 vs. 3), reducing handling and storage constraints during manufacturing
• Manufacturer Continuity: Both components are from TDK InvenSense, ensuring consistent design philosophy, firmware compatibility, and technical documentation

Frequently Asked Questions (FAQ)

Q: Can the ICM-20948 directly replace the MPU-9250 in existing designs?

A: The ICM-20948 provides equivalent 9-axis sensor functionality (accelerometer, gyroscope, magnetometer) with I2C and SPI communication interfaces. Physical package and pin configuration must be verified against your PCB layout to confirm mechanical compatibility.

Q: What is the difference in Moisture Sensitivity Level (MSL) between these parts?

A: The MPU-9250 has MSL 3 (168 hours), while the ICM-20948 has MSL 1 (unlimited). MSL 1 indicates superior moisture resistance and reduced baking requirements during manufacturing and storage, lowering production complexity.

Q: Why is the MPU-9250 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. TDK InvenSense has transitioned the product line to the ICM-20948, which offers enhanced specifications and improved compliance certifications.

Q: Are there any firmware or software compatibility considerations?

A: Both parts share the same manufacturer and sensor architecture. Register maps and communication protocols are designed for compatibility, but firmware validation is required for your specific application.

Q: What packaging options are available for the ICM-20948?

A: The ICM-20948 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats in a 24-QFN (3x3) surface mount package.
