BMI160 Equivalent & Substitute Parts

Part Overview

The BMI160 is a 6-axis inertial measurement unit (IMU) manufactured by Bosch Sensortec, integrating accelerometer and gyroscope functionality in a compact 14-VFLGA surface mount package. The device supports both I2C and SPI communication protocols and operates across the industrial temperature range of -40°C to 85°C.

The BMI160 is currently discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. Substitute components must maintain compatibility with existing PCB layouts, communication interfaces, and thermal operating specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BMI160 is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Sensor Type: Must be 6-axis accelerometer and gyroscope combination
• Output Interface: Must support both I2C and SPI protocols
• Operating Temperature: Must span -40°C to 85°C minimum
• Package: Must be 14-VFLGA Module with 2.5x3 mm footprint
• Mounting: Must be Surface Mount technology
• Compliance: Must maintain ROHS3 and REACH Unaffected status

The LSM6DSOTR from STMicroelectronics meets all critical substitution criteria, providing functional and mechanical compatibility with BMI160 applications.

Parameter Comparison

Engineering Selection Recommendations

LSM6DSOTR as Primary Substitute:

The LSM6DSOTR is the qualified substitute for BMI160 applications. Both components share identical electrical interfaces (I2C/SPI), thermal operating range (-40°C to 85°C), and mechanical packaging (14-VFLGA, 2.5x3 mm). Both maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and consumer applications.

The LSM6DSOTR carries Active product status with 32,914 units in current inventory, ensuring supply chain continuity. The BMI160, being discontinued, presents long-term sourcing risk for new production and field replacements.

Both components are classified under identical ECCN (EAR99) and HTSUS codes (8542.39.0001), maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can LSM6DSOTR directly replace BMI160 in existing designs?

A: Yes. Both components feature identical 14-VFLGA packaging (2.5x3 mm), I2C/SPI interfaces, and -40°C to 85°C operating temperature range. PCB footprints and pinouts are compatible. Firmware integration requires validation of register maps and communication protocols specific to each manufacturer's implementation.

Q: What is the difference in Moisture Sensitivity Level between BMI160 and LSM6DSOTR?

A: BMI160 is rated MSL 1 (Unlimited moisture exposure), while LSM6DSOTR is rated MSL 3 (168 hours maximum). This affects storage and handling procedures. MSL 3 components require controlled humidity storage and have stricter reflow processing windows. Verify manufacturing and assembly processes accommodate MSL 3 requirements.

Q: Are both parts compliant with RoHS and REACH regulations?

A: Yes. Both BMI160 and LSM6DSOTR are ROHS3 Compliant and REACH Unaffected, meeting EU environmental and chemical safety standards.

Q: Why is BMI160 discontinued if LSM6DSOTR is available?

A: Product discontinuation decisions are manufacturer-driven and reflect market positioning, production priorities, and technology roadmap changes. LSM6DSOTR represents STMicroelectronics' active offering in the 6-axis IMU category and is the recommended path for new designs and production continuity.

Q: Do both parts support the same communication protocols?

A: Yes. Both BMI160 and LSM6DSOTR support I2C and SPI output interfaces. Register-level command structures and data formats differ between manufacturers and require firmware adaptation during integration.
