Interface Compatibility: Matching digital output protocols (I2C and SPI support)

Thermal Operating Range: Identical temperature specification (-40°C ~ 85°C)

Regulatory Compliance: Equivalent RoHS3 and REACH status

Packaging Category: 24-pin QFN surface mount configuration with exposed pad

Manufacturer Designation: TDK InvenSense manufacturer lineage

The ICM-20689 meets all substitution criteria as a manufacturer-recommended equivalent part within the InvenSense motion sensor product family.

Parameter Comparison

Engineering Selection Recommendations

The ICM-20689 is the manufacturer-designated substitute for the ICM-20649. Both components share identical functional specifications, electrical interfaces, thermal operating range, and regulatory compliance status. The primary physical distinction is the supplier device package footprint: the ICM-20649 uses a 3x3mm QFN package, while the ICM-20689 uses a 4x4mm QFN package.

Selection between these parts depends on printed circuit board layout constraints and available mounting area. Both components maintain ROHS3 compliance and REACH unaffected status, supporting equivalent environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ICM-20689 be used as a direct replacement for the ICM-20649?

A: The ICM-20689 provides functional and electrical equivalence. The primary consideration is package footprint compatibility. The ICM-20689 uses a larger 4x4mm QFN package compared to the ICM-20649's 3x3mm package. PCB layout modifications may be required.

Q: Are the I2C and SPI interfaces identical between these parts?

A: Both the ICM-20649 and ICM-20689 support I2C and SPI digital output protocols. Interface compatibility is maintained across both components.

Q: Do both parts operate across the same temperature range?

A: Yes. Both the ICM-20649 and ICM-20689 operate across the -40°C to 85°C temperature range.

Q: What is the significance of the different QFN package sizes?

A: The ICM-20649 uses a 3x3mm QFN footprint, while the ICM-20689 uses a 4x4mm QFN footprint. This affects PCB land pattern design and available mounting area. Designs with space constraints may require evaluation of layout feasibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ICM-20649 and ICM-20689 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the moisture sensitivity level for these components?

A: Both parts carry MSL 3 rating with a 168-hour floor life specification, requiring equivalent moisture control during storage and handling.
