ICM-42605
TDK InvenSense
Needs validationmedium risk
ICM-42605 is a close catalog IMU candidate, but pinout and firmware must be checked.
Best Alternatives to ICM-42688-P
ICM-42688-P replacements should be treated as IMU design candidates, not drop-in parts, until pinout and firmware behavior are verified.
AI replacement insight
Electrical riskmedium
VDD and ranges align for some candidates, but noise/ODR need checks.
Package riskmedium
14-pin LGA evidence exists for some, but pin maps are missing.
Firmware riskhigh
Registers, scale factors, FIFO and interrupts may differ.
Sourcing riskmedium
External candidates are not indexed in the catalog.
Can it be replaced directly?
No verified pin-compatible replacement is supported by the provided evidence.
Best replacement path
Use ICM-42605 as the best catalog candidate; review ICM-42688-V or ICM-42686-P after ingestion.
Main risk
Pinout and firmware/register compatibility are not verified.
