Best Alternatives to QMA6100P

Package: LGA-12QSTTransducers3-AxisResolution: 14-bitInterface: I2C, SPISupply Voltage: 1.71V ~ 3.6VOperating Temperature: -40°C ~ +85°C

QMA6100P is a 3-axis LGA-12 I2C/SPI accelerometer. ST LGA-12 parts are possible alternates, but no pin-compatible replacement is confirmed.

AI replacement insight

Electrical riskmedium

Voltage and bus match; modes may differ.

Package riskmedium

LGA-12 matches, dimensions need check.

Firmware riskhigh

Register maps may differ.

Sourcing risklow

Main ST candidates are catalog matched.

Can it be replaced directly?

No verified pin-compatible replacement is proven from the supplied data.

Best replacement path

Start with LIS2DW12TR, then verify pinout, land pattern, register map, and power modes.

Main risk

Pinout and firmware compatibility are not verified.
