Pressure Sensors Transducers Procurement Notes

Verify the specific interface configuration required for your application, as the part supports both I2C and SPI protocols. Confirm that the operating environment does not exceed the specified humidity sensitivity limits without proper protection. Ensure the PCB layout accommodates the 7 mm x 7 mm footprint and the 2 mm height constraint. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Pressure Sensors Transducers Selection Notes

Select this component when a low-profile, digitally interfaced gauge pressure sensor is required. It is suitable for applications needing direct microcontroller connection without analog-to-digital conversion stages. Consider the +/-40cmH2O range against your system's maximum expected pressure. Evaluate the SMD mounting style against mechanical stress requirements in the final assembly.

Pressure Sensors Transducers Part Context

This part belongs to the MMR920 series of MEMS pressure sensors from Mitsumi. The series focuses on providing accurate, small-footprint solutions for consumer and industrial electronics. The MMR920C04ARE specifically targets gauge pressure measurements with digital connectivity, distinguishing it from analog counterparts in the broader product line.

Pressure Sensors Transducers Replacement Considerations

The EASR920C04A-B2 is an evaluation kit for the MMR920C04A variant, not a direct functional replacement. No other direct substitute part numbers are confirmed in public documentation.
