Pressure Sensors Transducers Procurement Notes

Verify that the specific suffix '005D' corresponds to the 5PSI differential pressure rating and I2C interface before ordering. Confirm that the 3.135V to 3.465V supply voltage requirement aligns with the target system's power rails. Ensure the 14-SOIC package dimensions and dual barbed port orientation fit the mechanical constraints of the printed circuit board layout. Check for RoHS compliance status if required by project specifications.

Pressure Sensors Transducers Selection Notes

Select this model when a digital I2C interface is preferred over analog outputs to simplify microcontroller interfacing. Choose the NPA-730B-005D for applications requiring precise differential pressure measurement up to 5PSI with high resolution. Consider this part for designs needing integrated signal conditioning and temperature compensation without external components. Evaluate the 14-SOIC package size against available board space compared to other sensor form factors.

Pressure Sensors Transducers Part Context

This component belongs to the NPA-730 series of MEMS pressure sensors manufactured by Amphenol Advanced Sensors under the NovaSensor brand. The series focuses on digital output solutions for compact electronic systems. The NPA-730B variant specifically denotes the differential pressure type with barbed ports. This family provides a modern alternative to traditional analog pressure transducers by integrating signal processing directly into the sensor module.

Pressure Sensors Transducers Replacement Considerations

NPA-730B-001G: Offers similar digital I2C functionality but with a lower 1PSI working pressure range. NPA-730N-005D: Provides equivalent 5PSI differential sensing and I2C output but lacks physical ports, requiring manifold integration.
