Pressure Sensors Transducers Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance status during procurement. Confirm that the I2C address matches system requirements, as some variants may share addresses. Ensure the SOIC-14 footprint aligns with the PCB design guidelines provided in the official datasheet. Check moisture sensitivity level (MSL) ratings to determine storage and reflow soldering constraints before production.

Pressure Sensors Transducers Selection Notes

Select this component when a compact, digitally interfaced pressure solution is required for low-pressure environments up to 1 PSI. The NPA-700M-001G is suitable for designs prioritizing small form factors and simplified signal processing due to its integrated digital output. Consider the ±1.5% accuracy specification against application tolerances. Evaluate the -40°C to +125°C operating range to ensure compatibility with environmental conditions.

Pressure Sensors Transducers Part Context

This part belongs to the NPA-700 series of MEMS pressure sensors by Amphenol Advanced Sensors. The series offers various pressure ranges and output types, including analog and digital options. The NPA-700M-001G specifically targets low-pressure gauge applications with digital communication capabilities, distinguishing it from analog-output or higher-pressure variants within the same family.

Pressure Sensors Transducers Replacement Considerations

Direct substitutes within the NPA-700 series include models with different pressure ratings but identical packages and interfaces, such as NPA-700M-005G or NPA-700M-030G, if pressure range adjustments are acceptable. Verify pinout compatibility and software driver support when considering cross-model replacements.
