MPX4105A

Pressure Sensors Transducers Overview

The MPX4105A is an integrated silicon absolute pressure sensor manufactured by NXP USA Inc. It features a working pressure range of 2.18 PSI to 15.23 PSI (15 kPa to 105 kPa) and a maximum pressure of 58.02 PSI (400 kPa). The device provides an analog voltage output ranging from 0.3 V to 4.9 V, powered by a supply voltage between 4.85 V and 5.35 V. It offers ±1.8% accuracy and includes on-chip signal conditioning with temperature compensation. The component is housed in a 6-SIP module package with PC pin termination for through-hole mounting.

Pressure Sensors Transducers Procurement Notes

Verify current availability status as the MPX4105A is listed as obsolete or discontinued by the manufacturer. Confirm compatibility with existing PCB footprints and soldering profiles. Check for valid replacement part numbers from NXP or authorized distributors if production continuity is required. Ensure RoHS compliance documentation is available for regulatory adherence.

Pressure Sensors Transducers Selection Notes

Select this component when absolute pressure measurement within the 15 kPa to 105 kPa range is required. Consider the 6-SIP package for through-hole assembly needs. Evaluate the ±1.8% accuracy specification against system tolerance requirements. Verify that the analog voltage output range aligns with the input specifications of the downstream microcontroller or ADC.

Pressure Sensors Transducers Part Context

The MPX4105A belongs to the MPX41 series of pressure sensors from NXP. These sensors are designed for applications requiring reliable pressure detection with minimal external circuitry. The series typically integrates the piezoresistive element and signal processing electronics into a single silicon die, providing a compact solution for industrial and automotive environments.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitute part numbers are not explicitly provided in the source data. Consult NXP official documentation for direct replacements or cross-reference lists due to the obsolete status.
