MPX4250A

Pressure Sensors Transducers Overview

The MPX4250A is an absolute pressure sensor designed for manifold absolute pressure (MAP) sensing in engine control systems. It measures pressures ranging from 20 kPa to 250 kPa with a typical accuracy of ±1.5%. The device provides an analog voltage output between 0.2 V and 4.9 V, powered by a supply voltage of 4.85 V to 5.35 V. It operates within a temperature range of -40°C to 125°C and features temperature compensation. The component is available in an 8-SMD module package without ports.

Pressure Sensors Transducers Procurement Notes

Verify the specific suffix variant required, as the base part number may correspond to different package configurations such as SMD modules or ported versions. Confirm availability status, as this series may be discontinued or subject to last-time-buy constraints. Ensure the selected variant matches the required port style and mounting type for the target PCB design. Cross-reference official NXP documentation for the exact ordering code corresponding to the desired physical interface.

Pressure Sensors Transducers Selection Notes

Select the appropriate suffix variant based on the required mechanical interface, such as ported or non-ported configurations. Consider the operating temperature range requirements, ensuring compatibility with the -40°C to 125°C specification. Verify that the analog voltage output range aligns with the input requirements of the downstream microcontroller or signal conditioning circuitry. Evaluate the need for temperature compensation if operating outside standard calibrated ranges.

Pressure Sensors Transducers Part Context

The MPX4250A belongs to the MPX4250A/MPXA4250A series of silicon pressure sensors manufactured by NXP USA Inc. This family includes variants like MPXA4250A6T1 and MPXA4250AC6T1, which differ primarily in packaging and port styles. These sensors are engineered for robust performance in automotive environments, providing reliable absolute pressure measurements for critical engine management functions.

Pressure Sensors Transducers Replacement Considerations

Direct replacements include other members of the MPX4250A series, such as MPXA4250A6T1 or MPXA4250AC6T1, depending on the required package and port configuration. Verify pinout compatibility and electrical specifications before substitution. Note that some variants may be discontinued; consult current NXP product status for availability.
