MPX4100A

Pressure Sensors Transducers Overview

The MPX4100A is an integrated absolute pressure sensor designed for manifold absolute pressure (MAP) sensing in engine control applications. It operates within a pressure range of 2.9 PSI to 15.23 PSI (20 kPa to 105 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 features temperature compensation and maintains an accuracy of ±1.8%. The sensor is housed in a 6-SIP module package with through-hole PC pin termination, suitable for board mounting.

Pressure Sensors Transducers Procurement Notes

Verify component authenticity due to the part's end-of-life status. Confirm that the specific package variant matches the design requirements, as the MPX4100 series includes both SIP and SMD configurations. Ensure the selected substitute supports the required operating temperature range and voltage specifications. Check for RoHS compliance documentation if environmental regulations apply to the final assembly.

Pressure Sensors Transducers Selection Notes

Select this component for applications requiring absolute pressure measurement in the 20 kPa to 105 kPa range. The 6-SIP package is appropriate for through-hole assembly processes. Consider the ±1.8% accuracy specification against system tolerance requirements. Verify that the analog output interface aligns with the input capabilities of the downstream signal conditioning or ADC circuitry.

Pressure Sensors Transducers Part Context

The MPX4100A belongs to the MPX41xxA series of integrated pressure sensors originally developed by Freescale Semiconductor and later acquired by NXP. This family is widely recognized in automotive industries for robust performance under harsh conditions. The device represents a mature MEMS technology platform, offering a balance of precision and cost-effectiveness for mass-produced electronic control modules.

Pressure Sensors Transducers Replacement Considerations

Public confirmed substitutes include MPX4100AP and MPXAZ4100AC6U. Note that MPX4100AP utilizes a 6-SIP module similar to the original, while MPXAZ4100AC6U uses an 8-SMD鸥翼 package. Package differences require PCB layout modifications. Verify that all candidates maintain the same pressure range and output characteristics.
