MPX53GP Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The MPX53GP is a vented gauge pressure sensor manufactured by NXP USA Inc., designed for board mount applications requiring measurement of 7.25 PSI (50 kPa) pressure ranges. This component features a Wheatstone Bridge output with 0 mV to 60 mV signal range at 3V supply, utilizing a 4-SIP through-hole module package with a barbed male tube port (0.19" / 4.93mm).

The MPX53GP is classified as obsolete. Locating equivalent or substitute components is necessary to support legacy system maintenance, design updates, or when original inventory becomes unavailable. The MPXM2053GS has been identified as a manufacturer-recommended substitute that maintains functional pressure measurement capability while offering improved specifications and active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPX53GP with the MPXM2053GS is based on the following critical parameters that must align for functional equivalence:

Pressure Measurement Parameters:

• Operating pressure: Both sensors measure 7.25 PSI (50 kPa)
• Pressure type: Both are vented gauge configurations
• Output type: Both utilize Wheatstone Bridge transduction
• Accuracy specification: Both maintain -0.6% to 0.4% accuracy

Environmental Parameters:

• Operating temperature range: Both function across -40°C to 125°C
• Compliance certifications: Both are ROHS3 compliant and REACH unaffected

Functional Differences: The MPXM2053GS introduces design improvements including higher supply voltage (10V to 16V versus 3V to 6V), increased output signal range (0 mV to 40 mV at 10V), temperature compensation, and surface mount packaging. These differences require circuit-level evaluation but do not prevent functional substitution for pressure measurement applications.

Parameter Comparison

Engineering Selection Recommendations

The MPXM2053GS is the manufacturer-recommended substitute for the obsolete MPX53GP. Both components maintain identical pressure measurement specifications (7.25 PSI vented gauge, Wheatstone Bridge output, -0.6% to 0.4% accuracy) and identical operating temperature ranges (-40°C to 125°C).

Selection of the MPXM2053GS requires evaluation of the following design considerations:

Supply Voltage: The MPXM2053GS requires 10V to 16V supply versus the MPX53GP's 3V to 6V. Existing power delivery circuits must be assessed for compatibility.

Mounting Architecture: The MPXM2053GS uses surface mount (5-SMD) technology versus the MPX53GP's through-hole (4-SIP) configuration. PCB layout and assembly processes require modification.

Mechanical Interface: Port size differs (0.12" barbless versus 0.19" barbed). Tubing connections and mechanical mounting must be re-evaluated.

Temperature Compensation: The MPXM2053GS includes temperature compensation, providing improved performance stability across the operating range.

Both components maintain ROHS3 compliance and REACH unaffected status, supporting regulatory requirements for new designs and legacy system updates.

Frequently Asked Questions (FAQ)

Q: Can the MPXM2053GS directly replace the MPX53GP without circuit modifications?

A: No. While both sensors measure identical pressure ranges with equivalent accuracy, the MPXM2053GS requires higher supply voltage (10V to 16V versus 3V to 6V) and produces different output signal levels (0 mV to 40 mV at 10V versus 0 mV to 60 mV at 3V). Signal conditioning and power delivery circuits require redesign.

Q: What are the mechanical compatibility issues between these sensors?

A: The MPX53GP uses a 0.19" barbed male tube port, while the MPXM2053GS uses a 0.12" barbless male tube port. Tubing connections, port adapters, and mechanical mounting brackets must be re-evaluated for the smaller port size and different connection style.

Q: Are both sensors suitable for the same pressure measurement applications?

A: Yes, both sensors are designed for vented gauge pressure measurement at 7.25 PSI (50 kPa) with identical accuracy specifications. Application suitability depends on circuit-level compatibility with the different supply voltage and output signal ranges.

Q: What is the significance of the temperature compensation feature in the MPXM2053GS?

A: Temperature compensation improves sensor output stability across the -40°C to 125°C operating range. This feature enhances measurement accuracy in applications experiencing significant temperature variations, though both sensors maintain the same specified accuracy range.

Q: Are there packaging or inventory considerations for the MPXM2053GS?

A: The MPXM2053GS is supplied in tube packaging and maintains active product status with 18,413 pieces in stock. The MPX53GP is obsolete with limited remaining inventory (1,920 pieces). The MPXM2053GS represents the current production alternative for new designs and ongoing system support.

Q: Do both sensors meet the same compliance standards?

A: Yes. Both the MPX53GP and MPXM2053GS are ROHS3 compliant and REACH unaffected, supporting equivalent regulatory requirements for industrial and commercial applications.
