MPX53DP Equivalent & Substitute Parts

Part Overview

The MPX53DP is a differential pressure sensor manufactured by NXP Semiconductors with a 7.25 PSI (50 kPa) operating range. This component features a Wheatstone Bridge output with 0 mV to 60 mV signal range at 3V supply, housed in a 4-SIP through-hole module with barbed male tube ports (0.19" / 4.93mm). The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

The MPXM2053GS is identified as a manufacturer-recommended substitute for the MPX53DP. Substitution eligibility is determined by the following critical parameters:

Matching Parameters:

Operating Pressure: Both sensors operate at 7.25 PSI (50 kPa)
Output Type: Both use Wheatstone Bridge transduction
Accuracy: Both maintain -0.6% ~ 0.4% accuracy specification
Operating Temperature Range: Both function across -40°C ~ 125°C
Compliance: Both are ROHS3 compliant and REACH unaffected

Differing Parameters:

Pressure Type: MPX53DP is differential; MPXM2053GS is vented gauge
Supply Voltage: MPX53DP requires 3V ~ 6V; MPXM2053GS requires 10V ~ 16V
Output Range: MPX53DP outputs 0 mV ~ 60 mV; MPXM2053GS outputs 0 mV ~ 40 mV
Port Size: MPX53DP uses 0.19" (4.93mm) barbed ports; MPXM2053GS uses 0.12" (2.97mm) barbless ports
Mounting: MPX53DP is through-hole; MPXM2053GS is surface mount
Package: MPX53DP is 4-SIP; MPXM2053GS is 5-SMD

Engineering Selection Recommendations

The MPXM2053GS is an active product from NXP USA Inc. and carries ROHS3 compliance and REACH unaffected status, matching the regulatory posture of the obsolete MPX53DP. Both sensors share identical operating pressure (7.25 PSI / 50 kPa), accuracy specification (-0.6% ~ 0.4%), and temperature range (-40°C ~ 125°C).

Selection of MPXM2053GS requires accommodation of the following differences: pressure type transition from differential to vented gauge, supply voltage increase from 3V–6V to 10V–16V, output signal reduction from 0–60 mV to 0–40 mV, port size reduction from 0.19" to 0.12" diameter, and mounting architecture change from through-hole to surface mount. These differences necessitate circuit redesign and mechanical interface modification.

Frequently Asked Questions (FAQ)

Q: Can MPXM2053GS directly replace MPX53DP in existing designs?

A: No. While both sensors operate at 7.25 PSI with identical accuracy and temperature range, they differ in pressure type (differential vs. vented gauge), supply voltage requirements (3V–6V vs. 10V–16V), output signal levels (0–60 mV vs. 0–40 mV), port dimensions (0.19" vs. 0.12"), and mounting technology (through-hole vs. surface mount). Circuit and mechanical redesign is required.

Q: What is the significance of the pressure type difference?

A: MPX53DP measures pressure differential between two independent ports. MPXM2053GS measures gauge pressure (differential between a single port and atmospheric reference). Application requirements determine which pressure type is appropriate.

Q: Are there compatibility issues with the port size reduction?

A: Yes. MPX53DP uses 0.19" (4.93mm) barbed male tube ports; MPXM2053GS uses 0.12" (2.97mm) barbless male tube ports. Tubing and connector specifications must be updated accordingly.

Q: How does the supply voltage difference affect system design?

A: MPX53DP operates on 3V–6V supply; MPXM2053GS requires 10V–16V. Power supply architecture and signal conditioning circuits must be redesigned to accommodate the higher voltage requirement and different output signal range (0–40 mV vs. 0–60 mV).

Q: What mounting considerations apply to the transition?

A: MPX53DP is a through-hole component with PC pin termination; MPXM2053GS is a surface-mount component with gull-wing termination. PCB layout, assembly process, and soldering specifications require modification.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both MPX53DP and MPXM2053GS are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
