MPX2102DP Equivalent & Substitute Parts

Part Overview

The MPX2102DP is a differential pressure sensor manufactured by NXP USA Inc., designed for board mount applications with a 14.5 PSI (100 kPa) operating pressure range. The device features a Wheatstone Bridge output with 0 mV to 40 mV (10V) signal range and operates across -40°C to 125°C. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MPX2102DP requires evaluation based on the following critical parameters that define functional equivalence:

Electrical Compatibility:

• Output Type: Wheatstone Bridge configuration
• Output Range: 0 mV ~ 40 mV (10V)
• Supply Voltage: 10V ~ 16V
• Accuracy: -0.6% ~ 0.4%
• Operating Temperature: -40°C ~ 125°C

Mechanical & Application Compatibility:

• Pressure measurement capability within system requirements
• Temperature compensation feature
• RoHS3 compliance for regulatory alignment

The MPXM2053GS is identified as a substitute part from the same manufacturer (NXP USA Inc.) with matching electrical specifications. However, critical differences exist in pressure type, port configuration, and mounting technology that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The MPXM2053GS shares core electrical specifications with the MPX2102DP, including identical output range, supply voltage, accuracy, and operating temperature range. Both devices feature temperature compensation and maintain ROHS3 compliance.

However, substitution requires careful application analysis due to the following differences:

Pressure Measurement Differences: The MPX2102DP operates at 14.5 PSI differential pressure, while the MPXM2053GS operates at 7.25 PSI vented gauge pressure. These represent different measurement principles and pressure ranges. The MPXM2053GS maximum pressure rating (29.01 PSI) is lower than the MPX2102DP (58.02 PSI).

Mechanical Integration: The MPX2102DP uses through-hole mounting with PC pins and barbed ports (0.19" diameter). The MPXM2053GS uses surface-mount technology with gull-wing termination and smaller barbless ports (0.12" diameter). PCB layout, connector compatibility, and tubing interfaces require redesign.

Product Status: The MPXM2053GS is active production, ensuring long-term availability and supply chain stability compared to the obsolete MPX2102DP.

Substitution is viable only when the application can accommodate vented gauge pressure measurement at the lower 7.25 PSI operating range and surface-mount integration is feasible.

Frequently Asked Questions (FAQ)

Q: Can the MPXM2053GS directly replace the MPX2102DP in existing designs?

A: Direct replacement is not possible without design modifications. The MPXM2053GS requires PCB redesign for surface-mount placement, connector interface changes, and tubing reconfiguration due to different port sizes and styles. Additionally, the pressure measurement type differs (differential vs. vented gauge), which may affect system calibration and measurement accuracy.

Q: What is the difference between differential and vented gauge pressure measurement?

A: Differential pressure sensors measure the pressure difference between two independent ports. Vented gauge sensors measure pressure relative to atmospheric pressure through a vent port. These represent fundamentally different measurement principles and are not interchangeable without system-level changes.

Q: Are the electrical outputs compatible?

A: Yes. Both devices provide identical Wheatstone Bridge output in the 0 mV to 40 mV range at 10V supply, with matching accuracy specifications and operating temperature ranges. Signal conditioning and amplification circuits designed for the MPX2102DP will function with the MPXM2053GS output without modification.

Q: What are the packaging and mounting implications?

A: The MPX2102DP uses through-hole 4-SIP packaging with PC pin termination for traditional PCB assembly. The MPXM2053GS uses surface-mount 5-SMD packaging with gull-wing leads, requiring modern SMD assembly equipment and different PCB footprints. Port connector changes from 0.19" barbed to 0.12" barbless tubing interfaces also require mechanical redesign.

Q: Does the lower pressure rating of the MPXM2053GS affect compatibility?

A: Yes. The MPXM2053GS maximum pressure is 29.01 PSI compared to 58.02 PSI for the MPX2102DP. If the application requires measurement or overpressure protection above 29.01 PSI, the MPXM2053GS is unsuitable. System pressure specifications must be verified before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both the MPX2102DP and MPXM2053GS are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and use.
