MPX12GP Equivalent & Substitute Parts

Part Overview

The MPX12GP is a vented gauge pressure sensor manufactured by NXP USA Inc., designed for board mount applications requiring low-pressure measurement. This 4-SIP module sensor outputs 0 mV to 55 mV across a 3V supply and operates across an extended temperature range of -40°C to 125°C. The part is currently obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the obsolete MPX12GP is based on the following critical parameters that must remain compatible:

Pressure Measurement Range: Operating pressure of 1.45 PSI (10 kPa) and maximum pressure rating of 10.88 PSI (75 kPa)
Output Interface: Wheatstone Bridge output type with 3V to 6V supply voltage compatibility
Physical Interface: Male barbed port at 0.19" (4.93 mm) tube size for pneumatic connection
Electrical Termination: PC Pin termination for through-hole mounting on 4-SIP module package
Environmental Specifications: Operating temperature range of -40°C to 125°C
Regulatory Compliance: ROHS3 compliance and REACH unaffected status

The MPX10DP is identified as a manufacturer-recommended substitute. While it operates at the same pressure range and maintains compatible electrical supply and termination characteristics, it differs in pressure measurement type (differential versus vented gauge) and output sensitivity (35 mV versus 55 mV at 3V).

Engineering Selection Recommendations

The MPX10DP is the manufacturer-recommended substitute for the obsolete MPX12GP. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. The MPX10DP is currently in active production status, providing supply chain stability compared to the obsolete MPX12GP.

Key differences require circuit-level evaluation: the MPX10DP operates as a differential pressure sensor with dual ports, whereas the MPX12GP is a vented gauge sensor with single port. The MPX10DP provides superior accuracy (±1% versus ±5%) but with reduced output sensitivity (35 mV versus 55 mV at 3V supply). Signal conditioning circuits must account for the lower output voltage range of the MPX10DP. The dual-port configuration of the MPX10DP requires appropriate reference pressure connection management in applications originally designed for vented gauge operation.

Frequently Asked Questions (FAQ)

Q: Can the MPX10DP directly replace the MPX12GP without circuit modifications?

A: Physical and electrical interfaces are compatible (PC Pin termination, 4-SIP package, 3V-6V supply voltage, identical pressure range). However, the pressure measurement type differs (differential versus vented gauge) and output sensitivity is lower (35 mV versus 55 mV). Signal conditioning circuits must be evaluated for compatibility with the reduced output range.

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

A: The MPX12GP (vented gauge) measures pressure relative to atmospheric pressure through a single vent port. The MPX10DP (differential) measures the pressure difference between two independent ports. Applications originally designed for vented gauge operation require reference pressure management when transitioning to differential measurement.

Q: Are there packaging or inventory considerations for the MPX10DP?

A: The MPX10DP is supplied in Tray packaging with 6,340 pieces currently in stock. The MPX12GP, being obsolete, has limited availability. The MPX10DP's active product status ensures ongoing supply chain support.

Q: How does the accuracy difference affect system performance?

A: The MPX10DP provides ±1% accuracy compared to the MPX12GP's ±5% accuracy. This represents a fourfold improvement in measurement precision. System calibration and signal processing may require adjustment to leverage this improved accuracy specification.

Q: Are both parts compliant with current regulatory requirements?

A: Both the MPX12GP and MPX10DP are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.
