NXP Semiconductors MPX5010DP

Overview

MPX5010DP from NXP Semiconductors is a differential silicon piezoresistive pressure sensor with on-chip signal conditioning, temperature compensation, and factory calibration. It delivers a ratiometric analog output (0.2–4.925 V) over a 0–10 kPa pressure range at 5 V supply, with ±5.0% full-scale span accuracy across 0° to 85°C, and is packaged in a durable epoxy unibody SOT1756-1 (Case 867C-05) for industrial fluid sensing applications.

For engineers reviewing the MPX5010DP datasheet, MPX5010DP pinout, MPX5010DP application, or MPX5010DP equivalent, this page provides verified technical context, validated pin functions, real-world use scenarios in HVAC and medical devices, and two confirmed alternative parts with documented functional and packaging differences.

Technical Context

The MPX5010DP integrates a patented silicon shear-stress strain gauge with thin-film metallization and bipolar signal conditioning circuitry on a single monolithic die. Its architecture includes dual gain stages, ground-reference shift circuitry, and on-chip temperature compensation optimized for –40° to +125°C operation.

It operates as a ratiometric device: output voltage scales linearly with supply voltage (4.75–5.25 V), and its transfer function is defined as V_OUT = V_S × (0.09 × P + 0.04) ± 5.0% VFSS. Pins 4–6 are no-connects, confirming a 3-terminal active interface (V_OUT, GND, V_S) within a 6-pin unibody package.

Key Specifications

Pinout & Package

SOT1756-1 is a 6-terminal unibody surface-mount package (17.78 mm × 29.48 mm × 10.67 mm) with axial pressure port, epoxy encapsulation, and thermoplastic (PPS) housing. Pin 1 is marked on the top-side silkscreen; P1 (pressure side) is identified by part marking per Table 7.

The following parts are listed as comparable options for similar differential pressure sensing applications.

Compared with MPX5010GP and MPXV5010DP, the MPX5010DP uniquely combines differential porting, axial tubing compatibility, and unibody mechanical robustness - making it the only option among the three qualified for direct integration into medical respiratory and appliance liquid-level systems per AN1950.

FAQ

What is the maximum pressure rating for MPX5010DP?

The MPX5010DP has a maximum pressure rating of 40 kPa (P1 > P2), as specified in Table 5 of the Rev. 14 datasheet. This limiting value defines the absolute upper bound before permanent damage may occur; the recommended operating range remains 0–10 kPa. Exceeding 40 kPa voids reliability guarantees and risks diaphragm rupture or calibration drift. Always implement mechanical pressure limiting upstream when deploying MPX5010DP in variable-pressure environments.

Does MPX5010DP require external calibration?

No, MPX5010DP does not require external calibration. It ships fully calibrated from the factory with on-chip temperature compensation covering –40° to +125°C. The device's ±5.0% VFSS accuracy over 0° to 85°C is achieved using integrated thin-film resistors and bipolar signal conditioning - no trimming resistors, EEPROM, or software correction is needed. Users only need to apply proper decoupling (1.0 µF + 0.01 µF) per Figure 11 to maintain spec compliance for MPX5010DP.

Can MPX5010DP be used with a 3.3 V supply?

No, MPX5010DP is not specified for 3.3 V operation. Its recommended supply voltage is strictly 4.75–5.25 V DC (Table 6), and the ratiometric transfer function V_OUT = V_S × (0.09 × P + 0.04) assumes V_S = 5.0 V. Operating below 4.75 V risks output saturation, reduced signal-to-noise ratio, and failure to meet ±5.0% VFSS accuracy. For 3.3 V systems, consider NXP's MP3V5004 or MPXV5004 series - not MPX5010DP.

What is the meaning of "N.C." on pins 4–6 of MPX5010DP?

"N.C." stands for "No Connect" - these pins (4, 5, and 6) have no internal electrical connection to the die or signal chain of MPX5010DP. They are physically present in the SOT1756-1 package for mechanical stability and handling but must remain unconnected in the PCB layout. Neither grounding nor pulling them to V_S is permitted; doing so may compromise package integrity or introduce noise. This is explicitly confirmed in Figure 2 and Table 3 of the MPX5010DP datasheet.

Is MPX5010DP compatible with wet media such as water or cleaning fluids?

MPX5010DP is qualified for dry air only per Section 9 of the datasheet. Its fluorosilicone gel isolates the die but is not rated for direct contact with water, detergents, or solvents. In washing machine applications (Reference AN1950), it measures hydrostatic pressure indirectly via an air-filled tube - the sensor itself remains dry. For direct wet-media exposure, NXP recommends MPVZ5010 series variants with media-resistant gel; MPX5010DP must be deployed in dry-side configurations to ensure long-term reliability.
