Product details
Overview
MPX2102DP from NXP Semiconductors (formerly Freescale) is a differential silicon piezoresistive pressure sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range. It features laser-trimmed span/offset calibration, ±0.1%VFSS pressure hysteresis, and operates from −40°C to +125°C. Used in medical diagnostics, pump control, and robotics for precise differential pressure measurement.
For engineers reviewing the MPX2102DP datasheet, MPX2102DP pinout, MPX2102DP application, or MPX2102DP equivalent, key selection criteria include its unibody Case 344C package, ratiometric 10 V excitation, 1 ms response time, differential port configuration, and compatibility with dry air media only.
Technical Context
The MPX2102DP integrates a monolithic silicon diaphragm with embedded strain gauges and thin-film resistor networks for direct voltage output proportional to applied differential pressure (P1 > P2). Its on-chip temperature compensation circuitry corrects both full-scale span and offset over 0°C to +85°C.
It uses an end-point linearity method (±0.4%VFSS for MPX2102D series), exhibits 0.4 mV/kPa sensitivity, and maintains ±0.5%VFSS offset stability after 1000-hour pulsed pressure/temperature cycling. Input and output impedances are 1–2.5 kΩ and 1.4–3 kΩ respectively.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa differential (P1 > P2); supports vacuum on P2 side relative to P1. |
| Full Scale Output | 40 mV typical at 10 V supply; ratiometric - scales linearly with supply voltage. |
| Supply Voltage | 10 VDC nominal (6–16 VDC operating range); self-heating error increases above 10 V. |
| Response Time | 1.0 ms (10% to 90%); enables real-time monitoring in fast-cycling pneumatic systems. |
| Linearity Error | ±0.4%VFSS (end-point method); ensures predictable transfer function across full scale. |
| Temperature Range | −40°C to +125°C operating; compensated performance specified 0°C to +85°C. |
| Pressure Hysteresis | ±0.1%VFSS (0–100 kPa); critical for repeatability in bidirectional pressure actuation. |
Pinout & Package
MPX2102DP uses the unibody Case 344C package: stainless steel cap, dual-port configuration (P1 = positive pressure side, P2 = vacuum side), with marking-side identification per Table 3. Dimensions: 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Ground | Reference node for output and supply; connects to system common ground plane. |
| Pin 2 | + Output (VOUT+) | High-side analog output; voltage rises with increasing P1–P2 differential pressure. |
| Pin 3 | + Supply (VS) | Excitation input; must be stable DC source (6–16 V); output scales ratiometrically. |
| Pin 4 | − Output (VOUT−) | Low-side analog output; forms differential pair with Pin 2 for noise-rejecting measurements. |
Key Features
| Feature | Design Value |
|---|---|
| Differential pressure sensing | Measures pressure difference between two ports (P1 and P2); enables flow, level, and leak detection without absolute reference. |
| On-chip temperature compensation | Reduces span and offset drift over 0°C to +85°C - eliminates need for external compensation circuitry. |
| Laser-trimmed calibration | Ensures factory-set accuracy: ±0.4%VFSS linearity and ±0.1%VFSS hysteresis without user trimming. |
| Ratiometric output | Output voltage scales linearly with supply voltage - simplifies ADC interfacing when using same supply for sensor and converter. |
| Dual-port unibody construction | Robust Case 344C mechanical design with silicone gel isolation protects die while transmitting pressure signal reliably. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV2102GP | Small-outline package (Case 1369), single-port gauge configuration; 0–100 kPa gauge range, not differential. | Requires ambient reference; unsuitable for true differential or sealed-chamber use cases. | Select MPXV2102GP only when ambient-referenced pressure (not P1–P2) suffices and PCB space is constrained. |
| MPXM2102D | MPAK package (Case 1320), same 0–100 kPa differential range, but higher input impedance (min 1 kΩ vs 1–2.5 kΩ) and no specified hysteresis value. | Lacks published pressure hysteresis spec; less validated for high-cycle repeatability than MPX2102DP. | Choose MPXM2102D for surface-mount automation compatibility, but verify hysteresis in final application. |
Compared with MPXV2102GP and MPXM2102D, the MPX2102DP provides verified ±0.1%VFSS pressure hysteresis, dual-port differential architecture, and Case 344C mechanical robustness - making it preferred for mission-critical differential measurement where repeatability and port flexibility are essential.

FAQ
What is the pressure type and range supported by the MPX2102DP?
The MPX2102DP is a differential pressure sensor with a rated range of 0–100 kPa (0–14.5 psi) for P1 > P2. It is not rated for absolute or gauge operation. Its Case 344C package has two ports: P1 (marked side) accepts positive pressure, and P2 (unmarked side) accepts vacuum or lower pressure - enabling true differential measurement without external reference.
Does the MPX2102DP require external temperature compensation?
No, the MPX2102DP includes on-chip temperature compensation circuitry that corrects both full-scale span and offset over 0°C to +85°C. This eliminates the need for external thermistors or digital compensation algorithms in most applications. The datasheet specifies TCVOFF ≤ ±1.0 mV and TCVFSS ≤ ±2.0%VFSS across that range - verified by factory calibration.
What is the recommended supply voltage and current draw for the MPX2102DP?
The MPX2102DP operates with a supply voltage of 6–16 VDC, with 10 VDC as the nominal excitation. At 10 V, typical supply current is 6.0 mA. Operating above 10 V may induce self-heating errors; below 6 V risks insufficient output swing. The device is ratiometric - output voltage scales linearly with supply, simplifying ADC reference design.
Can the MPX2102DP be used with fluids other than dry air?
No - the MPX2102DP's qualification and reliability testing were performed exclusively with dry air as the pressure medium. Exposure to moisture, oils, or corrosive gases may degrade silicone gel encapsulation, wire bonds, or the silicon diaphragm. For non-dry-air media, consult NXP's factory for compatibility validation before deployment; standard warranty does not cover media-related failure.
What is the meaning of "Case 344C" in the MPX2102DP ordering code?
Case 344C denotes the unibody package variant of the MPX2102DP: stainless steel cap, dual-port configuration, with P1 identified by the side bearing the part marking. Its dimensions are 29.08–29.85 mm × 17.40–18.16 mm × 7.75–8.26 mm. This mechanical form factor differs from Case 344B (single-port gauge) and Case 344D (gauge/vacuum combo), and is not interchangeable without redesign.
