Product details
Overview
MPX2102D from Freescale Semiconductor is a silicon piezoresistive differential pressure sensor with on-chip temperature compensation, delivering 40 mV full-scale output at 10 V supply across 0–100 kPa range, used in medical diagnostics and pump control systems where precise low-pressure differential measurement is required.
For engineers reviewing the MPX2102D datasheet, MPX2102D pinout, MPX2102D application, or MPX2102D equivalent, this page provides verified technical context, pin-level circuit roles, real-world use scenarios, and validated alternative options for industrial and embedded pressure-sensing designs.
Technical Context
The MPX2102D implements a monolithic silicon diaphragm with integrated strain gauge and thin-film resistor network, laser-trimmed for span and offset calibration. It operates ratiometrically with 10 V ±6 V excitation and exhibits 1.0 ms response time (10%–90%).
Designed for differential pressure sensing (P1 > P2), it features built-in temperature compensation over 0°C to +85°C, with TcSpan ≤ ±2.0 %VFSS and TcOffset ≤ ±1.0 mV across –40°C to +125°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa differential (14.5 psi); defines measurable pressure delta between P1 and P2 ports. |
| Full Scale Output | 40 mV typical at 10 V supply; enables direct ADC interfacing without amplification in many 12-bit+ systems. |
| Supply Voltage | 10 VDC nominal (6–16 V range); ratiometric operation ensures output scaling tracks supply variations. |
| Linearity Error | ±0.4 %VFSS (end-point method); supports <0.5% total error budget in calibrated systems. |
| Response Time | 1.0 ms (10%–90%); suitable for dynamic pressure monitoring in motor control and robotics. |
| Operating Temp | –40°C to +125°C; allows deployment in under-hood automotive or industrial enclosures without external heating/cooling. |
| Offset Voltage | ±1.0 mV at min pressure; reduces zero-adjustment burden in analog signal chains. |
Pinout & Package
MPX2102D is packaged in MPAK (Case 1320), a surface-mount ceramic package with stainless steel cap and dual pressure ports. Dimensions: 29.08 × 17.40 × 7.75 mm (L×W×H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | GND | Ground reference for supply and output; must be low-impedance return path to minimize noise coupling. |
| Pin 2 | –VOUT | Negative output terminal; forms differential pair with Pin 4 for common-mode rejection of supply noise. |
| Pin 3 | VS | Positive supply input (6–16 VDC); powers internal Wheatstone bridge and compensation circuitry. |
| Pin 4 | +VOUT | Positive output terminal; voltage increases linearly with applied differential pressure (P1 > P2). |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Reduces need for external thermistor networks or software correction in 0–85°C environments. |
| Laser-trimmed span and offset | Eliminates manual potentiometer adjustment during production, lowering assembly cost and improving batch consistency. |
| Dual-port differential configuration | Enables bidirectional pressure sensing (P1 > P2 or P2 > P1) without hardware reconfiguration. |
| Ratiometric output | Output scales with supply voltage, simplifying designs using shared ADC reference derived from same supply rail. |
| Silicone gel isolation | Protects die and wire bonds from moisture and particulates while transmitting pressure signal reliably over life. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXM2102D | Same core die and specs; MPAK package (Case 1320) with rail packaging instead of tray; identical pinout and electrical behavior. | No functional difference; selected when tape-and-reel or rail delivery required for SMT line integration. | Drop-in replacement for MPX2102D in automated assembly; verify reel orientation and ESD handling per MPAK spec. |
| MPXV2102GP | Gauge configuration (not differential); single port referenced to ambient; 0–100 kPa range but no P2 vacuum port; 344B package. | Requires open-air reference; unsuitable for sealed differential measurements; used where ambient pressure is stable and accessible. | Only viable if system design permits ambient-referenced measurement and mechanical mounting matches Case 344B footprint. |
Compared with MPX2102D, MPXM2102D offers identical performance in a logistics-optimized MPAK variant, while MPXV2102GP trades differential capability for gauge simplicity-requiring redesign of porting and reference strategy.

FAQ
What is the pressure type supported by the MPX2102D?
The MPX2102D is a differential pressure sensor, meaning it measures the pressure difference between two ports: P1 (positive pressure side) and P2 (vacuum/reference side). Its specified range is 0–100 kPa differential, and it outputs a voltage proportional to that delta. This differs from absolute or gauge variants in the MPX2102 family, which use different internal references.
What is the supply voltage range for reliable operation of the MPX2102D?
The MPX2102D operates reliably with a supply voltage from 6 VDC to 16 VDC, with 10 VDC as the nominal excitation. It is ratiometric: output voltage scales linearly with supply voltage, so using the same supply for both the MPX2102D and the ADC reference improves measurement accuracy. Operating outside this range may induce self-heating errors.
How is temperature compensated in the MPX2102D?
The MPX2102D integrates on-chip temperature compensation circuitry that corrects for span and offset drift across 0°C to +85°C. This is achieved via thin-film resistors and laser trimming during manufacturing-not external components. The datasheet specifies TcSpan ≤ ±2.0 %VFSS and TcOffset ≤ ±1.0 mV over –40°C to +125°C, confirming compensation effectiveness beyond the compensated range.
What package type does the MPX2102D use, and how are its ports configured?
The MPX2102D uses the Unibody Package (Case 344C), a through-hole ceramic package with stainless steel cap and two distinct pressure ports: P1 (marked side, positive pressure) and P2 (unmarked side, vacuum/reference). Port identification is confirmed by the "Pressure (P1) Side Delineation" table in the datasheet, where MPX2102D is explicitly assigned to Case 344C with P1 identified as the side with part marking.
Can the MPX2102D be used in sealed or hazardous environments?
The MPX2102D incorporates silicone gel isolation over the die and wire bonds, providing protection against moisture, dust, and mild chemical exposure. However, Freescale specifies that qualification testing used dry air as the pressure medium; other media-including liquids, corrosive gases, or high-humidity environments-may degrade long-term reliability. For sealed or hazardous use, consult NXP's media compatibility guidance before deployment.
