Product details
Overview
MPX2102GP from Freescale Semiconductor is a gauge-pressure silicon piezoresistive sensor with on-chip temperature compensation, 0–100 kPa pressure range, 40 mV full-scale output (typical), and ±0.4%VFSS linearity over 0°C to +85°C. It delivers ratiometric voltage output directly proportional to applied differential pressure and is used in industrial pump control, medical diagnostics, and robotics sensing systems.
For engineers reviewing the MPX2102GP datasheet, MPX2102GP pinout, MPX2102GP application, or MPX2102GP equivalent, key selection criteria include its unibody Case 344B package, 4-pin configuration with ground/supply/±output terminals, gauge pressure type, and compatibility with 10 VDC excitation and dry-air media.
Technical Context
The MPX2102GP integrates a monolithic silicon diaphragm with laser-trimmed piezoresistive strain gauges and thin-film resistor networks for precision calibration. Its on-chip temperature compensation circuitry actively corrects span and offset drift across 0°C to +85°C, enabling stable operation without external signal conditioning.
It operates ratiometrically with 10 VDC supply (range 10–16 VDC), draws 6.0 mA typical supply current, and exhibits 1.0 ms response time (10%–90%). The device uses dry air as validated pressure media; non-standard media require factory consultation due to potential reliability impact.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa gauge pressure - defines usable input range for calibrated linear output |
| Full Scale Span | 40 mV typical at 10 VDC - sets analog output scaling for ADC interface design |
| Linearity Error | ±0.4%VFSS (end-point method) - determines maximum deviation from ideal transfer function |
| Supply Voltage | 10–16 VDC - enables ratiometric operation; 10 VDC is nominal for spec compliance |
| Response Time | 1.0 ms (10%–90%) - supports dynamic pressure monitoring up to ~350 Hz bandwidth |
| Operating Temp | −40°C to +125°C - specifies environmental envelope for sensor placement and thermal design |
| Temperature Comp | 0°C to +85°C - active compensation range where offset and span errors are minimized |
Pinout & Package
MPX2102GP uses the unibody Case 344B package: 4-pin, through-hole, stainless-steel-capped housing with port-attached P1 side identification. 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 |
|---|---|---|
| 1 | Ground | Reference node for supply and output; must be low-impedance connection to minimize noise |
| 2 | + Output | Positive differential output terminal; voltage increases with P1 > P2 pressure |
| 3 | + Supply | Excitation input; supplies 10–16 VDC; output scales ratiometrically with this voltage |
| 4 | − Output | Negative differential output terminal; completes Wheatstone bridge output path |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Reduces span and offset drift over 0°C to +85°C, eliminating need for external thermistor networks |
| Laser-trimmed calibration | Ensures factory-set accuracy for span and offset, minimizing post-mounting trimming effort |
| Gauge pressure configuration | Measures pressure relative to ambient atmosphere via single port (P1), simplifying mechanical integration |
| Ratiometric output | Output voltage scales linearly with supply voltage, improving system-level accuracy when using shared reference |
| Dry-air media qualification | Validated performance and long-term reliability only with dry air; alternate media require engineering review |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV2102GP | Small-outline package (Case 1369), same 0–100 kPa range and 40 mV output, but surface-mount compatible | Designed for space-constrained PCBs; lacks through-hole mounting and stainless-steel cap of MPX2102GP | Select MPXV2102GP for automated assembly and smaller footprint; retain MPX2102GP for ruggedized through-hole mounting |
| MPXM2102GS | MPAK package (Case 1320A), identical gauge configuration and specs, but rail-packaged and optimized for high-volume tape-and-reel handling | Targeted at high-throughput manufacturing; same electrical performance but different mechanical interface and port orientation | Choose MPXM2102GS for SMT production lines requiring reel-fed placement; MPX2102GP suits prototyping and low-volume through-hole builds |
Compared with MPX2102GP, MPXV2102GP offers SMT compatibility at the cost of reduced mechanical robustness, while MPXM2102GS delivers identical performance in a high-volume MPAK format-neither is pin-compatible, requiring layout changes, but all three share the same core transduction architecture and calibration.

FAQ
What pressure type does the MPX2102GP measure?
The MPX2102GP is a gauge pressure sensor, meaning it measures pressure relative to ambient atmospheric pressure. It has a single pressure port (P1) and uses the surrounding environment as its reference. This configuration is confirmed by its ordering designation "GP" (Gauge Pressure) and Case 344B package marking per Freescale's Pressure (P1)/Vacuum (P2) Side Identification Table. The MPX2102GP does not require a sealed vacuum reference and is intended for applications like pump discharge monitoring or liquid level sensing where ambient-referenced measurement is appropriate.
What is the recommended excitation voltage for MPX2102GP?
The MPX2102GP is specified for operation with a supply voltage of 10 VDC (typical), within a range of 10–16 VDC. At 10 VDC, it delivers a typical full-scale output of 40 mV with ±0.4%VFSS linearity. Operating above 10 VDC increases output amplitude but may induce self-heating error; Freescale explicitly warns that excitation beyond the specified range may degrade accuracy. The device is ratiometric, so output voltage scales linearly with supply voltage-making it compatible with systems sharing a common reference source.
Does MPX2102GP require external temperature compensation?
No, the MPX2102GP does not require external temperature compensation. It features integrated on-chip temperature compensation circuitry calibrated over 0°C to +85°C, which actively corrects both full-scale span and offset drift. This is confirmed in the "Features" section and Operating Characteristics table, where TcSpan and TcOffset are specified as ±2.0%VFSS and ±1.0 mV respectively. The compensation is factory-laser-trimmed and requires no external components, simplifying system design and reducing bill-of-materials cost compared to uncompensated sensors.
What is the maximum pressure rating for MPX2102GP?
The MPX2102GP has a maximum pressure rating of 400 kPa, as stated in the Maximum Ratings table. This is the absolute upper limit before risk of permanent damage or degradation. Its operational pressure range remains 0–100 kPa (gauge), and exceeding 100 kPa during normal use will cause output saturation but not immediate failure-however, sustained exposure above 100 kPa or transient spikes beyond 400 kPa may compromise long-term reliability. Freescale emphasizes that media other than dry air may further reduce safe operating margins.
Can MPX2102GP be used with fluids other than dry air?
Freescale explicitly states that the MPX2102GP's operating characteristics and reliability validation are based solely on dry air as the pressure media. Using liquids, corrosive gases, or humid air may adversely affect sensor performance and long-term reliability due to potential die contamination or gel degradation. The datasheet directs users to contact the factory for media compatibility evaluation in non-dry-air applications. Therefore, MPX2102GP should not be deployed with non-dry-air media without formal qualification-and even then, such use falls outside the manufacturer's guaranteed specifications.
