Product details
Overview
MPX5100A from NXP Semiconductors is an obsolete but historically documented monolithic silicon piezoresistive pressure sensor in unibody package, configured for absolute pressure measurement with 0–100 kPa range, ±2.5% full-scale accuracy over 0–85 °C, and ratiometric 4.75–5.25 V supply operation - used in patient monitoring, pump control, and white goods where analog pressure feedback to microcontroller A/D inputs is required.
For engineers reviewing the MPX5100A datasheet, MPX5100A pinout, MPX5100A application, or MPX5100A equivalent, this page delivers verified technical context, confirmed pin functions (VOUT/GND/VS + three DNC pins), calibrated transfer function (VOUT = VS × (0.009×P − 0.095)), mechanical package data (Case 98ASB42796B), and two validated alternative parts for legacy design continuity.
Technical Context
The MPX5100A integrates a patented silicon shear-stress strain gauge with on-chip thin-film temperature compensation and dual-stage gain circuitry, delivering a high-level analog output directly proportional to applied absolute pressure. Its architecture includes ground-reference shift circuitry and internal decoupling support for stable microcontroller interfacing.
It operates ratiometrically with supply voltage (VS), meaning output scale and offset track VS variations - enabling direct connection to ADC references without external scaling. The device requires no external calibration and exhibits 1 ms response time with 20 ms warm-up time after power-on.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0 to 100 kPa absolute - defines usable sensing span for vacuum-to-atmospheric applications. |
| Accuracy | ±2.5% of full-scale span (VFSS) over 0–85 °C - quantifies total error budget including linearity, hysteresis, and thermal drift. |
| Supply Voltage | 4.75–5.25 VDC - ratiometric operation ensures output scales linearly with supply, simplifying reference design. |
| Output Span | 4.500 V typical full-scale span (VFSS) at 5 V supply - yields ~45 mV/kPa sensitivity for predictable A/D resolution planning. |
| Response Time | 1.0 ms (10% to 90%) - supports dynamic pressure monitoring in motor/pump control loops. |
| Operating Temp | −40 to +125 °C - enables deployment in industrial and automotive under-hood environments. |
| Offset Stability | ±0.5% VFSS after 1000-hour pulsed pressure/temperature cycling - confirms long-term reliability in fielded systems. |
Pinout & Package
MPX5100A uses the 6-lead unibody package (Case 98ASB42796B), epoxy-encapsulated with stainless steel metal cover and fluorosilicone gel protection for media isolation. Port side is identified by presence of pressure port; marking side is not used for this variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to absolute pressure - connects directly to microcontroller A/D input with optional RC filtering. |
| 2 | GND | Analog ground reference - must be star-connected to minimize noise coupling into sensitive output path. |
| 3 | VS | Positive supply input - requires local 1.0 μF + 0.01 μF decoupling per datasheet Figure 7 to suppress switching noise. |
| 4 | DNC | Internal lead frame connection - must remain floating; soldering or grounding causes calibration shift or damage. |
| 5 | DNC | Internal die bond pad - electrically isolated from active circuitry; no external connection permitted. |
| 6 | DNC | Internal thermal compensation node - tied to internal reference; external connection invalidates temperature compensation. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Eliminates need for external thermistor networks or software correction tables across 0–85 °C operating range. |
| Patented silicon shear-stress strain gauge | Delivers superior hysteresis and repeatability vs. conventional piezoresistive elements, critical for medical-grade monitoring. |
| Ratiometric output | Enables shared VREF between MPX5100A and MCU ADC, removing supply-voltage drift as an error source. |
| Durable epoxy unibody construction | Withstands mechanical shock and vibration in pump/motor assemblies without performance degradation. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture and condensation in white goods and HVAC applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5100AP | Direct functional successor: identical 0–100 kPa absolute range, same 98ASB42796B package, updated calibration and RoHS compliance. | Drop-in replacement for new designs; supports same PCB footprint and firmware interface. | Select MPX5100AP for production builds requiring active NXP support and current qualification status. |
| MPXV5100GP | Gauge configuration (0–100 kPa relative to ambient), 8-lead SOIC package, different pinout (VS/GND/VOUT on pins 2/3/4), ±2.5% VFSS accuracy. | Requires layout change and firmware offset adjustment; suitable where ambient-referenced measurement suffices. | Choose MPXV5100GP only when redesigning for surface-mount assembly and ambient pressure referencing is acceptable. |
Compared with MPX5100A, MPX5100AP offers identical electrical behavior and mechanical fit with updated manufacturing controls, while MPXV5100GP trades absolute reference for SOIC packaging and gauge functionality - necessitating hardware and software adaptation.

FAQ
What is the pressure type and range supported by the MPX5100A?
The MPX5100A is an absolute pressure sensor with a specified range of 0 to 100 kPa. It measures pressure relative to perfect vacuum, making it suitable for applications such as barometric sensing and sealed-system monitoring. Its transfer function is defined as VOUT = VS × (0.009 × P − 0.095), where P is absolute pressure in kPa - a key parameter confirmed in the MPX5100 Rev. 14 datasheet for the MPX5100AP variant, which shares identical core specifications with the MPX5100A.
Is the MPX5100A still in active production?
No, the MPX5100A has been formally obsoleted by NXP Semiconductors as of Rev. 14 (December 2018) of the MPX5100 datasheet, which explicitly states "Deleted obsolete part numbers MPX5100A and MPX5100D." However, Aetrix Electronics maintains limited legacy inventory and traceable sourcing channels for MPX5100A to support repair and maintenance of installed base systems.
What is the correct pinout and connection guidance for MPX5100A?
The MPX5100A uses a 6-pin unibody package with pins 1 (VOUT), 2 (GND), and 3 (VS) as active terminals; pins 4–6 are marked DNC (Do Not Connect) and must remain unconnected - they serve internal lead frame or thermal compensation functions. This pinout is documented in Figure 2 and Table 1 of the MPX5100 Rev. 14 datasheet. Connecting any DNC pin risks calibration loss or permanent damage to the MPX5100A.
How does temperature affect MPX5100A output accuracy?
The MPX5100A features on-chip temperature compensation that limits total error to ±2.5% of full-scale span (VFSS) over 0–85 °C. Its nominal transfer function includes a temperature multiplier factor, and offset stability is rated at ±0.5% VFSS after 1000-hour stress testing. These values are measured and guaranteed per the MPX5100 Rev. 14 datasheet - confirming that MPX5100A maintains clinical- and industrial-grade repeatability without external correction.
Can MPX5100A be replaced with MPX5100DP or MPX5100GP in the same circuit?
No - MPX5100DP is a differential pressure sensor and MPX5100GP is a gauge (vented) sensor, each with distinct transfer functions and zero-pressure output points. The MPX5100A's absolute configuration (VOUT = VS × (0.009 × P − 0.095)) differs fundamentally from MPX5100GP's (VOUT = VS × (0.009 × P + 0.04)). Substituting them without firmware and calibration changes will cause systematic measurement errors in the MPX5100A-based system.
