Product details
Overview
MPX5100GSX from NXP Semiconductors is a monolithic silicon piezoresistive pressure sensor in unibody package, configured for gauge pressure measurement (0–100 kPa), delivering ratiometric analog output (0.2 V to 4.7 V at 5 V supply), ±2.5% full-scale accuracy over 0–85 °C, and 1 ms response time. It serves as a primary pressure transduction element in microcontroller-based medical and industrial control systems.
For engineers reviewing the MPX5100GSX datasheet, MPX5100GSX pinout, MPX5100GSX application, or MPX5100GSX equivalent, this page delivers verified technical context, validated pin functions, real-world use cases, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The MPX5100GSX integrates a patented silicon shear-stress strain gauge with on-chip thin-film temperature compensation and dual-stage gain amplification. Its transfer function is VOUT = VS × (0.009 × P + 0.04), making output strictly ratiometric to supply voltage and linear with applied pressure.
It operates across –40 to +125 °C, supports 4.75–5.25 VDC excitation, draws ≤10 mA supply current, and features fluorosilicone gel die protection for environmental robustness. The device is media-rated for dry air only; non-dry-air media require factory consultation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 0–100 kPa gauge - defines full-scale operating span for calibrated analog output. |
| Output Voltage Range | 0.20–4.70 VDC at VS = 5.0 V - provides 4.5 V full-scale span compatible with 5 V ADC reference rails. |
| Accuracy | ±2.5 %VFSS over 0–85 °C - includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 1.0 ms (10%–90%) - enables real-time pressure monitoring in dynamic pump/motor control loops. |
| Supply Voltage | 4.75–5.25 VDC - ensures stable ratiometric operation within standard 5 V system rails. |
| Sensitivity | 45 mV/kPa - yields ~4.5 V output at 100 kPa, enabling direct interface to 12-bit+ ADCs without gain staging. |
| Operating Temperature | –40 to +125 °C - supports deployment in automotive engine bays and industrial enclosures without external thermal management. |
Pinout & Package
MPX5100GSX uses the 6-lead unibody package (case 98ASB42796B), featuring an epoxy-encapsulated silicon die with stainless steel metal cover and integrated port for gauge pressure sensing. The package is surface-mountable with self-aligning footprint per NXP-recommended land pattern.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Analog output voltage proportional to applied pressure; requires 1 µF decoupling capacitor to ground per Figure 7. |
| 2 | GND | Analog ground reference for internal amplifier stages; must be connected to low-noise system ground plane. |
| 3 | VS | Positive supply input (4.75–5.25 VDC); requires 0.01 µF ceramic + 470 pF film capacitor filtering per Figure 7. |
| 4–6 | DNC | Internally connected; must remain unconnected - no external tie to GND, VS, or signal traces. |
Key Features
| Feature | Design Value |
|---|---|
| Piezoresistive silicon shear-stress gauge | Enables high repeatability and low hysteresis (<±0.5 %VFSS offset stability after 1000-hour stress test). |
| On-chip temperature compensation | Eliminates need for external thermistor or digital calibration in 0–85 °C medical and appliance applications. |
| Ratiometric output architecture | Preserves measurement integrity when sharing 5 V rail with microcontroller ADC reference, reducing supply noise sensitivity. |
| Dual-port-capable unibody construction | Supports gauge-mode operation with one side exposed to ambient (P2) and one side to process pressure (P1). |
| Epoxy unibody encapsulation | Provides mechanical durability and moisture resistance in white goods and patient monitoring housings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar gauge pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXV5100GC6U | Same 0–100 kPa gauge range and 45 mV/kPa sensitivity, but in 8-lead small-outline package (98ASB17757C) with different pinout and port orientation. | Designed for space-constrained PCB layouts requiring side-port mounting; lacks unibody mechanical ruggedness of MPX5100GSX. | Select when board area is limited and side-port mechanical integration is required; verify land pattern compatibility. |
| MPX5010DP | Lower 0–10 kPa range, same unibody package, ±2.5% accuracy, but optimized for differential pressure with dual ports. | Intended for low-pressure differential sensing (e.g., filter clogging, airflow), not gauge-mode ambient-referenced measurement. | Select only for differential applications; not a functional substitute for MPX5100GSX's gauge configuration. |
Compared with MPX5100GSX, MPXV5100GC6U offers identical electrical performance in a smaller, side-port SOIC package-ideal for compact designs-but sacrifices unibody mechanical robustness. MPX5010DP provides comparable accuracy and packaging but targets differential, not gauge, pressure ranges, limiting its applicability in ambient-referenced systems.

FAQ
What is the pressure type and range supported by the MPX5100GSX?
The MPX5100GSX is a gauge pressure sensor with a specified range of 0 to 100 kPa. It measures pressure relative to ambient atmospheric pressure using a single port exposed to the process medium, while the opposite side is vented to atmosphere. This configuration is confirmed in NXP's MPX5100 datasheet Rev. 14, Table 4 and ordering information section for MPX5100GP variants.
Does the MPX5100GSX require external calibration or temperature compensation?
No, the MPX5100GSX includes fully integrated on-chip temperature compensation and factory calibration. Its output remains within ±2.5% VFSS accuracy over 0–85 °C without external circuitry, as verified in Section 3 and Table 4 of the official datasheet. The device implements thin-film metallization and bipolar processing to achieve this self-contained performance.
What is the correct pinout and connection guidance for MPX5100GSX?
The MPX5100GSX uses a 6-pin unibody package (98ASB42796B) with pins 1–3 assigned to VOUT, GND, and VS respectively; pins 4–6 are DNC and must remain unconnected. Power supply decoupling requires a 0.01 µF ceramic capacitor between VS and GND, plus a 470 pF film capacitor, per Figure 7 in the MPX5100 datasheet.
Can MPX5100GSX be used with media other than dry air?
No - the MPX5100GSX is qualified and rated exclusively for dry air as the pressure medium. Use with other gases or liquids may degrade long-term reliability or cause irreversible damage due to fluorosilicone gel incompatibility. NXP explicitly states this limitation in Section 3 of the MPX5100 datasheet and advises contacting factory support for media-specific validation.
What is the warm-up time and output stability specification for MPX5100GSX?
The MPX5100GSX has a specified warm-up time of 20 ms - defined as the time required to meet output voltage specifications after pressure stabilization. Its offset stability is ±0.5 %VFSS after 1000 hours of pulsed pressure and temperature cycling, confirming suitability for long-duration deployments in white goods and industrial controllers.
