Product details
Overview
MPXH6250AC6T1 from Freescale is an absolute pressure sensor with 20–250 kPa range, ratiometric analog output (4.896 V typical at full scale), ±1.5% accuracy over 0–85 °C, and on-chip temperature compensation from –40 to +125 °C; used in fuel-injected engine manifolds for MAP sensing.
For engineers reviewing the MPXH6250AC6T1 datasheet, MPXH6250AC6T1 pinout, MPXH6250AC6T1 application, or MPXH6250AC6T1 equivalent, this page delivers verified electrical specs, validated SSOP-8 pin mapping, automotive-grade thermal performance data, and direct alternatives for LPG/CNG system design.
Technical Context
The MPXH6250AC6T1 integrates a piezoresistive silicon diaphragm with bipolar op-amp signal conditioning and thin-film resistor networks for high-level analog output. Its sealed vacuum reference enables absolute pressure measurement with fluorosilicone gel isolation of die and wire bonds.
It operates ratiometrically with 4.74–5.46 V supply, delivers 20.4 mV/kPa sensitivity, exhibits 1.0 ms response time, and maintains ±0.25% VFSS offset stability after 1000-hour pulsed pressure/temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–250 kPa absolute; supports intake manifold pressure monitoring across idle to wide-open throttle in gasoline/LPG engines. |
| Output Voltage | 0.204 V (min) to 4.896 V (typ) at 5.1 V supply; directly interfaces with 5 V ADCs without level-shifting. |
| Accuracy | ±1.5% of full-scale span over 0–85 °C; eliminates need for external calibration in production ECU designs. |
| Supply Voltage | 4.74–5.46 V DC; ratiometric operation ensures output scaling tracks supply variations, reducing power rail noise sensitivity. |
| Response Time | 1.0 ms (10–90%); captures rapid transients during throttle snap tests and transient fuel control events. |
| Operating Temp | –40 to +125 °C ambient; qualified for under-hood automotive placement with no derating required. |
| Offset Stability | ±0.25% VFSS after 1000 hr stress; ensures long-term MAP accuracy in fielded vehicles without recalibration. |
Pinout & Package
MPXH6250AC6T1 uses Case 98ARH99089A: 8-pin super small outline package (SSOP), surface-mount, thermoplastic PPS body with chamfered corner marking Pin 1. Porting enables tube attachment for remote LPG sensing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Do not connect; internal device connection only - floating or grounded causes measurement error. |
| 2 | VS | Positive supply input (4.74–5.46 V); requires 1 μF decoupling capacitor per datasheet Figure 4. |
| 3 | GND | Analog ground reference; must be star-connected to ADC ground to avoid common-mode noise. |
| 4 | VOUT | Ratiometric analog output (0.204–4.896 V); drives 51 kΩ load per recommended circuit; connects directly to MCU ADC. |
| 5–8 | DNC | All unconnected; internal die connections - soldering or routing to these pins invalidates calibration. |
Key Features
| Feature | Design Value |
|---|---|
| On-chip temperature compensation | Compensates offset and span drift across –40 to +125 °C, enabling single-point calibration in production. |
| Fluorosilicone gel isolation | Protects die and wire bonds from moisture and hydrocarbon vapors while transmitting pressure accurately for LPG/CNG use. |
| Sealed vacuum reference | Enables true absolute pressure measurement critical for barometric correction in altitude-compensated fuel maps. |
| Ratiometric output | Output scales linearly with supply voltage, eliminating gain error from 5 V rail tolerance in automotive power systems. |
| SSOP-8 surface mount | Compact 3.81 mm × 4.93 mm footprint supports high-density ECU PCB layouts and automated reflow assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXH6250A6T1 | Same die, identical electrical specs, but packaged in Case 98ARH99066A (non-gel variant); lacks fluorosilicone isolation. | Suitable for dry-air or inert gas environments only; not rated for LPG/CNG exposure. | Select MPXH6250A6T1 only when media compatibility is guaranteed and gel isolation is unnecessary. |
| MPXHZ6250AC6T1 | Same package (98ARH99089A) and gel construction, but includes enhanced media resistance for aggressive fluids and higher humidity. | Validated for extended exposure to water vapor, methanol blends, and condensing environments where standard MPXH6250AC6T1 may degrade. | Choose MPXHZ6250AC6T1 for humid, mixed-fuel, or condensing applications requiring longer-term stability. |
Compared with MPXH6250A6T1, MPXH6250AC6T1 adds fluorosilicone gel for LPG compatibility; compared with MPXHZ6250AC6T1, it offers lower cost for standard autogas use without requiring enhanced chemical resistance.

FAQ
What is the pressure range and reference type of the MPXH6250AC6T1?
The MPXH6250AC6T1 is an absolute pressure sensor with a specified range of 20 to 250 kPa referenced to a sealed vacuum cavity. It outputs a ratiometric analog voltage proportional to applied absolute pressure, making it suitable for manifold absolute pressure (MAP) sensing where barometric compensation is required. The MPXH6250AC6T1 achieves this using a monolithic silicon diaphragm with on-chip vacuum reference.
Does the MPXH6250AC6T1 require external calibration or signal conditioning?
No, the MPXH6250AC6T1 does not require external calibration or signal conditioning. It integrates on-chip bipolar op-amp circuitry, thin-film resistor networks, and factory-trimmed temperature compensation, delivering a fully conditioned 0.204–4.896 V analog output at 5.1 V supply. The MPXH6250AC6T1 is designed for direct connection to a 5 V ADC input with only recommended decoupling (1 μF) on VS.
What is the meaning of "C6T1" in MPXH6250AC6T1?
The "C6T1" suffix in MPXH6250AC6T1 denotes two key attributes: "C" indicates the media-resistant fluorosilicone gel version (vs. non-gel "A" variants), and "6T1" specifies tape-and-reel packaging in Case 98ARH99089A. This distinguishes MPXH6250AC6T1 from rail-packaged versions (e.g., MPXH6250AC6U) and non-gel variants like MPXH6250A6T1.
Can the MPXH6250AC6T1 be used with LPG or CNG fuel systems?
Yes, the MPXH6250AC6T1 is explicitly qualified for LPG and CNG applications due to its fluorosilicone gel isolation, which protects the die and wire bonds from hydrocarbon vapors while transmitting pressure accurately. The MPXH6250AC6T1 datasheet cites "autogas vehicles powered by green gases (for example, LPG and CNG)" as a typical application, and its porting options support remote tube mounting.
What are the supply current and thermal specifications of the MPXH6250AC6T1?
The MPXH6250AC6T1 draws 6.0 mA typical supply current at 5.1 V, with a maximum of 10 mA. It operates across –40 to +125 °C ambient temperature and is temperature-compensated from –40 to +125 °C. Its offset stability is ±0.25% VFSS after 1000 hours of pulsed pressure and temperature cycling - a specification confirmed in Freescale's MPXH6250A Rev. 4.0 datasheet.
