Product details
Overview
MPXH6400A6T1 from NXP is an absolute pressure sensor with 20–400 kPa range, ratiometric analog output (0.2–4.8 V at 5 V supply), ±1.5% full-scale accuracy over 0 °C to 85 °C, and on-chip temperature compensation from −40 °C to +125 °C. It serves as a signal-conditioned transducer in fuel-injected engine manifolds and LPG/CNG vehicle systems.
For engineers reviewing the MPXH6400A6T1 datasheet, MPXH6400A6T1 pinout, MPXH6400A6T1 application, or MPXH6400A6T1 equivalent, this page delivers verified package mapping (Case 98ARH99066A), calibrated output behavior, media-resistant gel isolation, and validated alternatives for automotive and industrial pressure sensing.
Technical Context
The MPXH6400A6T1 integrates a piezoresistive silicon diaphragm with thin-film resistor networks and bipolar op-amp circuitry to deliver a high-level analog voltage output directly proportional to absolute pressure. Its monolithic construction includes on-die temperature compensation and factory calibration across pressure and temperature.
It operates ratiometrically with 4.64–5.36 V supply, draws 6–10 mA, exhibits 1.0 ms response time, and maintains ±0.25% full-scale offset stability after 1000 pressure cycles. The fluorosilicone gel isolates the die while transmitting pressure to the vacuum-referenced silicon diaphragm.

Pinout & Package
MPXH6400A6T1 uses Case 98ARH99066A - a super small outline surface-mount package with fluorosilicone gel isolation and stainless steel cap for media resistance. Pin 1 is identified by chamfered corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | DNC | Internal connection; must remain unconnected per datasheet to avoid performance degradation. |
| 2 | VS | 5 V supply input; ratiometric operation requires stable excitation within 4.64–5.36 V. |
| 3 | GND | Analog ground reference; must be star-connected to minimize noise coupling into VOUT. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXHZ6400A6T1 | Same pressure range (20–400 kPa), identical accuracy and package (98ARH99066A), but features enhanced media resistance for harsher chemical exposure. | Preferred for direct contact with aggressive refrigerants or solvents where fluorosilicone gel longevity is critical. | Select MPXHZ6400A6T1 when media compatibility beyond LPG/CNG is required; otherwise MPXH6400A6T1 is optimal for cost-sensitive automotive deployments. |
| MPX5700AP | Wider pressure range (0–700 kPa), larger SOIC-8 package (98ARH99089A), ±2.0% accuracy, no gel isolation. | Suitable for general-purpose industrial gauges but lacks media resistance for fuel systems. | Choose MPX5700AP only for non-fuel, non-moisture-critical applications where higher pressure range outweighs size and isolation needs. |
Compared with MPXHZ6400A6T1, the MPXH6400A6T1 offers identical performance in LPG/CNG environments at lower unit cost; versus MPX5700AP, it delivers superior media resistance and smaller footprint but trades off maximum pressure capability.

FAQ
What is the pressure range and output behavior of the MPXH6400A6T1?
The MPXH6400A6T1 measures absolute pressure from 20 kPa to 400 kPa. Its output voltage ranges from 0.133 V to 4.866 V at 5 V supply, following the ratiometric transfer function VOUT = VS × (0.002421 × P – 0.00842). This linear relationship enables direct interface with microcontroller ADCs without external signal conditioning. The MPXH6400A6T1 maintains this behavior across its full operating temperature range of −40 °C to +125 °C.
Is the MPXH6400A6T1 suitable for LPG or CNG fuel systems?
Yes, the MPXH6400A6T1 is explicitly qualified for LPG and CNG vehicle applications. Its Case 98ARH99066A package incorporates fluorosilicone gel isolation that resists swelling and degradation when exposed to liquefied petroleum gas and compressed natural gas. The datasheet confirms porting and mounting options for tube attachment in remote sensing configurations, making the MPXH6400A6T1 a validated choice for bi-fuel engine control modules.
What are the supply requirements and current draw for the MPXH6400A6T1?
The MPXH6400A6T1 operates from a 4.64–5.36 V DC supply and draws 6.0–10.0 mA typical current. Its ratiometric design ensures output scaling remains proportional to supply voltage, improving noise immunity in electrically noisy automotive environments. Decoupling with a 1 μF capacitor near VS and GND is recommended per Figure 4 in the datasheet to stabilize operation. The MPXH6400A6T1 does not require external regulators or precision references.
How is temperature compensation implemented in the MPXH6400A6T1?
The MPXH6400A6T1 features on-chip temperature compensation using thin-film resistor networks and bipolar op-amp circuitry. Compensation is factory-calibrated across −40 °C to +125 °C, maintaining ±1.5% full-scale accuracy over 0–85 °C. The internal circuitry applies a temperature-dependent multiplier (1.0 at 0–85 °C, 3.0 at −40 °C, 1.75 at +125 °C) to correct offset and span drift. No external components or software correction are needed-the MPXH6400A6T1 delivers compensated output directly from VOUT.
What is the meaning of "DNC" pins on the MPXH6400A6T1?
"DNC" stands for "Do Not Connect." Pins 1 and 5–8 on the MPXH6400A6T1 are internal device connections with no external functionality. Per Table 1 and Figure 2 of the datasheet, these pins must remain unconnected to any trace, pad, or ground plane. Connecting them risks performance degradation or permanent damage. Only pins 2 (VS), 3 (GND), and 4 (VOUT) are functional-this three-terminal configuration simplifies layout and reduces routing complexity in space-constrained ECUs. The MPXH6400A6T1 relies entirely on these three terminals for operation.
