Product details
Overview
MPXA4100A6T1 from Freescale Semiconductor is a monolithic, signal-conditioned, temperature-compensated and calibrated absolute pressure sensor designed for manifold absolute pressure (MAP) sensing in automotive engine control systems. It delivers a ratiometric analog output (0.3–4.9 V) over a 20–105 kPa range, with ±1.8% full-scale span accuracy from 0°C to 85°C, and operates on a 4.85–5.35 V supply. Its primary role is measuring intake manifold air pressure to compute fuel injection timing and volume.
For engineers reviewing the MPXA4100A6T1 datasheet, MPXA4100A6T1 pinout, MPXA4100A6T1 application, or MPXA4100A6T1 equivalent, this page provides verified technical context, package mapping, real-world use cases, and validated alternative options for engine management, industrial vacuum monitoring, and microcontroller-based pressure acquisition systems.
Technical Context
The MPXA4100A6T1 integrates a piezoresistive silicon sensing element with on-chip bipolar signal conditioning, thin-film temperature compensation, and factory calibration. Its transfer function is VOUT = VS × (0.01059 × P − 0.1518), where P is absolute pressure in kPa and VS is supply voltage (5.1 V ± 0.25 V).
It uses a thermoplastic (PPS) small-outline surface-mount package (Case 482-01) with fluorosilicone gel isolation, rated for −40°C to +125°C operation and 400 kPa maximum pressure. The device requires external decoupling (1.0 μF + 0.01 μF + 470 pF) per Figure 3 to meet electrical specifications and ensure A/D interface stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 20–105 kPa (2.9–15.2 psi); covers full operational vacuum-to-boost range of naturally aspirated and moderately boosted gasoline engines. |
| Output Voltage Range | 0.3–4.9 V at VS = 5.1 V; ratiometric to supply, enabling direct ADC interfacing without external reference scaling. |
| Accuracy | ±1.8% VFSS over 0°C to 85°C; includes linearity, temperature hysteresis, pressure hysteresis, TcSpan, and TcOffset contributions. |
| Response Time | 1.0 ms (10% to 90%); supports real-time closed-loop fuel control at engine speeds up to ~10,000 RPM. |
| Supply Voltage | 4.85–5.35 V DC; compatible with standard automotive 5 V regulator rails and tolerant of battery voltage fluctuations. |
| Operating Temperature | −40°C to +125°C ambient; qualified for under-hood placement without external thermal shielding. |

Pinout & Package
MPXA4100A6T1 is housed in a 6-pin small-outline surface-mount package (Case 482-01), thermoplastic (PPS) body with fluorosilicone gel media isolation. Pin 1 is identified by a notch or dot marking on the package top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2 | GND | Analog ground reference; must be connected to low-noise system ground plane, separate from digital return paths. |
| 3 | VS | Positive supply input (4.85–5.35 V); requires local 1.0 μF ceramic + 0.01 μF film decoupling per datasheet Figure 3. |
| 4 | No Connect | Internally unconnected; must remain floating-no PCB trace or solder mask opening required. |
| 5 | No Connect | Internally unconnected; must remain floating-no routing or termination permitted. |
| 6 | No Connect | Internally unconnected; no electrical or mechanical function; omitted from footprint land pattern. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPXAZ4100A6U | Uses media-resistant fluorosilicone gel; identical pressure range, output, and package but rated for aggressive chemical exposure. | Required where sensor contacts fuel vapor, brake fluid, or industrial solvents; not needed for dry-air manifold sensing. | Select MPXAZ4100A6U only if media compatibility beyond dry air is confirmed in your system environment. |
| MPX4100AS | Unibody package (Case 867E-03) with stove-pipe port; same core die but different mechanical interface and 3-pin TO-style footprint. | Used in legacy harness-mounted or through-hole designs; incompatible with SMT reflow and board space-constrained layouts. | Choose MPX4100AS only when mechanical mounting constraints mandate ported through-hole assembly-not for new SMT designs. |
Compared with MPXAZ4100A6U and MPX4100AS, the MPXA4100A6T1 offers optimal balance of SMT manufacturability, cost, and performance for modern automotive and industrial MAP applications-requiring no gel upgrade or mechanical redesign unless media or mounting dictates otherwise.

FAQ
What is the operating pressure range of the MPXA4100A6T1?
The MPXA4100A6T1 operates over an absolute pressure range of 20 kPa to 105 kPa (2.9 to 15.2 psi), covering full vacuum to mild boost conditions typical in gasoline engine intake manifolds. This range is factory calibrated and specified with ±1.8% full-scale span accuracy from 0°C to 85°C. Operation outside this range may cause output saturation or nonlinearity, and the device is rated for a maximum pressure of 400 kPa without damage.
Does the MPXA4100A6T1 require external signal conditioning?
No, the MPXA4100A6T1 does not require external signal conditioning. It integrates a fully signal-conditioned analog output stage-including amplification, temperature compensation, and factory calibration-delivering a ratiometric 0.3–4.9 V output directly compatible with standard 5 V microcontroller ADC inputs. Only external power supply decoupling (1.0 μF + 0.01 μF + 470 pF) is required per the datasheet to maintain specified accuracy and noise performance.
What package type and pin configuration does the MPXA4100A6T1 use?
The MPXA4100A6T1 uses a 6-pin small-outline surface-mount package (Case 482-01) with thermoplastic (PPS) body and fluorosilicone gel isolation. Pin 1 is VOUT, Pin 2 is GND, Pin 3 is VS, and Pins 4–6 are no-connect terminals. The package is designed for reflow soldering and features a standardized footprint per Figure 5 in the datasheet, with pin 1 identified by a notch or dot marking on the top surface.
Is the MPXA4100A6T1 suitable for non-automotive applications?
Yes, the MPXA4100A6T1 is explicitly stated in its datasheet to be ideal for non-automotive applications including industrial vacuum monitoring, environmental data logging, and medical respiratory equipment. Its −40°C to +125°C operating temperature range, 1 ms response time, and ±0.5% VFSS offset stability after 1000-hour stress testing make it suitable for demanding embedded systems where reliability and long-term drift performance are critical.
How does the ratiometric output of the MPXA4100A6T1 benefit system design?
The ratiometric output of the MPXA4100A6T1 means its output voltage scales linearly with supply voltage (VS), so variations in VS from 4.85 V to 5.35 V do not introduce measurement error when the same supply powers both the MPXA4100A6T1 and the ADC reference. This eliminates the need for precision voltage references or post-processing gain correction, simplifies power architecture, and improves system-level accuracy in automotive environments where battery voltage fluctuates.
