MPX4400AP Equivalent & Substitute Parts

Part Overview

The MPX4400AP is an absolute pressure sensor manufactured by NXP USA Inc., designed for board mount applications with a measurement range of 2.9PSI to 58.02PSI (20kPa to 400kPa). The device outputs analog voltage and operates across -40°C to 125°C. This part is currently obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MPX4400AP is based on strict alignment of the following critical parameters:

• Pressure Type: Absolute pressure measurement capability
• Operating Pressure Range: 2.9PSI ~ 58.02PSI (20kPa ~ 400kPa) minimum coverage
• Output Type: Analog voltage output
• Accuracy: ±1.5%
• Supply Voltage Compatibility: Overlapping operational voltage range
• Operating Temperature Range: -40°C ~ 125°C
• Compliance: ROHS3 and REACH compliance maintained

The MPXH6400AC6T1 meets all these criteria as an active, manufacturer-recommended substitute from the same NXP product family.

Parameter Comparison

Engineering Selection Recommendations

The MPXH6400AC6T1 is the manufacturer-recommended substitute for the obsolete MPX4400AP. Both components maintain identical pressure measurement ranges, accuracy specifications, and operating temperature limits. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection. The MPXH6400AC6T1 features a higher maximum pressure rating (232.06PSI versus 58.02PSI), providing additional safety margin in applications without introducing incompatibility.

The primary design difference is the package type: the substitute transitions from a through-hole configuration to surface mount (8-SOIC), requiring PCB layout modification. The substitute includes temperature compensation and barbless port connection, representing functional enhancements over the original design.

Frequently Asked Questions (FAQ)

Q: Can MPXH6400AC6T1 directly replace MPX4400AP without circuit modification?

A: The electrical specifications are compatible within the defined operating ranges. However, the package transition from through-hole to surface mount (8-SOIC) requires PCB redesign. The supply voltage range overlap (4.64V ~ 5.36V) ensures operational compatibility.

Q: What is the significance of the higher maximum pressure rating on the substitute?

A: The MPXH6400AC6T1 maximum pressure rating of 232.06PSI (1600kPa) exceeds the operating range of 58.02PSI (400kPa). This provides overpressure protection without affecting measurement accuracy within the specified operating window.

Q: Are there differences in output voltage characteristics?

A: The MPXH6400AC6T1 specifies output voltage as 0.2V ~ 4.8V. The original MPX4400AP does not provide explicit output voltage specification. Both maintain ±1.5% accuracy across their respective operating pressure ranges.

Q: Does the port connection style affect substitution feasibility?

A: The MPXH6400AC6T1 features a male barbless tube port (0.13" / 3.3mm), whereas the MPX4400AP port configuration is not specified. Port compatibility must be evaluated against the specific application's fluid connection requirements.

Q: Are compliance certifications maintained in the substitute?

A: Yes. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels (MSL 1 - Unlimited), satisfying equivalent regulatory requirements.
