ASDXL10D44R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDXL10D44R-DO is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement with I2C digital output. This 12-bit sensor operates across a 0.36PSI (2.49kPa) differential pressure range with ±2% accuracy and temperature compensation. The product is currently classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDXL10D44R-DO requires evaluation based on the following critical parameters that define functional compatibility:

Mechanical Compatibility: Port size and style (Male - 0.09" tube, dual barbless configuration) must match to ensure proper pneumatic connection without adapter requirements.

Electrical Interface: The original part uses I2C digital output with 12-bit resolution. Substitute parts must maintain compatible communication protocol and resolution to function within existing system architecture.

Pressure Measurement Characteristics: Operating pressure range, pressure type (differential vs. gauge), and accuracy specification determine whether a substitute can perform the intended measurement function.

Environmental and Supply Parameters: Operating temperature range (-20°C ~ 105°C) and supply voltage (4.75V ~ 5.25V) must be met or exceeded by substitute parts.

Package and Mounting: 8-DIP Module through-hole mounting must be preserved for PCB compatibility.

Regulatory Compliance: RoHS compliance and REACH status must be maintained.

The ASDXRRX001PGAA5 is identified as a substitute part within the Honeywell ASDX series family. However, this substitute exhibits differences in pressure type (vented gauge vs. differential), output interface (analog voltage vs. I2C), and output resolution (0.5V ~ 4.5V vs. 12-bit digital), which represent functional deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASDXL10D44R-DO is classified as obsolete. The ASDXRRX001PGAA5 maintains active product status with Honeywell, ensuring ongoing availability and manufacturing support.

Compliance and Certification: Both parts maintain RoHS compliance and equivalent regulatory standing (ECCN: EAR99, HTSUS: 9026.20.4000), supporting continued use in regulated applications.

Functional Differences: The substitute part operates as a vented gauge pressure sensor with analog voltage output, whereas the original part functions as a differential pressure sensor with I2C digital output. These differences require system-level evaluation to determine applicability. The substitute part's higher operating pressure range (1PSI vs. 0.36PSI) and different pressure type indicate it addresses different measurement scenarios.

Mechanical Compatibility: Port size specifications show minor dimensional variation (2.29mm vs. 2.31mm), both within the 0.09" male tube dual barbless configuration. This variation is within typical manufacturing tolerance for pneumatic connections.

Supply and Environmental Parameters: Both parts share identical supply voltage (4.75V ~ 5.25V) and operating temperature range (-20°C ~ 105°C), ensuring compatibility with existing power and thermal management systems.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDXL10D44R-DO in existing applications?

A: Direct replacement requires system-level compatibility assessment. The substitute part differs in pressure type (vented gauge vs. differential), output interface (analog voltage vs. I2C), and pressure range (1PSI vs. 0.36PSI). These differences necessitate evaluation of the application's measurement requirements and signal processing architecture.

Q: What is the primary functional difference between these two sensors?

A: The ASDXL10D44R-DO measures differential pressure (pressure difference between two ports) with digital I2C output. The ASDXRRX001PGAA5 measures vented gauge pressure (pressure relative to atmosphere) with analog voltage output. These represent different measurement methodologies suited to different application requirements.

Q: Are the pneumatic port connections compatible?

A: Both parts feature male 0.09" tube dual barbless ports. The port size specification shows a minor dimensional difference (2.29mm vs. 2.31mm), which falls within standard manufacturing tolerance for pneumatic tubing connections. Mechanical compatibility is supported.

Q: What is the significance of the product status difference?

A: The ASDXL10D44R-DO is obsolete, indicating Honeywell has discontinued manufacturing and support. The ASDXRRX001PGAA5 maintains active status, ensuring continued availability, manufacturing consistency, and technical support from the manufacturer.

Q: Can I use an analog-to-digital converter to adapt the ASDXRRX001PGAA5 output to replace the I2C interface?

A: Output interface conversion is a system design consideration outside the scope of direct component substitution. Such adaptation would require additional circuitry and system validation.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both parts operate across -20°C ~ 105°C with temperature compensation, ensuring equivalent thermal performance characteristics.

Q: What is the inventory status for these parts?

A: The ASDXL10D44R-DO has 1031 pieces in stock as new original inventory. The ASDXRRX001PGAA5 has 2580 pieces in stock as new original inventory, providing greater availability for procurement.
