ASDXL10G24R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDXL10G24R-DO is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 0.36PSI (2.49kPa) operating pressure range and 12-bit I2C digital output. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is not required.

The sensor features temperature compensation, operates across -20°C to 105°C, and is housed in an 8-DIP module package with PC pin termination. Its vented gauge configuration and barbless male tube port (0.09" / 2.29mm) are critical design parameters for system integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDXL10G24R-DO is determined by the following critical parameters that must align with system requirements:

Pressure Range Compatibility: The ASDXL10G24R-DO operates at 0.36PSI with a maximum pressure of 3PSI. Substitute parts must accommodate the target pressure measurement range of the application.

Output Interface: The ASDXL10G24R-DO provides 12-bit I2C digital output. Substitute parts may feature different output types (analog voltage, PWM, or alternative digital protocols) depending on system signal conditioning capabilities.

Electrical Supply: Both the main part and substitutes operate within 4.75V ~ 5.25V supply voltage range, ensuring direct compatibility with standard 5V logic systems.

Mechanical Interface: The vented gauge configuration, barbless male tube port (0.09" diameter), and 8-DIP module package define the physical integration requirements.

Environmental Specifications: Operating temperature range (-20°C ~ 105°C), accuracy (±2%), and temperature compensation are standard across the ASDX/ASDXL series.

Compliance & Status: RoHS compliance, MSL rating, and product availability status are secondary selection criteria when primary functional parameters are satisfied.

Engineering Selection Recommendations

ASDXRRX001PGAA5 as Primary Substitute:

The ASDXRRX001PGAA5 is the designated substitute for the obsolete ASDXL10G24R-DO based on the following engineering criteria:

Product Availability: The ASDXRRX001PGAA5 is classified as Active with 2580 units in stock, ensuring supply chain continuity compared to the obsolete ASDXL10G24R-DO.

Mechanical Compatibility: Both sensors share identical 8-DIP module packaging, through-hole mounting, PC pin termination, and barbless male tube port configuration. Physical board integration requires no modification.

Electrical Supply: Identical 4.75V ~ 5.25V supply voltage range ensures direct power compatibility without additional voltage regulation.

Environmental Performance: Both sensors operate across -20°C ~ 105°C with ±2% accuracy and temperature compensation, meeting equivalent environmental specifications.

Compliance Alignment: Both parts are RoHS compliant with MSL rating 1 (Unlimited), maintaining regulatory and reliability standards.

Critical Differences Requiring System Evaluation:

The ASDXRRX001PGAA5 operates at 1PSI (6.89kPa) with a 2PSI maximum pressure, compared to the ASDXL10G24R-DO at 0.36PSI with 3PSI maximum. Applications requiring the original 0.36PSI range must evaluate whether the higher 1PSI operating point is acceptable for system accuracy and measurement resolution.

The ASDXRRX001PGAA5 provides analog voltage output (0.5V ~ 4.5V) instead of I2C digital output. System signal conditioning and microcontroller interface must be redesigned to accommodate analog-to-digital conversion.

The ASDXRRX001PGAA5 features a dual port configuration compared to the single port on the ASDXL10G24R-DO, providing additional system flexibility for redundant or multi-point pressure measurement.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDXL10G24R-DO without circuit modification?

A: Physical board integration is compatible due to identical 8-DIP module packaging and PC pin termination. However, the output interface differs fundamentally: the ASDXL10G24R-DO provides I2C digital output while the ASDXRRX001PGAA5 provides analog voltage output (0.5V ~ 4.5V). Microcontroller firmware and signal conditioning circuits must be redesigned to process analog signals instead of I2C protocol.

Q: What is the pressure range difference between these sensors?

A: The ASDXL10G24R-DO operates at 0.36PSI (2.49kPa) with a 3PSI maximum pressure rating. The ASDXRRX001PGAA5 operates at 1PSI (6.89kPa) with a 2PSI maximum pressure rating. Applications requiring measurement of pressures below 1PSI may experience reduced resolution or accuracy with the substitute part.

Q: Are the tube port connections compatible?

A: Both sensors feature barbless male tube ports. The ASDXL10G24R-DO has a single 0.09" (2.29mm) port, while the ASDXRRX001PGAA5 has a dual 0.09" (2.31mm) port configuration. The port diameter difference (0.02mm) is negligible for standard tubing applications. The dual port on the substitute provides additional connection flexibility.

Q: Do both sensors require the same supply voltage?

A: Yes. Both the ASDXL10G24R-DO and ASDXRRX001PGAA5 operate within the 4.75V ~ 5.25V supply voltage range. No additional power supply modifications are required for electrical compatibility.

Q: What are the accuracy specifications for both sensors?

A: Both sensors provide ±2% accuracy with temperature compensation across the -20°C ~ 105°C operating range. Accuracy performance is equivalent between the two parts.

Q: Is the ASDXRRX001PGAA5 suitable for applications requiring I2C communication?

A: No. The ASDXRRX001PGAA5 provides analog voltage output only. Applications requiring I2C protocol must either retain the original ASDXL10G24R-DO if available from inventory, or implement an external analog-to-digital converter with I2C interface to bridge the communication protocol difference.

Q: What is the inventory status of both sensors?

A: The ASDXL10G24R-DO (obsolete) has 1102 units in stock. The ASDXRRX001PGAA5 (active) has 2580 units in stock, providing greater long-term supply availability.

Q: Are both sensors RoHS compliant?

A: Yes. Both the ASDXL10G24R-DO and ASDXRRX001PGAA5 are RoHS compliant with MSL rating 1 (Unlimited), meeting environmental and reliability standards.
