ASDX015A24R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX015A24R-DO is a 15PSI absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component features I2C digital output, 12-bit resolution, and temperature compensation in an 8-DIP through-hole package with a 0.09" male tube port. The product is classified as obsolete, necessitating identification of equivalent alternatives for ongoing system support and new design implementations. Substitute parts must maintain functional compatibility across pressure measurement range, output protocol, electrical specifications, and physical mounting characteristics.

Substitute Part Grouping Explanation

Substitute parts for the ASDX015A24R-DO are classified into two categories based on functional compatibility:

Direct Equivalent (Functional Substitute): The ASDXACX015PA7A5 maintains identical core specifications: 15PSI absolute pressure measurement, I2C digital output, 12-bit resolution, ±2% accuracy, 4.75V ~ 5.25V supply voltage, temperature compensation, and through-hole mounting. The primary distinction is packaging format (8-DIP Module versus 8-DIP with Top Port) and tube port dimension tolerance (2.31mm versus 2.29mm). This part qualifies as a direct functional substitute where I2C protocol compatibility and pressure measurement range are critical requirements.

Partial Compatibility (Limited Substitute): The ASDXRRX001PGAA5 shares the ASDX series platform, barbless male tube port (0.09", 2.31mm), 8-DIP module package, temperature compensation, ±2% accuracy, and identical supply voltage range. However, this part operates at 1PSI vented gauge pressure with analog voltage output (0.5V ~ 4.5V), fundamentally different from the 15PSI absolute pressure with I2C output of the main part. This part is not suitable as a direct substitute but may serve in applications where pressure measurement requirements differ significantly.

Key Parameters Determining Substitution:

• Pressure measurement range (15PSI absolute)
• Output protocol (I2C digital)
• Output resolution (12-bit)
• Supply voltage compatibility (4.75V ~ 5.25V)
• Physical mounting (through-hole, 8-DIP package)
• Port interface (0.09" male tube, barbless)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (ASDXACX015PA7A5):

The ASDXACX015PA7A5 is the primary equivalent for the obsolete ASDX015A24R-DO. Both components maintain identical pressure measurement specifications (15PSI absolute), I2C digital output protocol, 12-bit resolution, and electrical operating parameters. The ASDXACX015PA7A5 is currently in active inventory (819 units available) and carries identical RoHS compliance and MSL ratings. The minor tube port dimension variance (2.31mm versus 2.29mm) and package format difference (8-DIP Module versus 8-DIP with Top Port) do not affect functional compatibility in applications where the original part was specified. This part is suitable for direct substitution in new designs and legacy system support.

For Alternative Applications (ASDXRRX001PGAA5):

The ASDXRRX001PGAA5 is not recommended as a substitute for the ASDX015A24R-DO in applications requiring 15PSI absolute pressure measurement with I2C output. This part operates at fundamentally different specifications: 1PSI vented gauge pressure with analog voltage output (0.5V ~ 4.5V). The ASDXRRX001PGAA5 is suitable only for applications with different pressure measurement requirements and analog signal processing capability. However, this part offers the advantage of active product status and higher inventory availability (2580 units), making it appropriate for new designs with compatible pressure and output specifications.

Compliance Considerations:

All three parts maintain RoHS compliance and MSL Level 1 ratings, ensuring compatibility with standard manufacturing and storage protocols. The ASDXACX015PA7A5 and ASDXRRX001PGAA5 are both manufactured by Honeywell Sensing and Productivity Solutions, maintaining supply chain consistency and technical support continuity.

Frequently Asked Questions (FAQ)

Q: Can the ASDXACX015PA7A5 directly replace the ASDX015A24R-DO in existing circuit boards?

A: The ASDXACX015PA7A5 is functionally equivalent and maintains identical I2C protocol, 12-bit output resolution, and 15PSI pressure measurement range. Both components use PC pin termination in 8-DIP through-hole packages. The tube port dimension tolerance difference (2.31mm versus 2.29mm) is within standard tubing compatibility ranges. Direct PCB substitution is supported without firmware or signal processing modifications.

Q: What is the primary difference between the ASDXACX015PA7A5 and ASDXRRX001PGAA5?

A: The ASDXACX015PA7A5 measures 15PSI absolute pressure with I2C digital output (12-bit), while the ASDXRRX001PGAA5 measures 1PSI vented gauge pressure with analog voltage output (0.5V ~ 4.5V). These represent different sensor configurations for different application requirements. The ASDXRRX001PGAA5 cannot substitute for the ASDX015A24R-DO in applications requiring 15PSI absolute measurement and I2C protocol.

Q: Are there any package compatibility issues when substituting the ASDXACX015PA7A5?

A: Both the ASDX015A24R-DO and ASDXACX015PA7A5 use 8-DIP through-hole packages with identical 0.600" (15.24mm) body width and PC pin termination. The primary package distinction is the port configuration (Top Port versus Module format). This difference does not affect PCB footprint compatibility or mounting procedures. Tube port connection remains identical (0.09" male barbless interface).

Q: Why is the ASDX015A24R-DO classified as obsolete?

A: The ASDX015A24R-DO is listed as obsolete by the manufacturer, indicating discontinued production. The ASDXACX015PA7A5 represents the current equivalent offering within the ASDX series. For new designs and legacy system support, the ASDXACX015PA7A5 is the recommended alternative, ensuring access to active inventory and ongoing manufacturer support.

Q: What supply voltage range applies to all three parts?

A: All three parts operate within the identical supply voltage range of 4.75V ~ 5.25V. This specification ensures compatibility with standard 5V digital logic systems and eliminates voltage regulation concerns during substitution.

Q: Are there accuracy differences between the substitute parts?

A: All three parts maintain ±2% accuracy specification. The ASDXACX015PA7A5 and ASDX015A24R-DO both provide this accuracy across the 15PSI measurement range. The ASDXRRX001PGAA5 maintains ±2% accuracy within its 1PSI measurement range. Accuracy specifications are independent of output protocol (I2C versus analog voltage).

Q: What is the operating temperature range for substitute parts?

A: All three parts operate across the identical temperature range of -20°C ~ 105°C with temperature compensation. This specification ensures consistent performance across industrial and commercial application environments without thermal derating.
