Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDX030A24R are identified based on strict parameter matching within the ASDX series from Honeywell. The substitution logic is organized into two categories:

Direct Equivalent (Functional Replacement): Parts that maintain identical or equivalent electrical and mechanical specifications, allowing direct substitution without circuit or mechanical redesign.

Similar Alternative (Application-Dependent): Parts that share the same package, output type, and supply voltage but differ in pressure range or pressure type. These require application review to confirm suitability.

Key Parameters Determining Substitution:

• Pressure type (Absolute vs. Vented Gauge)
• Operating pressure rating
• Output voltage range
• Supply voltage range
• Package type and termination style
• Port size and style
• Operating temperature range

Engineering Selection Recommendations

ASDXACX030PAAA5 (Direct Equivalent - Recommended Primary Substitute)

The ASDXACX030PAAA5 is the primary substitute for the obsolete ASDX030A24R. Both components share identical pressure specifications (30PSI absolute), output characteristics (0.5V to 4.5V), supply voltage requirements (4.75V to 5.25V), accuracy (±2%), and operating temperature range (-20°C to 105°C). The ASDXACX030PAAA5 is classified as Active product status, ensuring ongoing availability and support. Both components are RoHS Compliant and feature temperature compensation. The port size tolerance differs marginally (2.29mm vs. 2.31mm), which remains within standard tubing compatibility. The ASDXACX030PAAA5 is packaged as an 8-DIP Module, maintaining through-hole mounting compatibility. This part is suitable for direct substitution in applications requiring 30PSI absolute pressure measurement.

ASDXRRX001PGAA5 (Similar Alternative - Application-Dependent)

The ASDXRRX001PGAA5 shares the same package type, output voltage range, supply voltage, accuracy, and operating temperature as the ASDX030A24R. However, this part operates as a Vented Gauge pressure sensor with a 1PSI operating pressure rating, compared to the 30PSI absolute pressure of the main part. The maximum pressure rating is 2PSI. This component is suitable only for applications where the system design can accommodate a vented gauge pressure measurement at 1PSI instead of 30PSI absolute pressure. The ASDXRRX001PGAA5 features a dual port configuration. This part is classified as Active and has the highest inventory availability (2580 Pcs). Selection of this alternative requires confirmation that the application pressure range and pressure type (vented gauge vs. absolute) are compatible with the original design requirements.

Both substitute parts are RoHS Compliant and manufactured by Honeywell Sensing and Productivity Solutions within the ASDX series, ensuring consistency with the original component family.

Frequently Asked Questions (FAQ)

Q1: Can the ASDXACX030PAAA5 be used as a direct replacement for the ASDX030A24R?

A: Yes. The ASDXACX030PAAA5 is a direct functional equivalent. Both components measure 30PSI absolute pressure, output 0.5V to 4.5V, operate on 4.75V to 5.25V supply, maintain ±2% accuracy, and support the same operating temperature range (-20°C to 105°C). Both are 8-DIP through-hole packages with barbless male tube ports. The ASDXACX030PAAA5 is Active product status, providing supply continuity for the obsolete ASDX030A24R.

Q2: What is the difference between the ASDX030A24R and ASDXACX030PAAA5?

A: The primary differences are product status and packaging designation. The ASDX030A24R is Obsolete, while the ASDXACX030PAAA5 is Active. The ASDX030A24R specifies "8-DIP (0.600", 15.24mm), Top Port," while the ASDXACX030PAAA5 is designated as "8-DIP Module." The ASDX030A24R includes "Amplified Output" in its feature set, whereas the ASDXACX030PAAA5 lists only "Temperature Compensated." Port size tolerance differs slightly (2.29mm vs. 2.31mm), which is within standard tubing compatibility margins. Electrical and pressure specifications are identical.

Q3: Why is the ASDXRRX001PGAA5 listed as a substitute if it has different pressure specifications?

A: The ASDXRRX001PGAA5 is listed as a similar alternative, not a direct equivalent. It shares the same package type (8-DIP Module), output voltage range (0.5V to 4.5V), supply voltage (4.75V to 5.25V), accuracy (±2%), and operating temperature range (-20°C to 105°C). However, it measures 1PSI vented gauge pressure instead of 30PSI absolute pressure. This part is suitable only for applications where the design can accommodate a different pressure type and range. Selection requires verification that the application requirements align with 1PSI vented gauge measurement.

Q4: What does "Vented Gauge" pressure type mean compared to "Absolute" pressure?

A: Absolute pressure sensors measure pressure relative to a perfect vacuum. Vented gauge pressure sensors measure pressure relative to atmospheric pressure. The ASDX030A24R measures absolute pressure (30PSI), while the ASDXRRX001PGAA5 measures vented gauge pressure (1PSI). These are fundamentally different measurement types. Selection between them depends on the application's pressure measurement requirements.

Q5: Are there any mechanical compatibility concerns with the port sizes?

A: The ASDX030A24R specifies a male 0.09" (2.29mm) tube port, while both substitute parts specify 0.09" (2.31mm) tube ports. This 0.02mm tolerance difference is within standard tubing compatibility ranges and should not present mechanical issues. Both substitute parts maintain the barbless port style of the original component.

Q6: What is the significance of the "Amplified Output" feature listed for the ASDX030A24R but not the ASDXACX030PAAA5?

A: The ASDX030A24R explicitly lists "Amplified Output" as a feature, while the ASDXACX030PAAA5 lists only "Temperature Compensated." Both components output 0.5V to 4.5V analog voltage with identical supply and accuracy specifications. The absence of "Amplified Output" in the ASDXACX030PAAA5 specification does not indicate reduced functionality; it reflects differences in how the manufacturers document their product features. Both components are suitable for applications requiring 0.5V to 4.5V analog output.

Q7: Which substitute part should be selected for new designs?

A: For new designs requiring 30PSI absolute pressure measurement with 0.5V to 4.5V output, the ASDXACX030PAAA5 is the appropriate selection. It is Active product status, ensuring long-term availability and support. It maintains all electrical and pressure specifications of the obsolete ASDX030A24R while providing design continuity within the ASDX series.

Q8: Are both substitute parts RoHS Compliant?

A: Yes. Both the ASDXACX030PAAA5 and ASDXRRX001PGAA5 are RoHS Compliant, matching the compliance status of the ASDX030A24R. Both components are also classified as REACH Unaffected and carry ECCN EAR99 designation.
