ASDX015D44D Pressure Sensor - Equivalent & Substitute Parts

Part Overview

The ASDX015D44D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 15PSI (103.42kPa) differential pressure range and 0.5V to 4.5V analog voltage output. This component features amplified output and temperature compensation in an 8-DIP module package with male barbless tube ports (0.09" / 2.29mm dual).

The ASDX015D44D is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDX015D44D are identified based on strict alignment with the following critical parameters:

Direct Substitutes must maintain:

• Differential pressure type classification
• 15PSI (103.42kPa) operating pressure specification
• 0.5V ~ 4.5V analog voltage output
• 4.75V ~ 5.25V supply voltage range
• ±2% accuracy
• 8-DIP module package
• Through hole mounting
• Male barbless tube port configuration
• -20°C ~ 105°C operating temperature range
• RoHS compliance

Similar Parts share the same series, package, output characteristics, and electrical specifications but differ in pressure type or operating pressure range. These parts are suitable only when application requirements permit deviation from the original pressure specification.

Parameter Comparison

Engineering Selection Recommendations

ASDXRRX015PDAA5 is the direct substitute for ASDX015D44D. Both components share identical pressure specifications (15PSI differential), output characteristics (0.5V ~ 4.5V), supply voltage requirements (4.75V ~ 5.25V), accuracy (±2%), package type (8-DIP module), and operating temperature range (-20°C ~ 105°C). The ASDXRRX015PDAA5 is currently in active production status with 735 units in stock, providing supply continuity for the obsolete ASDX015D44D. Both parts are RoHS compliant and carry identical ECCN and HTSUS classifications. The minor port size tolerance difference (2.31mm versus 2.29mm) falls within standard mechanical compatibility for male barbless tube connections.

ASDXRRX001PGAA5 is a similar part within the ASDX series but is not a direct substitute. This component differs fundamentally in pressure type (vented gauge versus differential) and operating pressure range (1PSI versus 15PSI). Selection of ASDXRRX001PGAA5 is appropriate only when application requirements have changed to accommodate lower pressure measurement ranges and vented gauge pressure sensing. This part is currently in active production with 2580 units in stock.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX015PDAA5 be used as a direct replacement for ASDX015D44D?

A: Yes. Both components maintain identical differential pressure specifications (15PSI), output voltage range (0.5V ~ 4.5V), supply voltage (4.75V ~ 5.25V), accuracy (±2%), package configuration (8-DIP module), and operating temperature range (-20°C ~ 105°C). The ASDXRRX015PDAA5 is the active production equivalent of the obsolete ASDX015D44D.

Q: What is the difference between ASDXRRX015PDAA5 and ASDXRRX001PGAA5?

A: ASDXRRX015PDAA5 is a differential pressure sensor rated for 15PSI operation. ASDXRRX001PGAA5 is a vented gauge pressure sensor rated for 1PSI operation. These components serve different pressure measurement applications and are not interchangeable without application redesign.

Q: Are there mechanical compatibility concerns with the port size difference between ASDX015D44D (2.29mm) and ASDXRRX015PDAA5 (2.31mm)?

A: Both components feature male barbless tube ports with nominal 0.09" (approximately 2.3mm) diameter specifications. The 0.02mm tolerance difference is within standard mechanical compatibility for tube connection interfaces and does not present compatibility issues for standard pneumatic tubing applications.

Q: What is the significance of the "amplified output" feature listed for ASDX015D44D but not ASDXRRX015PDAA5?

A: The ASDX015D44D specification lists amplified output as a feature. The ASDXRRX015PDAA5 specification lists temperature compensation. Both components deliver 0.5V ~ 4.5V analog voltage output with ±2% accuracy across the -20°C ~ 105°C operating range. The output voltage characteristics are functionally equivalent for circuit design purposes.

Q: Are both substitute parts RoHS compliant?

A: Yes. ASDXRRX015PDAA5 and ASDXRRX001PGAA5 are both RoHS compliant, matching the RoHS compliance status of the ASDX015D44D.

Q: What is the current availability status of these components?

A: ASDXRRX015PDAA5 (direct substitute) is in active production with 735 units in stock. ASDXRRX001PGAA5 (similar part) is in active production with 2580 units in stock. The original ASDX015D44D is obsolete but 800 units remain in inventory.
