ASDXL10D44D Equivalent & Substitute Parts Reference

Part Overview

The ASDXL10D44D is a pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with compound pressure measurement capability. This component operates within a 0.36PSI (2.49kPa) range with analog voltage output and is housed in an 8-DIP module package. The product is currently classified as obsolete, making identification of equivalent substitute parts essential for system redesign, maintenance, and component sourcing in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDXL10D44D are identified based on the following critical parameters that determine functional compatibility:

Mechanical Compatibility: Port size, port style, mounting type, and package configuration must align with the original design to ensure physical integration without circuit board modifications.

Electrical Compatibility: Supply voltage range, output voltage range, and termination style must support existing signal conditioning and data acquisition circuits.

Performance Compatibility: Pressure measurement range, accuracy specification, and operating temperature range must satisfy application requirements.

Regulatory Compliance: RoHS compliance and REACH status must meet environmental and regulatory standards applicable to the end application.

The substitute parts listed below share the 8-DIP module package, through-hole mounting, PC pin termination, barbless dual tube ports, ±2% accuracy, -20°C ~ 105°C operating temperature, and 4.75V ~ 5.25V supply voltage with the ASDXL10D44D. However, variations exist in pressure type, operating pressure range, and output voltage range, which are documented in the parameter comparison table.

Parameter Comparison

Engineering Selection Recommendations

ASDXRRX010NDAA5 (Direct Manufacturer Substitute): This part shares identical pressure measurement range (0.36PSI / 2.49kPa) and maximum pressure specification (±0.72PSI / ±4.96kPa) with the ASDXL10D44D. The primary difference is pressure type classification: differential versus compound. Both parts maintain RoHS compliance, identical supply voltage specifications, and equivalent thermal operating range. The output voltage range differs (0.5 V ~ 4.5 V versus 2.5 V ~ 6.5 V), requiring signal conditioning circuit evaluation. Product status is obsolete, consistent with the main part.

ASDXRRX001PGAA5 (Similar Manufacturer Substitute): This part operates at a higher pressure range (1PSI / 6.89kPa) with maximum pressure of 2PSI (13.79kPa), representing a different pressure measurement class. Pressure type is vented gauge rather than compound. Output voltage range is 0.5 V ~ 4.5 V. Critically, this part maintains active product status, ensuring ongoing manufacturer support and availability. RoHS compliance and thermal operating range align with the original specification. Selection of this part requires confirmation that the higher pressure range and vented gauge configuration satisfy application requirements.

Compliance Considerations: All three parts maintain RoHS compliance and identical ECCN/HTSUS classifications, supporting regulatory continuity in system redesign.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX010NDAA5 directly replace ASDXL10D44D without circuit modifications?

A: Physical and electrical compatibility exists for package, mounting, termination, and supply voltage. However, the output voltage range differs (0.5 V ~ 4.5 V versus 2.5 V ~ 6.5 V), requiring evaluation of signal conditioning circuits and analog-to-digital converter input ranges. Pressure type differs (differential versus compound), which may affect application suitability depending on system requirements.

Q: What is the primary difference between compound and differential pressure measurement?

A: Compound pressure sensors measure pressure relative to atmospheric pressure in both positive and negative directions. Differential pressure sensors measure the pressure difference between two independent sources. Selection depends on application requirements for pressure reference.

Q: Why does ASDXRRX001PGAA5 have a higher operating pressure range?

A: ASDXRRX001PGAA5 is classified as a vented gauge sensor with 1PSI operating pressure and 2PSI maximum pressure, compared to the 0.36PSI operating range of the original part. This represents a different sensor class designed for higher pressure applications. Substitution is appropriate only when application requirements support this higher pressure range.

Q: Is ASDXRRX001PGAA5 preferable due to active product status?

A: Active product status indicates ongoing manufacturer support and availability. However, substitution suitability depends on pressure range, pressure type, and output voltage compatibility with the target application. Active status alone does not determine functional equivalence.

Q: Are port size differences between 2.29mm and 2.31mm significant?

A: Port sizes differ marginally (0.02mm). Mechanical compatibility with existing tubing and connectors must be verified during integration. Barbless port style is consistent across all parts.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. All parts operate within -20°C ~ 105°C, maintaining thermal compatibility with the original specification.

Q: What is the significance of ±2% accuracy across all parts?

A: Identical accuracy specification ensures measurement precision consistency. Accuracy does not differentiate between substitute options.
