ASDX001D44D Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX001D44D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with analog voltage output. This component operates within a 1PSI (6.89kPa) differential pressure range and delivers output signals between 0.5V and 4.5V. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ASDX001D44D is determined by the following critical parameters: output voltage range (0.5V ~ 4.5V), supply voltage specification (4.75V ~ 5.25V), package type (8-DIP Module), mounting configuration (Through Hole), accuracy (±2%), operating temperature range (-20°C ~ 105°C), port style (Barbless), and termination style (PC Pin).

Two substitute parts are identified based on compatibility with these parameters:

ASDXRRX001PDAA5 (Direct Substitute - Differential Type): Maintains differential pressure measurement with ±1PSI (±6.89kPa) operating pressure, identical output voltage range, supply voltage, accuracy, temperature range, package configuration, and termination style. Product status is Active. Port size specification is 0.09" (2.31mm) Tube, Dual, representing a minor dimensional variation within acceptable tolerance for tube connections.

ASDXRRX001PGAA5 (Similar Substitute - Gauge Type): Operates as a vented gauge pressure sensor with 1PSI (6.89kPa) operating pressure. Shares identical output voltage range, supply voltage, accuracy, temperature range, package configuration, and termination style. Pressure type differs from differential to vented gauge, requiring application-level compatibility verification. Product status is Active. Port size specification is 0.09" (2.31mm) Tube, Dual.

Parameter Comparison

Engineering Selection Recommendations

ASDXRRX001PDAA5 is the primary recommended substitute for ASDX001D44D applications. This part maintains differential pressure measurement functionality, identical electrical specifications, and active product status. Both components comply with RoHS requirements and REACH regulations. The minor port size dimensional difference (2.29mm versus 2.31mm) falls within standard manufacturing tolerances for barbed tube connections and does not affect functional compatibility.

ASDXRRX001PGAA5 serves as an alternative only for applications where vented gauge pressure measurement is functionally equivalent to differential pressure measurement. This substitution requires application-level validation to confirm that gauge pressure operation satisfies system requirements. The part maintains identical electrical output characteristics, supply voltage specifications, accuracy, and temperature range. Active product status and full compliance certifications apply.

Both substitute parts are available in active production status, ensuring long-term supply chain continuity compared to the obsolete ASDX001D44D.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX001PDAA5 directly replace ASDX001D44D without circuit modifications?

A: Yes. ASDXRRX001PDAA5 maintains identical output voltage range (0.5V ~ 4.5V), supply voltage requirements (4.75V ~ 5.25V), accuracy (±2%), and 8-DIP Module package configuration. The differential pressure measurement type is preserved. No circuit modifications are required.

Q: What is the difference between the port sizes 0.09" (2.29mm) and 0.09" (2.31mm)?

A: Both specifications reference 0.09 inch nominal diameter with minor dimensional variations. For barbless tube connections, this 0.02mm difference is within standard manufacturing tolerance and does not affect functional compatibility or connection integrity.

Q: When should ASDXRRX001PGAA5 be used instead of ASDXRRX001PDAA5?

A: ASDXRRX001PGAA5 operates as a vented gauge pressure sensor, measuring pressure relative to atmospheric reference. Use this part only when the application requires gauge pressure measurement rather than differential pressure measurement between two independent pressure sources.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ASDXRRX001PDAA5 and ASDXRRX001PGAA5 are RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance status of ASDX001D44D.

Q: What is the inventory status for substitute parts?

A: ASDXRRX001PDAA5 has 882 pieces in stock. ASDXRRX001PGAA5 has 2580 pieces in stock. Both parts maintain active product status with ongoing manufacturing support.

Q: Do the substitute parts include amplified output features?

A: ASDXRRX001PDAA5 and ASDXRRX001PGAA5 include temperature compensation. The original ASDX001D44D specified amplified output; substitute parts feature temperature compensation as the primary signal conditioning method.
