ASDX005D44R Equivalent & Substitute Parts

Part Overview

The ASDX005D44R is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component operates at 5PSI (34.47kPa) differential pressure with analog voltage output ranging from 0.5V to 4.5V. The sensor features amplified output and temperature compensation, housed in an 8-DIP module with through-hole PC pin termination and dual male barbless tube ports (0.09" / 2.29mm).

The ASDX005D44R is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and redesign requirements for legacy systems utilizing this pressure sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX005D44R is determined by compatibility across the following critical parameters:

Mandatory Compatibility Parameters:

• Manufacturer: Honeywell Sensing and Productivity Solutions (ASDX series)
• Package / Case: 8-DIP Module
• Termination Style: PC Pin
• Mounting Type: Through Hole
• Output Type: Analog Voltage
• Output Range: 0.5V ~ 4.5V
• Supply Voltage: 4.75V ~ 5.25V
• Accuracy: ±2%
• Operating Temperature: -20°C ~ 105°C
• Port Style: Barbless
• RoHS Compliance: RoHS Compliant

Variable Parameters (Application-Dependent):

• Pressure Type: Differential vs. Vented Gauge
• Operating Pressure: 5PSI vs. alternative pressure ratings
• Port Size: Tube diameter specifications
• Maximum Pressure: Overpressure rating

Substitute parts must maintain identical electrical output characteristics, package form factor, and termination style. Pressure type and operating pressure ratings may differ based on application requirements.

Engineering Selection Recommendations

ASDXRRX005PGAA5 (Direct Substitute)

The ASDXRRX005PGAA5 is the primary substitute for the obsolete ASDX005D44R. Both components share identical operating pressure (5PSI), output voltage range (0.5V ~ 4.5V), supply voltage (4.75V ~ 5.25V), accuracy (±2%), and thermal operating range (-20°C ~ 105°C). The ASDXRRX005PGAA5 maintains the same 8-DIP module package, PC pin termination, and through-hole mounting configuration.

The primary difference is pressure type: the ASDX005D44R measures differential pressure, while the ASDXRRX005PGAA5 measures vented gauge pressure. This distinction is critical and must be evaluated against application requirements. The ASDXRRX005PGAA5 has a lower maximum pressure rating (10PSI vs. 20PSI), which may limit use in high-overpressure environments.

The ASDXRRX005PGAA5 is currently in active production status with 1131 units in stock, ensuring availability for new designs and legacy system support.

ASDXRRX001PGAA5 (Similar Substitute)

The ASDXRRX001PGAA5 is a lower-pressure variant suitable only for applications requiring 1PSI (6.89kPa) operating pressure. This component shares identical electrical output characteristics, package form factor, and termination style with the ASDX005D44R. The ASDXRRX001PGAA5 is appropriate for low-pressure measurement applications and is currently in active production with 2580 units in stock.

The ASDXRRX001PGAA5 is not suitable as a direct replacement for the ASDX005D44R in applications requiring 5PSI measurement capability.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX005PGAA5 directly replace the ASDX005D44R in all applications?

A: The ASDXRRX005PGAA5 provides electrical and mechanical compatibility with the ASDX005D44R. However, the pressure type differs: ASDX005D44R measures differential pressure, while ASDXRRX005PGAA5 measures vented gauge pressure. Applications must be evaluated to determine if this pressure type change is acceptable. Both components deliver identical 0.5V ~ 4.5V output across 5PSI operating pressure.

Q: What is the difference between differential and vented gauge pressure measurement?

A: Differential pressure sensors measure the pressure difference between two independent pressure sources applied to separate ports. Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. The selection between these types depends on the specific application measurement requirement.

Q: Are the port sizes identical between the ASDX005D44R and substitute parts?

A: The ASDX005D44R features 0.09" (2.29mm) tube ports, while both substitute parts feature 0.09" (2.31mm) tube ports. This minor dimensional difference (0.02mm) may require evaluation for tubing compatibility in existing installations.

Q: Do all three components share the same package and termination?

A: Yes. The ASDX005D44R, ASDXRRX005PGAA5, and ASDXRRX001PGAA5 all use 8-DIP module packaging with PC pin through-hole termination, enabling direct board-level substitution from a mechanical and electrical interface perspective.

Q: What is the significance of the amplified output feature on the ASDX005D44R?

A: The ASDX005D44R includes amplified output, while the substitute parts feature temperature compensation only. This functional difference may affect signal conditioning requirements in the application circuit. Existing designs must be evaluated to determine if amplified output is essential or if temperature-compensated output is sufficient.

Q: Are all three components RoHS compliant?

A: Yes. The ASDX005D44R, ASDXRRX005PGAA5, and ASDXRRX001PGAA5 are all RoHS compliant with moisture sensitivity level 1 (unlimited), meeting environmental and regulatory requirements for commercial and industrial applications.

Q: Which substitute part should be selected for a new design?

A: For applications requiring 5PSI vented gauge pressure measurement, the ASDXRRX005PGAA5 is the appropriate selection. For applications requiring 1PSI vented gauge pressure measurement, the ASDXRRX001PGAA5 is suitable. Both are active production components with established supply availability.
