ASDX100D44R Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX100D44R is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, rated for 100PSI (689.48kPa) with analog voltage output (0.5V ~ 4.5V). This component features amplified output and temperature compensation in an 8-DIP module package with through-hole mounting. The product is currently obsolete, making identification of equivalent and substitute parts essential for system maintenance, redesign, and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ASDX100D44R are identified based on the following criteria:

Compatible Parameters (Required for Substitution):

• Analog voltage output type (0.5V ~ 4.5V)
• Supply voltage range (4.75V ~ 5.25V)
• Accuracy specification (±2%)
• 8-DIP module package
• Through-hole mounting
• Temperature range (-20°C ~ 105°C)
• Port style (Barbless, Male tube connection)
• RoHS compliance

Pressure Type Consideration: The ASDX100D44R operates as a differential pressure sensor. Substitute parts may operate under different pressure measurement types (vented gauge vs. differential) provided all other electrical and mechanical parameters remain compatible. The pressure rating and type determine the specific application context but do not prevent functional substitution in systems where the measurement principle can be adapted.

Active vs. Obsolete Status: Direct substitutes with active product status are preferred for new procurement and long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

ASDXRRX100PGAA5 (Primary Substitute): This part is the direct equivalent for the ASDX100D44R in terms of pressure rating (100PSI operating pressure) and electrical specifications. The ASDXRRX100PGAA5 maintains identical output voltage range (0.5V ~ 4.5V), supply voltage (4.75V ~ 5.25V), accuracy (±2%), and package configuration (8-DIP module). The primary difference is the pressure measurement type (vented gauge vs. differential). This part carries active product status, ensuring availability and long-term supply chain support. The higher maximum pressure rating (200PSI vs. 150PSI) provides additional safety margin. Port dimensions are nominally equivalent (0.09" tube, 2.31mm vs. 2.29mm). This substitute is suitable for applications where vented gauge pressure measurement can replace differential pressure measurement.

ASDXRRX001PGAA5 (Limited Compatibility): This part shares identical electrical characteristics (output voltage, supply voltage, accuracy, package, mounting) and active product status. However, the operating pressure rating (1PSI) is substantially lower than the ASDX100D44R (100PSI). This part is suitable only for low-pressure applications and is not recommended as a general substitute for the main part. Selection of this part requires confirmation that system pressure requirements do not exceed 1PSI operating range.

Compliance and Certification: All substitute parts maintain RoHS compliance and operate within the same temperature range (-20°C ~ 105°C), ensuring regulatory and thermal compatibility with the original design.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX100PGAA5 directly replace ASDX100D44R in existing designs?

A: Electrical and mechanical compatibility is confirmed across output voltage, supply voltage, accuracy, package type, and mounting configuration. The primary design consideration is the pressure measurement type: ASDX100D44R measures differential pressure, while ASDXRRX100PGAA5 measures vented gauge pressure. Direct replacement is possible if the application can accommodate this measurement principle difference. Port dimensions are nominally equivalent (0.09" tube connection).

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

A: Differential pressure sensors measure the pressure difference between two independent ports. Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. System redesign may be required if the original application specifically requires differential measurement.

Q: Why is ASDXRRX001PGAA5 listed as a similar part rather than a direct substitute?

A: While ASDXRRX001PGAA5 shares identical electrical output characteristics and package configuration, its operating pressure rating (1PSI) is incompatible with applications requiring 100PSI measurement. This part is suitable only for low-pressure sensing applications.

Q: Are there any port connection compatibility issues between the main part and substitutes?

A: All parts feature male barbless tube connections at 0.09" diameter. Tube dimensions are nominally equivalent (2.29mm vs. 2.31mm), representing standard manufacturing tolerance variation. Mechanical compatibility is confirmed.

Q: What is the inventory status for substitute parts?

A: ASDXRRX100PGAA5 has 974 pieces in stock. ASDXRRX001PGAA5 has 2,580 pieces in stock. Both parts carry active product status, ensuring continued availability.

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

A: Yes. All parts operate across -20°C to 105°C, confirming thermal compatibility with the original design.

Q: Are there any RoHS or regulatory compliance differences?

A: All parts are RoHS compliant with identical ECCN (EAR99) and HTSUS classifications, confirming regulatory equivalence.
