ASDX030D44R Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX030D44R is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring analog voltage output. This component operates at 30PSI (206.84kPa) differential pressure with dual output ranging from 0.5V to 4.5V. 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

Substitution of the ASDX030D44R is determined by the following critical parameters:

Pressure Rating Match: The operating pressure specification of 30PSI (206.84kPa) is the primary selection criterion. Substitute parts must maintain this pressure rating to ensure functional equivalence in the target application.

Output Characteristics: The analog voltage output range (0.5V ~ 4.5V) and supply voltage requirements (4.75V ~ 5.25V) must remain constant across substitute selections to maintain signal compatibility with downstream circuitry.

Pressure Type Consideration: The ASDX030D44R operates as a differential pressure sensor. Substitute parts may operate under different pressure types (vented gauge) provided all other electrical and mechanical parameters align with application requirements.

Package and Mounting Compatibility: The 8-DIP Module package with through-hole termination and dual male 0.09" tube ports establishes the mechanical interface requirements for direct substitution.

Accuracy and Temperature Range: The ±2% accuracy specification and -20°C to 105°C operating temperature range define the performance envelope for acceptable substitutes.

Parameter Comparison

Engineering Selection Recommendations

ASDXRRX030PGAA5 (Direct Substitute): This part is the primary equivalent for ASDX030D44R replacement. It maintains identical operating pressure (30PSI), output voltage range (0.5V ~ 4.5V), supply voltage (4.75V ~ 5.25V), accuracy (±2%), package type (8-DIP Module), and operating temperature range (-20°C ~ 105°C). The primary difference is pressure type classification (vented gauge versus differential). The ASDXRRX030PGAA5 is currently in active production status with 1110 units in stock, ensuring long-term availability and supply chain continuity. RoHS compliance and identical electrical specifications support direct substitution in applications where pressure type differentiation does not affect system performance.

ASDXRRX001PGAA5 (Similar Substitute - Limited Application): This part shares identical electrical output characteristics (0.5V ~ 4.5V), supply voltage (4.75V ~ 5.25V), accuracy (±2%), package type (8-DIP Module), and operating temperature range (-20°C ~ 105°C) with the ASDX030D44R. However, the operating pressure rating is 1PSI (6.89kPa) with a maximum pressure of 2PSI (13.79kPa), which differs significantly from the 30PSI specification of the main part. This substitute is applicable only in applications where the system pressure requirement is 1PSI or lower. The part is in active production with 2580 units in stock.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX030PGAA5 directly replace ASDX030D44R in all applications?

A: ASDXRRX030PGAA5 maintains all critical electrical and mechanical parameters required for functional equivalence: 30PSI operating pressure, 0.5V ~ 4.5V output, 4.75V ~ 5.25V supply voltage, ±2% accuracy, 8-DIP Module package, and -20°C ~ 105°C operating temperature. The pressure type differs (vented gauge versus differential), which may affect performance in applications requiring specific pressure measurement methodology. Electrical signal compatibility is maintained.

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

A: ASDXRRX001PGAA5 operates at 1PSI (6.89kPa) with a maximum pressure of 2PSI (13.79kPa), compared to the ASDX030D44R specification of 30PSI operating pressure and 60PSI maximum pressure. This 30-fold difference in pressure rating restricts application to low-pressure measurement scenarios only. Electrical output characteristics remain identical, but pressure range incompatibility prevents use in applications requiring 30PSI measurement capability.

Q: Are there any compatibility concerns with the tube port dimensions?

A: The ASDX030D44R specifies male 0.09" (2.29mm) tube ports, while both substitute parts specify male 0.09" (2.31mm) tube ports. This 0.02mm dimensional difference is within typical manufacturing tolerance for barbed tube connectors and does not prevent mechanical compatibility. Both configurations use barbless port style and dual tube configuration.

Q: What is the significance of the product status change from Obsolete to Active?

A: The ASDX030D44R is classified as obsolete, indicating discontinued production. ASDXRRX030PGAA5 and ASDXRRX001PGAA5 are both in active production status, ensuring continued availability, technical support, and supply chain reliability. Active status supports long-term system maintenance and future procurement requirements.

Q: Are both substitute parts RoHS compliant?

A: Yes. ASDXRRX030PGAA5 and ASDXRRX001PGAA5 are both RoHS Compliant, matching the compliance status of the ASDX030D44R. This ensures regulatory alignment for applications subject to RoHS requirements.
