ASDX005G24R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX005G24R-DO is a vented gauge pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This 12-bit digital pressure sensor operates at 5PSI (34.47kPa) with I2C output and is housed in an 8-DIP through-hole package. The device is currently classified as obsolete, necessitating identification of equivalent substitute components for ongoing applications and new designs requiring similar pressure measurement capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX005G24R-DO is constrained by the following critical parameters:

Output Interface Compatibility: The main part features I2C digital output (12-bit), while the identified substitute operates with analog voltage output (0.5V ~ 4.5V). This represents a fundamental difference in signal transmission and requires circuit-level modifications.

Operating Pressure Range: The main part is rated for 5PSI (34.47kPa) operating pressure with a maximum of 20PSI (137.9kPa). The substitute operates at 1PSI (6.89kPa) with a maximum of 2PSI (13.79kPa). This pressure range differential restricts direct substitution to applications with lower pressure requirements.

Port Configuration: Both components feature male barbless tube ports at 0.09" diameter, with the substitute offering dual port configuration versus the main part's single top port.

Shared Parameters Enabling Substitution: Both components maintain identical supply voltage range (4.75V ~ 5.25V), accuracy specification (±2%), operating temperature range (-20°C ~ 105°C), temperature compensation, RoHS compliance, and 8-DIP through-hole mounting. Both belong to the ASDX series from Honeywell.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility: The ASDXRRX001PGAA5 is not a direct pin-for-pin replacement due to fundamental differences in output interface and pressure rating. Direct substitution requires circuit redesign to accommodate analog voltage output instead of I2C digital output.

Product Status Consideration: The ASDX005G24R-DO is classified as obsolete, while the ASDXRRX001PGAA5 maintains active production status. For new designs or long-term supply assurance, the active substitute is preferable from a component lifecycle perspective.

Compliance and Certification: Both components maintain identical RoHS compliance status and operate within the same supply voltage and temperature specifications, supporting functional equivalence in these regulatory and environmental aspects.

Application Scope: Substitution is limited to applications where the lower operating pressure range (1PSI maximum versus 5PSI nominal) is acceptable and where analog voltage output can be integrated into the system architecture.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDX005G24R-DO in existing designs?

A: No. While both components share the same 8-DIP through-hole package and mounting footprint, the output interface differs fundamentally. The main part outputs I2C digital signals (12-bit), while the substitute outputs analog voltage (0.5V ~ 4.5V). Circuit modifications are required to accommodate this interface change.

Q: What is the primary limitation for substitution?

A: The operating pressure rating is the primary limitation. The ASDXRRX001PGAA5 is rated for 1PSI (6.89kPa) operating pressure with a 2PSI maximum, compared to the main part's 5PSI operating and 20PSI maximum. Substitution is only viable for applications requiring lower pressure measurement.

Q: Are the port connections compatible?

A: Both components feature male barbless tube ports at 0.09" diameter. The substitute offers dual port configuration versus the main part's single top port. Mechanical connection is compatible, though the dual-port design may require different manifold or tubing arrangements.

Q: What are the supply voltage requirements?

A: Both components require identical supply voltage of 4.75V ~ 5.25V. No power supply modifications are necessary for substitution.

Q: Is the ASDXRRX001PGAA5 suitable for new designs?

A: Yes. The substitute is in active production status, ensuring long-term availability. However, the lower pressure rating and analog output interface must align with application requirements.

Q: Do both components operate across the same temperature range?

A: Yes. Both the main part and substitute operate from -20°C to 105°C with temperature compensation, providing identical thermal performance specifications.

Q: What accuracy can be expected from the substitute?

A: The ASDXRRX001PGAA5 maintains the same ±2% accuracy specification as the main part, ensuring equivalent measurement precision within the lower pressure operating range.
