ASDX005D44R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX005D44R-DO is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 5PSI (34.47kPa) differential pressure measurement with 12-bit digital output via I2C interface. The sensor features temperature compensation and operates across an industrial temperature range of -20°C to 105°C.

This part is classified as obsolete. Identifying equivalent and substitute components is necessary to support ongoing system maintenance, design updates, and procurement continuity where the original part is no longer available from primary sources.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX005D44R-DO is constrained by the following critical parameters that must align between the original and substitute component:

Mandatory Alignment Parameters:

• Manufacturer series (ASDX family)
• Package type (8-DIP Module)
• Mounting configuration (Through Hole, PC Pin termination)
• Supply voltage range (4.75V ~ 5.25V)
• Operating temperature range (-20°C ~ 105°C)
• Accuracy specification (±2%)
• Port configuration (Male, Barbless, Dual tube)
• RoHS compliance status

Variable Parameters (Substitution Allowed):

• Pressure type (Differential vs. Vented Gauge)
• Operating pressure rating
• Output interface (I2C vs. Analog Voltage)
• Output resolution or signal range
• Maximum pressure rating

The ASDXRRX001PGAA5 is identified as a substitute part within the ASDX series. However, this substitute introduces significant functional differences in pressure type, output interface, and pressure rating that must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASDX005D44R-DO is obsolete, while the ASDXRRX001PGAA5 maintains active production status. This distinction is significant for long-term supply chain planning and component availability.

Compliance Alignment: Both components are RoHS Compliant and carry identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory equivalence for export and procurement purposes.

Functional Substitution Constraints: The ASDXRRX001PGAA5 cannot serve as a direct functional replacement for the ASDX005D44R-DO due to three critical differences:

1. Pressure Type Mismatch: The main part measures differential pressure; the substitute measures vented gauge pressure. These are fundamentally different measurement modes requiring different sensor configurations and application contexts.

2. Output Interface Incompatibility: The main part provides I2C digital output; the substitute provides analog voltage output (0.5V ~ 4.5V). Systems designed for I2C communication cannot directly interface with analog voltage output without additional signal conditioning circuitry.

3. Pressure Rating Divergence: The main part operates at 5PSI with a maximum of 20PSI; the substitute operates at 1PSI with a maximum of 2PSI. Applications requiring higher pressure measurement capability cannot use the lower-rated substitute.

Recommendation Basis: Selection of the ASDXRRX001PGAA5 as a substitute is only appropriate when the application requirements align with vented gauge pressure measurement, analog voltage signal processing, and the lower 1PSI operating pressure specification. Direct substitution without application redesign is not supported by the provided parameters.

Frequently Asked Questions (FAQ)

Q: Can the ASDXRRX001PGAA5 directly replace the ASDX005D44R-DO in an existing circuit?

A: No. The ASDXRRX001PGAA5 has a different output interface (analog voltage vs. I2C), different pressure type (vented gauge vs. differential), and different pressure rating (1PSI vs. 5PSI). Direct substitution requires circuit redesign and signal processing modifications.

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

A: Differential pressure measurement compares pressure between two separate ports. Vented gauge pressure measures pressure relative to atmospheric pressure through a single vented port. These are distinct measurement modes for different applications.

Q: Are the physical packages identical between these two parts?

A: Both parts use 8-DIP Module packages with Through Hole mounting and PC Pin termination. Port configurations are functionally equivalent (Male, Barbless, Dual tube). Physical footprint compatibility exists, but functional compatibility does not.

Q: Why is the ASDX005D44R-DO listed as obsolete?

A: Product status reflects manufacturer production decisions. Obsolete status indicates the part is no longer manufactured. The ASDXRRX001PGAA5 remains in active production within the same ASDX series.

Q: What supply voltage do both parts require?

A: Both the ASDX005D44R-DO and ASDXRRX001PGAA5 require identical supply voltage of 4.75V ~ 5.25V, ensuring power supply compatibility.

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

A: Yes. Both components operate from -20°C to 105°C with temperature compensation, providing equivalent thermal performance specifications.

Q: What accuracy specification applies to both parts?

A: Both parts maintain ±2% accuracy, ensuring equivalent measurement precision within their respective pressure ranges.

Q: Can I use the ASDXRRX001PGAA5 if my application only requires 1PSI measurement?

A: The ASDXRRX001PGAA5 is rated for 1PSI operating pressure with a 2PSI maximum. If your application requires differential pressure measurement with I2C output, this substitute does not meet those functional requirements regardless of pressure magnitude.
