ASDX005D44D-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX005D44D-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 device 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 legacy system maintenance, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX005D44D-DO is constrained by the following critical parameters:

Pressure Measurement Characteristics: The main part measures differential pressure at 5PSI operating range with 12-bit digital resolution via I2C output. Substitute parts must maintain compatibility with the application's pressure measurement requirements and signal interface expectations.

Electrical Interface: The ASDX005D44D-DO operates on 4.75V to 5.25V supply voltage with I2C digital output. Substitute components must support identical or compatible supply voltage ranges and output protocols to integrate with existing circuit designs without modification.

Physical Form Factor: The 8-DIP Module package with through-hole termination and PC pin configuration defines the mechanical compatibility. Port configuration (Male - 0.09" Tube, Dual, Barbless) must match to ensure pneumatic connection compatibility.

Environmental Specifications: Operating temperature range (-20°C to 105°C), temperature compensation, and accuracy (±2%) establish the performance envelope for substitution candidates.

Compliance and Status: RoHS compliance and MSL rating must be maintained for regulatory and manufacturing process compatibility.

The substitute part ASDXRRX001PGAA5 shares the same manufacturer, series, package type, port configuration, accuracy specification, supply voltage range, operating temperature range, and compliance certifications. However, it differs in pressure type (vented gauge vs. differential), operating pressure range (1PSI vs. 5PSI), output type (analog voltage vs. I2C), and output format (0.5V ~ 4.5V vs. 12-bit digital).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASDX005D44D-DO is classified as obsolete. The substitute part ASDXRRX001PGAA5 carries active product status, indicating ongoing manufacturer support and availability.

Compliance Alignment: Both parts maintain RoHS compliance and identical MSL ratings, ensuring regulatory and manufacturing process compatibility.

Substitution Feasibility: Direct substitution of ASDXRRX001PGAA5 for ASDX005D44D-DO is not recommended without application-level review. The substitute part differs in three critical functional parameters: pressure type (vented gauge vs. differential), operating pressure range (1PSI vs. 5PSI), and output interface (analog voltage vs. I2C digital). These differences require circuit redesign and firmware modification to accommodate the alternative signal format and pressure measurement methodology.

Mechanical Compatibility: Both parts share identical package form factors, mounting types, and port configurations (8-DIP Module, through-hole, barbless male tube ports). Pneumatic connection compatibility is maintained within the specified tube diameter tolerances.

Selection Path: For applications requiring differential pressure measurement with I2C output at 5PSI operating range, alternative ASDX series components with matching functional specifications should be evaluated. For applications where vented gauge pressure measurement at 1PSI range with analog voltage output is functionally acceptable, ASDXRRX001PGAA5 provides an active-status alternative with equivalent environmental and compliance specifications.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX001PGAA5 directly replace ASDX005D44D-DO in existing designs?

A: No. While both parts share the same manufacturer, series, package type, and environmental specifications, they differ in pressure measurement type, operating pressure range, and output interface. Direct replacement requires circuit redesign to accommodate analog voltage output instead of I2C digital output, and application logic must be adapted for vented gauge pressure measurement instead of differential pressure measurement.

Q: What are the key differences between differential and vented gauge pressure types?

A: Differential pressure measurement compares pressure between two independent ports and outputs the difference. Vented gauge pressure measurement compares pressure at one port against atmospheric pressure vented through a second port. These measurement methodologies produce different output values for identical physical pressure conditions and require different application logic.

Q: Are the port sizes compatible between these two parts?

A: The port sizes are nominally compatible. ASDX005D44D-DO specifies 0.09" (2.29mm) tube diameter, while ASDXRRX001PGAA5 specifies 0.09" (2.31mm) tube diameter. Both use barbless male tube connectors with dual ports. The 0.02mm difference falls within standard tubing tolerance ranges and does not prevent physical connection.

Q: What is the significance of the product status difference?

A: ASDX005D44D-DO is classified as obsolete, indicating the manufacturer no longer produces or supports this part. ASDXRRX001PGAA5 is classified as active, indicating ongoing production and manufacturer support. For new designs or long-term procurement, active-status parts provide supply chain continuity and technical support advantages.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are RoHS compliant and carry MSL rating 1 (Unlimited), indicating identical regulatory compliance and manufacturing process compatibility. Both are classified under ECCN EAR99 and HTSUS 9026.20.4000.

Q: What output signal modifications would be required to use ASDXRRX001PGAA5 instead of ASDX005D44D-DO?

A: The main part outputs 12-bit digital data via I2C protocol. The substitute part outputs analog voltage in the range 0.5V to 4.5V. Integration would require removal of I2C signal conditioning circuitry and implementation of analog-to-digital conversion with appropriate voltage scaling and offset calibration to match the original 12-bit resolution and pressure range mapping.
