ASDX030D44R-DO Pressure Sensor Equivalent & Substitute Parts

Part Overview

The ASDX030D44R-DO is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 30PSI (206.84kPa) differential pressure measurement with 12-bit digital output via I2C interface. This component operates within a -20°C to 105°C temperature range and features temperature compensation for enhanced accuracy.

The ASDX030D44R-DO is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ASDX030D44R-DO is constrained by the following critical parameters that must align between the main part and any substitute:

Mandatory Alignment Parameters:

• Manufacturer: Honeywell Sensing and Productivity Solutions (ASDX series)
• Package Type: 8-DIP Module
• Mounting Type: Through Hole
• Port Style: Barbless
• Supply Voltage Range: 4.75V ~ 5.25V
• Operating Temperature Range: -20°C ~ 105°C
• Accuracy: ±2%
• Termination Style: PC Pin

Application-Specific Parameters: The ASDX030D44R-DO operates as a differential pressure sensor with I2C digital output and 12-bit resolution. Substitutes must maintain compatibility with these output characteristics and pressure measurement type to function within existing circuit designs.

The identified substitute part ASDXRRX001PGAA5 shares the same manufacturer, series, package, mounting type, port style, supply voltage, operating temperature range, accuracy, and termination style. However, this part operates as a vented gauge pressure sensor with analog voltage output (0.5V ~ 4.5V) rather than differential pressure with I2C output, representing a functional divergence that requires circuit-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The ASDX030D44R-DO is classified as obsolete, while ASDXRRX001PGAA5 maintains active product status with Honeywell. Active status indicates ongoing manufacturing support, documented supply chain availability, and continued technical support from the manufacturer.

Compliance and Certification: Both parts maintain RoHS Compliance and MSL Rating 1 (Unlimited), indicating equivalent environmental and moisture handling requirements. Both are classified under ECCN EAR99 and HTSUS 9026.20.4000, confirming regulatory alignment.

Functional Compatibility: Direct substitution of ASDXRRX001PGAA5 for ASDX030D44R-DO requires circuit redesign. The main part provides differential pressure measurement at 30PSI with I2C digital output, while the substitute provides vented gauge pressure measurement at 1PSI with analog voltage output. These represent distinct measurement types and output protocols that cannot function interchangeably without signal conditioning and interface modification.

Selection Basis: Selection between these parts must be based on application requirements for pressure type (differential versus vented gauge), pressure range (30PSI versus 1PSI), and output interface (I2C digital versus analog voltage). The substitute part is suitable only for applications requiring lower pressure measurement with analog signal processing.

Frequently Asked Questions (FAQ)

Q: Can ASDXRRX001PGAA5 directly replace ASDX030D44R-DO in existing designs?

A: No. While both parts share the same manufacturer, series, package, and mounting characteristics, they differ in pressure type (differential versus vented gauge), operating pressure range (30PSI versus 1PSI), and output interface (I2C digital versus analog voltage). Direct substitution requires circuit redesign and signal processing modifications.

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

A: Differential pressure sensors measure the pressure difference between two independent pressure inputs. Vented gauge pressure sensors measure pressure relative to atmospheric pressure through a vent port. These measurement types serve different applications and cannot be interchanged without system redesign.

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

A: The port sizes are nominally equivalent (0.09" tube, dual male barbless configuration), with a minor dimensional variation (2.29mm versus 2.31mm). Physical port compatibility exists, but pressure type and measurement range differences prevent functional substitution.

Q: What is the significance of the active product status for ASDXRRX001PGAA5?

A: Active product status indicates that Honeywell continues manufacturing, supporting, and documenting this component. This ensures supply chain availability, technical support, and design documentation continuity for new designs or production maintenance.

Q: Can the analog voltage output of ASDXRRX001PGAA5 be converted to I2C for compatibility?

A: Conversion would require external signal conditioning and analog-to-digital conversion circuitry. This approach introduces additional components, cost, and design complexity. Such modifications fall outside the scope of direct component substitution.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -20°C to 105°C with temperature compensation, providing equivalent thermal performance characteristics.

Q: What inventory considerations exist for these parts?

A: ASDX030D44R-DO has 949 pieces available as new original stock. ASDXRRX001PGAA5 has 2580 pieces available as new original stock. The substitute part offers greater inventory availability, supporting supply chain continuity for active production.
