DUXL30D Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The DUXL30D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement. This sensor outputs a Wheatstone Bridge signal in the range of 0 mV to 30 mV at 4.5V supply, with a measurement range of 1.08 PSI (7.48 kPa) differential pressure.

The DUXL30D is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DUXL30D is determined by the following critical parameters:

Pressure Measurement Capability: The substitute must measure the same differential pressure range of 1.08 PSI (7.48 kPa).

Output Signal Characteristics: The substitute must produce a Wheatstone Bridge output signal within the 0 mV to 30 mV range at the specified supply voltage.

Electrical Compatibility: The substitute must operate within the supply voltage range of 3V to 8V and maintain the same output accuracy of ±0.5%.

Physical Interface: The substitute must feature a 4-SIP module package with PC pin termination for through-hole mounting on printed circuit boards.

Environmental Performance: The substitute must maintain operational specifications across the temperature range of -25°C to 85°C.

Port Configuration: The substitute must accommodate dual male tube connections for differential pressure measurement.

The 30 INCH-D1-BASIC manufactured by Amphenol All Sensors Corporation meets these substitution criteria.

Parameter Comparison

Engineering Selection Recommendations

The 30 INCH-D1-BASIC is functionally equivalent to the DUXL30D for applications requiring differential pressure measurement at 1.08 PSI with Wheatstone Bridge output.

Product Status Consideration: The DUXL30D is obsolete, while the 30 INCH-D1-BASIC is active. Selection of the active part ensures continued availability and supply chain support.

Compliance Difference: The DUXL30D is RoHS compliant, while the 30 INCH-D1-BASIC is RoHS non-compliant. Applications subject to RoHS regulatory requirements must account for this distinction in component selection.

Supply Voltage: The 30 INCH-D1-BASIC operates at a fixed 6V supply, which falls within the DUXL30D's 3V to 8V operating range. System designs must confirm that 6V supply voltage is available or can be provided.

Port Configuration: The 30 INCH-D1-BASIC features barbless tube connections compared to the barbed configuration of the DUXL30D. Both configurations accommodate dual male tube connections for differential pressure measurement. Tubing compatibility must be verified based on the specific tube outer diameter and connection method used in the target application.

Temperature Compensation: The 30 INCH-D1-BASIC includes temperature compensation, which is not specified for the DUXL30D. This feature may provide improved measurement stability across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the 30 INCH-D1-BASIC directly replace the DUXL30D in existing designs?

A: The 30 INCH-D1-BASIC is functionally equivalent for differential pressure measurement, output signal type, and package configuration. Direct replacement is possible if the application can accommodate the fixed 6V supply voltage and barbless tube connection style. Tubing compatibility must be verified based on the specific tube dimensions and connection requirements of the original design.

Q: What is the significance of the barbed versus barbless port configuration?

A: Barbed ports feature small barbs that grip tubing to prevent disconnection through friction. Barbless ports rely on external fastening or compression fittings. The choice between these configurations depends on the tubing type and connection method specified in the application. Both configurations support dual male tube connections for differential pressure measurement.

Q: Does the RoHS non-compliance of the 30 INCH-D1-BASIC affect its use?

A: RoHS compliance is a regulatory requirement for products sold in certain markets, particularly the European Union. Applications subject to RoHS regulations must use RoHS-compliant components. Applications without RoHS requirements may use the 30 INCH-D1-BASIC without regulatory restriction.

Q: Are there differences in measurement accuracy between these parts?

A: Both the DUXL30D and 30 INCH-D1-BASIC specify ±0.5% accuracy. The 30 INCH-D1-BASIC includes temperature compensation, which may improve measurement stability across temperature variations, though both parts operate across the same -25°C to 85°C temperature range.

Q: What supply voltage should be used with the 30 INCH-D1-BASIC?

A: The 30 INCH-D1-BASIC operates at 6V. The DUXL30D operates across a 3V to 8V range. System designs must provide 6V supply voltage for the substitute part. Confirm that the application's power supply can deliver 6V before implementing this substitution.

Q: Are the 4-SIP module packages physically identical?

A: Both parts use 4-SIP module packages with PC pin termination for through-hole mounting. The physical footprint and pin configuration are compatible for PCB mounting. Verify PCB layout compatibility before implementation.
