DUXL10D Equivalent & Substitute Parts Reference

Part Overview

The DUXL10D is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement. This 4-SIP module sensor outputs analog voltage signals in the 0 mV to 30 mV range and operates across a temperature range of -25°C to 85°C. The product is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing system support, maintenance, and new design implementations where equivalent performance specifications are required.

Substitute Part Grouping Explanation

Substitution eligibility for the DUXL10D is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Pressure Type: Differential
Operating Pressure: 0.36 PSI (2.49 kPa)
Output Range: 0 mV ~ 30 mV (4.5V)
Package Type: 4-SIP Module
Mounting Type: Through Hole
Termination Style: PC Pin
Operating Temperature Range: -25°C ~ 85°C
Accuracy: ±0.5%

Allowable Variations:

Port Size: Tube diameter tolerance of ±0.10" (2.03 mm to 2.13 mm) is acceptable for barbed and barbless port styles
Supply Voltage: Substitute must operate within or encompass the 3V ~ 8V range
Output Type: Both Wheatstone Bridge and Analog Voltage outputs are functionally equivalent for this pressure range and signal level
RoHS Compliance: May differ from original specification

The 10 INCH-D1-BASIC from Amphenol All Sensors Corporation meets all mandatory matching parameters and qualifies as a direct substitute.

Engineering Selection Recommendations

The 10 INCH-D1-BASIC qualifies as a direct substitute for the DUXL10D based on matching pressure specifications, output signal characteristics, package configuration, and operating parameters. The substitute part is in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete DUXL10D.

Compliance Consideration: The DUXL10D is RoHS compliant while the 10 INCH-D1-BASIC is RoHS non-compliant. Applications subject to RoHS regulatory requirements must evaluate this difference against system-level compliance obligations.

Port Configuration: The tube diameter difference of 0.10 mm (2.03 mm versus 2.13 mm) falls within standard manufacturing tolerances for barbed and barbless connector interfaces. Both configurations accommodate standard 0.08" tubing connections.

Supply Voltage: The 10 INCH-D1-BASIC operates at a fixed 6V supply, which is within the DUXL10D's 3V to 8V operating range. System designs must confirm that 6V supply voltage is available or implement appropriate voltage regulation.

Frequently Asked Questions (FAQ)

Q: Can the 10 INCH-D1-BASIC directly replace the DUXL10D in existing circuit designs?

A: Yes. Both sensors share identical pressure measurement range (0.36 PSI), output signal levels (0 mV to 30 mV at 4.5V), package type (4-SIP Module), and pin termination style (PC Pin). The 6V fixed supply voltage of the substitute is compatible with the DUXL10D's 3V to 8V operating range. No circuit modifications are required for pressure measurement functionality.

Q: What is the difference between Wheatstone Bridge and Analog Voltage output types?

A: Both output types deliver equivalent signal information for this pressure range. The Wheatstone Bridge configuration in the DUXL10D and the Analog Voltage output in the 10 INCH-D1-BASIC both produce 0 mV to 30 mV signals proportional to the applied differential pressure. Signal conditioning and interface requirements remain identical.

Q: Does the port style difference (barbed versus barbless) affect compatibility?

A: Port style does not affect pressure measurement compatibility. Barbed ports provide mechanical retention through friction fit, while barbless ports rely on external clamping. Tubing connection methods may differ, but both styles accommodate standard 0.08" tubing. Verify mechanical installation requirements for your specific application.

Q: Why is RoHS compliance different between these parts?

A: The DUXL10D was manufactured to RoHS specifications, while the 10 INCH-D1-BASIC predates or does not meet RoHS requirements. Applications subject to RoHS directives (EU 2011/65/EU or equivalent) must confirm that non-compliant substitutes are acceptable under system-level exemptions or regulatory scope.

Q: Is the 0.10 mm tube diameter difference significant?

A: No. The difference between 2.03 mm and 2.13 mm falls within standard manufacturing tolerances for barbed and barbless tubing connectors. Both configurations are designed to interface with 0.08" (2.032 mm) nominal tubing.

Q: What is the availability status of these parts?

A: The DUXL10D is obsolete with 952 units in current inventory. The 10 INCH-D1-BASIC is in active production with 647 units available, ensuring continued supply for future requirements and system maintenance.
