DCXL05DS Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DCXL05DS 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 0 mV to 20 mV signal proportional to a 0.18 PSI (1.25 kPa) differential pressure range, with dual barbed male tube ports of 0.19" (4.83 mm) diameter. The DCXL05DS operates from a 3V to 16V supply and features temperature compensation with ±0.25% accuracy.

The DCXL05DS is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality and ensure continued availability for applications currently using this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCXL05DS is determined by strict alignment of the following critical parameters:

Pressure Measurement Specifications: The substitute must measure differential pressure at 0.18 PSI (1.25 kPa) operating range with Wheatstone Bridge output topology and 0 mV to 20 mV output signal.

Electrical Compatibility: The substitute must operate within the 3V to 16V supply voltage range and deliver the same output signal characteristics at 12V nominal supply.

Mechanical Interface: The substitute must feature dual male barbed tube ports of 0.19" (4.8 mm) diameter to ensure direct connection compatibility with existing tubing and manifold assemblies.

Package and Termination: The substitute must be housed in a 6-SIP module with PC pin termination for through-hole board mounting.

Environmental Performance: The substitute must maintain ±0.25% accuracy across the -25°C to 85°C operating temperature range with temperature compensation.

The 5 INCH-D-MV from Amphenol All Sensors Corporation meets all these criteria and is classified as an active product.

Engineering Selection Recommendations

The 5 INCH-D-MV is a direct functional substitute for the obsolete DCXL05DS based on the following engineering criteria:

Product Status: The DCXL05DS is obsolete, while the 5 INCH-D-MV is active. Selection of the active product ensures long-term availability and supply chain continuity.

Regulatory Compliance: Both sensors are RoHS compliant. The 5 INCH-D-MV carries ROHS3 compliance and REACH Unaffected status, meeting current environmental and regulatory requirements.

Electrical and Functional Equivalence: Both sensors deliver identical pressure measurement performance, output signal characteristics, accuracy, and operating temperature range. The 5 INCH-D-MV operates at a fixed 16V supply, which falls within the DCXL05DS supply range of 3V to 16V, ensuring compatibility with existing power supplies.

Mechanical Interface: Both sensors feature 6-SIP module packaging with PC pin through-hole termination. The port diameter difference (4.83 mm versus 4.8 mm) is negligible for tubing compatibility. The port style difference (barbed versus barbless) requires evaluation of the specific tubing connection method in the application.

Performance Margin: The 5 INCH-D-MV provides a higher maximum pressure rating (7.23 PSI versus 5 PSI), offering additional safety margin in applications subject to transient overpressure conditions.

Frequently Asked Questions (FAQ)

Q: Can the 5 INCH-D-MV directly replace the DCXL05DS without circuit modifications?

A: Yes. Both sensors output 0 mV to 20 mV from a Wheatstone Bridge at 12V nominal supply. The 5 INCH-D-MV operates at 16V fixed supply, which is within the DCXL05DS supply range. No signal conditioning or circuit changes are required.

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

A: The DCXL05DS features barbed ports; the 5 INCH-D-MV features barbless ports. Barbed ports provide mechanical retention for push-fit tubing connections. Barbless ports require alternative connection methods such as compression fittings or hose clamps. Evaluate your existing tubing connection hardware before substitution.

Q: Are both sensors suitable for the same pressure range applications?

A: Yes. Both sensors measure 0.18 PSI (1.25 kPa) differential pressure with identical accuracy (±0.25%). The 5 INCH-D-MV has a higher maximum pressure rating (7.23 PSI versus 5 PSI), making it suitable for applications with higher transient pressure spikes.

Q: What are the compliance differences between the two sensors?

A: The DCXL05DS is RoHS Compliant. The 5 INCH-D-MV is ROHS3 Compliant and REACH Unaffected. ROHS3 represents the current RoHS directive standard. Both meet environmental compliance requirements for new designs and applications.

Q: Is the 0.03 mm port diameter difference (4.83 mm versus 4.8 mm) significant?

A: No. This difference is within standard manufacturing tolerance and does not affect tubing compatibility or functional performance.

Q: Can I use the 5 INCH-D-MV in applications currently using the DCXL05DS?

A: Yes, provided the tubing connection method is compatible with barbless ports. Verify that your application uses compression fittings, hose clamps, or other connection methods suitable for barbless ports, or adapt the connection hardware accordingly.
