DCXL01DS Pressure Sensor Equivalent & Substitute Parts

Part Overview

The DCXL01DS 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 10 mV at 12V supply, with a measurement range of 0.04 PSI (0.25 kPa) differential pressure.

The DCXL01DS 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 currently utilizing this component.

Substitute Part Grouping Explanation

Substitution of the DCXL01DS is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

Pressure Type: Differential
Operating Pressure: 0.04 PSI (0.25 kPa)
Output Type: Wheatstone Bridge
Output Range: 0 mV ~ 10 mV (12V)
Accuracy: ±0.25%
Port Size: Male - 0.19" (4.83 mm) Tube, Dual
Operating Temperature: -25°C ~ 85°C
Package Type: 6-SIP Module
Mounting Type: Through Hole
Termination Style: PC Pin
Temperature Compensation: Required

Allowable Parameter Variations:

Voltage Supply: Substitute must support the 12V nominal operating point; range variations within 3V ~ 16V are acceptable
Port Style: Barbed or barbless configurations are functionally equivalent for tube connection applications
Maximum Pressure Rating: Substitute may differ from the original specification
Product Status: Active status is preferred for ongoing availability

The substitute part 1 INCH-D-MV meets all mandatory matching parameters and is therefore classified as a direct equivalent.

Engineering Selection Recommendations

The 1 INCH-D-MV manufactured by Amphenol All Sensors Corporation is a direct substitute for the DCXL01DS. Selection of this substitute is supported by the following engineering factors:

Functional Equivalence: All critical electrical and mechanical parameters match the original specification. The sensor provides identical pressure measurement range, output signal characteristics, accuracy, and operating temperature range.

Product Status Advantage: The 1 INCH-D-MV maintains active product status, ensuring continued availability and supply chain support. The DCXL01DS is obsolete, making the substitute the preferred choice for new designs and ongoing production.

Compliance Status: Both components are RoHS compliant. The 1 INCH-D-MV carries ROHS3 compliance, meeting current regulatory requirements. Both components are classified as EAR99 for export control purposes.

Port Configuration: The barbless port style of the 1 INCH-D-MV is functionally equivalent to the barbed configuration of the DCXL01DS for tube connection applications. Both configurations provide secure mechanical attachment to 0.19" (4.83 mm) tubing.

Voltage Supply Specification: The 1 INCH-D-MV is specified for 16V supply, which falls within the acceptable operating range for 12V nominal applications. The original DCXL01DS supports a broader supply range (3V ~ 16V); however, the substitute operates reliably at the 12V nominal point required by the application.

Maximum Pressure Rating: The 1 INCH-D-MV has a lower maximum pressure rating (3.61 PSI) compared to the DCXL01DS (5 PSI). This variation is allowable because the operating pressure specification (0.04 PSI) remains identical, and the substitute's maximum rating provides adequate safety margin for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the 1 INCH-D-MV be used as a direct replacement for the DCXL01DS in existing designs?

A: Yes. The 1 INCH-D-MV is a direct substitute. All critical electrical parameters, mechanical dimensions, package type, and mounting configuration are identical. The component can be substituted without circuit redesign or PCB modification.

Q: What is the difference between barbed and barbless port styles?

A: Barbed ports feature small barbs that grip tubing from the inside, while barbless ports rely on compression fitting. Both styles provide secure attachment to 0.19" (4.83 mm) tubing. The choice between them depends on the tubing material and connection method used in the application. For most standard tube connections, both are functionally equivalent.

Q: Why does the 1 INCH-D-MV have a lower maximum pressure rating than the DCXL01DS?

A: Maximum pressure rating indicates the highest pressure the sensor can withstand without damage. The operating pressure specification (0.04 PSI) defines the normal measurement range. The 1 INCH-D-MV's maximum rating of 3.61 PSI provides adequate safety margin above the 0.04 PSI operating point. The lower rating does not affect performance within the specified operating range.

Q: Is the voltage supply difference between the two sensors a concern?

A: No. The DCXL01DS supports a supply range of 3V ~ 16V, while the 1 INCH-D-MV is specified for 16V. Both sensors operate at the 12V nominal point required by typical applications. The substitute's fixed 16V specification is compatible with 12V operation.

Q: What is the inventory status of these components?

A: The DCXL01DS has 8,662 pieces in stock but is classified as obsolete. The 1 INCH-D-MV has 1,247 pieces in stock and maintains active product status, ensuring continued availability for future orders.

Q: Are there any compliance or certification differences between the two sensors?

A: Both sensors are RoHS compliant and classified as EAR99 for export control. The 1 INCH-D-MV carries ROHS3 compliance, which represents the current regulatory standard. Both components are unaffected by REACH regulations.

Q: Can the 1 INCH-D-MV be used in applications requiring the full 3V ~ 16V supply range of the DCXL01DS?

A: The 1 INCH-D-MV is specified for 16V operation. Applications requiring operation below 16V should be evaluated based on the specific voltage requirements. For standard 12V applications, the substitute is fully compatible.
