DCXL30DS Equivalent & Substitute Parts Reference

Part Overview

The DCXL30DS is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 1.08PSI (7.48kPa) operating pressure range. The sensor features a Wheatstone Bridge output of 0 mV ~ 20 mV at 12V supply, with male barbed tube ports of 0.19" (4.83mm) diameter in a 6-SIP module configuration. The product is classified as obsolete, necessitating identification of equivalent and substitute components for ongoing system support and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DCXL30DS is determined by the following critical parameters: differential pressure type, operating pressure range of 1.08PSI (7.48kPa), output signal characteristics, port configuration (male 0.19" dual tubes), through-hole mounting, and operating temperature range. Substitute parts must maintain compatibility with these core specifications to ensure functional equivalence in existing applications.

The substitute parts are grouped into two categories:

Similar Substitutes (Functional Equivalents with Design Differences): Parts that maintain the same differential pressure range and port configuration but employ different output technologies or package formats. These require circuit-level evaluation for compatibility.

Direct Equivalent (Pin and Functional Compatible): Parts that provide identical or superior specifications with direct replacement capability in the same application context.

Parameter Comparison

Engineering Selection Recommendations

30 INCH-D-MV (Amphenol All Sensors Corporation): This part provides the closest functional equivalence to the DCXL30DS. Both sensors share identical differential pressure specifications (1.08PSI / 7.48kPa), Wheatstone Bridge output topology (0 mV ~ 20 mV at 12V), 6-SIP module packaging, and barbed port configuration. The 30 INCH-D-MV is currently in active production status with ROHS3 compliance certification. This part is suitable for direct replacement in applications where the DCXL30DS is currently deployed, provided PCB layout accommodates the barbless port style transition.

TSCSNBN001PDUCV (Honeywell TruStability TSC Series): This substitute maintains Wheatstone Bridge output technology and operates within the same pressure range (±1PSI / ±6.89kPa). The part features improved accuracy (±0.2% versus ±0.25%), extended operating temperature range (-40°C to 85°C), and active product status. However, the output signal is reduced to 0 mV ~ 15 mV at 5V supply, requiring signal conditioning circuit modifications. The 4-SIP package differs from the original 6-SIP configuration, necessitating PCB redesign. This option is suitable for new designs or applications where circuit modification is feasible.

SSCSNBN030NDAA5 (Honeywell TruStability SSC Series): This part matches the differential pressure specification (±1.08PSI / ±7.48kPa) and maintains dual 0.19" port configuration. The sensor employs amplified analog voltage output (0.5 V ~ 4.5 V) rather than Wheatstone Bridge topology, requiring complete signal processing redesign. The 4-SIP package and barbless port style necessitate PCB layout modifications. This option is recommended only for new system designs where the amplified output topology provides system-level advantages.

All substitute parts maintain RoHS compliance and temperature compensation features. Selection should prioritize the 30 INCH-D-MV for direct replacement scenarios due to functional and packaging equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 30 INCH-D-MV directly replace the DCXL30DS without circuit modifications?

A: The 30 INCH-D-MV provides functional equivalence in output signal type (Wheatstone Bridge), voltage range (0 mV ~ 20 mV at 12V), and pressure specifications (1.08PSI differential). Both parts feature 6-SIP module packaging and through-hole mounting. The primary difference is port style (barbless versus barbed), which affects tubing connection method but not electrical compatibility. PCB layout verification is required to confirm pin-to-pin compatibility.

Q: What are the key differences between Wheatstone Bridge and amplified analog voltage outputs?

A: The DCXL30DS and 30 INCH-D-MV employ Wheatstone Bridge output, which requires external signal conditioning and amplification circuitry to convert the low-level mV signal to usable voltage levels. The SSCSNBN030NDAA5 provides amplified analog voltage output (0.5 V ~ 4.5 V), eliminating the need for external amplification but requiring different signal processing. Wheatstone Bridge outputs offer higher resolution and lower noise in properly designed circuits, while amplified outputs provide simplified integration at the cost of reduced signal resolution.

Q: Are the port configurations compatible between these sensors?

A: All substitute parts feature male 0.19" (4.8mm to 4.83mm) dual tube ports. The DCXL30DS and 30 INCH-D-MV use barbed ports, while TSCSNBN001PDUCV and SSCSNBN030NDAA5 use barbless ports. Barbed ports provide mechanical retention through tubing deformation, while barbless ports require external tubing clamps or compression fittings. Tubing compatibility depends on inner diameter specifications and connection method; consult tubing supplier documentation for specific applications.

Q: What is the impact of package size differences (6-SIP versus 4-SIP)?

A: The DCXL30DS and 30 INCH-D-MV use 6-SIP modules, while TSCSNBN001PDUCV and SSCSNBN030NDAA5 use 4-SIP modules. SIP (Single In-line Package) designations indicate the number of pins and physical footprint dimensions. Substituting between different SIP sizes requires PCB redesign to accommodate new pin spacing and component placement. Direct socket compatibility is not possible between 6-SIP and 4-SIP configurations.

Q: Which substitute part offers the best long-term availability?

A: All three substitute parts are classified as active products with current manufacturing status. The TSCSNBN001PDUCV and SSCSNBN030NDAA5 are part of Honeywell's TruStability series, which represents current-generation sensor technology with established supply chains. The 30 INCH-D-MV from Amphenol All Sensors Corporation is also actively produced. For long-term procurement planning, consult directly with manufacturers regarding production roadmaps and end-of-life timelines.

Q: How do operating temperature ranges affect sensor selection?

A: The DCXL30DS operates from -25°C to 85°C. The TSCSNBN001PDUCV and SSCSNBN030NDAA5 extend the lower temperature limit to -40°C, providing enhanced performance in cold environments. The 30 INCH-D-MV maintains the -25°C to 85°C range, matching the original specification. Temperature compensation is implemented in all four sensors to maintain accuracy across the operating range. Application-specific temperature requirements should drive selection when operating conditions approach temperature extremes.
