SCXL010DN Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCXL010DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications with a 0.36 PSI (2.49 kPa) measurement range. This component features a Wheatstone Bridge output configuration with 0 mV to 20 mV signal range at 12V supply voltage, barbed male tube ports (0.19" / 4.8mm dual), and through-hole PC pin termination in a 4-SIP module package.

The SCXL010DN is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system functionality, ensure continued component availability, and support legacy equipment maintenance and redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCXL010DN requires evaluation of the following critical parameters that define functional equivalence:

Pressure Measurement Capability: The substitute must support the same 0.36 PSI (2.49 kPa) operating pressure range. Both differential and vented gauge pressure types can serve applications requiring low-pressure measurement at this scale, provided the pressure type change is compatible with the system design.

Physical Interface: Port size, style, and configuration must accommodate existing tubing and manifold connections. The SCXL010DN uses dual male barbed ports at 0.19" (4.8mm). Substitutes with equivalent port geometry ensure direct mechanical compatibility.

Electrical Interface: Package type (4-SIP), termination style (PC pin through-hole), and mounting type (board mount) must match to enable direct PCB socket or connector compatibility without redesign.

Environmental Compliance: RoHS compliance and operating temperature range (-40°C ~ 85°C) ensure regulatory and thermal compatibility with existing systems.

Output Signal Characteristics: While the SCXL010DN outputs 0 mV ~ 20 mV via Wheatstone Bridge, substitutes with different output types (such as amplified analog voltage) may be acceptable if signal conditioning or interface electronics can accommodate the new output range and impedance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Feasibility: The SSCSNBN010NGAA5 shares the same pressure measurement range (0.36 PSI), port size (0.19" male dual), package family (4-SIP), termination style (PC pin), and operating temperature range (-40°C ~ 85°C) as the SCXL010DN. However, direct socket-level substitution is not possible without system modifications.

Required System Changes: Implementation of the SSCSNBN010NGAA5 as a substitute requires the following modifications:

1. Power Supply Redesign: The SCXL010DN operates at 20V supply, while the SSCSNBN010NGAA5 requires 4.95V ~ 5.05V. Power distribution circuitry must be redesigned to accommodate the lower voltage requirement.

2. Signal Conditioning: The SCXL010DN outputs 0 mV ~ 20 mV via Wheatstone Bridge (high impedance, low level signal). The SSCSNBN010NGAA5 outputs 0.5 V ~ 4.5 V (amplified analog voltage, lower impedance). Signal processing and analog-to-digital conversion circuits must be reconfigured to accept the higher voltage range and different impedance characteristics.

3. Pressure Type Consideration: The SCXL010DN measures differential pressure, while the SSCSNBN010NGAA5 measures vented gauge pressure. Differential pressure applications require both high and low pressure ports to be connected to separate pressure sources. Vented gauge pressure applications require one port connected to the measured pressure source and the other port vented to atmosphere. System design must confirm that vented gauge measurement is functionally equivalent to the original differential measurement requirement.

4. Tubing Interface: The SCXL010DN uses barbed ports, while the SSCSNBN010NGAA5 uses barbless ports. Tubing connection methods and fittings must be updated accordingly.

Compliance and Availability: Both components are RoHS compliant. The SSCSNBN010NGAA5 is currently in active production with 1420 units in stock, ensuring long-term availability compared to the obsolete SCXL010DN status. The substitute offers improved accuracy (±0.25% versus ±1%) and higher overpressure rating (10.84 PSI versus 10 PSI).

Frequently Asked Questions (FAQ)

Q: Can the SSCSNBN010NGAA5 be used as a direct drop-in replacement for the SCXL010DN?

A: No. While both sensors share the same pressure range, port size, package family, and operating temperature, they differ in output type, supply voltage, pressure measurement type, and port style. Direct substitution without circuit modifications is not possible.

Q: What is the primary difference between differential and vented gauge pressure measurement?

A: Differential pressure sensors measure the pressure difference between two independent pressure sources connected to separate ports. Vented gauge pressure sensors measure pressure relative to atmospheric pressure, with one port connected to the measured pressure source and the other port vented to atmosphere. System design must confirm that vented gauge measurement satisfies the original application requirement.

Q: Why does the SSCSNBN010NGAA5 require a different power supply voltage?

A: The SCXL010DN uses a Wheatstone Bridge output configuration that operates at 20V excitation voltage. The SSCSNBN010NGAA5 uses an amplified analog voltage output that operates at 5V supply voltage. This represents a fundamental difference in sensor architecture and signal conditioning approach.

Q: Are the port connections compatible between these two sensors?

A: The port size (0.19" / 4.8mm male dual) is identical, but the port style differs. The SCXL010DN uses barbed ports designed for push-fit tubing connections. The SSCSNBN010NGAA5 uses barbless ports that require different tubing fittings or connectors. Tubing interface components must be updated.

Q: What signal processing changes are required to use the SSCSNBN010NGAA5?

A: The SCXL010DN outputs 0 mV ~ 20 mV (low level, high impedance Wheatstone Bridge signal). The SSCSNBN010NGAA5 outputs 0.5 V ~ 4.5 V (amplified analog voltage, lower impedance). Analog-to-digital conversion circuits, signal conditioning amplifiers, and software calibration constants must be reconfigured to accommodate the new voltage range and impedance characteristics.

Q: Is the SSCSNBN010NGAA5 available for purchase?

A: Yes. The SSCSNBN010NGAA5 is classified as active product status with 1420 units currently in stock, ensuring availability for new designs and legacy system maintenance.

Q: Do both sensors meet RoHS compliance requirements?

A: Yes. Both the SCXL010DN and SSCSNBN010NGAA5 are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the accuracy difference between these sensors?

A: The SCXL010DN specifies ±1% accuracy, while the SSCSNBN010NGAA5 specifies ±0.25% accuracy. The substitute offers improved measurement precision.
