SCXL004DN Equivalent & Substitute Parts Reference

Part Overview

The SCXL004DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring low-pressure measurement. This sensor operates with a Wheatstone Bridge output configuration and delivers 0 mV to 40 mV output at 12V supply voltage. The product is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating.

Equivalent and substitute parts are identified when alternative sensors meet the core functional requirements while maintaining compatibility with the host system's electrical and mechanical interfaces. Substitution becomes necessary due to component availability, supply chain considerations, or specific application performance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCXL004DN is determined by the following critical parameters:

Mechanical Compatibility Requirements:

• Package type must be 6-SIP Module
• Termination style must be PC Pin for Through Hole mounting
• Port configuration must accommodate Male barbed or barbless 0.19" tube connections
• Board mount application compatibility

Electrical Compatibility Requirements:

• Output type must be Wheatstone Bridge configuration
• Supply voltage must be compatible with 18V maximum rating
• Output signal must be within acceptable range for 12V operation
• Differential pressure measurement capability

Performance Criteria:

• Operating pressure range must encompass or be compatible with 0.15 PSI (1 kPa) nominal measurement
• Temperature compensation feature required
• Operating temperature range must support minimum 0°C to 70°C operation

Compliance Requirements:

• RoHS compliance status (RoHS Compliant or ROHS3 Compliant acceptable)
• Active product status preferred for long-term availability

The 1 INCH-D-MV from Amphenol All Sensors Corporation meets these substitution criteria with documented compatibility across mechanical, electrical, and compliance parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The SCXL004DN remains the specified component when the application requires the exact 0.15 PSI nominal operating pressure with 0 mV to 40 mV output scaling. This sensor is actively produced and maintains full RoHS compliance with unlimited moisture sensitivity rating.

Substitution with 1 INCH-D-MV:

The 1 INCH-D-MV from Amphenol All Sensors Corporation is electrically and mechanically compatible as a substitute when the following conditions are met:

1. The application can accommodate a lower nominal pressure range (0.04 PSI vs. 0.15 PSI)
2. Signal output scaling difference (0-10 mV vs. 0-40 mV) is acceptable or can be addressed through signal conditioning
3. The barbed vs. barbless port configuration is compatible with the tubing interface
4. Extended temperature operation (-25°C to 85°C) is beneficial or required
5. Superior accuracy (±0.25% vs. ±1%) meets or exceeds application requirements

Both components share identical package type (6-SIP Module), termination style (PC Pin Through Hole), output type (Wheatstone Bridge), and temperature compensation features. Both maintain current compliance certifications (RoHS Compliant and ROHS3 Compliant respectively).

Compliance Status:

Both parts are active products with appropriate RoHS compliance. The substitute part meets ROHS3 standard, representing current regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1 INCH-D-MV directly replace the SCXL004DN without circuit modifications?

A: Mechanical and electrical interfaces are compatible. However, the output signal range differs (0-10 mV vs. 0-40 mV at 12V). Direct substitution without signal conditioning is possible only if the receiving circuit can accommodate the lower output voltage range. Verify that the analog-to-digital converter or signal processing circuit has sufficient sensitivity for 10 mV full-scale output.

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

A: The SCXL004DN features barbed ports (0.19" / 4.8mm) while the 1 INCH-D-MV has barbless ports (0.19" / 4.83mm). Barbed connections provide mechanical retention through tubing deformation, while barbless connections rely on friction fit. Tubing compatibility must be verified for the specific application. Port diameter is nominally equivalent (0.03mm difference is within manufacturing tolerance).

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

A: The sensors are suitable for different pressure ranges. The SCXL004DN is specified for 0.15 PSI (1 kPa) nominal operation with 0.36 PSI maximum. The 1 INCH-D-MV operates at 0.04 PSI (0.25 kPa) nominal with 3.61 PSI maximum. Application selection depends on the actual pressure range being measured. The substitute part is better suited for ultra-low pressure applications below 0.15 PSI.

Q: What are the temperature operating differences?

A: The SCXL004DN operates from 0°C to 70°C. The 1 INCH-D-MV extends this range to -25°C to 85°C. Both sensors include temperature compensation. If the application requires operation below 0°C or above 70°C, the substitute part provides extended capability.

Q: How do the accuracy specifications compare?

A: The SCXL004DN provides ±1% accuracy. The 1 INCH-D-MV offers ±0.25% accuracy, representing a fourfold improvement in measurement precision. Applications requiring higher accuracy benefit from the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. The SCXL004DN is RoHS Compliant. The 1 INCH-D-MV is ROHS3 Compliant, representing the current regulatory standard. Both parts meet environmental compliance requirements for electronic component manufacturing and use.

Q: What is the supply voltage compatibility?

A: The SCXL004DN is rated for 18V supply. The 1 INCH-D-MV operates at 16V. The substitute part can be powered from an 18V supply without exceeding its rating. Both sensors are designed for 12V operation in the specified output configurations.

Q: Can I use the 1 INCH-D-MV in a system designed for the SCXL004DN?

A: Mechanical compatibility is confirmed (6-SIP Module package, PC Pin termination, Through Hole mounting). Electrical compatibility requires verification of signal conditioning circuits to accommodate the different output voltage range. Pressure range compatibility depends on the actual measurement requirements of the application. Consult system documentation to confirm all three compatibility factors before substitution.
