SCX100DNC Equivalent & Substitute Parts Reference

Part Overview

The SCX100DNC is an active differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component operates within the SCX series and delivers a 0 mV to 100 mV output signal at 12V supply, designed for board mount applications requiring precise pressure measurement up to 100 PSI (689.48 kPa). The sensor features temperature compensation and Wheatstone Bridge output configuration with PC pin termination in a 6-SIP module package.

Finding equivalent and substitute parts becomes necessary when the SCX100DNC reaches end-of-life status, inventory constraints occur, or alternative sourcing is required for supply chain optimization. The substitute parts listed below maintain functional compatibility based on critical electrical and mechanical parameters while offering different performance characteristics or packaging options.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCX100DNC are classified based on strict adherence to the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Pressure Type: Differential
• Operating Pressure: 100 PSI (689.48 kPa)
• Port Size: Male - 0.19" (4.8mm) Tube, Dual
• Port Style: Barbed
• Package / Case: 6-SIP Module
• Termination Style: PC Pin
• Mounting Type: Through Hole
• Features: Temperature Compensated

Parametric Equivalent Classification: The SCX100DN maintains identical specifications to the SCX100DNC across all critical parameters. The primary distinction is packaging format (Bulk versus standard packaging) and improved accuracy specification (±1% versus ±5%). This part is a direct parametric equivalent suitable for applications where the SCX100DNC is specified.

Similar Manufacturer Classification: The PHPSU-4502-100P-D from Angst+Pfister Sensors and Power AG shares the same pressure rating, port configuration, and 6-SIP module package. However, this part exhibits variations in output range (0 mV ~ 90 mV versus 0 mV ~ 100 mV), supply voltage flexibility (12V ~ 20V versus fixed 20V), maximum pressure rating (200 PSI versus 150 PSI), and operating temperature range (-25°C ~ 85°C versus -40°C ~ 85°C). These differences require circuit-level evaluation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

SCX100DN Selection Criteria: The SCX100DN is the primary substitute for the SCX100DNC. Both parts maintain Active product status and RoHS compliance. The SCX100DN offers superior accuracy (±1% versus ±5%) while maintaining identical electrical and mechanical specifications. Selection of SCX100DN is appropriate when inventory availability of the SCX100DNC is constrained and improved measurement accuracy is acceptable within the application circuit design.

PHPSU-4502-100P-D Selection Criteria: The PHPSU-4502-100P-D from Angst+Pfister Sensors and Power AG is classified as a similar manufacturer part requiring circuit-level compatibility assessment. This part is suitable only when the following conditions are met: (1) the application circuit can accommodate the reduced output range of 0 mV ~ 90 mV instead of 0 mV ~ 100 mV, (2) the operating temperature range minimum of -25°C (versus -40°C) is acceptable for the intended application, and (3) the supply voltage flexibility of 12V ~ 20V aligns with system design. The higher maximum pressure rating (200 PSI) and superior accuracy (±0.5%) may provide additional design margin in pressure-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can SCX100DN be used as a direct replacement for SCX100DNC in existing designs?

A: Yes. The SCX100DN maintains identical pressure rating, port configuration, output type, package format, and termination style. The primary difference is improved accuracy specification (±1% versus ±5%). No circuit modifications are required for substitution.

Q: What are the key differences between SCX100DNC and PHPSU-4502-100P-D?

A: The PHPSU-4502-100P-D differs in three critical areas: (1) output range is 0 mV ~ 90 mV instead of 0 mV ~ 100 mV, requiring signal conditioning circuit adjustment; (2) operating temperature minimum is -25°C instead of -40°C; (3) supply voltage accepts 12V ~ 20V range instead of fixed 20V. These differences require circuit evaluation before substitution.

Q: Is the PHPSU-4502-100P-D suitable for applications requiring -40°C operation?

A: No. The PHPSU-4502-100P-D operating temperature range is -25°C ~ 85°C. Applications requiring -40°C minimum operating temperature must use SCX100DNC or SCX100DN.

Q: What is the significance of the output range difference between SCX100DNC (0-100 mV) and PHPSU-4502-100P-D (0-90 mV)?

A: The output range difference affects signal conditioning and analog-to-digital conversion scaling. Circuits designed for 0-100 mV output will require recalibration or signal conditioning modification to accommodate the 0-90 mV output of the PHPSU-4502-100P-D.

Q: Are all three parts RoHS compliant?

A: SCX100DNC and SCX100DN are confirmed RoHS Compliant. RoHS compliance status for PHPSU-4502-100P-D is not specified in available documentation.

Q: What packaging options are available for these pressure sensors?

A: SCX100DNC is supplied in standard packaging. SCX100DN is supplied in Bulk packaging. Both maintain identical 6-SIP module case format and PC pin termination. Packaging selection depends on procurement quantity requirements and inventory management practices.

Q: Can these sensors be used interchangeably in high-pressure applications?

A: Maximum pressure ratings differ: SCX100DNC and SCX100DN are rated to 150 PSI, while PHPSU-4502-100P-D is rated to 200 PSI. For applications approaching or exceeding 150 PSI, the PHPSU-4502-100P-D provides additional pressure margin. However, other parameter differences must still be evaluated.
