SCC15DN Pressure Sensor: Equivalent & Substitute Parts

Part Overview

The SCC15DN is a differential pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for board mount applications requiring 15PSI (103.42kPa) differential pressure measurement. This component features a Wheatstone Bridge output with 40 mV ~ 95 mV signal range and operates across -40°C to 85°C. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC15DN is determined by the following critical parameters that must align between the original and substitute component:

Pressure Measurement Compatibility:

• Differential pressure type (not gauge or absolute)
• Operating pressure range of ±15PSI (±103.42kPa)
• Maximum pressure rating of ±30PSI (±206.84kPa)

Electrical Interface Compatibility:

• Wheatstone Bridge output configuration
• Through-hole mounting with PC pin termination
• 4-SIP module package format

Environmental Compliance:

• Operating temperature range -40°C to 85°C
• RoHS compliance certification

Mechanical Interface Compatibility:

• Dual barbed male tube ports
• Port size and configuration for fluid connection

The NSCSHHN015PDUNV qualifies as a direct substitute based on matching pressure type, differential measurement capability, Wheatstone Bridge output, 4-SIP package configuration, through-hole mounting, PC pin termination, operating temperature range, and RoHS compliance status.

Engineering Selection Recommendations

The NSCSHHN015PDUNV is the designated substitute for the obsolete SCC15DN based on functional equivalence in pressure measurement, output configuration, and package format. Key considerations for selection:

Product Status Advantage: The NSCSHHN015PDUNV maintains active product status with Honeywell, ensuring continued availability, technical support, and supply chain reliability compared to the obsolete SCC15DN.

Compliance Certification: Both components maintain RoHS compliance, satisfying regulatory requirements for electronic component procurement in regulated industries.

Output Signal Differences: The substitute provides 0 mV ~ 155 mV output versus the original 40 mV ~ 95 mV range. Signal conditioning or calibration adjustment may be required in existing circuit designs to accommodate this difference.

Accuracy Improvement: The NSCSHHN015PDUNV offers ±0.25% accuracy compared to the original ±0.5%, representing enhanced measurement precision.

Port Size Variation: The substitute features 0.16" (3.94mm) ports versus the original 0.19" (4.8mm) ports. Tubing and connector compatibility must be verified for the specific application.

Supply Voltage Specification: The substitute requires 1.5V ~ 12V supply voltage, which must be confirmed as compatible with existing power delivery systems.

Frequently Asked Questions (FAQ)

Q: Can the NSCSHHN015PDUNV directly replace the SCC15DN without circuit modifications?

A: Both components share Wheatstone Bridge output configuration, 4-SIP package format, and through-hole PC pin termination. However, the output signal range differs (0 mV ~ 155 mV versus 40 mV ~ 95 mV), requiring signal conditioning circuit adjustment or calibration offset in the measurement electronics.

Q: What is the significance of the port size difference between these components?

A: The SCC15DN features 0.19" (4.8mm) barbed male ports, while the NSCSHHN015PDUNV uses 0.16" (3.94mm) barbed male ports. Existing tubing connections and fittings must be verified for compatibility with the smaller port diameter of the substitute component.

Q: Are both components suitable for the same temperature operating range?

A: Yes. Both the SCC15DN and NSCSHHN015PDUNV operate across -40°C to 85°C, ensuring thermal compatibility for applications within this range.

Q: What does "Same Side" port configuration mean for the NSCSHHN015PDUNV?

A: The "Same Side" designation indicates that both dual ports are positioned on the same side of the 4-SIP module package, affecting the physical layout and tubing routing compared to the original SCC15DN configuration.

Q: Is the improved accuracy of the substitute component a direct benefit?

A: The NSCSHHN015PDUNV provides ±0.25% accuracy versus the original ±0.5%. This represents enhanced measurement precision; however, the system benefit depends on whether the application requires this improved accuracy specification.

Q: What supply voltage must be provided to the NSCSHHN015PDUNV?

A: The substitute requires 1.5V ~ 12V supply voltage. The original SCC15DN supply voltage specification was not provided in the component data. Verify that the existing power supply circuit can deliver voltage within the 1.5V ~ 12V range.

Q: Are both components RoHS compliant?

A: Yes. Both the SCC15DN and NSCSHHN015PDUNV are RoHS compliant, meeting regulatory requirements for hazardous substance restrictions in electronic components.
