SCC15AN Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC15AN is a 15 PSI absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component features a Wheatstone Bridge output with a 40 mV to 95 mV signal range, designed for board mount applications with through-hole termination in a 4-SIP module package. The product is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and new design implementations. The sensor operates across a temperature range of -40°C to 85°C with ±0.5% accuracy and is RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCC15AN is determined by the following critical parameters:

Pressure Specification Match: The substitute must maintain the same 15 PSI (103.42 kPa) absolute pressure rating and 30 PSI maximum pressure specification to ensure functional equivalence in the target application.

Output Type Compatibility: Both the main part and substitute must utilize Wheatstone Bridge output configuration to maintain signal conditioning compatibility with existing circuit designs.

Operating Temperature Range: The substitute must support the full -40°C to 85°C operating temperature envelope to ensure reliability across all specified environmental conditions.

Package and Termination: Through-hole mounting with PC pin termination in a 4-SIP module configuration is required for direct board-level compatibility.

Port Configuration: While port size may vary within acceptable mechanical tolerances, the barbed male tube connection style and dual-port configuration must be maintained for pneumatic interface compatibility.

Compliance Standards: RoHS compliance status must be maintained to satisfy regulatory and procurement requirements.

The NSCSHHN015PAUNV meets these substitution criteria while introducing improved specifications in output accuracy and supply voltage flexibility.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The SCC15AN is classified as obsolete. The NSCSHHN015PAUNV from the TruStability® NSC series represents the current generation equivalent from Honeywell Sensing and Productivity Solutions, offering improved accuracy (±0.25% versus ±0.5%) while maintaining core functional parameters.

Output Signal Consideration: The substitute part produces a 0 mV to 75 mV output range compared to the original 40 mV to 95 mV range. Circuit designs utilizing the original sensor output must be evaluated to determine if signal conditioning adjustments are required. The substitute's specified supply voltage range of 1.5V to 12V provides greater flexibility than the unspecified original part.

Mechanical Interface: The port size reduction from 0.19" (4.8mm) to 0.16" (3.94mm) requires verification of pneumatic connection compatibility. Adapter fittings may be necessary depending on existing tubing specifications.

Regulatory Compliance: Both components maintain RoHS compliance status, satisfying environmental and procurement standards. Moisture sensitivity level remains at MSL 1 (Unlimited) for both parts.

Product Status: The NSCSHHN015PAUNV is listed as discontinued at DiGi Electronics but represents the active Honeywell product line. Availability should be confirmed through current distribution channels prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the NSCSHHN015PAUNV be used as a direct drop-in replacement for the SCC15AN?

A: The NSCSHHN015PAUNV is functionally equivalent for pressure measurement applications at 15 PSI absolute. However, two factors require evaluation: the output signal range differs (0-75 mV versus 40-95 mV), and the port size is smaller (0.16" versus 0.19"). Circuit signal conditioning and pneumatic connections must be assessed for compatibility.

Q: What are the key differences in electrical output between these two sensors?

A: The SCC15AN produces 40 mV to 95 mV output, while the NSCSHHN015PAUNV produces 0 mV to 75 mV output at 5V supply. Both utilize Wheatstone Bridge configuration. The substitute offers improved accuracy at ±0.25% compared to ±0.5% for the original part.

Q: Are there supply voltage differences I need to consider?

A: The SCC15AN supply voltage is not specified in the available documentation. The NSCSHHN015PAUNV requires 1.5V to 12V supply. Existing power supply designs should be verified to ensure they fall within this range.

Q: What is the significance of the port size difference?

A: The SCC15AN uses 0.19" (4.8mm) barbed male tube connections, while the NSCSHHN015PAUNV uses 0.16" (3.94mm). Existing pneumatic tubing and fittings must be compatible with the smaller port size, or adapter fittings must be employed.

Q: Do both sensors have the same temperature operating range?

A: Yes, both the SCC15AN and NSCSHHN015PAUNV operate across -40°C to 85°C, ensuring equivalent thermal performance across all specified environmental conditions.

Q: Are there any compliance or certification differences?

A: Both components are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity level. ECCN and HTSUS classifications are identical, indicating equivalent regulatory treatment.

Q: What should I verify before implementing the NSCSHHN015PAUNV as a replacement?

A: Verify circuit compatibility with the different output signal range, confirm pneumatic connection compatibility with the smaller port size, validate supply voltage availability within the 1.5V to 12V specification, and confirm current availability through active distribution channels.
