SCC15AD2 Equivalent & Substitute Parts Reference

Part Overview

The SCC15AD2 is a pressure sensor manufactured by Honeywell Sensing and Productivity Solutions, designed for absolute pressure measurement applications requiring board mount integration. This 6-DIP module sensor measures 15 PSI (103.42 kPa) with a Wheatstone Bridge output configuration and operates across the -40°C to 85°C temperature range. The product is classified as obsolete, making equivalent and substitute part identification essential for ongoing system support, maintenance, and new design implementations where this sensor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCC15AD2 pressure sensor is determined by strict alignment of the following critical parameters:

Pressure Measurement Specification: Both the main part and substitute must measure absolute pressure at 15 PSI (103.42 kPa) operating range with maximum pressure rating of 30 PSI (206.84 kPa).

Output Configuration: The Wheatstone Bridge output type must be maintained to ensure signal conditioning compatibility with existing circuit designs.

Temperature Operating Range: The -40°C to 85°C operating temperature envelope must be preserved for thermal environment compatibility.

Mounting and Termination: Through-hole mounting with PC pin termination is required for direct PCB integration without redesign.

Compliance Standards: RoHS compliance and MSL rating of 1 (Unlimited) must be maintained for regulatory and manufacturing process compatibility.

The NSCDANN015PAUNV substitute part meets these core substitution criteria while operating within the allowed parameter variations for this sensor category. Variations in port size (0.19" versus 0.11" tube), package configuration (8-DIP versus 6-DIP), output voltage range (0-75 mV at 5V versus 40-95 mV), and accuracy specification (±0.25% versus ±0.5%) represent acceptable engineering trade-offs within the pressure sensor product category when the primary functional requirements are maintained.

Parameter Comparison

Engineering Selection Recommendations

Obsolescence Status: Both the SCC15AD2 and NSCDANN015PAUNV are classified as obsolete products. Selection between these parts should be based on current inventory availability and application-specific requirements rather than product lifecycle considerations.

Regulatory Compliance: Both parts maintain RoHS compliance and MSL rating 1 (Unlimited), satisfying regulatory requirements for manufacturing and deployment in compliant supply chains.

Functional Equivalence: The NSCDANN015PAUNV substitute maintains the core functional specification of 15 PSI absolute pressure measurement with Wheatstone Bridge output across the identical -40°C to 85°C operating temperature range. The substitute is suitable for applications where the SCC15AD2 is no longer available.

Physical Integration Considerations: The substitute part features an 8-DIP package versus the 6-DIP configuration of the main part, and includes a top port orientation. PCB layout modifications may be required to accommodate the different package footprint and port location. The port size difference (0.19" versus 0.11" tube) necessitates tubing adapter evaluation for pneumatic connections.

Signal Conditioning: The output voltage range differs between parts (40-95 mV for SCC15AD2 versus 0-75 mV for NSCDANN015PAUNV at 5V supply). Existing signal conditioning circuits must be evaluated for compatibility with the substitute part's output characteristics and supply voltage requirements (1.5V-12V for substitute versus unspecified for main part).

Accuracy Trade-off: The NSCDANN015PAUNV provides improved accuracy (±0.25%) compared to the SCC15AD2 (±0.5%), representing a performance enhancement for applications requiring tighter measurement tolerance.

Frequently Asked Questions (FAQ)

Q: Can the NSCDANN015PAUNV directly replace the SCC15AD2 without PCB modifications?

A: Direct replacement without PCB modifications is not possible. The NSCDANN015PAUNV uses an 8-DIP package with top port configuration, while the SCC15AD2 uses a 6-DIP module. PCB layout changes are required to accommodate the different package footprint and pin configuration.

Q: What are the pneumatic connection implications of the different port sizes?

A: The SCC15AD2 features a 0.11" (2.67 mm) male barbless tube port, while the NSCDANN015PAUNV features a 0.19" (4.93 mm) male barbed tube port. Tubing adapters or new tubing assemblies are required to connect the substitute part to existing pneumatic systems designed for the smaller barbless port.

Q: Are the output signals compatible between these two sensors?

A: Both sensors use Wheatstone Bridge output configuration, but the output voltage ranges differ. The SCC15AD2 outputs 40-95 mV, while the NSCDANN015PAUNV outputs 0-75 mV at 5V supply. Signal conditioning circuits must be re-evaluated and potentially recalibrated to accommodate the different output range and supply voltage requirements (1.5V-12V for the substitute).

Q: What is the significance of the accuracy difference between these parts?

A: The NSCDANN015PAUNV provides ±0.25% accuracy compared to the SCC15AD2's ±0.5% accuracy. This represents a tighter measurement tolerance and may be beneficial for applications requiring higher precision, though it does not affect basic substitution compatibility.

Q: Are both parts suitable for the same temperature operating environments?

A: Yes. Both the SCC15AD2 and NSCDANN015PAUNV operate across the identical -40°C to 85°C temperature range, ensuring thermal environment compatibility.

Q: What inventory considerations should guide part selection?

A: Both parts are classified as obsolete. Selection should prioritize current inventory availability from authorized distributors. The SCC15AD2 has 1068 pieces in stock, while the NSCDANN015PAUNV has 721 pieces available. Availability may vary by distributor and region.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the SCC15AD2 and NSCDANN015PAUNV are RoHS compliant with MSL rating 1 (Unlimited), satisfying identical regulatory and manufacturing process requirements.
