SCC15A Pressure Sensor Equivalent & Substitute Parts

Part Overview

The SCC15A is a 15 PSI absolute pressure sensor manufactured by Honeywell Sensing and Productivity Solutions. This component is a board-mount pressure transducer housed in a 4-SIP module package with PC pin termination, designed for applications requiring absolute pressure measurement with temperature compensation. The SCC15A operates across a temperature range of -40°C to 85°C and delivers a Wheatstone Bridge output of 40 mV to 95 mV.

The SCC15A has reached obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems currently utilizing this sensor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCC15A is determined by strict alignment of the following critical parameters:

Pressure Specification: The substitute part must measure absolute pressure at 15 PSI (103.42 kPa) with a maximum pressure rating of 30 PSI (206.84 kPa).

Output Configuration: The substitute must employ a Wheatstone Bridge output topology to maintain signal conditioning compatibility with existing circuit designs.

Package and Termination: The substitute must be housed in a 4-SIP module with PC pin termination to ensure mechanical and electrical compatibility with through-hole PCB mounting.

Operating Environment: The substitute must support the full operating temperature range of -40°C to 85°C.

Regulatory Compliance: The substitute must maintain RoHS compliance and equivalent ECCN/HTSUS classifications.

The NSCSSNN015PAUNV meets all these criteria and qualifies as a direct substitute for the SCC15A.

Parameter Comparison

Engineering Selection Recommendations

The NSCSSNN015PAUNV is the qualified substitute for the obsolete SCC15A based on the following engineering criteria:

Product Status and Supply Continuity: The SCC15A is obsolete with no ongoing manufacturing. The NSCSSNN015PAUNV is an active product with current production and documented inventory availability, ensuring long-term supply chain reliability.

Regulatory and Compliance Alignment: Both components maintain RoHS compliance and share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory equivalence for export and procurement purposes.

Functional Compatibility: Both sensors employ identical pressure measurement specifications (15 PSI absolute, 30 PSI maximum), Wheatstone Bridge output topology, 4-SIP module packaging, and PC pin termination. This ensures direct mechanical and electrical compatibility with existing PCB designs and signal conditioning circuits.

Performance Enhancement: The NSCSSNN015PAUNV delivers improved accuracy (±0.25% versus ±0.5%) and specifies a supply voltage range (1.5V ~ 12V), providing greater design flexibility and measurement precision compared to the original SCC15A.

Output Voltage Consideration: The output voltage range differs between the two sensors (40 mV ~ 95 mV for SCC15A versus 0 mV ~ 75 mV for NSCSSNN015PAUNV). Circuit designs must accommodate this output range variation through appropriate signal conditioning or amplification adjustments.

Frequently Asked Questions (FAQ)

Q: Can the NSCSSNN015PAUNV be used as a direct drop-in replacement for the SCC15A?

A: The NSCSSNN015PAUNV is mechanically and electrically compatible with the SCC15A in terms of package type (4-SIP), termination style (PC pin), mounting method (through hole), and pressure measurement specification (15 PSI absolute). However, the output voltage range differs. The SCC15A outputs 40 mV ~ 95 mV, while the NSCSSNN015PAUNV outputs 0 mV ~ 75 mV. Signal conditioning circuits must be evaluated and adjusted to accommodate this output range variation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: (1) identical absolute pressure rating (15 PSI / 103.42 kPa), (2) identical maximum pressure rating (30 PSI / 206.84 kPa), (3) identical output topology (Wheatstone Bridge), (4) identical package type (4-SIP module), (5) identical termination style (PC pin), (6) identical mounting type (through hole), (7) compatible operating temperature range (-40°C ~ 85°C), and (8) equivalent regulatory compliance (RoHS, ECCN, HTSUS).

Q: Are there any supply voltage considerations when substituting the NSCSSNN015PAUNV?

A: The NSCSSNN015PAUNV specifies a supply voltage range of 1.5V ~ 12V. The original SCC15A does not specify a supply voltage range in the provided documentation. Designs must ensure that the power supply used for the NSCSSNN015PAUNV falls within the 1.5V ~ 12V range to ensure proper sensor operation.

Q: How does the accuracy difference affect system performance?

A: The NSCSSNN015PAUNV provides ±0.25% accuracy compared to the SCC15A's ±0.5% accuracy. This represents a 50% improvement in measurement precision. Existing system designs do not require modification to accommodate this improvement; however, applications requiring tighter accuracy specifications will benefit from the enhanced performance of the substitute part.

Q: Are both components RoHS compliant?

A: Yes, both the SCC15A and NSCSSNN015PAUNV are RoHS compliant and share identical ECCN (EAR99) and HTSUS (9026.20.4000) classifications, ensuring regulatory equivalence for procurement and export purposes.

Q: What is the moisture sensitivity level for both sensors?

A: Both the SCC15A and NSCSSNN015PAUNV have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
