CLA2A-WKW-CYAZ0343

Overview

The CLA2A-WKW-CYAZ0343 is a surface-mount LED from Cree LED, packaged in a standard PLCC4 case. It emits cool white light with a color temperature of 5500 K and a typical forward voltage of 3.2 V at a test current of 20 mA. The component features a circular diffused lens with a 120-degree viewing angle. Luminous intensity is rated at 4200 mcd (or 3.8 cd), providing reliable illumination for discrete indication tasks.

Feature Summary

• Surface mount construction in industry-standard PLCC4 package
• Cool white emission with 5500K color temperature
• Wide 120-degree viewing angle for broad visibility
• Diffused lens design for uniform light distribution

Applications

• General lighting applications
• Specialty lighting applications
• System level performance integration

Procurement Notes

Verify the specific ordering suffix to ensure the correct binning for luminous intensity and color temperature matches your design requirements. Confirm the PLCC4 package dimensions align with your PCB footprint. Check the operating temperature range specifications against your environmental conditions to ensure reliability under expected thermal loads.

Selection Notes

Select this component when a standard SMD form factor is required for cool white indication. The PLCC4 package offers compatibility with common automated assembly processes. Consider the 120-degree viewing angle if wide-area visibility is necessary. Ensure the 3.2V forward voltage drop fits within your circuit's power budget and current limiting resistor calculations.

Part Context

This part belongs to the Cree LED CLA2A series, which utilizes the PLCC4 package format. This series is designed to simplify designs and lower system costs while delivering consistent performance. The CLA2A line supports various color options and intensities, making it suitable for diverse electronic indication needs across consumer and industrial devices.

Replacement Considerations

Direct substitutes must match the PLCC4 package, 5500K color temperature, and similar luminous intensity. Verify pinout compatibility and forward voltage characteristics before substitution. Cross-reference datasheets for thermal resistance and maximum current ratings to ensure equivalent operational safety and longevity in the target application.
