• Flat-top emitting surface for light pipe integration
• Wide 120-degree viewing angle
• High-reliability construction for architectural environments

Applications

• Channel letter illumination
• Architectural lighting
• Light strip integration

Procurement Notes

Verify the specific suffix 'CWAXB693' against official Cree LED documentation to confirm exact binning parameters, luminous intensity ranges, and forward voltage specifications. Ensure the ordering part number matches the required color and intensity grades for the target application. Cross-reference datasheet revision dates to confirm current manufacturing status and compliance certifications.

Selection Notes

Select this component for designs requiring a standard PLCC-4 footprint with high reliability. The flat-top lens profile facilitates precise optical coupling with light guides or diffusers. Confirm that the thermal management design supports the device's operating temperature range and that the drive current aligns with the specified absolute maximum ratings found in the official electrical characteristics table.

Part Context

This component belongs to the Cree LED PLCC4 1-in-1 SMD LED series, which provides high-reliability performance for architectural and signage applications. The family utilizes a standardized package size to simplify PCB layout and supply chain management while offering various color and intensity options through specific ordering suffixes.

Replacement Considerations

Direct substitutes within the same PLCC-4 form factor include other Cree LED variants such as CLM4B-BKW or CLM4B-AKW, provided the wavelength and intensity requirements are met. Verify pinout compatibility and thermal characteristics before substitution.
