• Ensures extremely stable light output over long periods for dependable performance.
• Delivers superior light output for excellent readability in direct sunlight.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)
• Advertising Signs

Procurement Notes

Verify the specific suffix CY0C0462 against official Cree documentation to confirm binning and packaging details. Ensure compatibility with existing thermal management designs given the 120 mW power rating. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high-brightness blue illumination with a narrow 15-degree beam angle. The 5 mm through-hole form factor suits legacy or robust mechanical assemblies. Consider the 3.2 V forward voltage drop when designing series resistor networks or constant current drivers for optimal efficiency.

Part Context

This part belongs to the C503B round LED family, which includes various color options like green and amber. These LEDs are engineered for outdoor durability and visual clarity. The C503B series utilizes advanced materials to maintain performance in harsh environmental conditions common in traffic and advertising signage.

Replacement Considerations

Cross-reference with other C503B variants such as C503B-BAN or C503B-GAS if different colors are acceptable. Verify pinout and dimensional tolerances match the target PCB footprint. Check for updated manufacturing revisions that may affect lead frame composition or lens material properties.
