Procurement Notes

Verify component status as this part may be marked Not Recommended for New Designs (NRND). Confirm RoHS compliance details via official datasheets before integration. Check for alternative availability if long-term supply stability is required for production cycles.

Selection Notes

Select this component when high visibility in direct sunlight is critical due to its superior light output. The 15-degree viewing angle suits applications requiring precise light directionality. Ensure circuit design accommodates the 2.1 V forward voltage drop and 20 mA operating current for optimal performance.

Part Context

This component belongs to the C503B series of 5-mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different beam angles (15, 23, and 30 degrees). The AAN suffix specifically denotes the amber variant with a 15-degree viewing angle, distinguishing it from wider-angle models like ACS or ABS.
