C503B-AAS-CY0B0252

Overview

Cree LED C503B-AAS-CY0B0252 is a through-hole amber LED in a 5mm (T-1 3/4) radial package. It features a clear round lens with a domed top and emits at a dominant wavelength of 591 nm. The component has a typical forward voltage of 2.1 V and a luminous intensity range of 5860 to 23500 mcd. It operates with a maximum forward current of 20 mA and offers a narrow 15-degree viewing angle.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the product lifespan.

Applications

• Electronic Signs & Signals
• Motorway Signs
• Variable-Message Signs

Procurement Notes

Verify the specific suffix CY0B0252 against the official Cree datasheet to confirm exact binning parameters. Ensure the selected variant matches the required luminous intensity and wavelength tolerances for the target application. Confirm RoHS compliance status and packaging options directly with the manufacturer or authorized distributors before finalizing procurement.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for focused visibility in signage applications. The 5mm T-1 3/4 through-hole package facilitates standard PCB mounting. Consider the 2.1V forward voltage drop for circuit design. Verify that the 20mA maximum forward current rating aligns with the system's power budget and thermal management capabilities.

Part Context

The C503B-AAS series belongs to Cree LED's family of 5mm red and amber round LEDs designed for high-readability outdoor environments. This specific model utilizes an advanced epoxy encapsulation technology optimized for long-term stability under harsh weather conditions and continuous UV exposure.

Replacement Considerations

Consult the official C503B datasheet for cross-reference information. No public substitute part numbers are confirmed in the provided documentation. Direct replacement requires matching the 5mm radial package, 15-degree viewing angle, and electrical characteristics.
