C503B-GAN-CB0C0781

Overview

The C503B-GAN-CB0C0781 is a green through-hole LED from the Cree LED C503B series, housed in a 5 mm (T-1 3/4) radial package. It features a clear lens with a 15-degree viewing angle and emits light at a dominant wavelength of 527 nm. The component operates with a typical forward voltage of 3.2 V and a maximum power dissipation of 120 mW. It provides a luminous intensity range of 16,800 to 90,500 mcd at a test current of 20 mA. Designed for robust performance, it complies with RoHS standards and supports operating temperatures from -40 °C to +95 °C.

Feature Summary

• High-intensity green emission optimized for excellent readability in direct sunlight
• Advanced optical-grade epoxy construction ensures superior resistance to high temperature and moisture
• Stable light output maintained over extended operational periods

Applications

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

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact luminous intensity binning and wavelength tolerances. Confirm current availability status as some variants may be subject to production changes or end-of-life notifications. Ensure compatibility with existing PCB footprints and thermal management requirements for outdoor signage environments.

Selection Notes

Select this component when high brightness and narrow beam visibility are required for daylight-readable applications. The 15-degree viewing angle directs light efficiently toward the viewer. Consider the 5 mm T-1 3/4 form factor for standard through-hole mounting processes. Evaluate environmental sealing needs given the epoxy lens material's moisture resistance properties.

Part Context

This part belongs to the C503B family of 5 mm round LEDs manufactured by Cree LED. The series includes blue and green variants with different beam angles, specifically the 15-degree GAN/GAS sub-series and the 30-degree GCN/GCS sub-series. These components are engineered for demanding outdoor signaling applications requiring durability and consistent photometric performance.

Replacement Considerations

Direct substitutes within the same family include C503B-GAN-CB0C0891 and C503B-GAN-CC0D0781. Verify that alternative suffixes match the required luminous intensity and wavelength specifications before substitution.
