C503B-GAN-CB0C0782

Overview

The C503B-GAN-CB0C0782 is a single-color green LED from the Cree LED C503B series, designed for through-hole mounting in a T-1 3/4 (5 mm) round package. It features a tinted dome lens with a clear finish and emits light at a dominant wavelength of 527 nm. The component operates with a forward current of 20 mA and a typical forward voltage of 3.2 V, delivering a luminous intensity of 38,000 mcd. It has a narrow viewing angle of 15 degrees and supports an operating temperature range from -40°C to +95°C.

Feature Summary

• High-intensity green emission optimized for excellent readability in sunlight
• Advanced optical-grade epoxy construction ensures superior high-temperature and high-moisture resistance
• Narrow 15-degree viewing angle provides focused directional light output
• Lead-free and RoHS-compliant design suitable for outdoor signal applications

Applications

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

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets and product change notifications. Confirm that the specific suffix matches the required electrical parameters, particularly the 527 nm wavelength and 38,000 mcd intensity. Ensure compliance with RoHS standards and check for any recent packaging or labeling updates documented in public PCNs before procurement.

Selection Notes

Select this component when a narrow beam angle and high luminous intensity are required for long-distance visibility. The 5 mm through-hole form factor suits legacy board designs. Verify thermal management capabilities for operation near the maximum rated temperature of +95°C. Consider the tinted lens characteristics for specific color perception requirements in outdoor environments.

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 viewing angles. The C503B-GAN designation specifically indicates a green LED with a 15-degree viewing angle, distinguishing it from the wider 30-degree CN series within the same product line.

Replacement Considerations

Publicly confirmed substitute part numbers include C503B-GCN-CA0B0892 and C503B-GCN-CY0C0791. These alternatives offer parameter equivalence but feature a 30-degree viewing angle instead of the 15-degree angle of the original part.
