C503B-GCS-CB0C0781

Overview

The C503B-GCS-CB0C0781 is a single-color green LED from the Cree LED C503B series, housed in a T-1 3/4 (5 mm) round package. It features a tinted dome lens with clear transparency and a 30-degree viewing angle. The device operates at a forward current of 20 mA with a typical forward voltage of 3.2 V and a power rating of 120 mW. It emits light at a dominant wavelength of 527 nm with a luminous intensity ranging from 5860 to 32900 mcd. The component supports an operating temperature range from -40°C to +95°C.

Feature Summary

• Provides superior light output for excellent readability in sunlight
• Ensures extremely stable light output over long periods
• Constructed with advanced optical-grade epoxy for high temperature and moisture resistance

Applications

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

Procurement Notes

Verify that the specific suffix CB0C0781 matches the required binning for luminous intensity and wavelength within the standard C503B-GCS specifications. Confirm RoHS compliance status through the manufacturer's official documentation or authorized distributor declarations prior to procurement. Ensure the supplier provides valid traceability records for the batch code to guarantee component authenticity and quality assurance.

Selection Notes

Select this component when a 30-degree viewing angle is required for green indication applications. Compare against the C503B-GAS/GAN variants if a narrower 15-degree beam is needed. Consider the 5 mm radial mount form factor for through-hole PCB layouts. Evaluate the 120 mW power rating against thermal management requirements in enclosed signal housing designs.

Part Context

This part belongs to the Cree LED C503B family of 5-mm round LEDs, designed for outdoor durability. The GCS designation indicates a green color variant with a 30-degree viewing angle. This series is engineered for harsh environments, utilizing epoxy materials that resist degradation from UV exposure and humidity, ensuring reliable performance in critical signaling infrastructure.
