C503B-GCN-CB0C0781

Overview

The C503B-GCN-CB0C0781 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 emits at a dominant wavelength of 527 nm with a clear dome lens. The component operates with a typical forward voltage of 3.2 V and a maximum forward current of 30 mA, supporting a power rating of 120 mW. It features a 30-degree viewing angle and offers luminous intensity ranging from 5,860 to 32,900 mcd depending on binning. The device complies with RoHS standards and is suitable for general indication applications requiring high brightness.

Feature Summary

• High luminous intensity output for excellent readability in sunlight
• Stable light performance over extended operational periods
• Standard radial lead configuration for easy PCB integration

Applications

• Panel indicators for industrial equipment
• Status lights for consumer electronics
• General purpose visual signaling systems

Procurement Notes

Verify the specific suffix against official Cree LED documentation to confirm exact binning parameters such as luminous intensity and chromaticity coordinates. Ensure the ordering code matches the required packaging format, whether bulk or tape and reel. Confirm compliance requirements including RoHS status prior to finalizing procurement orders.

Selection Notes

Select this component when a standard 5 mm through-hole form factor is required for green indication. Consider the 30-degree beam width for applications needing moderate light dispersion. Verify that the 3.2 V forward voltage aligns with the driving circuit design and that the 120 mW power dissipation limit is respected within the thermal environment.

Part Context

This part belongs to the C503B family of round LEDs, which are known for superior light output compared to standard indicator lamps. The GCN designation typically indicates a green emission with a clear lens and a 30-degree viewing angle. These components are widely used in legacy and modern designs requiring reliable, high-brightness visible indication.

Replacement Considerations

Direct substitutes include other C503B-GCN variants with different intensity bins, such as C503B-GCN-CA0B0782 or C503B-GCN-CY0C0791. Cross-manufacturer replacements require matching the 5 mm T-1 3/4 package, 527 nm wavelength, and 30-degree viewing angle specifications.
