C503B-GCN-CY0C0791

Overview

The C503B-GCN-CY0C0791 is a green single-color LED from the Cree series, featuring a 5 mm (T-1 3/4) through-hole package with two pins. It emits light at a main wavelength of 535 nm with a luminous intensity of 32.9 cd and a viewing angle of 30 degrees. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA, dissipating up to 120 mW. It includes a colorless, clear, round lens measuring 8.8 x 5 mm.

Feature Summary

• Provides high-intensity green emission at 535 nm for clear visual indication
• Features a standard 5 mm T-1 3/4 radial leaded package for easy insertion
• Includes a transparent, colorless dome lens for unobstructed light transmission

Applications

• General purpose electronic status indicators
• Panel-mounted equipment signal lights
• Consumer appliance control interfaces
• Industrial machinery operational displays

Procurement Notes

Verify the specific suffix CY0C0791 against official Cree LED documentation to confirm binning and optical tolerances. Ensure compatibility with standard 5 mm PCB footprints. Confirm RoHS compliance status for your region. Check for any recent product change notices affecting lens material or lead composition before finalizing orders.

Selection Notes

Select this component when a bright green indicator is required in a standard through-hole design. The 30-degree viewing angle suits direct-line-of-sight applications. Consider thermal management if operating near the 120 mW power limit. Verify that the 4 V forward voltage aligns with the driving circuit capabilities.

Part Context

This part belongs to the C503B family of LEDs, which are designed for general illumination and indication. The C503B series offers various colors and intensities within the 5 mm form factor. Cree LED manufactures these components using established semiconductor processes to ensure consistent performance across production batches.

Replacement Considerations

Direct substitutes include other 5 mm green LEDs with similar 535 nm wavelengths and 30 mA ratings. Cross-reference specifications for forward voltage and physical dimensions to ensure mechanical fit. Verify that alternative parts meet the same 30-degree viewing angle requirements.
