Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official datasheets. Confirm that the specific suffix matches the required electrical parameters, particularly the 527 nm wavelength and 38,000 mcd intensity. Ensure the procurement channel provides valid RoHS compliance documentation. Check for any product change notifications or obsolescence notices prior to ordering to ensure supply continuity.

Selection Notes

Select this component when high-intensity green illumination is required for outdoor visibility. The 15-degree beam angle suits applications needing focused light direction. Verify that the 3.2 V forward voltage aligns with the system's drive circuitry. Consider the T-1 3/4 package size for mechanical fitment constraints. Evaluate the operating temperature range against the environmental conditions of the intended installation site.

Part Context

This part belongs to the Cree LED C503B series of 5-mm round LEDs, which includes variants with different colors and beam angles. The 'GAS' designation typically indicates a green color with a 15-degree viewing angle. This series is engineered for durability in harsh environments, utilizing specialized epoxy materials to maintain optical performance under thermal and humidity stress common in outdoor signaling infrastructure.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 527 nm wavelength, 38,000 mcd intensity, 15-degree viewing angle, and T-1 3/4 package dimensions. Verify electrical compatibility regarding forward voltage and current requirements before substituting with other manufacturers' components.
