C503B-BCN-CW0X0451

Overview

The C503B-BCN-CW0X0451 is a blue light-emitting diode from the Cree LED series, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a 30-degree viewing angle and emits at a dominant wavelength of 480 nm. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA, dissipating up to 120 mW. Luminous intensity ranges from 2130 to 12000 mcd.

Feature Summary

• Constructed with advanced optical-grade epoxy for high temperature and moisture resistance
• Provides stable light output suitable for outdoor signal applications
• Ensures excellent readability in sunlight conditions

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm exact luminous intensity binning and wavelength tolerances. Ensure compatibility with standard through-hole mounting processes and verify RoHS compliance status for the specific manufacturing batch before integration into final assemblies.

Selection Notes

Select this component when a 30-degree beam spread is required for blue illumination. It serves as an alternative to the 15-degree variants within the same family. Confirm that the 4 V forward voltage aligns with the circuit design constraints and that the 5 mm form factor fits the mechanical enclosure requirements.

Part Context

This part belongs to the Cree 5-mm Blue and Green Round LED family. It shares the same physical dimensions and basic electrical characteristics with other models in the series, differing primarily in viewing angle and specific color performance metrics defined by the alphanumeric suffix codes.

Replacement Considerations

Direct substitutes include other C503B-BCN variants with matching 30-degree angles. Verify that any replacement maintains the 480 nm wavelength and compatible forward voltage specifications to ensure consistent optical performance.
