Procurement Notes

Verify the specific suffix CW0X against official Cree documentation to confirm exact luminous intensity binning and wavelength tolerance. Ensure the procurement channel provides original manufacturer packaging or certified authenticity to guarantee component reliability. Cross-reference the part number with the latest datasheet revisions to confirm compliance with current environmental standards such as RoHS.

Selection Notes

Select this component for applications requiring high-intensity blue illumination with a wide 30-degree viewing angle. It is suitable for environments demanding high temperature and moisture resistance due to its optical-grade epoxy construction. Consider the 4 V forward voltage and 30 mA current limits when designing drive circuits. Verify that the 5 mm T-1 3/4 package fits the mechanical constraints of the target assembly.

Part Context

This component belongs to the Cree 5-mm Blue and Green Round LED family, specifically the BCN variant which denotes a 30-degree viewing angle. The C503B series is designed for outdoor signal and sign applications where durability and brightness are critical. It represents a standard through-hole solution within Cree's portfolio of application-optimized LED products.

Replacement Considerations

Direct substitutes within the same family include C503B-BCN-CV0Z0461 (480 nm) and C503B-BCS variants (15-degree angle). Verify electrical parameters and mounting dimensions before substitution. Consult official Cree documentation for approved pin-compatible alternatives.
