Procurement Notes

Verify that the specific suffix matches the required binning parameters for color consistency and intensity. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering code aligns exactly with the requested lens style and electrical characteristics before finalizing procurement.

Selection Notes

Select this component for applications requiring high visibility in bright ambient light. The 30-degree beam angle offers a balance between focus and spread. Verify thermal management requirements against the 120 mW dissipation limit. Ensure circuit design accommodates the 4 V forward voltage drop at the specified operating current.

Part Context

This part belongs to the Cree C503 family of 5 mm round LEDs. The series is engineered for outdoor durability and long-term performance stability. It utilizes advanced encapsulation materials to resist environmental degradation while maintaining consistent optical output.

Replacement Considerations

Direct substitutes within the same series include C503B-BCN-CV0Z0461 or C503B-BAS-CY0Z0452, depending on the required viewing angle and intensity binning. Cross-reference datasheets to ensure identical pinout and mechanical dimensions.
