Procurement Notes

Verify the specific suffix against official Cree documentation to confirm exact binning and optical characteristics. Confirm RoHS compliance status and check for any product change notices affecting lead frame or encapsulation materials before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring high visibility in outdoor environments due to its UV-resistant construction. Ensure circuit design accommodates the 2.1 V forward voltage drop and limits current to prevent exceeding the 130 mW power dissipation rating under varying thermal conditions.

Part Context

This part belongs to the C503B family of 5 mm round LEDs designed for readability in demanding outdoor settings. The ACS designation indicates a 30-degree viewing angle and amber coloration. These components are engineered for durability in signage and signal applications where long-term stability is critical.

Replacement Considerations

Consult official Cree databases for verified substitutes. Generic replacements may not match the specific UV inhibitor formulation or optical grade epoxy required for outdoor longevity.
