Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Cree LED. Verification of availability should focus on finding parametric equivalents or authorized distributors holding remaining stock. Direct procurement from the manufacturer is not possible. Ensure any substitute parts match the electrical and mechanical specifications required for the specific application environment.

Selection Notes

Select this part only if the specific oval form factor and viewing angles are critical for the optical design. Due to its obsolete status, engineers must evaluate alternative components that maintain the same pin configuration and luminous intensity. Verify that replacement LEDs meet the required forward voltage and current ratings to ensure compatibility with existing driver circuits without modification.

Part Context

The C5SMF-BJS-CS14Q4T2 belongs to the Screen Master family of 5-mm oval LEDs. This series is engineered for high-brightness applications requiring specific beam patterns. The blue variant provides distinct visual signaling capabilities suitable for outdoor or high-ambient-light environments where clear indication is necessary for public information dissemination.

Replacement Considerations

Available substitutes include parametric equivalents within the C5SMF series. Cross-reference models such as C5SMF-BJS-CR14Q4T1 for similar electrical characteristics. Ensure the replacement maintains the 5.1 mm x 3.7 mm lens size and 100° x 40° viewing angle to preserve optical performance in signage applications.
