Procurement Notes

This component is classified as obsolete and is no longer manufactured by Cree LED. Procurement should focus on identifying verified substitute part numbers or alternative components that meet the required electrical and mechanical specifications. Verify compatibility with existing PCB layouts and driver circuits before sourcing replacements.

Selection Notes

Select this component only if legacy support is required, as it is discontinued. For new designs, consider modern alternatives within the Screen Master family or other Cree LED lines that offer similar optical characteristics and form factors. Ensure the replacement matches the 4 mm through-hole footprint and blue color requirements.

Part Context

The C4SMF-BJF-CS24Q4S2 belongs to the Screen Master series, which is engineered for demanding visual display environments. This series is known for providing bright and reliable light output suitable for large-format displays. The specific model utilizes a 4 mm oval package, distinguishing it from round or surface-mount variants in the broader portfolio.

Replacement Considerations

Available substitutes include similar components such as the 3474AN. Verify that any replacement maintains the same through-hole configuration, blue wavelength, and mechanical dimensions to ensure seamless integration into existing signage systems.
