Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Cree LED. Verification of availability should focus on identifying valid substitute part numbers or checking secondary market sources, as direct procurement from the manufacturer is not possible. Ensure any replacement matches the original electrical and mechanical specifications to maintain system compatibility.

Selection Notes

Select this component for applications requiring high-brightness blue illumination in oval form factors. The Screen Master series is engineered for visibility in public signage environments. Consider the specific luminous intensity requirements and thermal management needs when integrating into existing circuit designs, noting that alternative packages may offer different optical characteristics.

Part Context

The C4SMG-BJF-CR24Q4T2 belongs to the Screen Master family of 4-mm oval LEDs. This series is characterized by its specialized optical design for large-format displays. The 'BJF' suffix typically denotes blue color and specific binning, while the full part number identifies the precise intensity grade and packaging configuration within the product line.

Replacement Considerations

Available substitutes include similar components such as HLMP series LEDs. Verify that replacements match the 475 nm wavelength, 20 mA forward current, and oval lens dimensions to ensure proper fit and function in existing signage assemblies.
