C5SMF-BJN-CT14Q4T1

Overview

The C5SMF-BJN-CT14Q4T1 is a single-color blue LED from the Screen Master family, designed for through-hole mounting in a T-1 3/4 (5 mm) oval package. It emits light at a wavelength of 470 nm with a typical forward voltage of 3.4 V and a forward current of 20 mA. The component features an oval lens shape with dimensions of 5.1 mm x 3.7 mm and a height of 7 mm. It provides a luminous intensity of 1400 mcd and operates within a temperature range of -40°C to +95°C.

Feature Summary

• Oval-shaped radiation pattern optimized for wide viewing angles
• High luminous intensity suitable for clear visibility applications
• Through-hole construction for robust mechanical mounting

Applications

• Variable-message signs
• Passenger-information displays
• Industrial status indicators

Procurement Notes

Verify the specific suffix CT14Q4T1 against manufacturer documentation to confirm binning and packaging details. Check for End-of-Life announcements or Product Change Notifications as Cree LED frequently updates component specifications. Ensure compatibility with existing thermal management designs given the 140 mW power rating.

Selection Notes

Select this component when a wide viewing angle and high brightness are required for blue illumination. The oval form factor distinguishes it from standard round LEDs, offering better directional control for signage. Verify that the 3.4 V forward voltage aligns with the system's drive circuit capabilities.

Part Context

This part belongs to the C5SMF Screen Master series, which specializes in oval LEDs for information display applications. The series is characterized by its unique radiation pattern and high intensity, making it distinct from general-purpose indicator LEDs. It shares the same physical footprint as other C5SMF variants but differs in optical and electrical characteristics.

Replacement Considerations

Direct substitutes include other C5SMF-BJN variants with matching electrical parameters. Cross-reference with C5SMF-BJS or C5SMF-BJF models if different intensity levels are acceptable. Always verify pinout and dimensional tolerances before substitution.
