C4SMK-RJS-CT24QBB1

Overview

The C4SMK-RJS-CT24QBB1 is a red discrete LED from the Screen Master series, manufactured by Cree LED. It features a 4mm oval lens with a dominant wavelength of 621nm to 624nm and a typical forward voltage of 2V. The component utilizes through-hole mounting with radial leads. Key electrical parameters include a forward current of 20mA and a power rating of 130mW. Optical performance varies across sources, citing light intensities of 2 cd or 1591 mcd. The lens transparency is described as clear or water-clear.

Feature Summary

• Red illumination with high visibility for indicator applications
• Oval lens design providing distinct visual profile
• Through-hole construction for reliable PCB integration

Applications

• Panel status indicators
• Equipment power signaling
• Control board visual feedback

Procurement Notes

Verify datasheet specifications against supplier documentation due to conflicting intensity data (2 cd vs 1591 mcd) and wavelength variations (621nm vs 624nm). Confirm package orientation and lead form before ordering. Ensure RoHS compliance requirements are met if applicable, as some listings indicate non-compliance.

Selection Notes

Select this component for applications requiring a standard 4mm oval red LED with through-hole compatibility. Consider the specific optical intensity requirement when choosing between available variants, as published values differ significantly. Verify the exact wavelength needed for color consistency in multi-LED assemblies.

Part Context

This part belongs to the Screen Master series of discrete LEDs. It serves as a general-purpose indicator component within the broader category of red through-hole LEDs. The 4mm oval form factor distinguishes it from round or rectangular alternatives in similar product lines.

Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Cross-referencing requires matching the 4mm oval footprint, 2V forward voltage, and red spectral output.
