Procurement Notes

Verify the specific suffix against official Cree documentation to ensure correct optical and electrical characteristics. Confirm that the ordering code matches the required lens transparency and intensity rating. Cross-reference datasheet parameters with design requirements before procurement to avoid functional mismatches.

Selection Notes

Select this component when a high-brightness red indicator or illumination source is required in a compact SMD form factor. The PLCC-4 package facilitates standard reflow soldering processes. Ensure thermal management aligns with the specified operating temperature range for reliable long-term performance in the target application.

Part Context

This part belongs to the CLM4B series of single-color LEDs designed for general indication and illumination. The series utilizes advanced semiconductor technology to provide consistent color rendering and luminous intensity. It serves as a standard solution for PCB-mounted lighting needs where space constraints and brightness are critical factors.

Replacement Considerations

Direct substitutes require matching PLCC-4 footprint, 624 nm wavelength, and similar forward voltage. Verify pinout compatibility and thermal resistance characteristics. Consult manufacturer cross-reference lists for validated equivalent parts with identical mechanical and electrical specifications.
