CLM3C-RKW-CUBWAAA3

Overview

The CLM3C-RKW-CUBWAAA3 is a red surface-mount LED from Cree LED, housed in a 2-PLCC package with J-leads. It emits at a dominant wavelength of 624 nm and features a typical forward voltage of 2.1 V at a test current of 20 mA. The device has dimensions of 2.70 mm in length, 2.00 mm in width, and a maximum height of 1.40 mm. It offers a viewing angle of 120 degrees and a luminous intensity of 710 mcd. The lens is clear and rectangular with a flat top.

Feature Summary

• Features a flat top emitting surface designed for easy mating with light pipes.
• Provides a wide 120-degree viewing angle suitable for channel lettering applications.
• Utilizes a standard 2-SMD, J-lead PLCC package for surface mount installation.

Applications

• Channel lettering
• General backlighting
• Illumination

Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct wavelength and binning. Confirm that the J-lead package variant matches the target PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly planning. Ensure the ordering quantity aligns with the available tape and reel specifications.

Selection Notes

Select this component when a high-intensity red indicator is required for visible signage or illumination tasks. The 120-degree viewing angle ensures broad visibility compared to narrow-beam alternatives. The flat top design facilitates optical coupling with external light guides. Verify thermal management capabilities if operating near maximum rated currents.

Part Context

This part belongs to the CLM3C series of PLCC2 SMD LEDs from Cree LED. The series is characterized by its compact 2.7 x 2.0 mm footprint and standardized pin configuration. It serves as a direct replacement for older PLCC-style indicators while offering improved brightness and consistent color performance across production batches.

Replacement Considerations

Cross-reference with CLM3C-RKW-CUBVAAA3 for similar red emission characteristics. Verify mechanical compatibility of the J-lead package before substitution. Ensure electrical parameters such as forward voltage and test current remain within acceptable limits for the existing circuit design.
