CL-505S-X-SD

Overview

The Citizen CL-505S-X-SD is a surface-mount RGB LED indicator in a 0404 (1.0x1.0 mm) package with a common anode configuration. It emits red at 615nm, green at 530nm, and blue at 470nm. Typical forward voltages are 1.85V for red and 2.7V/2.75V for green/blue. Rated at 5mA test current, it delivers luminous intensities of 40mcd (red), 220mcd (green), and 65mcd (blue). The component features a square lens with a flat top and measures 0.26mm maximum height.

Feature Summary

• Compact 0404 surface-mount form factor suitable for space-constrained designs
• Integrated RGB tri-color capability within a single package
• Common anode electrical configuration

Applications

• Status indication on compact electronic devices
• Backlighting for small displays or interfaces
• Indicator lights in portable consumer electronics

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging type, such as tape-and-reel or cut-tape, matches your assembly requirements. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) during storage planning. Cross-reference the manufacturer part number with distributor codes to avoid selection errors.

Selection Notes

Select this component when a minimal footprint is required for multi-color signaling. Ensure the driving circuit accommodates the distinct forward voltage differences between the red and green/blue channels. Verify that the required luminous intensity meets the application's visibility standards under ambient lighting conditions.

Part Context

This component belongs to the Citizen CL-505S series, which focuses on miniaturized LED solutions. The series supports various color combinations in standard SMD packages, enabling designers to implement complex visual feedback systems without increasing board space consumption.

Replacement Considerations

Consult official substitution lists for compatible RGB LEDs in the 0404 package. Verify pinout compatibility and spectral alignment before replacing.
