Overview
The Citizen CL-426F-AA-SD is a discontinued RGB surface-mount LED indicator. It features a common cathode configuration with red, green, and blue LEDs emitting at peak wavelengths of 628nm, 530nm, and 470nm respectively. The device utilizes a 4-SMD no-lead package measuring 2.80mm in length, 0.85mm in width, and 0.35mm in height. Typical forward voltages are 2V for red, 2.7V for green, and 2.8V for blue. Luminous intensity values are 120mcd (red), 250mcd (green), and 62mcd (blue) at a test current of 5mA per color.
Feature Summary
- RGB tri-color emission within a single compact SMD package
- Common cathode electrical configuration for simplified circuit design
- Right-angle surface mount installation style
- RoHS3 compliant construction
Applications
- Status indication on electronic control boards
- Visual signaling in consumer electronics
- Interface lighting for appliance panels
Procurement Notes
Verify component availability as the CL-426F-AA-SD is officially listed as obsolete by the manufacturer. Confirm end-of-life status dates prior to procurement planning. Source replacement components from authorized distributors or secondary markets only if necessary. Ensure that any substitute parts match the required pinout and mechanical dimensions for existing PCB layouts.
Selection Notes
Select this component for applications requiring compact RGB indication in right-angle surface mount configurations. Consider the specific luminous intensity requirements for each color channel when designing optical paths. Verify compatibility with standard reflow soldering profiles for 4-SMD packages. Evaluate thermal management needs based on the specified forward voltage and test current parameters.
Part Context
This part belongs to the Citizen CL-426 series of RGB LEDs. The series offers various packaging options including different lens styles and lead configurations. The CL-426 family is designed for high-density mounting on printed circuit boards. Other variants in the series may differ in wavelength, intensity, or physical dimensions.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation due to the product's obsolete status. Engineers should consult official cross-reference guides or contact the manufacturer for approved alternatives. Ensure any replacement maintains the same common cathode configuration and package footprint.
