C566C-BFF-CT0U0341

Overview

The C566C-BFF-CT0U0341 is a single-color blue LED from the Screen Master family, manufactured by Cree LED. It utilizes a T-1 3/4 (5 mm) oval package with through-hole radial mounting. The component emits light at a wavelength of 470 nm with a typical forward voltage of 3.4 V and a forward current rating of 20 mA. Optical performance includes an intensity of 1500 mcd and a viewing angle of 70 degrees by 35 degrees. The lens features a tinted blue color with clear transparency and an oval dome shape. Physical dimensions are 5.2 mm in length, 4.6 mm in width, and 7.8 mm in height. It operates within a temperature range of -40 °C to +95 °C and has a power rating of 140 mW.

Feature Summary

• Features a tinted blue oval dome lens for directional light emission.
• Designed for through-hole radial mounting on printed circuit boards.
• Provides high-intensity blue illumination suitable for indicator applications.

Applications

• Panel status indicators
• Control interface lighting
• Equipment status signaling

Procurement Notes

Verify component authenticity against manufacturer specifications due to end-of-life status. Confirm lead times with authorized distributors as availability may be limited. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Validate pin compatibility with existing PCB footprints before integration. Review product change notifications for any recent manufacturing updates.

Selection Notes

Select this component when a standard 5 mm oval form factor is required for blue indication. Consider the 3.4 V forward voltage drop for circuit design calculations. Evaluate thermal management requirements given the 140 mW power rating. Compare optical intensity against visibility needs for the specific application environment. Verify mechanical clearance for the 7.8 mm height dimension.

Part Context

This part belongs to the Screen Master series of 5 mm oval LEDs, known for consistent optical performance and reliable through-hole construction. The C566C prefix denotes the specific package style and electrical characteristics within the Cree LED portfolio. This series is widely used in industrial and commercial electronics for visual feedback.

Replacement Considerations

Check for direct substitutes within the C566C family such as C566C-BFE-CU0V0341 or C566C-BFN-CT0U0341. Verify that alternative parts match the 5 mm oval footprint and 470 nm wavelength. Ensure forward voltage and current ratings remain compatible with the existing drive circuitry.
