C503B-BCS-CX0Y0451

Overview

The C503B-BCS-CX0Y0451 is a single-color blue LED from the Cree Pro9 series, housed in a T-1 3/4 (5 mm) through-hole package. It features a round lens with a domed top and clear tint. Key electrical parameters include a forward voltage of 3.2 V at a forward current of 20 mA, with a power rating of 120 mW. The device emits light at a peak wavelength of 480 nm, delivering a luminous intensity of 6190 mcd. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• High reliability construction suitable for demanding environments
• Through-hole mounting configuration for standard PCB integration
• Domed lens design providing a wide viewing angle

Applications

• Industrial control panel indicators
• Medical equipment status displays
• Automotive instrumentation clusters

Procurement Notes

Verify component authenticity against official datasheets before integration. Confirm that the specific ordering suffix matches the required electrical characteristics, as variations exist within the product family. Ensure storage conditions comply with moisture sensitivity levels to maintain performance integrity upon installation.

Selection Notes

Select this component when high luminous intensity and extended thermal stability are required for blue indicator applications. The 5 mm through-hole form factor ensures compatibility with legacy board designs. Consider the 120 mW power dissipation limit when designing thermal management solutions for dense arrays.

Part Context

This part belongs to the Cree Pro9 LED series, which is engineered for superior reliability compared to standard variants. The C503B designation indicates the 5 mm T-1 3/4 package style. The suffix BCS specifies the blue color, clear tint, and round dome lens configuration unique to this model.

Replacement Considerations

Direct substitutes within the same series include C503B-BCN-CV0Z0461, though it exhibits different electrical parameters such as a 4 V forward voltage. Verify mechanical fit and spectral output when cross-referencing other blue LEDs in the 5 mm package category.
