C503B-BCS-CW0Y0451-030

Overview

The C503B-BCS-CW0Y0451-030 is a blue light-emitting diode from the Cree LED family, housed in a 5 mm (T-1 3/4) through-hole package. It emits at a dominant wavelength of 470 nm with a forward voltage of 4 V and a maximum forward current of 30 mA. The component features a 30-degree viewing angle and a circular clear lens. It operates within a temperature range of -40 °C to +95 °C and has a maximum power dissipation of 120 mW.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize effects of long-term direct sunlight exposure.
• Provides extremely stable light output over long periods for dependable performance.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)

Procurement Notes

Verify the specific suffix CW0Y0451-030 against official Cree datasheets to confirm exact binning and luminous intensity ratings. Ensure RoHS compliance documentation matches the manufacturing batch. Confirm that the 5 mm T-1 3/4 lead spacing aligns with your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when high readability in sunlight is required for outdoor signage applications. The 30-degree viewing angle offers a wider beam compared to narrow-angle variants. Verify that the 4 V forward voltage is compatible with your circuit design and that the 120 mW power dissipation rating meets thermal management constraints.

Part Context

This part belongs to the Cree 5-mm Blue and Green Round LED series, designed specifically for outdoor sign and signal applications. The series utilizes robust encapsulation materials to ensure durability and consistent performance under harsh environmental conditions, including high heat and moisture exposure.

Replacement Considerations

Cross-reference with other C503B-BCS variants for different luminous intensity bins or viewing angles. Verify mechanical compatibility with existing footprints when substituting with similar 5 mm through-hole LEDs from other manufacturers.
