C503B-BCN-CX0Y0452

Overview

C503B-BCN-CX0Y0452 is a blue round LED from the Cree C503B series, 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 maximum forward current of 30 mA. The component features a clear colorless lens, a 30-degree viewing angle, and a luminous intensity of 12 cd. It operates within a temperature range of -40°C to +95°C and dissipates up to 120 mW.

Feature Summary

• Advanced optical-grade epoxy construction for high-temperature and moisture resistance
• UV inhibitors integrated into encapsulation resin to minimize sunlight degradation effects
• Stable light output performance maintained over extended operational periods

Applications

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

Procurement Notes

Verify the specific suffix configuration against official Cree documentation to ensure correct wavelength and binning specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement orders.

Selection Notes

Select this component for applications requiring reliable blue illumination in outdoor environments. The 30-degree viewing angle provides broader visibility compared to narrower beam variants. Ensure thermal management supports the 120 mW power dissipation rating during continuous operation.

Part Context

This part belongs to the C503B family of 5-mm round LEDs designed for superior readability in sunlight. The series utilizes advanced epoxy materials to withstand harsh environmental conditions, making it suitable for demanding signage and signal applications where long-term stability is critical.

Replacement Considerations

Consult official Cree substitution guides for compatible alternatives. Verify pinout compatibility and electrical parameters when considering cross-references from other manufacturers.
