C503B-ABN-CX0Y0342

Overview

The C503B-ABN-CX0Y0342 is a Cree LED amber single-color light-emitting diode housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a domed top and clear surface. The component operates at a forward voltage of 2.1 V and supports a maximum forward current of 20 mA, with a power rating of 130 mW. It emits amber light at a dominant wavelength of 591 nm with a luminous intensity of 6000 mcd. The viewing angle is 15 degrees, and it complies with RoHS standards.

Feature Summary

• Utilizes advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize sunlight exposure effects.
• Provides stable light output over the life of the LED for outdoor applications.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct lens shape and intensity binning. Confirm availability status as some variants may be marked as Not Recommended for New Designs. Cross-reference pinout and thermal characteristics with the target PCB design before finalizing procurement orders.

Selection Notes

Select this component for applications requiring a narrow 15-degree beam angle and high visibility in direct sunlight. Ensure the driving circuit limits current to 20 mA to maintain the 130 mW power dissipation limit. Consider the operating temperature range of -40 C to +100 C for environmental suitability.

Part Context

This part belongs to the Cree C503B series of 5-mm round LEDs, designed for robust performance in harsh environments. The series offers various viewing angles and intensities, utilizing UV-stable materials to ensure longevity in outdoor signage and signal applications where readability is critical.

Replacement Considerations

Check for C503B-ACN or C503B-AAN variants if different viewing angles are required. Verify compatibility with existing footprints and electrical parameters when substituting other manufacturers' 5 mm amber LEDs.
