C503B-RAS-CZ0A0AA1

Overview

The C503B-RAS-CZ0A0AA1 is a single-color red light-emitting diode from the Cree LED family. It utilizes a 5 mm (T-1 3/4) through-hole package with a round, colorless lens. The component emits at a dominant wavelength of 624 nm and provides a luminous intensity range of 5860 to 23500 mcd. It features a narrow 15-degree viewing angle and operates with a maximum forward current of 20 mA. The device has a forward voltage of approximately 2.1 V and a power rating of 130 mW.

Feature Summary

• Advanced optical-grade epoxy encapsulation ensures superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, maintaining stable light output over the product lifecycle.
• Narrow 15-degree beam angle concentrates light emission for enhanced readability in signaling applications.

Applications

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

Procurement Notes

Verify the specific bin code suffix to confirm exact luminous intensity and wavelength parameters before procurement. Confirm RoHS compliance status via the manufacturer datasheet. Check component lifecycle status as some variants may be recommended against new designs. Ensure ordering quantities align with bulk packaging requirements specified by the distributor.

Selection Notes

Select this component when high-intensity red illumination with a focused beam is required for long-distance visibility. The 15-degree viewing angle distinguishes it from wider-angle alternatives like the RBS or RCS series. Consider the 5 mm T-1 3/4 form factor for standard through-hole mounting constraints in signage assemblies.

Part Context

This part belongs to the C503B-RAS/RAN family of 5-mm Red LEDs designed for robust outdoor environments. It shares the same physical footprint and electrical characteristics as other members of the R-series but differs in optical intensity bins. The series is engineered specifically for high-readability applications requiring reliable performance under varying weather conditions.

Replacement Considerations

Direct substitutes within the same family include C503B-RAN-CZ0A0AA1, which offers similar specifications. For different beam angles, consider C503B-RBS or C503B-RCS variants. Verify that replacement parts match the required luminous intensity bin and forward voltage tolerance.
