C503B-RAN-CZ0A0AA2

Overview

The C503B-RAN-CZ0A0AA2 is a single-color red LED from the Cree series, designed for through-hole mounting in a 5 mm (T-1 3/4) package. It features a clear lens with a 15-degree viewing angle and emits at a dominant wavelength of 624 nm. The component operates with a forward voltage of 2.1 V and a maximum forward current of 20 mA. It delivers a luminous intensity range of 5860 to 23500 mcd and has a maximum power dissipation of 120 mW.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance suitable for outdoor environments.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Ensures stable light output over the operational life of the LED under harsh weather conditions.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official Cree documentation to ensure correct binning and optical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors. Cross-reference datasheet parameters such as forward voltage and luminous intensity ranges to match application requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high visibility in bright outdoor conditions due to its narrow 15-degree beam angle. Ensure circuit design accommodates the 2.1 V forward voltage drop and 20 mA test current. Consider the thermal management capabilities provided by the 120 mW power dissipation rating for sustained operation in enclosed or high-ambient temperature environments.

Part Context

This part belongs to the C503B family of 5-mm round LEDs manufactured by Cree LED. The family includes various colors and beam angles optimized for readability in outdoor signage. The RAN designation specifically indicates a red LED variant within this robust, weather-resistant product line designed for demanding signal applications.

Replacement Considerations

Direct substitutes include other C503B-series red LEDs with compatible beam angles, such as C503B-RAS or C503B-RCS, depending on the required field of view. Verify mechanical footprint compatibility and electrical specifications when considering alternative manufacturers' 5 mm through-hole red LEDs.
