C503B-AAN-CA0C0252-015

Overview

The C503B-AAN-CA0C0252-015 is a Cree LED amber through-hole component in a 5 mm T-1 3/4 package. It features a round lens with a domed top and clear tint. Key electrical parameters include a forward voltage of 2.1 V, a maximum power dissipation of 130 mW, and a peak forward current rating of 20 mA. The device emits at a dominant wavelength of 591 nm with a luminous intensity of 12,000 mcd. It offers a narrow 15-degree viewing angle and complies with RoHS standards for lead-free manufacturing.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• Encapsulation resin contains UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the LED's operational life.
• Narrow 15-degree beam angle design enhances directionality for improved readability in bright ambient conditions.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0252-015 against the official Cree datasheet to confirm exact binning and optical characteristics. Ensure the procurement source provides valid RoHS compliance documentation. Confirm that the supplier handles bulk packaging correctly, as this component is typically supplied in quantities of 500 units per bag. Cross-reference the manufacturer part number to avoid confusion with similar variants in the C503B family.

Selection Notes

Select this component when a narrow 15-degree viewing angle is required for long-distance visibility in signage applications. The 591 nm amber wavelength offers high contrast against daylight backgrounds. Consider the 20 mA forward current limit and 130 mW power dissipation for thermal management in dense arrays. This through-hole package is suitable for PCB designs requiring robust mechanical mounting compared to surface-mount alternatives.

Part Context

This part belongs to the Cree C503B series of 5-mm Red and Amber Round LEDs. The series includes variants with different beam angles, such as 23 degrees (ABS/ABN) and 30 degrees (ACS/ACN). The AAN suffix specifically denotes the 15-degree narrow beam configuration. These components are engineered for high-brightness performance in demanding outdoor environments where reliability and color stability are critical.

Replacement Considerations

Direct substitutes within the same family include C503B-AAS-CA0C0252-015 for identical specifications or C503B-RAN-CA0C0252-015 if red emission is acceptable. Other angular variants like C503B-ABS or C503B-ACS offer wider viewing angles but share the same physical footprint and electrical ratings. Verify compatibility before swapping to ensure the application does not require the specific narrow-beam optics of the AAN model.
