C503B-RAS-CA0B0AA2

Overview

The C503B-RAS-CA0B0AA2 is a red light-emitting diode from the Cree LED C503B series, designed for discrete indication applications. It features a 5 mm (T-1 3/4) radial through-hole package with a round lens and domed top. The component emits light at a peak wavelength of 624 nm with a viewing angle of 15 degrees. Key electrical parameters include a forward voltage of 2.1 V and a maximum continuous forward current of 20 mA. The device has a maximum power dissipation rating of 120 mW and complies with RoHS standards.

Feature Summary

• Provides high-intensity red illumination suitable for visual status indication
• Features a 15-degree narrow beam angle for focused light projection
• Utilizes a standard 5 mm T-1 3/4 radial leaded package for easy mounting

Applications

• Panel indicator lights for electronic equipment
• Power supply status signaling
• Control board activity indicators

Procurement Notes

Verify the specific suffix CA0B0AA2 to confirm the 624 nm red wavelength and 20 mA current rating. Ensure the procurement matches the 5 mm radial package type. Confirm RoHS compliance requirements are met for the target assembly process. Cross-reference the manufacturer datasheet for thermal derating curves before finalizing design specifications.

Selection Notes

Select this component when a narrow 15-degree viewing angle is required for precise directional indication. The 2.1 V forward voltage makes it compatible with low-voltage logic circuits. Consider the 5 mm radial form factor for standard PCB hole spacing. Evaluate the 120 mW power dissipation limit against the expected operating temperature range to ensure reliability.

Part Context

This part belongs to the Cree C503B family of 5 mm round LEDs. The family includes various colors such as red, amber, green, blue, and yellow. The C503B series is characterized by its consistent mechanical dimensions across color variants, allowing for interchangeable design layouts while changing only the optical output characteristics.

Replacement Considerations

Direct substitutes within the same Cree C503B series include C503B-RAN-CZ0C0AA2 or other C503B-Rxx variants with matching 15-degree beam angles and 5 mm packages. Verify that alternative parts maintain the 20 mA forward current and 2.1 V forward voltage specifications to ensure circuit compatibility.
