C503B-ACS-CX0Z0251

LED Indication - Discrete Overview

The C503B-ACS-CX0Z0251 is a single-color amber LED from the Cree C503B series, designed for through-hole mounting in a 5 mm (T-1 3/4) round package. It features a clear dome lens and emits light at a dominant wavelength of 591 nm. The component operates with a typical forward voltage of 2.1 V at a test current of 20 mA, delivering a luminous intensity of approximately 8090 mcd. It has a maximum power dissipation rating of 130 mW and supports a viewing angle of 30 degrees. The device is rated for operation between -40°C and +100°C and complies with RoHS standards.

LED Indication - Discrete Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors to ensure stability against long-term sunlight exposure.
• Provides superior high-temperature and high-moisture resistance suitable for demanding outdoor environments.
• Features a clear dome lens design optimized for excellent readability in signal applications.

LED Indication - Discrete Applications

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

LED Indication - Discrete Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm exact luminous intensity binning and wavelength tolerances. Ensure that the selected variant matches the required forward voltage characteristics for the target circuit design. Confirm availability status as some variants may be subject to supply constraints or obsolescence notices.

LED Indication - Discrete Selection Notes

Select this component when high visibility and environmental durability are required for outdoor signage. The 30-degree viewing angle offers a balance between beam spread and intensity. Consider the 2.1 V forward voltage drop for driver compatibility. Verify thermal management requirements given the 130 mW power dissipation limit in enclosed assemblies.

LED Indication - Discrete Part Context

This part belongs to the C503B family of 5-mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The ACS designation typically indicates an amber LED with a 30-degree viewing angle and standard intensity levels within the product line.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other C503B-ACS variants with different intensity bins, such as C503B-ACS-CX0Z0252. Cross-reference with generic 5mm T-1 3/4 amber LEDs only if electrical parameters and mechanical dimensions are strictly matched.
