C503B-ACS-CX0Z0342

Overview

The C503B-ACS-CX0Z0342 is a Cree LED amber round indicator with a 5mm T-1 3/4 radial through-hole package. It features a clear lens and emits at a dominant wavelength of 591nm. Typical forward voltage is 2.1V at 20mA test current, with a maximum power dissipation of 130mW. Luminous intensity ranges from 3000 to 8200 mcd, and the viewing angle is 30 degrees.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Stable light output maintained over the operational life of the component in demanding environments.

Applications

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

Procurement Notes

Verify RoHS compliance status and confirm lead times with authorized distributors. Check for Product Change Notifications regarding packaging or material updates. Ensure ordering suffixes match specific intensity binning requirements. Confirm availability as some variants may be restricted for new designs.

Selection Notes

Select this model for applications requiring high visibility in outdoor signage due to its UV-resistant epoxy construction. The 30-degree viewing angle balances beam spread and intensity. Verify thermal management capabilities against the 130mW maximum power dissipation rating for continuous operation.

Part Context

This component belongs to the Cree C503B family of 5mm red and amber round LEDs. The series is engineered for excellent readability in outdoor sign and signal applications. It utilizes advanced encapsulation technology to ensure reliability under harsh environmental conditions compared to standard indicators.

Replacement Considerations

Cross-reference with C503B-ACN-CX0Y0252 for similar specifications. Note that C503B-ACS-CYAZa341-030 is marked as Not Recommended for New Designs (NRND). Verify pin compatibility and luminous intensity bins before substitution.
