C503B-BAS-CZ0A0452

Overview

The C503B-BAS-CZ0A0452 is a blue light-emitting diode from the Cree LED C503B series, housed in a 5 mm (T-1 3/4) radial through-hole package. It emits at a dominant wavelength of 475 nm with a clear, colorless lens. Key electrical parameters include a forward voltage of 4 V and a maximum forward current of 30 mA. The device offers a luminous intensity of 16.8 cd and a narrow viewing angle of 15 degrees. It operates within a temperature range of -40°C to +95°C and complies with RoHS standards.

Feature Summary

• Provides superior light output for excellent readability in sunlight
• Ensures dependable performance with extremely stable light output over long periods
• Constructed with advanced optical-grade epoxy for high temperature and moisture resistance

Applications

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

Procurement Notes

Verify the specific suffix 'CZ0A0452' against official datasheets to confirm the 475 nm wavelength and 16.8 cd intensity specifications. Confirm that the component status is active for new designs, as some variants in this family may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with standard through-hole assembly processes.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for focused visibility in outdoor signage applications. The 5 mm round package allows for easy integration into existing PCB layouts designed for T-1 3/4 LEDs. Consider the 4 V forward voltage drop when designing drive circuits to ensure appropriate current limiting resistors are used.

Part Context

This part belongs to the Cree LED C503B family of 5-mm Blue and Green Round LEDs. The family includes variants with different wavelengths, intensities, and viewing angles (15 or 30 degrees). These LEDs are engineered for high-brightness indicator and signage applications where durability and consistent optical performance are critical.

Replacement Considerations

Direct substitutes within the same family include C503B-BAN-CZ0A0452 (470 nm, 23500 mcd) and C503B-BAS-CY0Z0452 (470 nm, 11000 mcd). Verify that the replacement maintains the required 15-degree viewing angle and 5 mm package dimensions for mechanical fit.
