C503B-GCS-CZ0B0781-030

Overview

The C503B-GCS-CZ0B0781-030 is a green single-color LED from the Cree LED C503B series, housed in a standard 5 mm (T-1 3/4) through-hole package. It features a round lens with a 30-degree viewing angle and emits at a dominant wavelength of 527 nm. The component operates with a forward voltage of 4 V and a maximum forward current of 30 mA, dissipating up to 120 mW. Luminous intensity ranges from 5860 to 32900 mcd.

Feature Summary

• Provides superior light output for excellent readability in sunlight
• Ensures extremely stable light output over long periods of time
• Features dependable performance suitable for indicator applications

Applications

• Sunlight-readable indicators
• Panel status indicators
• General purpose signaling

Procurement Notes

Verify the specific luminous intensity bin and packaging configuration against the manufacturer's latest datasheet. Confirm RoHS compliance status and check for any recent product change notifications or lifecycle updates before finalizing procurement plans.

Selection Notes

Select this component when a 30-degree beam spread is required for wider visibility compared to the 15-degree variants. Ensure the circuit design accommodates the 4 V forward voltage drop and limits current to 30 mA to maintain the 120 mW power dissipation rating within safe operating limits.

Part Context

This part belongs to the C503B family of 5-mm round LEDs designed for high-brightness applications. The 'GCS' suffix denotes the green color variant with a 30-degree viewing angle, distinguishing it from the narrower 15-degree GAN/GAS models within the same physical footprint.

Replacement Considerations

Direct substitutes include other C503B-GCS variants with different intensity bins or packaging options. Cross-reference with equivalent 5 mm T-1 3/4 green LEDs from other manufacturers only if electrical parameters and mechanical dimensions are strictly matched.
