1003UYD/S530-A3

Overview

The 1003UYD/S530-A3 is a single-color yellow LED manufactured by Everlight Electronics. It utilizes a T-1 (3mm) round lens package with two leads for through-hole mounting. The component emits light at a peak wavelength of 592nm, classified as yellow. It features a standard diffused lens configuration to provide a wide viewing angle. Electrical characteristics include a forward voltage typically around 2.1V and a maximum forward current rating suitable for general indicator applications.

Feature Summary

• Emits distinct yellow light at a 592nm peak wavelength
• Features a 3mm T-1 round diffused lens package
• Designed for through-hole PCB mounting

Applications

• Panel status indicators
• Power supply visual feedback
• General electronic equipment signaling

Procurement Notes

Verify the specific suffix S530-A3 against the manufacturer's latest datasheet to confirm exact binning and optical tolerances. Ensure the ordering part number matches the required lead angle and lens type specifications for your assembly process.

Selection Notes

Select this component when a standard 3mm yellow indicator is required for through-hole assembly. Consider the 592nm peak wavelength for visibility requirements and verify that the forward voltage drop aligns with the circuit drive capabilities.

Part Context

This model belongs to Everlight's standard discrete LED product line. It represents a common through-hole variant used in consumer electronics and industrial control panels where reliable visual signaling is necessary.

Replacement Considerations

Cross-reference with other 3mm yellow LEDs from Everlight such as the 1003SURD series for red alternatives or different wavelength variants. Verify mechanical footprint compatibility before substituting with components from other manufacturers.
