1003SUGD/S400-A4

Overview

The 1003SUGD/S400-A4 is a single-color green light-emitting diode manufactured by Everlight Electronics Co Ltd. It utilizes a through-hole mounting style with a 3.0 mm round lens package. The component emits green light at a wavelength of 525 nm and features a diffused lens finish. Electrical characteristics include a forward voltage of 3.3 V and a rated power of 110 mW. The device operates within a temperature range of -40 °C to +85 °C.

Feature Summary

• Diffused lens design for broad light distribution
• Through-hole construction for standard PCB integration
• Green emission optimized for visual indication

Applications

• Panel status indicators
• Equipment power signaling
• Consumer electronics front panels

Procurement Notes

Verify the specific suffix A4 against the manufacturer datasheet to confirm lead-free compliance and packaging format. Ensure the supplier provides traceable documentation matching the 1003 series specifications. Cross-reference the 3.0 mm radial dimensions with the target assembly requirements before finalizing orders.

Selection Notes

Select this component when a 3.0 mm form factor is required for green indication applications. The diffused lens option provides wider viewing angles compared to clear variants. Confirm that the 3.3 V forward voltage aligns with the driving circuit logic levels and current limiting resistors.

Part Context

This part belongs to the 1003 series of 3.0 mm round type LED lamps produced by Everlight. The S400-A4 designation indicates specific binning or packaging parameters within the product line. It serves as a standard discrete indicator component in the broader family of through-hole LEDs offered by the manufacturer.

Replacement Considerations

Direct substitutes must match the 3.0 mm T-1 size, green color, and diffused lens type. Verify equivalent electrical ratings for forward voltage and luminous intensity. Check mechanical compatibility with existing PCB footprints.
