1254-10SYGT/S530-E2

Overview

The 1254-10SYGT/S530-E2 is a single-color LED lamp manufactured by Everlight Electronics Co Ltd. It features a yellow-green emission with a peak wavelength of 573nm and a clear lens finish. The component utilizes a 3.0mm round through-hole package design. Electrical specifications include a forward voltage of 2V and a forward current of 20mA, resulting in a maximum power dissipation of 60mW. The optical intensity is rated at 63 mcd.

Feature Summary

• Yellow-green light emission with a 573nm peak wavelength
• Clear lens configuration for unobstructed visibility
• Standard 3.0mm round through-hole form factor

Applications

• General indicator lighting
• Discrete signal indication
• Electronic equipment status display

Procurement Notes

Verify the specific suffix S530-E2 to ensure compliance with RoHS directives and lead-free manufacturing standards required for modern assembly processes. Confirm that the 3.0mm through-hole package dimensions align with existing PCB footprints before finalizing procurement orders to prevent mechanical integration issues.

Selection Notes

Select this component when a distinct yellow-green visual signal is required within standard through-hole constraints. The 20mA forward current rating ensures compatibility with common logic-level drivers without requiring additional current-limiting complexity beyond standard resistors. Consider the 63 mcd intensity sufficient for general panel visibility applications.

Part Context

This part belongs to Everlight's discrete LED indication series, specifically designed for general-purpose signaling. The 1254 prefix typically denotes the 3.0mm round lamp category. It serves as a fundamental passive optoelectronic component for displaying operational states in various electronic assemblies.

Replacement Considerations

Direct substitutes may include other 3.0mm yellow-green LEDs from different manufacturers, provided they match the 573nm wavelength, 2V forward voltage, and 20mA current requirements. Verify mechanical pin spacing and lens diameter compatibility.
