1254-10UYD/S530-A3

Overview

The 1254-10UYD/S530-A3 is a single-color LED lamp manufactured by Everlight Electronics Co Ltd. It features a radial through-hole mounting style with a T-1 (3 mm) package. The device emits super yellow light at a wavelength of 589 nm and utilizes an AlGaInP semiconductor material. It operates with a forward voltage of approximately 2V and is designed for discrete indication applications.

Feature Summary

• Emits super yellow light at 589 nm
• Utilizes AlGaInP semiconductor technology
• Features a 3 mm round diffused lens

Applications

• Discrete electronic indication
• Panel status indicators
• General purpose signaling

Procurement Notes

Verify the specific datasheet revision and product change notification (PCN) history, such as PCN20170427-01, to ensure component consistency. Confirm that the S530-A3 suffix aligns with current environmental compliance requirements and lead finish specifications before finalizing procurement orders.

Selection Notes

Select this component when a 3 mm radial LED with super yellow output is required. Ensure the circuit design accommodates the 2V forward voltage drop. Verify that the T-1 package dimensions fit the available PCB space and that the through-hole mounting method is compatible with the assembly process.

Part Context

This part belongs to the Everlight 3.0mm Round Type LED Lamp series. It shares the standard T-1 form factor with other variants in the lineup but is distinguished by its specific super yellow color output and AlGaInP material composition, differentiating it from red or green alternatives.

Replacement Considerations

Direct substitutes include the 204-10UYD/S530-A3-L and 204-10SUGC/S400-A5, provided they meet the same electrical and mechanical specifications.
