AA3021YS

Overview

The Kingbright AA3021YS is a single-color yellow light-emitting diode designed for surface-mount technology applications. It utilizes a PLCC-2 (1208 metric) package with an oval, water-clear lens to optimize light transmission. The component emits light at a peak wavelength of 588 nm with a luminous intensity of 15 mcd. Electrical characteristics include a forward voltage of 2.1 V and a maximum power dissipation of 75 mW. It operates within a temperature range of -40°C to +85°C and complies with RoHS standards.

Feature Summary

• Surface-mount construction in a compact PLCC-2 package suitable for automated assembly processes
• Water-clear oval lens design enhances optical efficiency and visual clarity
• Compliance with environmental regulations including RoHS certification

Applications

• General purpose indicator lighting on electronic circuit boards
• Status indication in consumer electronics devices
• Panel mount indicators for control interfaces

Procurement Notes

Verify the specific manufacturer part number AA3021YS against official Kingbright documentation to confirm current availability status. Ensure that the selected variant matches the required electrical parameters and packaging format for your production line. Cross-reference datasheet specifications for thermal management requirements during integration.

Selection Notes

Select this component when a standard yellow indicator with moderate brightness is required for space-constrained designs. Consider the 1208 footprint compatibility with existing PCB layouts. Evaluate the forward voltage drop against available drive circuits to ensure proper biasing without excessive current limiting components.

Part Context

This device belongs to the Kingbright KA-3021 series of surface-mount LEDs. The series offers various color options within the same PLCC-2 form factor, allowing designers to maintain consistent mechanical footprints while changing signal colors. The AA3021YS specifically provides the yellow emission spectrum within this standardized family.

Replacement Considerations

Direct substitutes within the same series include AA3021SYSK for higher brightness yellow output or AA3021QBS/D for blue variants. Other Kingbright PLCC-2 yellow LEDs may serve as functional replacements if pinout and dimensional tolerances align with the original design constraints.
