AAA3528ESGCT

Overview

The AAA3528ESGCT is a surface mount bi-color LED lamp manufactured by Kingbright, housed in a 1411 (3.5 x 2.8 mm) package with a height of 1.9 mm. It features separate red and green light sources on a single component. The red element utilizes Gallium Arsenide Phosphide on Gallium Phosphide substrate, while the green element uses Gallium Phosphide. The device includes a water clear lens with a round flat shape and a viewing angle of 120 degrees. It supports standard SMD assembly processes and is supplied on tape and reel.

Feature Summary

• Dual independent control for red and green elements within a single compact package
• Water clear lens design providing a wide 120-degree viewing angle
• Compatibility with standard SMD assembly and soldering processes
• RoHS compliant construction suitable for moisture sensitivity level 3

Applications

• Circuit board status indicators requiring dual-state signaling
• Electronic equipment front panel displays
• Consumer appliance control interfaces
• Industrial equipment signal lamps

Procurement Notes

Verify the specific suffix configuration to ensure correct color combination and binning requirements. Confirm moisture sensitivity handling procedures during storage and reflow soldering. Check RoHS compliance documentation against current regulatory standards. Validate thermal management capabilities for the intended operating environment. Ensure packaging specifications match automated placement equipment requirements.

Selection Notes

Select this component when space constraints require a dual-color indicator in a standard 3528 footprint. Consider the separate electrical control requirements for each chip during circuit design. Evaluate the forward voltage differences between the red and green elements for driver compatibility. Assess the luminous intensity requirements against the available output levels. Verify mechanical clearance for the 1.9 mm component height.

Part Context

This part belongs to Kingbright's surface mount LED lamp series, designed for high-density PCB applications. The 3528 form factor allows for compact designs in modern electronics. The manufacturer specializes in LED components for automotive, industrial, and consumer markets. This specific model integrates distinct semiconductor materials for optimal color rendering.

Replacement Considerations

Direct substitutes include other 3528 bi-color LEDs from Kingbright such as the AAA3528SURKCGKCT or AAA3528AVU/SURKCGKCT. Cross-manufacturer replacements must match the 3.5 x 2.8 mm dimensions and pin configuration. Verify spectral characteristics and forward voltage parameters before substitution.
