APHB1608QBDSYKC

Overview

The APHB1608QBDSYKC is a dual-chip bi-color surface-mount LED from Kingbright, housed in a standard 0603 (1.6mm x 0.8mm) rectangular package with a water-clear lens. It integrates blue and red emitters to produce distinct or combined colors. The component operates at a forward current of 20 mA per chip, with typical forward voltages of 3.3 V for the blue segment and 2.1 V for the red segment. It delivers luminous intensities of 90 mcd for blue and 230 mcd for red, emitting at peak wavelengths of 470 nm and 630 nm respectively. The device supports a wide operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-chip configuration enabling independent control of blue and red light sources within a single compact footprint.
• Water-clear rectangular lens design provides high transparency and consistent color rendering.
• Robust construction suitable for dense system designs requiring improved material durability.

Applications

• Status indication for electronic devices requiring multi-state signaling
• Backlighting applications for displays and user interfaces
• Indicator lights for consumer electronics and appliances

Procurement Notes

Verify the exact suffix against official Kingbright documentation to confirm optical parameters, as variations exist within the APHB1608 series. Ensure compatibility with standard SMD reflow soldering profiles and observe moisture sensitivity levels during storage and handling. Confirm that the specific binning requirements for wavelength and intensity meet the target application standards before finalizing procurement orders.

Selection Notes

Select this component when space-constrained designs require two distinct indicator colors in a single 0603 package. It is appropriate for applications needing separate blue and red outputs rather than mixed white or amber tones. Consider the specific forward voltage differences between chips when designing the driving circuitry to ensure proper current limiting for each segment.

Part Context

This part belongs to the APHB1608 family of second-generation SMD LEDs from Kingbright. This generation offers enhanced electrical reliability and material durability compared to previous iterations. The series is designed for automated assembly processes, providing a standardized form factor widely used in modern printed circuit board layouts for compact electronic equipment.

Replacement Considerations

Direct substitutes include other Kingbright 0603 bi-color LEDs such as APHB1608QBC/D for single-color blue applications, though functional equivalence requires matching the dual-chip architecture. Cross-manufacturer replacements must be evaluated based on pinout compatibility, thermal characteristics, and optical intensity specifications.
