12-21/T3D-CP1Q2B12Y/2C

Overview

The 12-21/T3D-CP1Q2B12Y/2C is a single-color surface-mount LED manufactured by Everlight Electronics. It features a rectangular package with dimensions of 3.0mm x 1.5mm x 1.0mm and a total height of 1.0mm. The device emits pure white light with peak wavelength characteristics defined by chromaticity coordinates x=0.274 and y=0.226. It operates with a forward voltage of 3.05V and utilizes a water clear lens for optical transmission. The component is designed for SMD/SMT installation and is compatible with standard reflow soldering processes.

Feature Summary

• Compact rectangular surface-mount design enabling high packing density and reduced board space requirements
• Water clear lens configuration optimized for efficient light transmission in indicator applications
• Lead-free construction compliant with environmental standards for modern electronics manufacturing

Applications

• Dashboard backlighting in automotive systems
• Switch illumination in vehicle control panels
• Indicator lights in telecommunications equipment

Procurement Notes

Verify the specific suffix CP1Q2B12Y/2C against official Everlight documentation to confirm exact binning and chromaticity specifications. Ensure compatibility with automated placement equipment and verify that the lead-free status meets current regulatory requirements for the target market. Cross-reference part numbers carefully as variations exist within the 12-21 series.

Selection Notes

Select this component when a compact, high-density white LED is required for space-constrained designs. The 3.0x1.5mm footprint suits applications needing minimal board area while maintaining adequate luminous intensity. Consider the 3.05V forward voltage drop when designing drive circuits for low-voltage systems.

Part Context

This part belongs to Everlight's 12-21 series of chip LEDs, which are characterized by their small form factor and suitability for automated assembly. The series is widely used in consumer electronics and automotive industries where reliability and miniaturization are critical. The T3D designation typically refers to specific packaging or binning configurations within this product line.

Replacement Considerations

Direct substitutes may include other 12-21 series variants from Everlight with matching electrical parameters. Verify pinout compatibility and thermal characteristics before substitution. Alternative manufacturers offering similar 3.0x1.5mm white SMD LEDs should be evaluated based on chromaticity consistency and forward voltage tolerance.
