C4SMK-GJF-CW14Q7C1

Overview

The C4SMK-GJF-CW14Q7C1 is a discontinued single-color green LED from the Screen Master series by Cree LED. It features a radial through-hole T-1 3/4 (5 mm) oval dome lens with dimensions of 3.90 mm x 3.00 mm and a maximum height of 10.50 mm. The component emits light at a peak wavelength of 527 nm with a typical forward voltage of 3.4 V at a test current of 20 mA. It delivers a luminous intensity of 4010 mcd and has a power rating of 140 mW. The lens is clear, and the device complies with RoHS3 standards.

Feature Summary

• High-intensity green emission optimized for visibility in indicator applications
• Standardized T-1 3/4 radial lead frame construction for reliable through-hole mounting
• Clear oval dome lens design providing wide viewing angles

Applications

• Panel status indicators
• Control board visual signaling
• Equipment front-panel displays

Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Cree LED. Procurement must focus on verified replacement components rather than original stock. Verify that substitute LEDs match the required electrical parameters, specifically the 3.4 V forward voltage and 20 mA operating current, to ensure circuit compatibility. Confirm mechanical fit within existing PCB layouts due to potential dimensional variances in alternatives.

Selection Notes

Designers should prioritize components with identical radial lead spacing and T-1 3/4 package dimensions to maintain board integrity. Ensure the replacement maintains the 527 nm peak wavelength for color consistency. Evaluate luminous intensity requirements against available substitutes, as intensities may vary. Check for RoHS3 compliance in new selections to meet environmental regulations. Validate thermal performance under continuous operation conditions.

Part Context

The C4SMK belongs to the Screen Master family of high-brightness LEDs designed for general indication purposes. This series utilizes advanced semiconductor materials to achieve superior brightness compared to standard LEDs. The radial configuration allows for easy insertion into printed circuit boards without requiring specialized surface-mount equipment. The product line has been largely superseded by newer generations offering improved efficiency.

Replacement Considerations

Everlight Electronics Co Ltd part 3474AN-GADB-AMNA-PR-MS is a documented similar replacement.
