C4SMR-GJY-CU24Q7D1

Overview

The C4SMR-GJY-CU24Q7D1 is a single-color green LED from the Cree Screen Master family, designed for through-hole mounting. It features an oval dome lens measuring 3.9 mm by 3.0 mm with a height of approximately 4 mm. The component emits emerald green light at a peak wavelength of 530 nm to 540 nm. Typical forward voltage is 2.9 V at a forward current of 10 mA to 35 mA. Optical intensity ranges from 1672 mcd to 2781 mcd. It operates within a temperature range of -40°C to +95°C or +105°C depending on specific variant ratings.

Feature Summary

• Features an oval dome lens design for distinct visual indication
• Provides high brightness output in emerald green spectrum
• Supports standard through-hole radial PCB mounting

Applications

• Panel indicator lights
• Status signaling in electronic equipment
• Control interface illumination

Procurement Notes

Verify exact optical intensity and thermal limits against the official datasheet, as values vary between 1672-2781 mcd and operating temperatures up to 95°C or 105°C. Confirm package availability as distribution status may change. Ensure forward current requirements align with circuit design before ordering.

Selection Notes

Select this component when a compact 4mm oval form factor is required for green indication. Compare intensity ratings (mcd) against visibility needs. Verify that the 2.9V forward voltage drop fits the drive circuit constraints. Check if the higher temperature rating variants are necessary for harsh environments.

Part Context

This part belongs to the Cree Screen Master series, which focuses on high-brightness discrete LEDs. The C4SMR designation indicates a 4mm oval shape. It serves as a reliable indicator solution within the broader Cree LED portfolio, offering consistent color performance and mechanical durability for industrial applications.

Replacement Considerations

Direct substitutes include other Cree 4mm oval green LEDs such as C4SMN series variants. Cross-reference lens dimensions and electrical characteristics carefully. Generic replacements must match the 3.9x3.0mm footprint and through-hole lead configuration.
