CMD17-21VRD/TR8

LED Indication - Discrete Overview

The CMD17-21VRD/TR8 is a single-color red light-emitting diode manufactured by Visual Communications Company - VCC. It utilizes surface-mount technology in an 0805 (2012 metric) package with dimensions of 2.00 mm length, 1.25 mm width, and a maximum height of 1.20 mm. The component emits red light at a peak wavelength of 640 nm with a diffused lens appearance. Key electrical parameters include a typical forward voltage of 2 V and a test current of 20 mA. The device offers a luminous intensity of 6 mcd and features a viewing angle of 140 degrees. It operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

LED Indication - Discrete Procurement Notes

Verify the specific suffix TR8 corresponds to the required tape-and-reel packaging format before ordering. Confirm that the 0805 footprint matches the target PCB layout dimensions. Ensure the 640 nm wavelength meets the optical requirements for the intended application environment. Check for any regional distribution restrictions or availability constraints associated with this specific manufacturer part number.

LED Indication - Discrete Selection Notes

Select this component when a standard red indicator with moderate brightness is required in a space-constrained area. The 140-degree viewing angle makes it suitable for applications requiring broad visibility from various positions. Consider the 2 V forward voltage drop when designing the driving circuitry to ensure proper current limiting. Verify compatibility with the manufacturing process regarding moisture sensitivity level and reflow soldering profiles.

LED Indication - Discrete Part Context

This part belongs to the CMD17-21 series of single-color LEDs from Visual Communications Company. The series includes variants in different colors such as green and yellow, sharing similar physical dimensions and mounting characteristics. The TR8 suffix typically denotes the reel packaging method used for high-volume surface-mount production lines. This series is designed for general-purpose indication tasks where reliability and consistent optical performance are prioritized.

LED Indication - Discrete Replacement Considerations

Direct substitutes within the same series include CMD17-21SRC/TR8 for red diffused variants and CMD17-21VGC/TR8 for green clear options. Cross-brand replacements require matching the 0805 footprint, 20 mA current rating, and 640 nm wavelength specifications. Verify that alternative components meet the same thermal and mechanical stress requirements.
