5977721207LCF is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists Dialight. Its product description is LED Y/G PLCC-4 SMD 7" REEL. Review the specifications below when checking this part for your BOM.
The Dialight 5977721207LCF is a surface-mount LED indicator in a 4-PLCC package. It features a yellow-green lens with a colorless, clear finish. The component emits light at a peak wavelength of 585nm and a main wavelength of 590nm. Typical forward voltage is 1.8V at a test current of 20mA. It provides an intensity of 16mcd with a 120° viewing angle. Dimensions are 3.10mm length, 2.80mm width, and 2.05mm maximum height.
Verify RoHS3 compliance and REACH status before integration. Confirm moisture sensitivity level (MSL 2) handling requirements during storage and reflow soldering processes. Ensure the specific LCF suffix matches the reel packaging configuration required for the manufacturing line.
Select this component when a compact, high-brightness yellow-green indicator is required. The 120-degree viewing angle offers broad visibility. Verify that the 1.8V forward voltage aligns with the driving circuit's output capabilities and current limiting resistors.
This part belongs to the microLED series by Dialight. It serves as a discrete indicator solution within the broader portfolio of surface-mount LEDs. The 4-PLCC form factor is widely used in consumer electronics and industrial control boards for space-constrained applications.
The 5977721202F is listed as a discontinued alternative. Direct substitution requires verification of electrical parameters and mechanical fit against the original design specifications.
