5973121207F

LED Indication - Discrete Overview

The Dialight 5973121207F is a single-color surface-mount LED component designed for indicator applications. It emits red light with a peak wavelength of 645 nm and a typical forward voltage of 1.75 V at a test current of 10 mA. The device utilizes a 2-PLCC package configuration with a circular, flat-top lens that is colorless and transparent. Key physical dimensions include a maximum height of 2.11 mm and a footprint measuring 3.20 mm in length by 2.80 mm in width. The unit provides an optical intensity of 35.5 mcd and features a 120-degree viewing angle.

LED Indication - Discrete Procurement Notes

This specific part number is officially obsolete and no longer manufactured by Dialight. Procurement should focus on verified replacement components rather than original stock. Verify that substitute parts match the required electrical parameters, such as forward voltage and test current, to ensure circuit compatibility. Confirm mechanical fit within the existing PCB layout before finalizing any substitution decisions.

LED Indication - Discrete Selection Notes

Select this component type when a standard red indicator with a 120-degree viewing angle is required. The 2-PLCC package offers a compact form factor suitable for space-constrained designs. Ensure the application can accommodate the specified 1.75 V forward voltage drop at 10 mA. Consider alternative packages if higher mounting density or different thermal characteristics are needed for the target system.
