Para identificar el ánodo y el cátodo de un LED THT:
1. Patas del componente físico
  • La pata más larga es el ánodo.
  • La pata más corta es el cátodo.
2. Muesca o plano en la carcasa
  • El borde plano (o “muesca”) del difusor marca el cátodo.
  • El lado opuesto al plano es el ánodo.
3. Símbolo esquemático
  • El triángulo apunta del ánodo hacia el cátodo.
  • El lado con la línea perpendicular al vértice del triángulo es el cátodo.
4. En tu esquema “LED THT”
  • Conecta la fuente positiva al terminal A (ánodo).
  • Conecta la fuente negativa al terminal K (cátodo).
Así te aseguras de polarizar correctamente el LED.

¿A qué dimensión te refieres exactamente?
  • Diámetro del cuerpo (difusor) del LED?
  • Longitud de las patas (ánodo/cátodo)?
Si no tienes un requisito específico, podemos asumir un LED estándar de 5 mm de diámetro. ¿Te parece bien o prefieres otra medida?

Based on your project description, it seems like "K" is designated as a terminal component classified under the designator prefix "P", which often stands for a passive element, but in this context, it's used to label terminals. Given that this is part of an LED circuit and considering "K" stands for the cathode terminal of an LED, a proper replacement for "K" would not directly imply replacing it with another component, but rather ensuring you have a suitable terminal or connector that can connect to the cathode side of an LED or LED driver circuit.
If you're looking for a terminal or pin that can act as a cathode connection in electrotactic circuits or mounting, you might consider:
  • Through-Hole Terminal: Ideal for prototyping or circuits where you'd prefer to solder components onto a PCB.
  • Surface Mount Terminal: Suitable for more permanent or sleek designs, where space is a consideration and components are mounted directly to the surface of the PCB.
  • Screw Terminal: Offers an easy way to connect and disconnect your LED or its driver circuit without soldering, great for testing or adjustable installations.
Given the generic description of "K", the exact replacement or equivalent part depends on how you're planning to use this terminal in your LED project. I'm assuming you're looking for a general-purpose conductor terminal that can be easily integrated into your circuit design in Flux.
Remember, the specific choice depends on your design's requirements (e.g., current handling, mounting type, size constraints). If "K" plays a more specialized role in your design that wasn't detailed here, please provide further information so I can offer a more tailored suggestion.

Given the properties of your project focused on an LED (Light Emitting Diode) setup, Designator K represents a terminal part of the LED circuit, usually standing for the cathode terminal of the LED. The cathode is the negative terminal in this context.
For a replacement or an equivalent component for the K (cathode) terminal, any standard ground or negative terminal component that can handle the LED's operating voltage and current specifications would be suitable. Since we're dealing with a basic LED circuit based on the properties described, here are some recommendations:
  • Generic Ground Terminal: Almost any ground terminal from typical component libraries should suffice, as the primary requirement is a connection to the circuit's negative side or ground.
  • PCB Mount Terminal Block: For applications where you might need to connect and disconnect the LED or its power supply, a PCB mount terminal block marked for the negative side can serve as a more versatile replacement. Just ensure it's rated for at least the forward voltage (1.70V) and current you plan to pass through the LED.
  • Through-hole Pin Header: If your setup is on a breadboard or you require something that allows for easy connection to jumper wires, a through-hole pin header could be marked and used as the cathode connection point.
Remember, the key aspects to consider when choosing a replacement for the K terminal (cathode) in your LED project are:
  • Voltage Rating: Must be above the LED's forward voltage (at least 1.70V in this case).
  • Current Rating: Should comfortably handle the current you expect to flow through the LED.
  • Physical Compatibility: Whether it matches your circuit's physical layout and connection needs (e.g., through-hole, surface mount, etc.).
If any of these aspects are critical or specific to your project needs, please provide more details so I can tailor the recommendation further.
