Equivalent
PS2502-1-A is a Sharp 1-channel optocoupler with a phototransistor output. Direct cross-references depend on CTR and pinout, but common equivalents from other brands include: Everlight EL817 (EL817C), Lite-On LTV-817, Vishay ILD213/ILD214, and the generic 4N25/4N26 family. Always verify CTR, input forward current, Vce, and pinout in the datasheet to ensure a valid swap.
Pinout
PS2502-1-A is a 4-pin, single‑channel phototransistor optocoupler. Function: it provides electrical isolation by using an input LED (optical emitter) to drive an output phototransistor, enabling signal transfer and level shifting while isolating input and output circuits. Typical pin assignment (verify with the manufacturer datasheet for package orientation):
- Pin 1: LED Anode
- Pin 2: LED Cathode
- Pin 3: Transistor Emitter
- Pin 4: Transistor Collector
Always confirm exact pin numbering and package drawing from the official datasheet before use.
