instead of optocoupler?

[erikssonidingle]

I have a problem.
The problem is I have a circuitboard with an optocoupler that exploded, because i Wired the thing wrong, it recieved an 250V input when it should have 5V, my fault now I need to fix it.
This is the circuit: www.datasheetcatalog.org/datasheet/clare/CPC1943GS.pdf
It says "CPC1943G" on it.
The problems are two:
Firstly, this thing has exploded before, I would like a more robust alternative if there is one, I dont care if it costs more.
Secondly, I cant find the Item in sweden, so I am happy with an substitute circuit, ot does not have to be photoelectric, I dont know why it is an "optocoupler" in the first place.
I hope someone can help me, would appreciate it immensly.
Thank you.

We have no idea what kind of device we talk about?
Where is this opto located, is it an output or input and what are the two sides connected to it?

Im sorry, I dont think I know the answer to those questions, I thought the datasheet would help, well I hoped it would But didnt.
Well, thanks for trying, Ill se if I can figure more out, until then this is all I have.

here is the board, hope it helps

the device is solid state relay so it could be replaced with another model with similar ratings that matches the size.
Did you search for other models available in your area?

You know, I dont understand electronics, i just need for someone to tell me, "buy that and solder it in the board".
I triede to find a replacement but got confused by all parameters.

there are some components driving the relay, what about them, they were probably damaged too.
