| Please help with an equivalent IC for this burnt model in a PSU |

| highcap:
The machine I'm trying to restore is quite unique, and after cleaning this PSU I noticed that failed IC. As I can't find that exact model on sale, can someone help with getting an available equivalent? Thank you! H11A V2A 9434 |

It's a H11AV2A optocoupler. I have a big doubt that smoke came out of this part rather than something else. And if it's really failed explosively like this, it did not happen by itself and something else caused it instead. |

Pin #3 is not connected. https://www.farnell.com/datasheets/172176.pdf |

That's some bad news then... This means this optocoupler can never fail by itself? |
