@Supernoodle2014, A copy of a device originally made by one manufacturer that is made by another "me too" manufacturer _should_ be the same as the original but there can be several reasons why they may differ either slightly or widely. The reasons can vary from differences in the foundry in which they are made to simple fraud on the part of the "me too" supplier. Unless you physically check the parts yourself (or use a 3rd party test house), you have to trust that the copy is not a fake. Since you can trust parts from LCSC because they are a reputable supplier, the only way to be sure is to compare the manufacturer's datasheets in detail: [http://www.mccsemi.com/up_pdf/SK32-SK310(DO-214AB).PDF](http://www.mccsemi.com/up_pdf/SK32-SK310%28DO-214AB%29.PDF) [https://datasheet.lcsc.com/szlcsc/SK34WA_C122863.pdf](https://datasheet.lcsc.com/szlcsc/SK34WA_C122863.pdf) (I looked for a datasheet for the SK34WA part on the Shike website but it is either not available or their search tool is broken... as is much of the rest of their site.)

Thanks, I'll see if I can find a more in-depth datasheet from Shike.

The datasheet on the LCSC page is from Shike. There's no date on it but it's probably about as good as you'll get.
