So I recently went on a search for what I thought was a very widely available connector in the US: a JST XH SMD female header with 5 pins (S5B-XH-SM4). Looking on Digikey, only the 4 and 6 pin versions are available, and Mouser barely has any JST header products available at all. Does anyone know what's up with these products? I can get knockoffs from China pretty easily, but I'd like to buy the real thing if I can.
