As a supplier we use mostly Digikey.
Here are our basic criteria which we often use to select components for our designs:
- must be available in Digikey (or Farnell)
- must be possible to buy in 1pcs quantity
- must be in stock
Then you may have a look at price, footprint, features, ....
Once you go to mass production, you can start optimizing (e.g. look for compatible replacements, look for best price between different suppliers, ....). However, for prototypes and small quantities we buy everything from one or two suppliers. The board price is a little bit higher, but it saves a lot of time.
