Question of the Month: When you're choosing components for a new project, what influences your selection the most?

cstanton

Component selection is a key part of every project, but the reasons behind those choices can vary widely. We’re curious—what factors carry the most weight when you’re deciding what to use?

Bonus Question:
Can you share an example where a specific factor—like availability or documentation—completely changed what component you ended up using?

    I tend to choose components based on the following criteria - in order: What I have in stock Which component has the right features (including cost) for the application What is in my CAD library…

    Cost only comes into play after you find a selection of components that do the job.

    Detailed datasheets and documentation

    but only because it gets to veto any other consideration - if the part won't work or won't fit then it's no use.

    After that, it depends - for a quick test jig or proof of concept (both of which I do quite a lot) then availability quickly is often the primary consideration.

    For a job where I expect to make and deliver a few working prototypes then Availability from your preferred distributor is important.

    Manufacturer reputation is often a consideration, and more so when the design will eventually be built in large numbers.

    The significance of Eval boards and reference designs depends a great deal on the type of part and how different it is from similar parts that I may have used before.
