Common Electronic Component Package Types

Below is a snippet of common electronic component package types which may help identify the package type when replacing a component or when selecting a package type for new design. Components may list a specific “Supplier Device Package” name provided by the manufacturer, which falls under DigiKeys “Package / Case”. The difference is manufacturers can call their package types whatever they choose, where DigiKeys Package / Case more closely resembles industry standard.
