Digi-Key is widely recognized as a leading supplier for small-scale electrical components in North America, but there are several alternatives worth considering, such as Mouser, Allied Electronics, Newark, JameCo, and FutureLec. Users express a desire for better web interfaces for these suppliers, noting that McMaster-Carr's interface is highly regarded. For specific components, resources like findchips.com and tedss.com are recommended for their comprehensive search capabilities. Radioshack's relevance has diminished, particularly in Canada, where The Source has shifted away from hobbyist components. Overall, while Digi-Key is a primary choice, other suppliers and resources can effectively meet various needs.
