Parts Circuit is a leader among independent distributors of industrial automation parts and components. We are owned and operated by ASAP Semiconductor and thus have access to an inventory of more than two billion new and obsolete parts from top manufacturers including Jandorf, Jb Fittings, Jec, Jmf Company, Johnson Controls and many others.

At Parts Circuit, we only do business with top manufacturers, so customers can buy with the peace of mind that any parts we sell will function reliably for the entirety of their intended service life. We are also an AS9120B, ISO 9001:2015, and FAA AC 00-56B accredited business, as well as the only independent distributor with a strict no China sourcing policy, ensuring each part we offer comes with a full trace or is directly from its manufacturer. Parts procurement has never been easier than it is with Parts Circuit. Our mission is not only to improve the purchasing experience, but to revolutionize it entirely.
