If a part you've selected is not in stock at any of our distributors you will have to provide an equivalent substitute before you are able to place an order.
You can add a substitue part by using the Octopart search bar. Once you find a part that is equivalent and in stock add it by clicking on the plus sign. If you select multiple part substitutes CircuitHub will select one of the parts for purchase and assembly based on availability and pricing.
Alternatively you can provide your own part sourcing if you have it available.
