We developed a new feature called “Parts Reservation” to provide an answer to the volatile character of the supply chain of components.

With our Parts reservation service we offer help with the sourcing of parts that are either difficult to obtain due to shortages or have longer lead times or where no alternative exists in the market and thus are even more critical to obtain. We are happy to source these (as available) and have them available for when you are ready to place your order with us. We will ignore parts that we identify as Generic components, eC-stock parts or easily obtainable parts as these can be sourced immediately when the assembly order is placed.

Request a Part Reservation Budget

Before you can start uploading a list of parts that you want us to reserve for you, you will need to have a budget for parts reservation which is assigned by us.


This budget is the maximum amount of stock in € that we will buy and hold for you. The general idea is to keep this within limits and only reflect the component requirements for your next upcoming project.


Upload your Part List (BOM)

Drag & Drop or browse for the BOM list of components you would like us to reserve for you.


As soon as you have uploaded your Part List our software starts to analyse your data.


Edit the BOM List

You can edit or modify your BOM list at any time up until we start the sourcing process by clicking on the ‘find alternatives’ button or ‘search part’ button.

It might be necessary for you to assist our algorithms to identify a part (or parts) if the BOM file is incomplete or the MPN is not recognised.

The logic behind manipulating the BOM list is the same as is available in the BOM-editor in the PCBA Visualizer tab of our Calculate and Order interface.


Then submit your reservation request.


Your Part Reservation Request is now in process


Once all of the parts in your BOM list are identified our engineering team starts analysing the parts.
Generic parts cannot be reserved as they are normally always available.


On demand parts will be purchased by Eurocircuits and will be kept in stock especially for you


Once we approve your request for parts reservation we will begin the sourcing process and the request will be moved to the “History” section.

Within the “History” section you will see a list of all the Parts Reservation requests and their status.


Inventory Report

This gives an overview of all the individual parts you have requested to reserve for you and their availability status.


Inventory shown in Calculate and Order

If you upload a new BOM file in Calculate and Order” and it contains any of the reserved parts in your inventory the availability of these will be shown.

Eurocircuits Preferred Component Suppliers and Eurocircuits Generic Parts

You are looking for functionality when deciding on a component. But just as important are the reliability, the solderability and the delivery options of the component. The supplier of the component plays a major role in this.

Over the years Eurocircuits has established an expertise with which component suppliers do well. We have put them in a list of preferred suppliers in order of importance to us.

It can be useful to look for your components among the suppliers in this list.

Generic parts.

In order to give us maximum flexibility in finding the right and cheapest electronics parts for you, it is advisable to define as many generic parts as possible in your BOM list. You can find our list of generic resistors and capacitors here.
