To quickly begin your search, simply type keywords into the search field on the front page and click Search. You can use the checkboxes below the search bar to ensure that the parts you search for are RoHS compliant, lead free, in stock, or contain symbol/footprint data.
Click All Categories beside the search bar to access a list of all categories. Categories with an arrow beside the name will display subcategories when clicked. Select a category/subcategory to be taken to the relevant search results page.
Narrowing Search Results
The options under Filters on the left sidebar of the search results page will help you narrow down your search and more easily find the parts you are looking for. Clicking the name of a filter brings up a menu where you can set your search parameters. After selecting the filters you want, click Done and they will be applied.
Once you start selecting filters, you may notice that the list of available search filters starts to decrease. PartQuest automatically removes any remaining filters that would bring your search results to 0. If you would like to change this, click "Show all Filters" at the top right of the Filters menu. (This has changed. Now there is only a Reset All Filters option at the bottom. That was a good feature if you still have it because my search result was 0 because additional filters were not removed.)
After clicking Done, the filters you have applied will appear in the left sidebar under Filters.
The Lead Free label indicates that the component contains no lead. If the label is absent, either the component contains lead or there is no information available pertaining to its lead content.
The RoHS Compliant label indicates that the component is compliant with the EU's Restriction of Hazardous Substances Directive. If the label is absent, either the part is not RoHS compliant or there is no information available pertaining to its RoHS compliance.

The 3D Model icon indicates that a 3D version of the part is available for download from SamacSys. It will be downloaded with the Symbol and Footprint data. 3D Models are currently available for many discrete parts.
