    As a Mechatronics engineer, I can only be thankful for having a tool like Octopart for my everyday tasks, looking for component replacements, having a lot of different filters, and exporting my components (Schematic, PCB, and 3D model) for PCB Design, I would say my favorite features are having my private BOMs and searching for components availability across different suppliers.

    Octopart.com has been my go-to source for searching for electronic/electrical parts and components for approximately 2 years+, now. I primarily use Octopart to see a list of vendors and suppliers for what I am looking for and their availability. This saves me time opposed to hopping from website to website searching for this information. I also find the ‘Similar Parts’ feature very useful in helping me locate alternate items when I cannot find the primary items I am looking for. The Datasheet feature is also very useful for me. I am still finding more useful features on the Octopart website and use it almost daily.

    I am a component engineer so every day I use Octopart. It has benefited me to look at components' stock, lead time and lifecycle status via using Nexar Excel Add-on. Mostly I like the speed of the site, site responses so quickly while I search.

    Octopart have been a great value in the design process. Knowing what’s in stock helps a lot. I’ve used octopart to retrieve symbols and footprints. It saves a lot of time. Also, the presence of datasheets is a nice feature.

    Octopart has been an exceptional tool that I use every day to source and price products. The Octopart site is always up, the content is accurate and current, and it covers a broad range of products. It has allowed me to transition seamlessly from 40 years of selling electronic devices to 4 years of buying them.
