Manufacturer-direct pricing on authorised components
DigiKey sources parts directly from manufacturers rather than grey-market brokers, meaning you get genuine components at published trade prices without middleman markups inflating the unit cost.
Compare part specifications side by side before buying
Add multiple components to the comparison tool to view datasheet specs in a single table. Helps you pick the cheaper alternative when two microcontrollers or sensors meet your requirements but differ in price.
Filter by in-stock status to avoid backorder delays
The search results page includes an availability filter so you can exclude parts that are currently unavailable. This prevents your project from stalling while waiting for a single backordered component to ship.
Save favourites and shopping lists for repeat orders
Logged-in users can build named part lists - one for each project or prototype - and re-order the entire set with a couple of clicks. Eliminates re-searching part numbers every time you need to restock a breadboard or PCB.
Hardware wallets and crypto security devices in stock
Find secure element chips, NFC modules, and tamper-evident components used in cryptocurrency hardware wallet manufacturing. Datasheets and application notes are linked on each product page for design reference.
Cryptocurrency mining hardware components available
Browse ASIC chips, high-wattage power supplies, cooling fans, and PCB components suited for crypto mining rig builds. Filter by spec sheets to match your rig's voltage and thermal requirements before ordering.
Order from the DigiKey mobile app for iOS and Android
The app lets you scan barcodes, search part numbers, check stock levels, and place repeat orders from your phone. Particularly useful on a production floor when you need to reorder components without walking back to a desk.
Product Change Notifications for component lifecycle updates
Sign up for PCN alerts to receive warnings when manufacturers change specifications, discontinue parts, or revise datasheets. Catching these early lets you redesign or stock up before a critical component vanishes from supply.
Back-in-stock email alerts for out-of-stock parts
When a component shows zero availability, click the notify button and you'll get an email the moment inventory is replenished. Handy for hard-to-source semiconductors that sell out within hours of restocking.
Free product training modules and technical courses
DigiKey's Product Training section hosts manufacturer-led video courses covering new chips, sensors, and development boards. Engineers can stay current on component specs without paying for external training platforms.
Free online engineering design tools and calculators
Access resistor colour code calculators, Ohm's law converters, PCB trace width tools, and other reference utilities at no cost. These are built into the site and available to anyone browsing - no account required.
Request a custom quote for large-volume purchases
For production runs or high-quantity orders, submit a quote request through the site and DigiKey's team will respond with pricing tailored to your volume. This often beats the standard tiered pricing shown online.
Tiered volume pricing on bulk component orders
Unit prices drop automatically as quantity increases - the more you add to your basket, the lower the per-piece cost becomes. Price breaks are shown directly on each product page so you can see exactly where the next discount tier kicks in.
No minimum order quantity on electronic components
Buy a single resistor, one microcontroller, or any individual part without being forced to meet a bulk minimum. Useful for prototyping and small-run projects where you only need one or two units.
Free shipping on orders over £33
Standard delivery is included when your basket reaches £33 before tax. Orders below that threshold carry a small shipping fee, so consolidating parts into a single order keeps costs down.
