Component Sourcing Channels

PCBONLINE provides you with cheap brand-new OEM electronics parts. We are able to provide cheap components because we cooperate with 300+ original component manufacturers for 10+ years, and we source at huge amounts so that the average cost is low. You can buy any active and passive components from us. Here are three sourcing channels.

  • 1. Basic normal components from our warehouse

    Our own warehouse stores basic electronic components of 300,000 to 50,000 models. Most are passive components, and our warehouse is next to our PCBA factory. If you order basic components, we can deliver them to you in no time; if you order PCBA as well, we can start PCB assembly at once.

  • 2. Special industrial and military level components from our Hongkong supply chain

    For many active components like ICs, some special components, especially those industrial and military level components, our Hong Kong supply chain buys from overseas dealers at large volume to reduce the average cost so that we can provide these special components at a reasonable price.

  • 3. Unusual electronic components custom-made at our local factories

    For unconventional hardware parts, unusual electronic components, special-shaped LEDs, and package components, we have them custom-tailored at the local trustworthy factories and then deliver them to you.

  • Note:

    All electronic components from the above channels are traceable and are of high-quality. We can also buy components from your recommended channel or accept your own components for your PCBA, but we cannot guarantee component quality in such a case. Without your literal request, we don't provide replacement parts, refurbished parts, or aftermarket parts, or inventory that are stored over one year.


Our Business Partners

  • Our PCBA factory has been run for over ten years. Over the past years, we keep long-term strategic cooperation with well-known active electronic component suppliers, such as Digi-Key, Mouser Electronics, Arrow Electronics, Avnet, etc. Compared to normal customers, we can buy active components from them at a lower price and enjoy better service, so you can buy cheaper components from us than if you buy from them on your own.
