Part Identification

Identifying and tracking down unknown electronic components can be difficult. If you are in need of help identifying a component Digi-Key’s TechForum community is here for you. While our team of technicians and engineers are not able to identify all parts here are some pointers on what information we need to help you identify your parts:

Tech Tips

No matter what kind of work you do there are always tips and tricks that you learn over time to help you do your job better. As Engineers and Technicians we help our customers with these tips everyday with tips that range from measuring and testing to assembly and rework suggestions. All of these and more will be found here in the TechForum Tech Tips category.

Cross Reference

The TechForum Cross Reference category is for parts that Digi-Key does not sell or parts that have gone obsolete. Our Engineers and Techs have reviewed the specifications for these parts and made a recommendation for a replacement.

Part Numbering

Many of the parts sold at Digi-Key have intricate part numbers that when broken down can tell you the parts features such as voltage, capacitance, package size or even the packaging the part comes in from the manufacturer. Here in the part numbering category you will find part breakdowns from some of our most commonly asked about parts and suffixes. If you don't see the part number you have questions please feel free to ask and we will answer as soon as possible.
