You may have to search with different segments of your transistor part markings before you get a result.Tips to effectively search for an ID on your original part online: Some markings can indicate other things such as date codes, or some smaller parts may have encoded markings that aren’t easily searchable. Typically the production status and ID on your transistor can be found by searching for the markings online, however please note not all markings on the part will be relevant to a part number. Parts similar to the above transistor can be found by typing “bc547” into the Digi-Key search bar, or by typing in “bc547 transistor” in a search engine. Transistors typically come with full or partial type numbers printed on the body of the part. Identify Transistor Type Based on Markings

Here are the general steps taken to help to determine potential alternatives: This guide will help break down the steps we commonly take when looking for alternatives and which important parameters to use to help find the best options for a suitable replacement. Use the G0 library and symbols for the G0 model and the G2 library and symbols for the G2 model.We often get inquiries from customers looking for replacements on a variety of transistors - some of which aren’t available in our inventory due to obsolescence or a variety of other reasons. RevX are revision numbers, rev1, rev2, etc.
