Choosing a substitute electronic part

What do you do if you can’t get the exact part used in a project? Part finder posed this question about the USB IR Toy: This component is hard to find from my local store: D1, Small signal diode (DO323, BAS16HT1G, Rectifier 85V/0.2A Small Signal Diode). Can I replace it for example with [this]? What are the important values? We didn’t give a particularly helpful reply, but Brian Willoughby picked up the slack with this fantastic description of how to pick a substitute part: The most important value is the DO323, a.k.a.

What I always do is hit Mouser. The actual selection process can be a little tricky. You’ll note that there is a 1N4148 in SOD-323 as part of the results. If you want to speed up the process, the Mouser part # page for the original part will update the number of similar parts Found as you check or uncheck different specifications, so you can quickly experiment with how precise you want the match.
