Id circuit board part

Sorry, i am not sure what i should be looking for on the page you referenced. Any direction is appreciated.

I had to jump through hoops to get to the page. Sorry. They make you do this so you see all of the ads and click on the wrong datasheet initially.

Capacitance and series/parallel operation is the usual things to worry about. Here's https://www.digikey.com/products/en...t=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25 a search of thru hole crystals.

Next, I'd base the selection on size. Put a known size of something in the a picture (A ruler is great) and figure out the size that way by calibrating. Without any options you can use a coin. Those dimensions are found online.

picture length/real length = picture xtal dimension/real dimension

Solve for real dimension. If you have software to measure in Pixels. 1 pixel = 1/72 of an inch.

$20.00 micrometer, works too.
