Frequently Asked Questions
What is PartsMine.com?
We're a small team in Idaho with a big love for useful parts. Since 2018, we've been helping businesses, inventors, fixers, and tinkerers find the stuff they need. We source good parts from real places - labs, factories, and tech closets around the U.S., give them a once-over, and ship 'em out fast from Idaho. Everything we sell is backed by us - because you're the reason we're here.
How fast is shipping?
Pretty fast. Most orders ship within one business day from Idaho—often same-day if you catch us early. We don't mess around when it comes to getting parts out the door.
What's included?
You'll get exactly what's shown in the photos: one National Semiconductor 2N2174 germanium PNP transistor in plastic package. No guesswork, no missing pieces.
Can I get more info before buying?
Absolutely. Ask away! We're generalists, and as you can see—we've got a lot of stuff. But we'll give it our best shot and get back to you with a straight answer. No runaround.
What does "Used, clean, and in excellent condition" mean?
Used, clean, and in excellent condition means this transistor was previously installed but has been carefully removed and cleaned. It shows minimal signs of use and functions perfectly for your vintage electronics projects.
