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: LM393M dual comparator in 8-pin SOIC package, no additional parts. 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 "Unused, New Old Stock" mean?
