The part was easy to install, functioned properly right away, and seems to be good quality. Great to have a reliable replacement at a reasonable price. ### ⭐⭐⭐⭐⭐ Great transisters at great price. *by F***O on May 7, 2026* Transistors worked perfectly in circuit I bought them for. Great price. ### ⭐⭐⭐⭐⭐ A lifesaver for board repairs *by F***L on April 19, 2026* Exactly what I needed to get my project back on track. I accidentally fried a transistor while testing voltage by touching two points together, but this chip made for a quick and easy swap. I pulled the bad one out and slid this one into the slots easily. The board fired right back up and has been working perfectly ever since. If you need a reliable replacement for a damaged Darlington transistor, this part does the job exactly as expected.
