I've found coils, especially these smaller ones, to have a lot more flexibility than people think. I've replaced coils like those in a Chicago Coin Bowler with Gottlieb and Williams coils that were the same size physically but different gauge and wire length. There's leeway in both directions, so if they are reasonably close they will probably work.

However I've never tried it on coils that hold a long time (like a lock coil). They might require closer matching. It looks like this Game Over coil probably holds for long periods, so YMMV.

On the other hand their original winding didn't exactly fare too well either.
