Those jacks are not designed for sockets. The pins are irregular lengths, too thin and close together to be suitable for push-on connections. The datasheets for those parts clearly say solder terminations. Stranded wire, solder and optional heat-shrink is the proper termination.Maybe a PC mount jack is a better solution for you?
Thanks, maybe, but I'm not mounting the jacks directly to the PCB. The jacks are mounted to a panel and then wired to a PCB inside the bottom of the enclosure. I suppose I could create another PCB just for the jacks and wire that to the main board, but it seems like that would create headaches.
But thank you for adding to the growing consensus that stranded wire is the way to go. This is one of those things that always eluded me but never needed to think too much about.
