Can anyone identify the series of connector used for the AC input of this TDK MSA818 PSU from the late '80s?

The pin spacing is ~7.3mm (3.65mm if you count the missing pins) which doesn't match any JST series that I know of. The pin size is ~1.1mm.

I'll be replacing it with a Meanwell RPT-60C, which uses a JST VH connector with 3.96mm spacing.

  • \$\begingroup\$ JST have a lot of those type connectors but they are 3.96-mm-pitch. If you are interested, you can check them from here. \$\endgroup\$ – Rohat Kılıç May 2 at 12:46
  • \$\begingroup\$ @RohatKılıç yes, I already mention the JST VH range in the question. \$\endgroup\$ – Alnitak May 2 at 14:27

Looks like HWS1884 on this site https://www.peconnectors.com/friction-lock-hdrs-housings-page-4/

Or maybe these

Scroll down to Associated Products for the female pins to crimp on to the wires.

    \$\begingroup\$ thanks, but 0.156" (3.96mm) is not 3.65mm \$\endgroup\$ – Alnitak May 2 at 14:27
  • \$\begingroup\$ Let us know how you make out. I'm not finding any 3.65mm pitch connectors, doesn't seem to be anyone's standard size. Can you pop the pins out of the housing and crimp new pins onto whatever you're going to use? \$\endgroup\$ – CrossRoads May 2 at 17:11
  • \$\begingroup\$ that's a possibility, yes, the female pins on the existing connector are slightly larger than the male pins on a JST VH plug, but hopefully not so large that they won't actually fit in the VH housing. \$\endgroup\$ – Alnitak May 2 at 23:00
