It's about 14mm wide and has 21 pins.

  • \$\begingroup\$ The pitch (distance between center of of pin) is more important than the size of the connector itself. \$\endgroup\$ – Bort Jan 31 at 1:45

    \$\begingroup\$ It looks like it's 1mm between pins on the same row. \$\endgroup\$ – ShawnM Jan 31 at 2:01
  • \$\begingroup\$ Given you probably want to replace this, check the other side for damage as well... \$\endgroup\$ – Natsu Kage Jan 31 at 4:01

This is called a mezzanine connector. It interconnects directly two PCBs together. They are meant to provide "a mechanically secure, high density electrical interface between parallel printed circuit boards."

This specific connector is the 91930-21121LF, of the Conan/MezzSelect Series by Amphenol.

From Jasen's comment and datasheet:

datasheet note 7 "the three slots may be located at either end"

  • \$\begingroup\$ yeah, something the mirrior image of that \$\endgroup\$ – Jasen Jan 31 at 3:54

    \$\begingroup\$ datasheet note 7 "the three slots may be located at either end" so yeah that or a different height versiopn of that. cdn.amphenol-icc.com/media/wysiwyg/files/drawing/91900.pdf \$\endgroup\$ – Jasen Jan 31 at 3:59
  • \$\begingroup\$ Wonder why exactly those three slots are at either end... Probably a by product of the molding? \$\endgroup\$ – Natsu Kage Jan 31 at 4:01
  • \$\begingroup\$ As a suggestion, How i search?.. I googled - 21pin, surface mount PCB connector -and scrolled through images \$\endgroup\$ – User323693 Jan 31 at 4:33
  • \$\begingroup\$ Thank you for help. \$\endgroup\$ – ShawnM Jan 31 at 20:04

the name of that connector should be "DIP pin connector" with 21p. check the length between the pin if the length between the pin (pitch) 1.27mm so your DIP connector is DIP female 1.27mm pitch 21p you can check either online or in Mouser.com

or i could be wrong but that's not like dip connector at all.. you could check the cable (male version) for making sure, it's usually have code either in female or male housing.
