Even after a few hours Googling, I'm unable to identify this flat-flex connector, so I'm thinking it's time to turn to the community for help!

The connector in question is this guy:

Flat-flex connector without callouts

Of course, I already looked for identifying info such as brand, etc., but was only rewarded with a few generic/informational markings:

  • "43 2B" in the upper-left-hand corner (on the back retention clip of the connector)
  • "1A" in the bottom-right-hand corner

Other things I know about the connector:

  • it has 43 circuits
  • 14.25mm length
  • 3.75mm width (with retention clip closed)
  • flex cable contacts are all the same size, but staggered into two rows
  • either 0.5 or 0.3mm pitch (hard to tell, given the staggering)

Here's the same shot of the connector with magnification in each corner (I've verified these markings by viewing/lighting at other angles; not included).

Connector with callouts

Any help that anyone can offer here would be massively appreciated!

    \$\begingroup\$ DigiKey has a category for FFC connectors. If you filter for number of positions equal 43, the filter returns only 24 results. \$\endgroup\$ – Nick Alexeev Nov 18 '15 at 4:54
  • \$\begingroup\$ @NickAlexeev Yeah, I know -- I looked there and didn't think I saw it, but I'll certainly check again! Thanks for your input, either way :) \$\endgroup\$ – ksk Nov 18 '15 at 10:33
  • \$\begingroup\$ @NickAlexeev It looks like I checked Mouser but not DigiKey! For anyone wondering, it looks like the Molex Easy-On™ 503555 series may include this part! \$\endgroup\$ – ksk Nov 18 '15 at 10:43

Thanks to a comment from Nick Alexeev (above, in comments), I realized that I had managed to check Mouser, Jameco, etc. but neglected to check DigiKey (of all places).

It appears that this part is one of the Molex Easy-On™ 503555 series connectors; specifically the 5035664300. Taking a look at the datasheet, the flex side of the connector also matches the description (staggered contacts).

Thanks for taking a look, folks!
