Electronic – FFC Connector Identification

connectorffcidentification

I need to design an FPC to couple to an existing board. There are 3 FFC connections on this board. I believe them all to be Molex connectors but I still can't locate a similar part. Here is what I know:

  1. The locking tab labeled 'A3' on one end and 'KK1' on the other. The pitch is .5mm. There are 17 positions and they face up when inserted into the connector. There are tabs on each side of the FFC measuring .05" in width and .07" in length. The thickness of the stiffener is roughly .012".
  2. The locking tab labeled 'A5' on one end and 'MXJ' on the other. The pitch is .3mm. There are 31 positions and they face down when inserted into the connector.There are no ears/tabs on the mating FFC. The thickness of the stiffener is roughly .009"
  3. The locking tab labeled 'A7' on one end and 'MXJ' on the other. The pitch is .3mm. There are 21 positions and they face down when inserted into the connector. The thickness of the stiffener is roughly .006".

Unfortunately I don't have access to anything more than a camera phone at the moment so I don't have any quality pictures to provide. I am hoping the information above is enough for someone familiar with these parts, but I will add images as soon as possible.

I have located several Molex FFC connectors that look similar but nothing that looks identical. I am not sure that it REALLY matters that I find the same exact part as it's not the connector I am after but the recommended FFC layout and stiffener size.

Suggestions?

EDIT #2 ( found item #2 non-stock from HIROSE ) I used to distribute alternate connectors in volume by matched parts from my company factory direct in few weeks. MOQ 500$

You may consider;

  2. 32p 0.3mm pitch 0.2mm th. down & no ears ==> HIROSE FH26-21S-0.3SHW(?) many options (?) different MOQ 300~3000 http://www.hirose.co.jp/cataloge_hp/e58302093.pdf

  3. 21p 0.3mm pitch 0.15mm th. down, no ears,straight ====> JAE FB6S021JA1 http://jae-connector.com/en/pdf/SJ102078.pdf
