Right-angle SMT orientation routes the flex parallel to the board, keeping the z-height budget to 2.70 mm above the PCB — useful for tight enclosures where a vertical connector would block airflow or interfere with a cover. ## Top-Contact Orientation and Termination This is a top-contact connector: the contact fingers are on the upper side of the connector body, so the FPC's conductive pads must face upward when inserted. A flipped flex shorts the wrong row and won't make contact with the beams — confirm the cable's contact side before assembly. Termination is kinked-pin SMT — the pins have a slight bend that provides a press-fit retention in the PCB holes during reflow, holding the connector in place while the solder paste wets. The brown housing colour is the visual identifier for this variant. ## Peer Comparison: SFW4R-2STE9LF and SFW5R-2STE1LF The closest functional sibling is SFW4R-2STE9LF: same 4 positions, same 1.00 mm pitch, same 2.70 mm height, but with a black housing and a slide lock actuator instead of the standard ZIF flip-lock. If the locking mechanism or colour coding matters for your assembly line, the 9LF is a direct swap without a board layout change. For one more signal line, SFW5R-2STE1LF adds a fifth position at the same 1.00 mm pitch, same 2.70 mm height, same kinked-pin SMT termination — the footprint grows by 1.00 mm in width. No other parametric difference.","metaTitle":"SFW4R-2STE1LF 1.00mm Pitch ZIF FFC/FPC Connector, 4-Pos, SMT","metaDescription":"Amphenol ICC (FCI) SFW4R-2STE1LF — 1.00mm pitch, 4-position, top-contact ZIF FFC/FPC connector.
