For applications that see frequent cable swaps — test fixtures or field-replaceable modules — a gold-plated sibling is a better fit. The solder retention feature helps keep the connector in place during wave or reflow — no separate board lock needed for most applications. ## Cable Compatibility and Termination — FFC/FPC Thickness Window Accepts FFC or FPC with a thickness of 0.30 mm or 0.33 mm — the two common standard thicknesses for 1.00 mm pitch cables. The top-contact configuration means the cable's conductive pads face upward when the connector is mounted; the ZIF mechanism requires no insertion force, so the cable pads are not scraped on entry. The slide lock pushes the actuator forward to clamp the cable; a distinct click confirms full engagement. Termination is solder — the right-angle SMT pads are on a single row, which makes hand-solder inspection straightforward under magnification. The tape-and-reel packaging (available in cut tape as well) feeds into standard pick-and-place for volume assembly. ## Peer Comparison — 12-Position Top vs Bottom Contact The closest sibling is the SFW12R-1STE9LF, which shares the same 12 positions, 1.00 mm pitch, 2.70 mm height, and tin finish — but uses bottom-contact configuration instead of top. The difference matters for cable routing: top-contact connectors let the FPC fold over the top of the connector, while bottom-contact routes the cable underneath. If your PCB layout has components or keep-out zones on one side of the connector, the contact orientation determines which cable bend direction fits. The SFW12R-2STE1LF (top contact) is the more common choice for board-edge ribbon exits where the cable runs away from the board surface. For a different position count, the SFW11R-2STE1LF (11 positions) and SFW14R-2STE1LF (14 positions) are direct pitch-and-height matches with the same top-contact ZIF design — only the circuit count changes. No pinout or footprint cross-compatibility beyond the same series.","metaTitle":"SFW12R-2STE1LF — Amphenol ICC FFC/FPC Connector, 12 Pos","metaDescription":"Amphenol ICC SFW12R-2STE1LF: 12-position, 1.00 mm pitch FFC/FPC connector, ZIF slide-lock, right-angle SMT, tin contacts, 1 A, 100 V, -55°C to 105°C, UL94 V-0","metaKeywords":null},"attributes":{"series":"SFW-R","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["FFC / FPC & Ribbon Connectors","FFC / FPC Cable Assemblies"],"specifications":{"Mfr":"Amphenol ICC (FCI)","Pitch":"0.039\\\" (1.00mm)","Series":"SFW-R","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Solder Retention, Zero Insertion Force (ZIF)","Termination":"Solder","Housing Color":"Brown","Mating Cycles":"20","Mounting Type":"Surface Mount, Right Angle","Actuator Color":"Black","Cable End Type":"Straight, Tapered","Contact Finish":"Tin","Flat Flex Type":"FFC, FPC","Product Status":"Active","Voltage Rating":"100V","Locking Feature":"Slide Lock","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Housing Material":"Polyphenylene Sulfide (PPS), Glass Filled","Actuator Material":"Polyphenylene Sulfide (PPS), Glass Filled","FFC, FCB Thickness":"0.30mm, 0.33mm","Height Above Board":"0.106\\\" (2.70mm)","Base Product Number":"SFW12R","Number of Positions":"12","Current Rating (Amps)":"1A","Operating Temperature":"-55°C~105°C","Connector/Contact Type":"Contacts, Top","Contact Finish Thickness":"-","Material Flammability Rating":"UL94 V-0"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9900","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.99000","currency":"USD"},{"qty":10,"price":"$0.83700","currency":"USD"},{"qty":25,"price":"$0.80280","currency":"USD"},{"qty":50,"price":"$0.78560","currency":"USD"},{"qty":100,"price":"$0.75150","currency":"USD"},{"qty":250,"price":"$0.68316","currency":"USD"},{"qty":500,"price":"$0.61484","currency":"USD"},{"qty":1000,"price":"$0.54653","currency":"USD"},{"qty":2000,"price":"$0.51238","currency":"USD"},{"qty":4000,"price":"$0.49530","currency":"USD"},{"qty":6000,"price":"$0.47822","currency":"USD"},{"qty":10000,"price":"$0.45430","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9d6cc98064b984a64b93eda04198b6eb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the exact pitch of the SFW12R-2STE1LF?","answer":"0.039\" (1.00 mm).
