Key Features
- 10-position dual-row 0.050-inch pitch socket with split board lock for secure PCB retention during mating and unmating operations
- Tiger Eye contact technology with tin-over-nickel finish delivering gas-tight, low-resistance connections in compact surface mount footprint
- Split board lock mechanical feature prevents connector walking during insertion forces, improving assembly yield in automated PCB production
Applications
The SFM-105-02-L-D-LC is used in compact mezzanine and daughter-card stacking designs where a low-profile 10-position dual-row connector is required. Its split board lock feature makes it well-suited for portable instrumentation and medical device boards where mechanical stability during use is critical. The 0.050-inch pitch socket strip is also common in FPGA expansion modules and wireless communication subsystems requiring dense, space-efficient interconnections.

Frequently Asked Questions
What mechanical retention feature does the SFM-105-02-L-D-LC include, and how does it benefit PCB assembly?
The SFM-105-02-L-D-LC includes a split board lock feature that anchors the connector body to the PCB through dual locking pegs. This prevents the connector from shifting or walking during mate and unmate operations, reducing solder joint stress. In automated PCB assembly using reflow soldering at up to 260°C, the split board lock maintains connector alignment and improves long-term mechanical reliability.
What contact finish does the SFM-105-02-L-D-LC use, and is it compatible with lead-free soldering processes?
The SFM-105-02-L-D-LC uses tin-over-nickel contact finish on all 10 positions. This finish is compatible with RoHS-compliant lead-free soldering processes, and the connector body meets requirements for standard reflow profiles peaking at 260°C. The tin-over-nickel finish provides good corrosion resistance in typical industrial and commercial operating environments with humidity up to 85% RH.
For a 10-pin dual-row compact interconnect design, when should SFM-105-02-L-D-LC be chosen over a single-row alternative?
The SFM-105-02-L-D-LC dual-row layout at 0.050-inch pitch packs 10 positions in roughly half the PCB length of a 10-position single-row connector at the same pitch. Choose the dual-row SFM-105 when the PCB length budget along the connector axis is under 0.280 inch, or when you need matched differential pairs routed symmetrically across both rows. Single-row alternatives are preferred only when row separation is unacceptable for signal integrity reasons.
What is the factory lead time for SFM-105-02-L-D-LC, and is it stocked by major distributors for immediate delivery?
The SFM-105-02-L-D-LC has a factory lead time of 1 week, which is among the shortest in the SAMTEC SFM product family. This short lead time reflects active production status and regular distributor restocking. Many authorized distributors carry stock of this 10-position dual-row socket strip for same-day or next-day shipment, making it a low-risk component for prototyping and production builds.
