Key Features
- 16-position dual-row female socket at 0.050" (1.27 mm) pitch delivers high-density signal routing in a compact 0.555" x 0.145" SMT body
- Gold-over-nickel contact finish on mating surfaces ensures low and stable contact resistance through thousands of mating cycles
- Tin-over-nickel termination finish provides reliable solder joint formation during reflow assembly on standard PCB pads
Applications
The SFM-108-L2-S-D is designed for fine-pitch board-to-board and mezzanine socket applications in embedded computing, test and measurement, and industrial electronics requiring 16 reliable signal connections. Its gold-over-nickel contact finish makes it suitable for high-cycle daughter card applications in production test fixtures and reconfigurable computing platforms. The compact 0.555-inch body length allows placement in PCB zones with minimal connector clearance requirements.

Frequently Asked Questions
What is the body size of the SFM-108-L2-S-D and how does it influence PCB placement?
The SFM-108-L2-S-D measures 0.555 inches in length, 0.145 inches in breadth, and 0.185 inches in depth. This compact envelope allows placement of the 16-position dual-row socket in PCB zones with tight component-keep-out requirements, enabling higher-density designs than connectors with 0.100-inch pitch or larger single-row alternatives.
What contact finish does the SFM-108-L2-S-D use and why is it important for connector longevity?
The SFM-108-L2-S-D features a gold-over-nickel finish on the mating contact surfaces and tin-over-nickel on the termination tails. Gold plating on the mating interface provides corrosion resistance and maintains low contact resistance below 20 mΩ across thousands of insertion and extraction cycles, critical for test sockets and mezzanine boards that are frequently mated and unmated.
How does the SFM-108-L2-S-D dual-row 0.050-inch pitch layout help in a 16-signal mezzanine interface?
By placing 16 contacts in two rows at 0.050-inch (1.27 mm) pitch, the SFM-108-L2-S-D achieves the same 16-signal capacity in roughly half the board length of a single-row 0.100-inch pitch alternative. This dual-row arrangement is especially beneficial on mezzanine boards where the interconnect zone is restricted to a narrow strip along the daughter-card edge.
When is SFM-108-L2-S-D a better choice than a standard 2.54 mm pitch socket for a compact PCB design?
When PCB area is constrained and 16 signals must be passed across a mezzanine interface, the SFM-108-L2-S-D at 0.050-inch pitch occupies approximately 4 times less linear board space than a 2.54 mm (0.100-inch) pitch equivalent. This makes it the preferred socket when the available connector zone is less than 12 mm wide and trace routing density prohibits larger footprints.
