Frequently Asked Questions
What is the contact pitch of the SFM-109-L2-S-D and how does it affect board layout density?
The SFM-109-L2-S-D uses a 0.050 inch (1.27 mm) pitch in a dual-row configuration, giving 18 positions across a body length of 0.605 inch. This tight pitch allows high-density interconnects on space-constrained PCBs while maintaining reliable gold-over-nickel contact integrity.
Which PCB assembly processes are compatible with the SFM-109-L2-S-D termination style?
The SFM-109-L2-S-D is designed for surface mount (SMT) assembly and is compatible with standard reflow soldering processes. Its termination finish is tin with a nickel barrier, which withstands typical reflow peak temperatures and ensures robust solder joint formation on standard FR-4 boards.
When would an engineer choose the SFM-109-L2-S-D over a through-hole dual-row socket of equivalent pin count?
Engineers choose the SFM-109-L2-S-D when board thickness constraints or double-sided SMT assembly make through-hole sockets impractical. The SMT footprint eliminates drilled holes and reduces board real estate versus a 0.100 inch pitch through-hole 18-position socket, which is critical in dense industrial and embedded designs.
