Key Features
- 6-position dual-row socket at 0.050" (1.27 mm) pitch with polarization feature prevents incorrect mating in high-density SMT assemblies
- Tin (Sn) over nickel (Ni) barrier contact finish delivers reliable electrical contact and corrosion resistance across thousands of mating cycles
- High-reliability surface mount socket strip construction withstands demanding mechanical shock and vibration in board-to-board mezzanine applications
Applications
The SFM-103-L2-L-D-A provides reliable board-to-board mezzanine connections in compact embedded systems, industrial control modules, and high-reliability instrumentation requiring 6-position 0.050" pitch SMT sockets. Its polarized design ensures correct orientation during assembly, preventing damage in automated production environments. The dual-row format efficiently routes 6 signals in a minimal PCB footprint suitable for space-constrained applications.

Frequently Asked Questions
What contact finish does SFM-103-L2-L-D-A use and how does it enhance reliability?
The SFM-103-L2-L-D-A uses a tin (Sn) plating over a nickel (Ni) diffusion barrier on its contacts. The nickel barrier prevents tin whisker migration and copper diffusion, maintaining low contact resistance over 500 or more mating cycles. This finish is compatible with standard SAC lead-free solder reflow at approximately 250°C peak temperature.
How does the polarization feature of SFM-103-L2-L-D-A benefit production assembly?
The polarized body of the SFM-103-L2-L-D-A physically prevents incorrect mating orientation during both manual and automated assembly. In a 6-position dual-row connector at 0.050" pitch, reversed insertion could damage fine-pitch contacts or short adjacent signal pins. Polarization eliminates this risk, reducing defect rates and rework costs on high-volume SMT lines.
In which high-density applications would a designer select SFM-103-L2-L-D-A over a 0.100" pitch alternative?
Designers choose the SFM-103-L2-L-D-A's 0.050" (1.27 mm) pitch over 0.100" (2.54 mm) alternatives when PCB area must be minimized by approximately 50% per signal. Typical applications include stacked daughtercard modules in portable medical devices, small-form-factor SBCs with 6 inter-board signals, and compact avionics modules where board real estate is strictly limited.
