Key Features
- 84-position dual-row layout at 0.050" (1.27 mm) pitch achieves twice the density of standard 0.100" pitch connectors in the same footprint
- High-reliability SMT socket design with gold-plated contacts rated for extended mating cycles in demanding environments
- Surface mount termination enables reflow-compatible assembly and eliminates through-hole drilling, saving PCB layer cost
Applications
The SFM-142-L2-S-D-A-K is used in high-density board-to-board interconnect applications within FPGA development boards, memory module sockets, and high-speed data acquisition systems where a 0.050" (1.27 mm) pitch connector delivers maximum pin count per unit length. Its 84-position dual-row SMT socket mates with SAMTEC TSM or TFM series pin headers, enabling modular daughtercard architectures in radar, communications, and test equipment platforms. Military and aerospace electronics also rely on its high-reliability construction to maintain signal integrity across thermal cycling and vibration environments.

Frequently Asked Questions
How does the 0.050" pitch of the SFM-142-L2-S-D-A-K compare to standard 0.100" connectors for high-density designs?
At 0.050" (1.27 mm) pitch, the SFM-142-L2-S-D-A-K provides twice the pin density per unit length compared to standard 0.100" (2.54 mm) connectors. Its 84 positions in a dual-row SMT layout allow designers to route more signals across a shorter board edge, which is critical in space-constrained FPGA boards, radar modules, and test instruments where connector footprint directly impacts PCB size.
What mating connectors are compatible with the SAMTEC SFM-142-L2-S-D-A-K socket strip?
The SFM-142-L2-S-D-A-K is designed to mate with SAMTEC TSM and TFM series 0.050" pitch dual-row pin headers, which are available in through-hole and surface mount variants. The gold-plated socket contacts maintain reliable electrical continuity with mating pins over hundreds of insertion cycles, making this combination suitable for removable daughtercard configurations requiring 84 signal paths at 1.27 mm pitch.
Is the SFM-142-L2-S-D-A-K suitable for military or aerospace applications with strict reliability requirements?
Yes, the SFM-142-L2-S-D-A-K is a high-reliability SAMTEC socket strip with gold-plated contacts and a robust SMT construction that withstands thermal cycling from -55°C to +125°C and mechanical vibration typical of military and aerospace environments. Its 84-position dual-row design at 0.050" pitch meets the density requirements of avionics backplanes and rugged instrumentation while maintaining low contact resistance across extended service life.
Can the SFM-142-L2-S-D-A-K be assembled using standard SMT reflow processes?
Yes, the SFM-142-L2-S-D-A-K features SMT termination compatible with standard lead-free reflow soldering at up to 260°C peak temperature. Its surface mount footprint is designed for automated pick-and-place equipment, supporting high-volume PCB manufacturing without the additional drilling and wave-soldering steps required for through-hole 84-pin socket alternatives.
