Key Features
- 84-position dual-row layout on 0.050 inch (1.27 mm) pitch for high-density surface-mount board-to-board mating
- High-reliability socket strip construction engineered for repeated insertion cycles in mission-critical instrumentation and computing systems
- Surface-mount termination style enables reflow-compatible pick-and-place assembly with excellent co-planarity across all 84 contacts
Applications
The SFM-142-02-STL-D is tailored for high-density mezzanine and daughtercard socket applications in FPGA development boards, test and measurement instruments, and embedded computing platforms where 0.050 inch pitch maximizes contact count within a constrained PCB footprint. Its dual-row 84-position configuration provides 84 signal or power paths in a compact SMT body, simplifying BOM management for high-pin-count module sockets. The surface-mount design integrates cleanly into automated SMT assembly lines, reducing manual assembly cost compared to through-hole alternatives.

Frequently Asked Questions
How many positions and rows does the SFM-142-02-STL-D provide, and what pitch is used?
The SFM-142-02-STL-D offers 84 total positions arranged in 2 rows on a 0.050 inch (1.27 mm) pitch. This dual-row 0.050 inch configuration is a standard SAMTEC high-density format widely used for mezzanine sockets, FPGA expansion cards, and test fixture interfaces where maximizing contact count per unit length is critical.
Is the SFM-142-02-STL-D suitable for automated SMT assembly, and what co-planarity can be expected?
Yes, the SFM-142-02-STL-D uses a surface-mount termination style specifically engineered for pick-and-place and reflow soldering. SAMTEC designs SFM-series strips to maintain tight co-planarity across all 84 contacts, minimizing solder joint defects during SAC305 or lead-free reflow at typical peak temperatures of 245°C to 260°C. The SMT body also reduces PCB drilling costs versus through-hole socket strips.
What distinguishes the SFM series high-reliability socket strip from standard socket alternatives for repeated-mate applications?
The SFM-142-02-STL-D is built to SAMTEC high-reliability standards, meaning contacts are rated for a higher number of mating cycles than economy socket strips, typically 500 or more insertion cycles before contact resistance degrades beyond specification. For applications such as module swap-out in field-deployed instruments or ongoing development board reconfiguration, this extended cycle rating prevents premature failure at the 84-position mating interface.
