Key Features
- 84-position dual-row configuration on a 1.27 mm (0.050") pitch delivers high signal density in a compact SMT footprint
- High-reliability socket design with gold-plated spring contacts rated at 1 A per pin for consistent mating cycle performance
- Surface mount termination compatible with standard reflow soldering profiles for automated PCB assembly
- STL (socket, through-hole lead) contact style provides secure mechanical retention and low insertion force mating
Applications
The SFM-142-L2-STL-D-A is designed for high-density board-to-board and board-to-module interconnects in space-constrained applications such as FPGA mezzanine cards, high-speed data acquisition systems, and RF front-end modules. Its 1.27 mm pitch dual-row socket strip enables 84 signal connections in a fraction of the board area required by 2.54 mm pitch alternatives. The surface mount format and high-reliability contact design make it well suited for instrumentation, defense electronics, and compact embedded systems demanding long service life.

Frequently Asked Questions
What pitch does SFM-142-L2-STL-D-A use, and how does it compare to standard 2.54 mm pitch socket strips?
The SFM-142-L2-STL-D-A operates on a 1.27 mm (0.050 inch) pitch, which is exactly half the 2.54 mm standard. This finer pitch allows 84 dual-row contacts to fit in roughly half the board area of an equivalent 2.54 mm connector, making it a strong choice for space-constrained PCB designs where routing density is critical.
What is the current rating per pin for SFM-142-L2-STL-D-A, and how should power pins be allocated?
Each contact in the SFM-142-L2-STL-D-A is rated at approximately 1 A. For designs that need higher power delivery, engineers should assign multiple pins in parallel to a single power rail; for instance, 4 pins in parallel handle up to 4 A while leaving the remaining 80 contacts available for signal routing in mixed-signal applications.
Which high-density mezzanine or module applications benefit most from using SFM-142-L2-STL-D-A?
SFM-142-L2-STL-D-A excels in FPGA mezzanine cards, software-defined radio modules, and high-speed data acquisition boards that require 84 or more signals on a compact 1.27 mm pitch SMT footprint. Its high-reliability spring contacts withstand hundreds of mating cycles, making it equally suitable for test fixture sockets and field-replaceable module connectors in defense and instrumentation systems.
