Frequently Asked Questions
What position count and pitch does the SFM-144-T2-F-D-A-K socket strip offer for high-density board connections?
The SFM-144-T2-F-D-A-K provides 88 total positions in a dual-row configuration (44 per row) at a 1.27 mm (0.050") pitch. This combination allows 88 independent signal or power connections in a compact surface mount footprint, supporting high-density mezzanine and daughter card designs in telecom and industrial computing systems.
For a removable FPGA daughter card design with 80+ signal pins, how does the SFM-144-T2-F-D-A-K support repeated insertion cycles?
The SFM-144-T2-F-D-A-K uses gold-plated (A suffix) contacts designed for high-reliability repeated mating. Gold plating maintains low and stable contact resistance over many hundreds of insertion cycles, which is critical for removable FPGA daughter cards that may be swapped during development and field maintenance. The 88-position dual-row socket comfortably accommodates 80+ FPGA I/O signals at the compact 1.27 mm pitch.
Which mating terminal strip connectors from SAMTEC are compatible with the SFM-144-T2-F-D-A-K at 1.27 mm pitch?
The SFM-144-T2-F-D-A-K mates with SAMTEC's TSM and TFM series terminal strips designed for 1.27 mm (0.050") pitch dual-row layouts. Compatible TFM or TSM mating headers are available in 88-pin dual-row configurations with various stacking heights (typically 4 mm to 20 mm), enabling flexible board-to-board separation in stacked PCB assemblies.
