Frequently Asked Questions
How many positions and what pitch does SFM-143-T2-H-D-A-K provide for board-to-board connections?
The SFM-143-T2-H-D-A-K features 86 positions arranged in a dual-row configuration with a 0.050-inch (1.27 mm) pitch. This high pin count and tight pitch allow up to 43 signals per row, making it suitable for parallel data buses, differential pairs, and mixed signal-power interfaces on densely populated PCBs.
What mating connector from the Samtec SFM series pairs with this socket in a complete 86-pin interconnect system?
The SFM-143-T2-H-D-A-K is designed to mate with Samtec TSM or SFM series 86-position dual-row headers sharing the 0.050-inch pitch. A properly matched header-socket pair provides a mechanical retention force sufficient for vibration environments and guarantees contact resistance below 20 milliohms per pin in typical operation.
For a compact mezzanine PCB stack, how does the SMT footprint of SFM-143-T2-H-D-A-K simplify assembly?
The surface-mount termination allows the SFM-143-T2-H-D-A-K to be placed and reflowed alongside other SMT components in a single pass, eliminating through-hole drilling and wave-soldering steps. The dual-row 86-pin layout spans approximately 54 mm in length, enabling dense mezzanine connections within a footprint of under 60 mm x 3 mm per connector.
Which high-reliability applications are best served by the SFM-143-T2-H-D-A-K?
Applications that benefit most include telecommunications line cards, FPGA evaluation boards with 86 or more I/O connections, and industrial embedded computing modules requiring stable contact integrity across -55°C to +125°C temperature ranges. The high-reliability plating and robust SMT termination also make this connector suitable for military and aerospace instrumentation where repeated mating cycles must exceed 500 insertions.
