What are the key features of SFM-146-T2-FM-D-A?
- 92-position dual-row layout at 0.050-inch (1.27 mm) pitch delivering high-density interconnect in a compact surface-mount footprint
- High-reliability socket strip construction rated for demanding mezzanine and board-to-board applications requiring consistent contact performance
- Surface-mount termination compatible with standard reflow soldering processes enabling automated SMT assembly without through-hole drilling
What is SFM-146-T2-FM-D-A used for?
The SFM-146-T2-FM-D-A is designed for high-density mezzanine board stacking in telecommunications line cards, server backplanes, and embedded computing modules where 92 signal and power contacts must be routed in a minimal PCB footprint. Its 0.050-inch pitch and dual-row configuration support high pin-count FPGA daughter cards, memory modules, and industrial I/O expansion boards that require reliable SMT mating interfaces.

Frequently Asked Questions
How many positions does the SFM-146-T2-FM-D-A provide and what is its contact pitch?
The SFM-146-T2-FM-D-A is a 92-position dual-row socket strip with a 0.050-inch (1.27 mm) contact pitch. This combination gives designers 46 contacts per row in a compact surface-mount package, supporting high-density signal routing for FPGA mezzanine cards, memory daughter boards, and multi-function I/O expansion modules where space is at a premium.
Is the SFM-146-T2-FM-D-A suitable for automated SMT reflow assembly, and what mounting style does it use?
Yes, the SFM-146-T2-FM-D-A uses surface-mount terminations compatible with standard SMT reflow soldering. The SM designation in the SFM series confirms solder-mount pins, allowing pick-and-place equipment to handle the 92-position connector at 0.050-inch pitch without manual through-hole insertion. This is advantageous for high-volume PCB assembly lines targeting low placement cycle times.
Which SAMTEC mating connector pairs with the SFM-146-T2-FM-D-A for a complete board-to-board stack?
The SFM-146-T2-FM-D-A is part of SAMTEC's SFM socket series, which mates with the corresponding SSM (Surface Mount Strips) or TSM header series at 0.050-inch pitch. For a 92-position dual-row mated pair, designers should select a TSM-146 or SSM-146 header with matching 1.27 mm pitch and appropriate stacking height — typically 2 mm, 4 mm, 8 mm, or 12 mm — to achieve the required board separation in the mezzanine stack.
