Key Features
- 88-position dual-row layout on 1.27mm (0.050") pitch delivering high-density signal routing in a compact SMT socket footprint
- High-reliability socket strip construction with gold-plated contacts ensuring low contact resistance across repeated mating cycles
- Surface-mount termination compatible with standard SMT reflow processes for automated high-volume PCB assembly
Applications
The SFM-144-T2-LM-D-A-K is designed for high-density board-to-board and mezzanine module interconnects in FPGA development boards, embedded computing modules, and RF front-end cards where 88 signals must be routed across a connector interface on a fine 1.27mm pitch. Its high-reliability construction and surface-mount profile make it suitable for industrial computers, defense electronics, and test equipment requiring repeated plug-unplug cycles with consistent electrical performance. The compact 0.050" pitch allows significantly higher pin density than standard 0.100" connectors, enabling smaller PCB form factors.

Frequently Asked Questions
What is the pin pitch of the SFM-144-T2-LM-D-A-K, and how does 0.050" compare to standard 0.100" connectors in board density?
The SFM-144-T2-LM-D-A-K uses a 1.27mm (0.050") pitch, which is half the 2.54mm standard 0.100" pitch, allowing twice the pin density per unit length and enabling 88 contacts to be routed in a connector body roughly half the length of an equivalent 0.100" part.
How many mating positions does the SFM-144-T2-LM-D-A-K provide, and how are they arranged across the two rows?
The SFM-144-T2-LM-D-A-K provides 88 mating positions total in a dual-row configuration, meaning 44 contacts per row on the 1.27mm (0.050") pitch, which supports dense signal buses, power rails, and control lines simultaneously in FPGA mezzanine and embedded computing module designs.
Is the SFM-144-T2-LM-D-A-K suited for high-reliability applications requiring repeated plug-unplug cycles?
Yes, SAMTEC's SFM series uses high-reliability socket strip construction with gold-plated contacts rated for a specified number of mating cycles, making the SFM-144-T2-LM-D-A-K appropriate for defense, industrial, and test equipment applications where field-replaceable modules are plugged and unplugged many times over a product's life.
Does the surface-mount termination of the SFM-144-T2-LM-D-A-K support standard SMT reflow assembly?
Yes, the SMT (surface-mount) termination style of the SFM-144-T2-LM-D-A-K is compatible with standard solder paste and reflow oven processes at typical lead-free reflow temperatures around 260°C peak, enabling it to be placed by automated pick-and-place machines alongside other SMT components in a single reflow pass.
