What are the key features of SFM-144-L2-SM-D-LC?
- 88-position dual-row surface-mount socket strip with 0.050" (1.27 mm) pitch for maximum signal density in compact PCB footprints
- Board-lock (LC) retention clips mechanically anchor the socket to the PCB, resisting pull-out forces during repeated mating cycles
- High-reliability construction maintains consistent contact resistance across 88 positions in industrial and telecom applications
- Surface-mount termination enables reflow soldering integration into automated PCB assembly lines without through-hole drilling
- SM (surface mount) tail style provides stable solder joint geometry for reliable electrical connections on dense multilayer boards
What is SFM-144-L2-SM-D-LC used for?
The SFM-144-L2-SM-D-LC is used in high-density board-to-board mezzanine interconnect applications in telecom line cards, FPGA evaluation boards, and industrial computing modules where 88 signals must be routed reliably through a compact 0.050" pitch surface-mount socket. The board-lock feature ensures connector stability under vibration and mechanical stress encountered in rack-mounted and embedded industrial systems. Its high-reliability design suits long-lifecycle applications in networking infrastructure and defense electronics.

Frequently Asked Questions
How many positions does the SFM-144-L2-SM-D-LC provide and what is its pitch?
The SFM-144-L2-SM-D-LC offers 88 positions in a dual-row surface-mount arrangement with a 0.050" (1.27 mm) pitch, providing one of the higher-density options in the SAMTEC SFM series for applications requiring many signals through a compact SMT socket footprint.
What role does the board-lock (LC) feature play when using SFM-144-L2-SM-D-LC in vibration-prone equipment?
The LC board-lock on SFM-144-L2-SM-D-LC uses retention tabs that snap into PCB apertures, preventing the 88-position 0.050" pitch socket from lifting or shifting under vibration loads or repeated mating forces typical in rack-mounted telecom equipment, industrial control panels, and military-grade embedded computing assemblies.
How does SFM-144-L2-SM-D-LC compare to a lower-position SFM variant for FPGA board-to-board interfaces?
The SFM-144-L2-SM-D-LC provides 88 positions versus 80-position (SFM-140) or 60-position (SFM-130) variants, making it the appropriate choice when FPGA mezzanine card designs require more than 80 signal connections through a 0.050" pitch SMT socket interface while keeping the connector footprint within a single dual-row strip.
Is SFM-144-L2-SM-D-LC compatible with standard automated PCB assembly and reflow soldering?
Yes, the SFM-144-L2-SM-D-LC surface-mount termination style is fully compatible with automated pick-and-place machines and lead-free reflow soldering at peak temperatures up to 260°C, allowing the 88-position 0.050" pitch socket to be placed and soldered alongside other SMT components in a standard PCB assembly process.
