Frequently Asked Questions
What is the pin configuration and pitch of the SFM-143-02-LM-D-A-K?
The SFM-143-02-LM-D-A-K features 86 positions arranged in a dual-row configuration with a 0.050" (1.27 mm) pitch. This compact spacing accommodates high-density signal routing on surface-mount PCBs, making it suitable for applications requiring 43 pins per row in a minimal footprint.
Which embedded computing and FPGA board designs benefit most from the SFM-143-02-LM-D-A-K?
Embedded computing modules, FPGA development platforms, and SOM (System-on-Module) designs benefit most from this 86-position SMT socket. Its 1.27 mm pitch and dual-row layout supports high-speed parallel bus connections, accommodating data rates suitable for DDR memory interfaces, PCIe edge connectors, and LVDS signal routing with low insertion loss.
How does the SFM-143-02-LM-D-A-K compare to through-hole socket alternatives for industrial applications?
Compared to through-hole alternatives, the SFM-143-02-LM-D-A-K offers a lower-profile SMT assembly that reduces board height by several millimeters, enabling more compact enclosure designs. The surface-mount termination is compatible with reflow soldering processes, reducing assembly time. However, through-hole sockets provide greater mechanical retention force—an important consideration for high-vibration industrial environments operating across -55°C to +125°C temperature ranges.
What mating connector family is compatible with the SFM-143-02-LM-D-A-K for board-to-board stacking?
The SFM-143-02-LM-D-A-K from SAMTEC mates with corresponding SFM-series plug connectors and is compatible with SAMTEC's 0.050" pitch micro-strip connector family. Stacking heights of 8 mm, 11 mm, and other standard board-to-board spacing options are available, accommodating configurations with 2 mm to 12 mm between mated boards.
