What are the key features of SFM-144-L2-S-D-LC?
- 88-position dual-row configuration at 0.050" (1.27 mm) pitch for maximum signal channel density in compact surface mount board-to-board designs
- Standard (S) mating height provides a balanced board-to-board standoff suitable for most embedded computing and communications module applications
- High-reliability gold-plated contacts with LC (low-clearance) retention ensure secure and stable engagement across all 88 positions under vibration
- Surface mount termination compatible with automated reflow soldering and high-density PCB assembly processes
What is SFM-144-L2-S-D-LC used for?
The SFM-144-L2-S-D-LC is used in high pin-count board-to-board interconnect applications such as FPGA expansion boards, processor daughter cards, and multi-channel data acquisition modules where 88 signals at 1.27 mm pitch must be reliably connected. Its large 88-position dual-row format consolidates what would otherwise require multiple smaller connectors into a single high-density interface. Defense electronics, telecommunications line cards, and industrial computing platforms benefit from its high contact reliability over wide temperature ranges.

Frequently Asked Questions
What is the total pin count and row configuration of the SFM-144-L2-S-D-LC, and what bus widths does it support?
The SFM-144-L2-S-D-LC has 88 total positions in a dual-row layout with 44 pins per row at 0.050" (1.27 mm) pitch. This supports wide bus configurations such as a 64-bit data bus with 24 address or control lines, or a 32-bit data bus combined with 56 control, power, and ground signals — making it well-suited for high-bandwidth FPGA, DSP, or processor module interfaces.
How does the LC retention feature of the SFM-144-L2-S-D-LC benefit high-vibration environments?
The LC (low-clearance) retention system in the SFM-144-L2-S-D-LC provides an interference-fit latching mechanism that holds the mated header in place against vibration and shock loads. For defense, aerospace, and industrial machinery applications where the 88-position connector may be subjected to continuous mechanical stress, this retention prevents intermittent disconnects that could disrupt critical signal paths.
What is the difference between the SFM-144 and smaller SFM-119 or SFM-112 variants when designing a high-channel-count interface?
The SFM-144-L2-S-D-LC offers 88 positions versus 38 positions (SFM-119) or 24 positions (SFM-112), all at the same 0.050" (1.27 mm) pitch. Choosing the SFM-144 reduces the number of connectors needed from 3 or more smaller units to a single connector, simplifying PCB layout, reducing BOM complexity, and lowering total connector height on the board while maintaining the same 1.27 mm pitch standard.
Which Samtec headers mate with the SFM-144-L2-S-D-LC for a complete board-to-board assembly?
The SFM-144-L2-S-D-LC mates with Samtec TSM and SFM series dual-row headers at 0.050" (1.27 mm) pitch in an 88-position configuration. Compatible mating headers are available in surface mount and through-hole termination styles, with various stack heights, allowing designers to select the board-to-board separation that best fits their enclosure and component clearance requirements.
