What are the key features of SFM-144-T2-S-D-LC?
- 88-position dual-row layout at 0.050" (1.27 mm) pitch delivers very high signal density in a surface mount socket footprint suitable for mezzanine PCB stacking
- Board lock (LC) feature mechanically anchors the connector to the PCB, providing resistance to lateral forces and vibration without compromising solderability
- High-reliability socket strip construction ensures consistent contact force and low insertion resistance across repeated mating cycles in demanding applications
What is SFM-144-T2-S-D-LC used for?
The SFM-144-T2-S-D-LC is used in high-density mezzanine interconnects for FPGA modules, embedded computing carrier boards, and compact RF signal processing assemblies requiring 88 reliable connections at 0.050" pitch. The board lock feature makes it especially suitable for portable or vehicle-mounted systems subject to mechanical shock and vibration, ensuring the connector remains securely mounted during operation.

Frequently Asked Questions
What mechanical retention does the LC board lock on the SFM-144-T2-S-D-LC provide?
The LC (board lock) feature on the SFM-144-T2-S-D-LC consists of press-fit tabs that anchor the connector body into PCB holes, providing mechanical retention against lateral pull forces typically exceeding 5 N. This prevents the connector from shifting or peeling off during vibration or handling of the assembled PCB, which is critical for 88-pin interfaces in industrial or portable equipment subject to IEC 60068-2-6 vibration testing.
How does the 0.050" pitch of the SFM-144-T2-S-D-LC compare to .100" pitch connectors for a high-pin-count design?
At 0.050" (1.27 mm) pitch, the SFM-144-T2-S-D-LC fits 88 dual-row positions in a board footprint roughly 56 mm long — approximately half the length of an equivalent .100" pitch connector with the same pin count. This 50% reduction in connector length directly translates to PCB area savings, enabling designers to route 88 signals in systems where board space is too constrained for standard pitch alternatives.
Which FPGA or processor module designs can benefit from the SFM-144-T2-S-D-LC?
FPGA system-on-module (SOM) and computer-on-module (COM) designs that require 88 or fewer I/O connections between a carrier board and a module board can directly use the SFM-144-T2-S-D-LC. Its 0.050" pitch dual-row layout is compatible with SAMTEC TSM mating header families and can carry mixed signal types including 1.8 V LVDS pairs, 3.3 V GPIO, and low-current power rails up to 1 A per pin.
