Key Features
- 98-position dual-row layout at 0.050" (1.27 mm) pitch enables very high signal density in compact PCB footprints
- High-reliability socket strip construction with gold-over-nickel contacts ensures low contact resistance and extended mating durability across 100+ mating cycles
- Surface-mount termination with tape-and-reel compatible packaging supports fully automated pick-and-place assembly for high-volume production
Applications
The SFM-149-T2-FM-D-A-K is designed for high-density signal interconnects in mezzanine card applications, FPGA daughter boards, and communications equipment where board real estate is limited. Its 0.050" fine pitch allows 98 signals to be routed in a footprint roughly half the size of standard 0.100" connectors. Engineers building test and measurement instruments or medical electronics benefit from the high-reliability contact system rated for demanding mating cycle requirements.

Frequently Asked Questions
How does the 0.050" pitch of the SFM-149-T2-FM-D-A-K compare to standard 0.100" connectors for signal density?
At 0.050" (1.27 mm) pitch, the SFM-149-T2-FM-D-A-K accommodates 98 contacts in roughly half the board length required by a standard 0.100" pitch connector carrying the same number of signals. This 2x improvement in linear density is critical for mezzanine cards, FPGA daughter boards, and compact communications modules where every square millimeter of PCB area is valuable.
Which applications benefit most from choosing the SFM-149-T2-FM-D-A-K's high-reliability socket strip design?
Applications with frequent card insertion cycles—such as test and measurement systems, hot-swap server blades, and modular medical devices—benefit most from the high-reliability socket strip construction. Gold-plated contacts maintain low contact resistance below 20 mΩ after 100+ mating cycles, ensuring signal integrity in differential pairs and high-speed data lines running at multi-Gbps rates.
Can the SFM-149-T2-FM-D-A-K be used as a direct swap for a lower-pin-count SFM series socket in a revised PCB layout?
The SFM-149-T2-FM-D-A-K follows Samtec's SFM series footprint rules at 0.050" pitch, but the 98-position (49 pins per row) body length differs from shorter variants. Direct swap is possible only if the PCB pads and keep-out zones accommodate 98 positions. For a lower count such as 80 positions, the SFM-140 series would be the correct substitute, maintaining the same 0.050" pitch and dual-row row spacing.
