Key Features
- 98-position dual-row SMT socket strip with 0.050" (1.27 mm) pitch enabling very high-density board-to-board mating in space-constrained electronics
- Gold-plated contacts (A suffix) providing low contact resistance under 20 mΩ and corrosion protection for high-reliability applications requiring 1000+ mating cycles
- T2 solder tail configuration optimized for SMT reflow soldering up to 260°C, compatible with SAMTEC TFM mating header series
Applications
The SAMTEC SFM-149-T2-L-D-A-K high-reliability socket strip is engineered for dense board-to-board and mezzanine card interconnects in FPGA carrier boards, high-speed data acquisition modules, and aerospace electronics. Its 98-position dual-row layout at 0.050" pitch allows 196 signals to be routed through a minimal PCB footprint, supporting high signal count interfaces in compact form factors. This connector is commonly specified in FMC (FPGA Mezzanine Card) standards, military avionics, and medical imaging equipment requiring reliable repeated mating performance.

Frequently Asked Questions
What total signal count does SFM-149-T2-L-D-A-K support, and what pitch does it use?
The SFM-149-T2-L-D-A-K supports 98 positions in a dual-row arrangement at 0.050" (1.27 mm) pitch, providing connections for up to 98 signals across both rows. This high position count with compact 1.27 mm pitch makes it suitable for FPGA mezzanine cards, high-speed DAQ systems, and other dense digital interconnect applications where board space is critical.
How does gold-plated contact finish in SFM-149-T2-L-D-A-K benefit high-reliability aerospace or medical applications?
Gold-plated contacts in SFM-149-T2-L-D-A-K deliver contact resistance below 20 mΩ with excellent corrosion immunity, supporting 1000+ mating cycles without degradation. In aerospace and medical electronics where connector failure is not tolerable, gold plating maintains consistent electrical performance across temperature cycles from -55°C to +125°C and prevents oxidation in humid or chemically active environments.
Is SFM-149-T2-L-D-A-K compatible with VITA 57 FMC standard mezzanine interfaces?
SAMTEC SFM series socket strips at 0.050" (1.27 mm) pitch with T2 SMT tails are commonly used in VITA 57.1 FMC (FPGA Mezzanine Card) compliant designs, where 400-pin high-pin-count connectors aggregate multiple SFM strips. The 98-position dual-row SFM-149-T2-L-D-A-K format fits standard FMC footprint sub-sections, supporting high-speed differential signal routing at data rates up to 10 Gbps per lane.
