What are the key features of SFM-149-T2-S-D-A?
- 98-position dual-row configuration at 1.27 mm (0.050") pitch delivering 98 contacts for high-density board-to-board interconnects
- High-reliability socket construction supporting repeated mating cycles for modular and field-serviceable hardware designs
- Surface-mount termination enabling automated SMT pick-and-place assembly in high-volume production
- SAMTEC SFM series compatibility with standard 0.050" pitch TFM and HFM headers for mezzanine module stacking
What is SFM-149-T2-S-D-A used for?
The SFM-149-T2-S-D-A suits high-density FPGA daughter card interfaces, processor module carrier boards, and multi-function mezzanine stacks where 1.27 mm pitch maximizes I/O count within constrained PCB footprints. Its 98-contact dual-row layout supports simultaneous signal distribution across memory expansion, RF module, and co-processor interconnects without multiple connectors. The high-reliability socket design is also well suited for development evaluation platforms, automated test equipment, and military or aerospace modules requiring frequent and reliable board insertion cycles.

Frequently Asked Questions
What pitch and total contact count does the SFM-149-T2-S-D-A offer compared to standard 2.54 mm pitch connectors?
The SFM-149-T2-S-D-A uses a 1.27 mm (0.050") pitch with 98 positions in a dual-row arrangement, providing 98 total contacts. This pitch is twice as dense as standard 2.54 mm connectors, allowing the same board length to carry twice the signal count, which is critical for FPGA I/O buses, processor address and data lines, and high-speed parallel interfaces in compact mezzanine designs.
Which SAMTEC header series mates with the SFM-149-T2-S-D-A socket strip?
The SFM-149-T2-S-D-A mates with SAMTEC TFM or HFM series 1.27 mm (0.050") pitch dual-row headers, as well as compatible 98-position 2-row male headers from other manufacturers following the same 0.050" pitch standard. Designers can also use SAMTEC's configurable connector selector to identify exact mating partners for the 98-contact, dual-row layout on opposing boards.
How does the SFM-149-T2-S-D-A compare to the SFM-139-L2-H-D-A in terms of contact count and application fit?
The SFM-149-T2-S-D-A provides 98 contacts versus the SFM-139-L2-H-D-A's 78 contacts, both at 1.27 mm (0.050") pitch in dual-row surface-mount format. Designers needing wider I/O buses, such as 96-bit or wider parallel interfaces for FPGA or memory modules, should select the SFM-149-T2-S-D-A, while applications requiring fewer than 80 signals can use the shorter SFM-139 to reduce board length.
Is the SFM-149-T2-S-D-A suitable for automated SMT production, and what reflow temperature should be observed?
Yes, the SFM-149-T2-S-D-A is designed for surface-mount reflow assembly using standard SMT pick-and-place and solder paste processes. SAMTEC recommends following IPC-J-STD-020 moisture sensitivity guidelines and limiting peak reflow to 260°C for no more than 10 seconds to protect the 98-position socket housing. Proper footprint design using SAMTEC's published land pattern ensures reliable solder joints across all 98 contacts.
