What are the key features of SFM-149-02-FM-D-A?
- 98 positions in a dual-row, 0.050 inch (1.27 mm) pitch SMT configuration for high-density, space-efficient signal routing
- High-reliability friction-mate contact design rated for demanding environments including vibration and thermal cycling
- Surface-mount footprint eliminates through-hole drilling, enabling compact multi-layer PCB designs with up to 98 signals per connector
What is SFM-149-02-FM-D-A used for?
The SFM-149-02-FM-D-A is used in high-density embedded computing modules, FPGA daughter cards, and military or aerospace interconnect boards where 98 signals must be reliably routed at 0.050 inch pitch in a compact SMT footprint. Its high-reliability rating makes it appropriate for industrial automation controllers and test-and-measurement backplanes subject to vibration and wide temperature swings. The friction-mate design also suits rapid prototyping systems requiring repeated plug-in and pull-out cycles without solder.

Frequently Asked Questions
How many signal positions and what pitch does SFM-149-02-FM-D-A support in a dual-row SMT format?
SFM-149-02-FM-D-A provides 98 positions arranged in two rows on a 0.050 inch (1.27 mm) pitch, giving 49 contacts per row in a surface-mount socket configuration that is roughly half the board footprint of equivalent 0.100 inch pitch connectors, enabling very high signal density on compact embedded computing and FPGA daughter boards.
For a vibration-prone aerospace application, why is SFM-149-02-FM-D-A described as high-reliability?
SAMTEC's SFM series uses a friction-mate contact geometry that maintains secure electrical connection under mechanical vibration and thermal cycling, which is why the SFM-149-02-FM-D-A is rated high-reliability for aerospace and military designs that demand sustained contact integrity across 98 positions at 0.050 inch pitch without soldered mating.
When would a board designer select SFM-149-02-FM-D-A over a 0.100 inch pitch alternative for a FPGA carrier card?
When an FPGA carrier card must route 98 or more signals between two boards but the available connector footprint area is limited to roughly half the space required by 0.100 inch pitch headers, the SFM-149-02-FM-D-A at 0.050 inch (1.27 mm) pitch halves the connector length while maintaining full 98-position signal capacity in a surface-mount body.
Is SFM-149-02-FM-D-A stocked in quantity for production procurement, and what is its mounting method?
SFM-149-02-FM-D-A is a surface-mount connector that undergoes standard reflow soldering on a PCB land pattern compatible with the 0.050 inch (1.27 mm) pitch dual-row footprint, and SAMTEC typically maintains stock of the SFM series for volume procurement, with the 98-position variant available from authorized distributors worldwide for production builds.
