Key Features
- 96-position dual-row socket strip at 0.050" (1.27 mm) fine pitch delivers very high signal density—twice that of standard 0.100" connectors in the same board length
- High-reliability contact system with gold-over-nickel plating maintains contact resistance below 20 mΩ through extended mating cycles in industrial and medical applications
- Surface-mount termination compatible with lead-free reflow soldering simplifies board assembly and eliminates through-hole drilling in high-layer-count PCB designs
Applications
The SFM-148-T2-F-D-A-K suits high-density signal interfaces in FPGA mezzanine cards, telecom line cards, and data acquisition modules where 96 signals must be routed in minimal PCB footprint. Its 0.050" fine pitch allows compact connector placement alongside high-speed differential pairs and power planes in multi-layer PCBs. Medical imaging systems and instrumentation platforms also rely on this socket strip for reliable plug-in card retention where card swap cycles require stable 96-pin connectivity.

Frequently Asked Questions
For a mezzanine card design with 96 signal lines, how much board space does the SFM-148-T2-F-D-A-K save compared to 0.100" connectors?
The SFM-148-T2-F-D-A-K at 0.050" (1.27 mm) pitch spans a body length of approximately 60.5 mm for 48 positions per row, whereas an equivalent 96-position connector at 0.100" pitch would require about 121 mm. This roughly 50% reduction in connector body length frees significant PCB area for decoupling capacitors, routing channels, and other components on densely populated mezzanine boards in communications and instrumentation applications.
How many mating cycles is the SFM-148-T2-F-D-A-K qualified for, and which applications benefit from this specification?
Samtec SFM series high-reliability socket strips are typically rated for a minimum of 100 mating cycles with gold-over-nickel plated contacts maintaining contact resistance below 20 mΩ. Applications such as plug-in test modules, hot-swap server blades, and field-replaceable FPGA cards that are inserted and removed dozens of times per year benefit from this rating, ensuring reliable 96-pin connectivity is maintained over the product's 5- to 10-year service life.
Is the SFM-148-T2-F-D-A-K interchangeable with the SFM-149-T2-FM-D-A-K in a revised PCB design that only needs 96 positions?
The SFM-148 (96 positions) and SFM-149 (98 positions) differ by 2 positions, so the PCB pad patterns and connector body lengths are not identical. The SFM-148-T2-F-D-A-K will fit a 48-positions-per-row footprint while the SFM-149 requires a 49-positions-per-row layout at the same 1.27 mm pitch. If a revised design targets exactly 96 signals, the SFM-148-T2-F-D-A-K is the correct choice and its footprint must be laid out to match the 96-position body length.
