Key Features
- 96 positions (2x48) at 1.27 mm (0.050 inch) pitch provides one of the highest channel-count SFM sockets for routing signals and power across board-to-board interfaces
- -K keying option physically prevents incorrect connector orientation, eliminating mis-mating errors during assembly and field servicing
- Surface-mount termination reflows at standard 260°C lead-free profiles, enabling automated SMT placement without through-hole PCB drilling
- High-reliability SAMTEC SFM construction with gold-plated contacts maintains low contact resistance across hundreds of mating cycles
Applications
The SFM-148-02-S-D-A-K is used in high-channel-count mezzanine assemblies such as FPGA accelerator cards, radar signal-processing boards, and high-speed data acquisition modules where 96 signals must be transferred between boards at the compact 1.27 mm pitch. The -K keying feature is particularly valuable in production environments or field-replaceable module designs where correct connector orientation must be guaranteed without visual inspection. Its surface-mount form factor suits dense multi-layer PCBs in defense, telecom, and scientific instrumentation applications.

Frequently Asked Questions
How many signal channels does SFM-148-02-S-D-A-K support and how are the contacts arranged?
The SFM-148-02-S-D-A-K supports 96 channels in a dual-row layout of 2 rows by 48 contacts at 1.27 mm (0.050 inch) pitch. This provides a 96-pin interface in a connector body approximately 61 mm long, making it suitable for high-density board-to-board assemblies where more than 90 signals must pass across the mezzanine interface.
What is the purpose of the -K option in SFM-148-02-S-D-A-K and when should it be specified?
The -K suffix adds a polarization key to the connector housing that physically prevents insertion in the wrong orientation. It should be specified whenever the mating connector pair could otherwise be inserted 180 degrees rotated, which would apply 96 signals to the wrong pins and damage the boards. It is mandatory in automated board assembly lines and field-replacement scenarios where visual orientation cues are unreliable.
Which mating connector mates with SFM-148-02-S-D-A-K to form a complete board-stacking pair?
SFM-148-02-S-D-A-K mates with SAMTEC SFH-148 series headers at 1.27 mm pitch, 2-row, 48-position-per-row configuration. The corresponding SFH header must also carry the -K keying feature to form a polarized mating pair. The gold-to-gold contact interface in the mated assembly provides typical contact resistance below 20 mΩ per pin and supports signal frequencies above 1 GHz.
How does SFM-148-02-S-D-A-K compare to a 96-pin 2.54 mm pitch connector for a compact FPGA mezzanine card?
At 1.27 mm pitch, the SFM-148-02-S-D-A-K connector occupies a body length of approximately 61 mm versus approximately 122 mm for an equivalent 2.54 mm pitch connector — a 50% reduction in connector footprint length. For a compact FPGA mezzanine card where board width is constrained to under 80 mm, the 1.27 mm variant is often the only viable 96-pin option.
