Key Features
- 94-position dual-row layout on 0.050-inch (1.27 mm) pitch enabling high-density board-to-board signal connections in compact SMT footprints
- High-reliability female micro-terminal contacts with gold plating rated for 200+ mate-unmate cycles in demanding environments
- Surface-mount termination compatible with standard SMT reflow processes, eliminating through-hole drilling and simplifying PCB manufacturing
Applications
The SFM-147-02-FM-D-A-K is designed for high-density board-to-board interconnect applications in telecommunications, test and measurement equipment, and industrial control backplanes where 94 signals must be routed across a 0.050-inch pitch interface. Its surface-mount construction suits automated assembly lines and miniaturized system designs where vertical space is limited. The high-reliability contacts also make it suitable for ruggedized computing platforms and embedded systems exposed to vibration or thermal cycling.

Frequently Asked Questions
What pitch and pin count does the SFM-147-02-FM-D-A-K provide, and what board-to-board stack height does it support?
The SFM-147-02-FM-D-A-K offers 94 positions arranged in a dual row on a 0.050-inch (1.27 mm) pitch, providing a high-density signal interface in a compact SMT footprint. It mates with compatible SAMTEC header strips and supports low-profile stack heights typically in the 8 mm to 12 mm range depending on the mating header selected.
For which high-density interconnect scenarios is the SFM-147-02-FM-D-A-K a better choice than a standard 2.54 mm pitch connector?
When PCB real estate is constrained and 94 signals must cross a board-to-board interface, the 1.27 mm pitch of the SFM-147-02-FM-D-A-K reduces connector footprint by approximately 75% compared to a 2.54 mm pitch alternative, making it ideal for blade servers, FPGA mezzanine cards, and compact RF modules where every square millimeter counts.
How many mate-unmate cycles are the contacts rated for, and what contact plating is used?
SAMTEC's SFM-series micro-terminal contacts are rated for a minimum of 200 mate-unmate cycles with gold-over-nickel plating on the contact surfaces. This gold plating ensures low and stable contact resistance below 20 milliohms throughout the rated cycle life, making the connector suitable for field-serviceable or frequently reconfigured systems.
Is the SFM-147-02-FM-D-A-K compatible with standard SMT reflow soldering, and what temperature profile does it support?
Yes, the SFM-147-02-FM-D-A-K is designed for surface-mount reflow soldering and is compatible with lead-free reflow profiles up to 260°C peak temperature per IPC/JEDEC J-STD-020. The SMT pads allow standard pick-and-place placement, and the connector body is rated to withstand the thermal stress of up to 3 reflow passes without dimensional distortion.
