Key Features
- 62 contacts in dual-row 0.050" (1.27 mm) pitch for maximum signal density in compact board-to-board interconnects
- Female (FM) mating interface with gold-over-nickel contact finish delivers low contact resistance and high insertion-cycle reliability
- Surface mount termination enables compatibility with automated SMT reflow assembly processes and IPC-7351 land patterns
- High-reliability SFM series design rated for industrial, telecom, and high-speed digital applications
Applications
The SFM-131-02-FM-D-A-K is deployed in high-density board-to-board applications such as FPGA mezzanine cards, DSP daughter boards, and network switch line cards where 62 signal lines must be routed in a minimal 0.050" pitch footprint. Its dual-row SMT socket configuration is ideal for high-speed digital interfaces in telecommunications backplanes, test and measurement platforms, and embedded computing modules.

Frequently Asked Questions
How does the 62-position count of the SFM-131-02-FM-D-A-K compare to the SFM-126 and SFM-125 variants in the same series?
The SFM-131-02-FM-D-A-K provides 62 contacts versus 52 contacts on the SFM-126 and 50 contacts on the SFM-125, all sharing the same 0.050" (1.27 mm) dual-row pitch. The SFM-131 body is proportionally longer, accommodating 10 additional signal or power connections within the same connector family footprint, which is useful when additional I/O lines are needed without switching to a different connector series or pitch.
What high-speed signal performance can the SFM-131-02-FM-D-A-K deliver at data rates above 1 Gbps?
SAMTEC SFM series connectors support differential data rates of 2.5 Gbps or more per pair, with characteristic impedance near 50 Ω per contact and insertion loss typically below 1 dB at 1 GHz. The SFM-131-02-FM-D-A-K can therefore carry LVDS, SGMII, PCIe Gen 1, or DDR3 address lines with acceptable signal integrity when combined with proper PCB routing—controlled differential pair spacing of 5 mil gap, 100 Ω differential impedance, and length-matched traces.
Does the SFM-131-02-FM-D-A-K require a specific mating header, and what SAMTEC part numbers mate with it?
The SFM-131-02-FM-D-A-K mates with SAMTEC TSM or TFM series headers using a 0.050" (1.27 mm) dual-row, 62-position male pin arrangement. Compatible mating headers from the TSM-131 or TFM-131 families provide matching 62-pin configurations. The gold-over-nickel contact finish on both the socket and header sides ensures low mating force of approximately 30 gf per contact while maintaining contact resistance below 20 mΩ throughout the connector's rated insertion life.
For a portable medical instrument PCB design, how does the SFM-131-02-FM-D-A-K help reduce board area compared to 0.100" alternatives?
At 0.050" (1.27 mm) pitch dual-row, the SFM-131-02-FM-D-A-K occupies roughly 25% of the PCB footprint that a comparable 0.100" pitch 62-position connector would require. In a portable medical instrument where total PCB area may be constrained to under 80 cm², replacing a 0.100" connector with the SFM-131 can free up approximately 4–6 cm² of board space for additional circuitry or battery capacity, directly improving device portability and functionality.
