Key Features
- 92-position dual-row SMT socket with 0.050 inch (1.27 mm) pitch supports 46 signals per row, enabling dense I/O routing for FPGA and processor module boards in a minimal PCB footprint
- High-reliability socket strip construction with precision contacts maintains low insertion loss and consistent mating force across -55°C to +125°C operating temperature range
- Surface-mount termination eliminates through-hole drilling, allowing double-sided PCB population and simplifying high-volume SMT reflow assembly with standard 260°C peak reflow profiles
Applications
The SFM-146-T2-S-D-A is suited for FPGA mezzanine cards, processor-on-module (SOM) carrier boards, and high-speed backplane interconnects where 92 positions at 0.050 inch pitch must be accommodated in a surface-mount form factor. Its dual-row arrangement allows simultaneous routing of differential pairs, single-ended signals, and power rails within a compact connector body. The high-reliability socket construction meets requirements for industrial automation, medical imaging, and ruggedized computing platforms that demand stable contact performance over extended service life.

Frequently Asked Questions
How does the SFM-146-T2-S-D-A differ from a standard 0.100 inch pitch socket strip in board density?
The SFM-146-T2-S-D-A uses a 0.050 inch (1.27 mm) pitch versus the 0.100 inch (2.54 mm) standard, fitting 92 positions in roughly half the PCB area of an equivalent 0.100 inch socket. This makes it suitable for high-density FPGA I/O headers and SOM carrier boards where saving 5 mm to 10 mm of board length is critical for miniaturization targets.
What SMT reflow conditions is the SFM-146-T2-S-D-A compatible with?
The connector is designed for surface-mount reflow soldering and is compatible with lead-free SAC305 solder paste processes with a peak reflow temperature of up to 260°C for a maximum of 30 seconds above 217°C liquidus. This ensures compatibility with standard RoHS-compliant PCB assembly lines without requiring selective or hand-soldering exceptions.
In which rugged or industrial applications would the SFM-146-T2-S-D-A be the preferred interconnect?
The SFM-146-T2-S-D-A is preferred in industrial computing, medical imaging systems, and defense electronics where the high-reliability dual-row socket must maintain contact resistance below 20 milliohms across a -55°C to +125°C temperature range and survive over 500 insertion cycles with copper alloy contacts finished with gold over nickel for corrosion resistance.
What mating header series is the SFM-146-T2-S-D-A designed to accept?
The SFM-146-T2-S-D-A mates with SAMTEC TSM and SSM series square-post headers using the same 0.050 inch (1.27 mm) dual-row pin grid. The precision machined contacts accept a standard 0.025 x 0.025 inch square pin, providing approximately 100 g insertion force per contact and reliable continuity rated up to 1 A per pin at 30 V DC maximum.
