What are the key features of SFM-146-02-L-D-DS?

92-position dual-row SMT socket strip at 0.050 inch (1.27 mm) pitch enables ultra-high-density signal routing in mezzanine assemblies
High-reliability long-wipe gold-plated contacts maintain contact resistance below 20 milliohms across 500+ mating cycles
Dual solder tail (DS) termination configuration provides two solder points per contact for superior PCB pull-strength and vibration resistance
Fine 0.050 inch pitch dual-row layout delivers 92 signals within approximately 60 mm board length for compact mezzanine modules

What is SFM-146-02-L-D-DS used for?

The SFM-146-02-L-D-DS is suited for high-density mezzanine card interconnect in FPGA processing boards, network switch backplanes, and military computing modules where 92 signal channels must fit within a compact 0.050 inch pitch footprint. The dual solder tail (DS) termination provides additional mechanical strength for mezzanine assemblies subject to vibration in transportation and defense electronics applications. Long-wipe gold contacts ensure reliable signal integrity for high-speed differential pairs and parallel data buses across hundreds of field insertion cycles.

Frequently Asked Questions

What is the pin count and contact pitch of the SFM-146-02-L-D-DS, and how does it compare to 0.100 inch pitch alternatives?

The SFM-146-02-L-D-DS provides 92 total positions in a dual-row layout at 0.050 inch (1.27 mm) pitch, fitting 46 contacts per row within approximately 60 mm of board length. A 0.100 inch pitch connector carrying the same 92 signals would require approximately 120 mm of board length, so the SFM-146-02-L-D-DS saves roughly 60 mm of PCB real estate — a decisive advantage in compact mezzanine designs for FPGA modules and network processing blades.

How does the dual solder tail (DS) option on the SFM-146-02-L-D-DS improve mechanical reliability versus a single-tail configuration?

The DS (dual solder tail) configuration provides two SMT solder pads per contact position instead of one, doubling the solder joint area and increasing the PCB pull-off force for the 92-position connector by approximately 40% to 60%. This is critical in mezzanine assemblies experiencing vibration above 5 g or shock loads above 50 g, such as those found in airborne radar processing modules, vehicle-mounted computing platforms, and industrial robotic controllers where solder joint fatigue is a primary failure mode.

Which high-speed protocols can be reliably routed through the SFM-146-02-L-D-DS in an FPGA mezzanine application?

The SFM-146-02-L-D-DS supports differential signaling at 0.050 inch pitch for LVDS at several hundred megahertz, PCIe Gen 1 at 2.5 Gbps, and SGMII at 1.25 Gbps when adjacent pairs are routed with 100 ohm differential impedance. With 92 positions, the connector can carry up to 20 differential pairs for high-speed I/O, plus 12 power and ground pins, enabling an 8-lane PCIe or 16-channel LVDS sensor interface in compact FPGA mezzanine modules measuring under 100 mm by 100 mm.

How long does this connector last in mating cycle applications, and what contact finish supports that lifetime?

The SFM-146-02-L-D-DS uses gold-plated long-wipe contacts rated for a minimum of 500 mating cycles while maintaining contact resistance below 20 milliohms across all 92 positions. Gold plating prevents oxidation in operating environments from -55°C to +125°C, and the long-wipe geometry provides a self-cleaning action that removes surface contamination with each insertion, extending reliable contact life in field-replaceable mezzanine modules that are re-seated during maintenance and system upgrades.
