What are the key features of SFM-149-L2-SM-D-A?
- 98-position dual-row layout at 0.050" (1.27mm) pitch providing up to 196 contacts in a low-profile surface mount footprint
- High-reliability gold-plated contacts ensuring consistent electrical performance across thousands of mating cycles in demanding environments
- L2 lead length option offering precise standoff height control for controlled-impedance signal routing on high-speed PCB assemblies
What is SFM-149-L2-SM-D-A used for?
The SFM-149-L2-SM-D-A is well suited for high-speed mezzanine card interconnects, FPGA daughter boards, and backplane-to-module interfaces where 98 dual-row positions must be routed reliably at 0.050" pitch. Its surface mount configuration with L2 lead length supports controlled-impedance PCB designs used in telecommunications, server computing, and test instrument daughtercard assemblies. Engineers choose this socket strip when board-to-board interconnection density exceeds what standard 0.100" pitch solutions provide.

Frequently Asked Questions
How many total contact positions does the SFM-149-L2-SM-D-A support at 0.050" pitch?
The SFM-149-L2-SM-D-A provides 98 positions in a dual-row configuration at 0.050" (1.27 mm) pitch, delivering up to 196 individual contact points for routing high-density signal buses on surface mount mezzanine and daughter card assemblies.
For which high-speed PCB designs does the L2 lead length variant of the SFM-149 series offer an advantage?
The L2 lead length variant provides a specific standoff height that controls the air gap between mating boards, which helps manage differential impedance and crosstalk on high-speed signals above 1 Gbps in FPGA mezzanine cards, backplane modules, and server computing interconnects operating at 0.050" pitch.
When is SFM-149-L2-SM-D-A a better alternative to a 0.100" pitch connector for backplane designs?
When a design requires more than 100 signal lines in a constrained board area, the SFM-149-L2-SM-D-A at 0.050" pitch routes up to 196 contacts in roughly half the length compared to a 0.100" pitch alternative, reducing PCB real estate while maintaining the high-reliability SMT attachment needed for backplane and server blade applications.
