Key Features
- 98-position dual-row layout on 0.050" (1.27 mm) pitch enabling high-density signal routing in minimal PCB area
- High-reliability socket construction with gold-plated contacts rated for repeated mating cycles
- Surface mount form factor supports reflow soldering and automated pick-and-place assembly processes
Applications
The SFM-149-L2-L-D-A is designed for high-density board-to-module and mezzanine interconnect applications where 98 signals must be routed across a compact 1.27 mm pitch interface. Typical uses include FPGA daughter-card interfaces, high-speed memory module sockets, and embedded computing carrier boards requiring reliable mating across hundreds of cycles. Its surface mount technology supports automated assembly in volume production environments such as telecommunications and industrial computing platforms.

Frequently Asked Questions
How many contacts does the SFM-149-L2-L-D-A provide and at what pitch?
The SFM-149-L2-L-D-A provides 98 total positions arranged in a dual-row configuration on a 0.050" (1.27 mm) pitch. This fine pitch allows routing of nearly 100 signals in the footprint that a 2.54 mm pitch connector would use for approximately 49 positions, significantly increasing interconnect density for FPGA and module designs.
For a removable FPGA mezzanine card, how many mating cycles is the SFM-149-L2-L-D-A rated to handle?
SAMTEC SFM-series high-reliability socket strips are designed for repeated mate/unmate cycles typical of development and test environments, generally rated for a minimum of 50 mating cycles while maintaining contact resistance below specified limits. The gold-plated contacts help preserve low contact resistance across these cycles, ensuring consistent signal integrity on 98 pins throughout the product's service life.
When should an engineer choose the SFM-149-L2-L-D-A over a 2.54 mm pitch dual-row socket?
The SFM-149-L2-L-D-A at 0.050" (1.27 mm) pitch occupies roughly half the board area compared to an equivalent 2.54 mm pitch socket for 98 positions. Engineers should choose it when PCB real estate is constrained to under 65 mm in the connector axis, or when mating to SAMTEC SFM-series header strips already specified in a module design. For applications where board space is generous and tooling supports 2.54 mm pitch, the coarser-pitch alternative may reduce assembly sensitivity to placement tolerances.
