Key Features
- 56-position dual-row SMD socket at 0.050" (1.27 mm) pitch delivering 112 contacts in a compact PCB footprint
- High-reliability contact design rated for extended mating cycles with consistent low insertion force
- Tape-and-reel (TR) packaging supports high-volume automated SMT pick-and-place assembly
- Surface-mount termination style eliminates through-hole drilling, reducing PCB manufacturing cost and layer stack-up
Applications
The SFM-128-T2-L-D-A-K-TR is used in high-density board-to-board and board-to-mezzanine interconnect designs found in embedded computing platforms, FPGA daughter cards, and advanced instrumentation systems requiring 56-position dual-row mating at 0.050" pitch. The tape-and-reel format ensures consistent placement accuracy in automated SMT manufacturing. Its compact surface-mount profile makes it well-suited for multi-layer PCB designs with tight height constraints.

Frequently Asked Questions
How many total contacts does the SFM-128-T2-L-D-A-K-TR socket provide?
The SFM-128-T2-L-D-A-K-TR provides 112 total contacts arranged as 56 positions in a dual-row 0.050" (1.27 mm) pitch configuration, enabling high-density signal routing between stacked PCBs in a compact SMD footprint.
For a high-speed FPGA mezzanine design, how suitable is the SFM-128-T2-L-D-A-K-TR at 0.050" pitch?
The 0.050" (1.27 mm) pitch and 56-position dual-row layout make this socket strip well-suited for FPGA mezzanine applications requiring 112 signal lines, supporting differential pair routing with minimal skew when signals are matched in the layout.
Does the -TR suffix mean the SFM-128-T2-L-D-A-K-TR ships on tape-and-reel for production use?
Yes, the -TR suffix confirms tape-and-reel packaging with standard 8 mm or 12 mm carrier tape, enabling automated SMT pick-and-place equipment to handle the part efficiently at production volumes typically starting at 1000 pieces per reel.
What is the advantage of surface-mount termination over through-hole in the SFM-128-T2-L-D-A-K-TR?
Surface-mount termination eliminates the need for 112 drilled through-holes, reducing PCB fabrication cost, supporting finer via pitch on inner layers, and allowing component placement on both sides of the board for higher integration density.
