What are the key features of SFM-128-02-H-D-DS?

  • 56-position dual-row socket on 1.27 mm (0.050 inch) pitch offering high signal density in a compact surface mount footprint
  • H-height tall body provides increased vertical board-to-board clearance to accommodate tall passive components or through-hole parts between stacked PCBs
  • DS (dual slot) contact system enhances mechanical retention and contact reliability through redundant wiping points across all 56 positions

What is SFM-128-02-H-D-DS used for?

The SFM-128-02-H-D-DS is designed for high-pin-count mezzanine applications in FPGA evaluation boards, data acquisition daughter cards, and high-performance computing modules requiring 56 positions at 1.27 mm pitch. The H-height option provides sufficient vertical clearance for tall passives or shielding structures mounted on the host PCB beneath the daughter board. The DS dual-slot contact design increases mating robustness, making this socket suitable for field-replaceable modules subject to repeated board insertions.

Frequently Asked Questions

How does SFM-128-02-H-D-DS support dense mezzanine board layouts?

Its dual-row socket arrangement provides 56 pins at 1.27 mm pitch, enabling a compact mezzanine connection while the H-height option provides additional vertical clearance.

Which assembly checks matter before this connector enters SMT production?

Confirm the footprint for all 56 pins, mating orientation, standoff height, solder-pad geometry, and the DS contact configuration against the SAMTEC drawing before releasing the board.

When evaluating a substitute, which ordering details should procurement preserve?

A compatible substitute must retain 56 pins, the 1.27 mm pitch, dual-row surface-mount termination, matching stack height, and equivalent contact and plating options for reliable mating.
