What are the key features of SFM-129-02-H-D-K-TR?
- 58-position dual-row SMT socket at 0.050 inch (1.27 mm) pitch delivering very high contact density for complex board-to-board signal interconnect
- High-profile (-H) mated height variant providing increased board-to-board clearance for components taller than 4 mm on the mezzanine PCB
- High-reliability SFM contact design rated for extended mating cycles with contact resistance remaining under 30 milliohms throughout service life
- Tape-and-reel (-TR) packaging enabling automated SMT pick-and-place assembly to support high-volume manufacturing throughput
What is SFM-129-02-H-D-K-TR used for?
The SFM-129-02-H-D-K-TR is used in high-density mezzanine stacking applications in embedded computing, FPGA development boards, and industrial control modules where 58 signals need reliable routing between two stacked PCBs. Its high-profile mated height provides additional board-to-board clearance that accommodates through-hole components, large capacitors, or heat sinks on the mezzanine card surface. The tape-and-reel format supports seamless integration into automated assembly lines for volume production of communications and defense electronics.

Frequently Asked Questions
How many positions does the SFM-129-02-H-D-K-TR offer and how are they distributed between rows?
The SFM-129-02-H-D-K-TR provides 58 positions arranged in a dual-row layout with 29 contacts per row at 0.050 inch (1.27 mm) pitch. This gives a connector body length of approximately 37 mm, allowing simultaneous routing of 58 independent signal or power connections between two mated PCBs. The dual-row layout improves routing efficiency over single-row alternatives, supporting address buses, data buses, control lines, and multiple power rails within a single connector.
What board-to-board clearance does the high-profile (-H) mated height designation provide and when is it necessary?
The -H designation indicates a high-profile mated height, typically providing 8 mm to 12 mm of board-to-board clearance between the two mated PCB surfaces. This extra clearance is needed when the mezzanine PCB carries tall components such as electrolytic capacitors over 6 mm high, heat sinks, or through-hole connectors that would otherwise collide with the baseboard. Compared to a standard or low-profile variant at 2 mm to 4 mm clearance, the high-profile version adds stacking height but prevents mechanical interference in complex sub-assembly designs.
For a defense electronics module requiring 58 board-to-board connections, how does the SFM-129 high-reliability rating support long service life?
SAMTEC's SFM-series high-reliability socket strips are engineered for extended mating cycle endurance, rated for a minimum of 200 mating cycles with contact resistance maintained below 30 milliohms throughout. In defense electronics where modules may be inserted and removed for field maintenance dozens of times per year over a 10-year service life, this rating covers over 2,000 cumulative cycles on a single socket. The 58-position SFM-129-02-H-D-K-TR also meets environmental robustness requirements common to MIL-STD adjacent commercial programs.
Can the SFM-129-02-H-D-K-TR be sourced in cut-tape for prototype quantities or is it reel-only?
While the SFM-129-02-H-D-K-TR is packaged in tape-and-reel (-TR) format with standard reel quantities of 500 to 1,000 pieces, SAMTEC and its authorized distributors typically offer cut-tape samples in quantities as low as 1 to 10 pieces for engineering prototypes and design evaluation. Engineers can request samples directly from SAMTEC's website or order cut-tape through distributors. Full reel quantities are required for production builds, but prototype access is well-supported without committing to a full reel.
