What are the key features of SFM-125-L2-H-D-A-K?
- 50-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch providing 25 contacts per row for high-density mezzanine and expansion interconnects
- Elevated (H) housing height increases mating clearance to accommodate taller components between stacked boards in constrained assemblies
- Gold-plated contacts (K suffix) ensure contact resistance below 20 mΩ and extended reliability across hundreds of mating cycles in demanding environments
What is SFM-125-L2-H-D-A-K used for?
The SFM-125-L2-H-D-A-K is suited for high-density mezzanine board stacking, FPGA expansion cards, and modular embedded systems where 50 contacts at 0.050" pitch must bridge boards with larger inter-board clearance. Its elevated housing height accommodates taller surface-mount components mounted between the stacked boards, a key requirement for telecom line cards and advanced data acquisition platforms. Gold-plated contacts ensure long-term electrical stability in both commercial and industrial temperature environments.

Frequently Asked Questions
Which connector role does SFM-125-L2-H-D-A-K fill?
SFM-125-L2-H-D-A-K is a high-reliability socket strip for board stacking, using 50 contacts across 2 rows on a 1.27 mm pitch.
How can a layout team confirm this part fits the board?
Verify the land pattern supports 50 SMT contacts, a 1.27 mm pitch, and the elevated body height required by the mating board clearance.
Which replacement checks reduce sourcing risk?
Before approving an alternate, compare the 50-position count, 2-row orientation, contact plating, and 1.27 mm pitch against the approved SAMTEC drawing.
What production details should be checked before assembly release?
Confirm pick-and-place data for all 50 contacts, review reflow limits from the datasheet, and ensure the 1.27 mm connector spacing matches inspection criteria.
