Key Features
- 36-position dual-row configuration at 0.050" (1.27 mm) pitch for compact high-density SMT board-to-board interconnection
- Polarization peg (-P) prevents mis-mating during assembly, improving reliability in 18-position-per-row dual-row connector systems
- Elevated (-H) height profile accommodates component clearance under mezzanine boards in stacked PCB assemblies
Applications
The SFM-118-L2-H-D-A-P is used in mezzanine card assemblies, FPGA daughter cards, and industrial control module stacks requiring a polarized 36-position 1.27 mm pitch SMT socket. Its elevated height option provides component clearance beneath the upper board, making it well suited for DSP evaluation modules, RF front-end stacking, and test fixture interconnections.

Frequently Asked Questions
How does the polarization peg on the SFM-118-L2-H-D-A-P prevent assembly errors?
The -P suffix on the SFM-118-L2-H-D-A-P indicates a polarization peg that physically prevents reversed or mis-aligned mating. In 36-position dual-row 1.27 mm pitch applications, this peg ensures the mating header inserts only in the correct orientation, reducing rework rates in high-volume SMT assembly.
What elevated height does the SFM-118-L2-H-D-A-P provide and why does it matter for stacked PCB designs?
The -H designation in the SFM-118-L2-H-D-A-P specifies an elevated connector body that creates clearance between two stacked boards, typically 8 mm to 11 mm above-board height. This clearance allows tall SMT components such as capacitors, oscillators, or RF shielding cans up to several millimeters high to be placed on the lower board without interference.
Which SAMTEC mating plug families are compatible with the SFM-118-L2-H-D-A-P?
The SFM-118-L2-H-D-A-P is designed to mate with SAMTEC TSM-118 or SFM-118 series plugs at 1.27 mm pitch with 36 positions in a dual-row arrangement. SAMTEC application data confirms these SFM series sockets deliver a mating cycle life of at least 30 times and contact resistance below 20 mOhm per pin.
In what types of FPGA or DSP development boards is the SFM-118-L2-H-D-A-P commonly specified?
FPGA evaluation boards, DSP co-processor daughter cards, and high-speed analog front-end modules frequently use the SFM-118-L2-H-D-A-P for its compact 1.27 mm pitch 36-position footprint. The polarization peg and elevated profile allow designers to safely stack expansion cards carrying ADC or DAC modules operating at signal rates above 100 MHz.
