Key Features
- 10-position dual-row 1.27 mm pitch SMT socket strip enables high-density fine-pitch board-to-board interconnection in space-constrained designs
- High-reliability construction rated for 500 mating cycles with gold-plated contacts maintaining contact resistance below 30 mΩ
- Low-profile surface-mount form factor supports tight stack height requirements in layered PCB assemblies and mezzanine board configurations
Applications
The SFM-105-L2-SM-D-A-K is used in FPGA mezzanine modules, RF daughterboard assemblies, and compact embedded computing stacks where a 10-position 1.27 mm pitch dual-row SMT socket provides high-reliability fine-pitch board-to-board connectivity in a minimal footprint. It is also found in high-cycle test fixtures and instrumentation daughterboards where 500-cycle-rated gold contacts maintain stable contact resistance across -55°C to 125°C operating conditions.

Frequently Asked Questions
What pitch and position count does SFM-105-L2-SM-D-A-K offer for board-to-board connections?
The SFM-105-L2-SM-D-A-K provides 10 positions in a dual-row (2×5) configuration with 1.27 mm (0.050 inch) pitch between adjacent contacts, enabling high-density fine-pitch interconnection in a total footprint of approximately 7.62 mm × 2.54 mm for compact mezzanine and daughterboard stacking applications.
How many mating cycles can SFM-105-L2-SM-D-A-K withstand in high-cycle test environments?
The SFM-105-L2-SM-D-A-K is rated for 500 mating cycles with contact resistance maintained below 30 mΩ throughout its service life, which supports repeated module swaps in test-and-measurement fixtures, JTAG debug adapters, and field-replaceable sensor modules where connectors are engaged multiple times daily.
Which SAMTEC mating headers are compatible with SFM-105-L2-SM-D-A-K for a stacked PCB assembly?
The SFM-105-L2-SM-D-A-K mates with SAMTEC SHF and SFM series headers that share the same 1.27 mm pitch and dual-row layout, allowing designers to choose a matching 10-position plug with stack heights from 4 mm to over 20 mm depending on component clearance requirements between the two PCBs in the assembly.
What temperature range does SFM-105-L2-SM-D-A-K support for industrial mezzanine applications?
The SFM-105-L2-SM-D-A-K operates across -55°C to 125°C, spanning standard industrial and military screening temperature ranges, so it can be used in rugged embedded computing platforms, avionics test interfaces, and industrial sensor hubs where operating temperatures fluctuate well below 0°C in winter storage and spike to 125°C during peak thermal load events.
