Key Features
- 16-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch, delivering high contact density in a compact 0.555" body length
- 30 micro-inch gold (Au) contact finish on phosphor bronze or beryllium copper spring contacts for low contact resistance and extended cycle life
- RoHS-compliant (Pb-free) construction supporting modern green manufacturing and regulatory compliance in industrial and commercial designs
Applications
The SFM-108-02-H-D is well suited for board-to-board socket connections in compact embedded computing modules, high-speed mezzanine cards, and test instrumentation daughterboards that require 16 signals at 0.050" pitch. Its phosphor bronze or beryllium copper contacts with 30 micro-inch gold plating ensure consistent mating force and signal integrity across hundreds of engagement cycles in laboratory and field-deployed equipment.

Frequently Asked Questions
What spring contact material and gold plating thickness does the SFM-108-02-H-D specify, and how does that affect long-term reliability?
The SFM-108-02-H-D uses phosphor bronze or beryllium copper spring contacts with a 30 micro-inch gold (Au) mating finish. The 30 micro-inch gold layer resists oxidation and maintains stable contact resistance across hundreds to thousands of mating cycles, making it appropriate for high-reliability socket applications in industrial controls and test fixtures.
How many signal positions and what pitch does the SFM-108-02-H-D support, and what board area does it occupy?
The SFM-108-02-H-D provides 16 positions in a dual-row layout at 0.050" (1.27 mm) pitch. The connector body measures 0.555" in length, 0.145" in breadth, and 0.185" in depth, so each row carries 8 female contacts within a footprint that fits easily on compact PCBs where a full 0.100" pitch strip would consume twice the board area.
Is the SFM-108-02-H-D compatible with RoHS requirements, and what does the Pb-free designation mean for the manufacturing process?
Yes, the SFM-108-02-H-D carries a Pb-free code, confirming RoHS compliance. The Pb-free designation means the termination finish and connector materials meet EU RoHS restrictions on hazardous substances, allowing the part to be soldered using lead-free SAC solder alloys in standard SMT reflow ovens at temperatures typically reaching 250 to 260 degrees Celsius.
For a mezzanine board stack using SFM-108-02-H-D sockets, what mating headers at 0.050" pitch are appropriate?
The SFM-108-02-H-D is designed to accept SAMTEC's TSM or SSM series 0.050" pitch male headers, or equivalent 0.050" dual-row square-pin headers from compatible vendors. The female socket contacts at 16 positions accommodate the mating male pins and provide the spring force needed for reliable electrical contact in board-stacking configurations used in FPGA modules, processor cards, and measurement instruments.
