Key Features
- 18-position dual-row SMT socket strip at 0.050" (1.27 mm) pitch enabling high-density board-to-board connections in compact assemblies
- Gold-plated contacts (K suffix) maintain contact resistance below 20 mΩ across repeated mating cycles for long-term reliability
- Tape-and-reel (TR) format and SMT attachment are optimized for automated pick-and-place reflow soldering in high-volume production
Applications
The SFM-109-T2-FM-D-A-K-TR is designed for mezzanine board connections, small form-factor module stacking, and fine-pitch expansion interfaces in embedded computing, telecom, and instrumentation. Its 18-position 0.050" pitch dual-row configuration suits memory module sockets, FPGA mezzanine cards, and compact I/O expansion designs where board space is tightly constrained. The tape-and-reel packaging ensures compatibility with automated SMT production environments.

Frequently Asked Questions
How many contacts does SFM-109-T2-FM-D-A-K-TR provide and at what pitch?
SFM-109-T2-FM-D-A-K-TR provides 18 total positions in a dual-row arrangement at 0.050" (1.27 mm) pitch, with 9 contacts per row. This fine-pitch configuration allows high contact density within a minimal PCB footprint, suitable for compact modules requiring 18 simultaneous electrical connections in telecom, embedded computing, or instrumentation applications.
For compact mezzanine card designs, how does SFM-109-T2-FM-D-A-K-TR compare to 0.100" pitch alternatives?
SFM-109-T2-FM-D-A-K-TR at 0.050" (1.27 mm) pitch occupies approximately half the linear PCB space of a 0.100" pitch socket carrying the same 18 contacts. This makes it the preferred choice when board area is below 10 mm wide, as in FPGA mezzanine cards or small form-factor embedded modules where 0.100" pitch alternatives would exceed available land patterns.
What mating connector family is compatible with SFM-109-T2-FM-D-A-K-TR?
SFM-109-T2-FM-D-A-K-TR mates with SAMTEC's TSM series terminal strip headers at 0.050" pitch, creating a board-to-board stacking pair. The socket accepts 0.025" square-post headers with a standard 0.050" (1.27 mm) pin grid, enabling stacking heights from 3 mm to over 20 mm depending on the selected header style, providing design flexibility for varied board separation requirements.
