What are the key features of SFM-119-T2-LM-D-A-K-TR?
- 38-position dual-row socket strip at 0.050-inch (1.27 mm) pitch providing compact high-density board-to-board interconnect
- High-reliability design with K-option locking retention for secure mating under mechanical shock and vibration
- Tape-and-reel (TR) packaging supporting automated SMT pick-and-place assembly for high-volume production
What is SFM-119-T2-LM-D-A-K-TR used for?
The SFM-119-T2-LM-D-A-K-TR is used in mezzanine and daughter-card interconnect designs where 38 dual-row contacts at 0.050-inch pitch maximize signal density in constrained PCB areas. Its surface-mount construction is well-suited for communications, computing, and embedded control platforms requiring robust board-stacking with controlled impedance traces. Engineers also specify it for FPGA evaluation boards, radar modules, and mil-aero daughter cards where locking retention prevents unmating under vibration or shock.

Frequently Asked Questions
How many contact positions does the SFM-119-T2-LM-D-A-K-TR provide, and how does the dual-row layout maximize signal density?
The SFM-119-T2-LM-D-A-K-TR provides 38 total positions arranged in 2 rows of 19 contacts each at a 0.050-inch (1.27 mm) pitch. This dual-row layout doubles the contact density compared to a single-row socket of the same footprint length, enabling 38 signal or power lines to pass between two PCBs within a board area under 30 mm wide.
Does the locking (K) option in SFM-119-T2-LM-D-A-K-TR maintain mating integrity when subject to 10 G vibration in a mil-aero application?
The K (locking) option adds a mechanical retention feature that resists accidental unmating under shock and vibration. For mil-aero daughter cards exposed to 10 G vibration profiles per MIL-STD-810, this locking engagement reduces the risk of intermittent contact and eliminates the need for secondary mechanical restraints such as screws or clips.
What tape-and-reel quantity is typically available for SFM-119-T2-LM-D-A-K-TR, and does it support 5,000-unit production builds?
SAMTEC supplies the SFM-119-T2-LM-D-A-K-TR on standard tape-and-reel carriers, with full reels typically containing several hundred to over 1,000 pieces per reel depending on part width. A 5,000-unit production build can be fulfilled by ordering multiple reels through authorized distributors, and the TR packaging format is directly compatible with standard SMT pick-and-place machines at 0.050-inch pitch component feeders.
Which mating header from SAMTEC pairs with SFM-119-T2-LM-D-A-K-TR to set a 6 mm board-stacking height?
SAMTEC SHF or TFM series headers at the same 0.050-inch (1.27 mm) pitch mate with the SFM-119 socket strip. Selecting a header with a 6 mm post length and appropriate solder tail geometry achieves a 6 mm board separation, though designers should consult the SAMTEC stack-height selection guide to confirm the exact header variant (such as TFM-119-L2-LM-D) that delivers the 6 mm standoff in their specific assembly.
