What are the key features of SFM-107-L2-SM-D-K-TR?
- 14-position dual-row socket on 0.050 inch (1.27 mm) pitch providing high-density signal routing in a minimal PCB footprint
- L2 extended tail variant offering additional solder post length for improved solder joint clearance and inspection access
- High-reliability gold-plated contacts maintaining low contact resistance below 20 mΩ across repeated mating cycles for test and production use
- Tape-and-reel (TR) packaging enabling automated pick-and-place SMT assembly for high-volume manufacturing lines
What is SFM-107-L2-SM-D-K-TR used for?
The SFM-107-L2-SM-D-K-TR suits low pin-count mezzanine and expansion board designs where 14 signals must bridge two stacked PCBs on a 0.050 inch pitch, saving board area compared to standard 0.100 inch alternatives. The L2 extended tail variant is especially useful in RF and high-speed digital boards where solder joint height must be controlled for impedance management or optical solder inspection clearance. Embedded module interconnects, FPGA expansion sockets, and small form-factor test adapters that require frequent mating cycles are typical application targets.

Frequently Asked Questions
What does the L2 tail designation on the SFM-107-L2-SM-D-K-TR indicate, and how does it affect PCB solder joint design?
The L2 designation specifies an extended SMT tail length compared to the standard tail, providing additional solder paste contact area and raising the connector body slightly above the PCB surface. This extra clearance—typically around 1.5 mm to 2 mm—improves automated optical inspection access under the connector body and can help manage solder bridging risk on fine 0.050 inch pitch pads.
How many signal contacts does the SFM-107-L2-SM-D-K-TR support, and which low pin-count module standards does this suit?
The SFM-107-L2-SM-D-K-TR provides 14 contacts in a dual-row layout, making it suitable for small FPGA configuration headers, SPI and UART expansion sockets, and compact sensor-module interfaces that require 14 or fewer signal lines. Its 0.050 inch pitch also matches the SFM-series mating plug family, enabling direct compatibility with SAMTEC SFM plug strips.
Is the SFM-107-L2-SM-D-K-TR compatible with standard lead-free reflow soldering, and what peak temperature applies?
Yes, the SFM-107-L2-SM-D-K-TR is compatible with lead-free reflow soldering processes following JEDEC J-STD-020, with a maximum reflow peak temperature of approximately 260°C. Its tape-and-reel format supports automated SMT pick-and-place, and the land pattern follows IPC-7351 guidelines for 0.050 inch pitch fine-pitch SMT connectors.
When upgrading a board from 0.100 inch pitch connectors to 0.050 inch pitch SFM connectors, what routing advantages does the SFM-107-L2-SM-D-K-TR offer?
Switching to the 0.050 inch pitch SFM-107-L2-SM-D-K-TR reduces the linear connector length for 14 contacts by approximately 50% compared to an equivalent 0.100 inch connector, freeing board edge space for additional circuitry or reducing overall PCB size. The dual-row arrangement further shortens the length, and the finer pitch fanout traces can be routed on fewer PCB layers in designs with 100 µm or finer design rules.
