What are the key features of SFM-119-L2-LM-D-LC?
- 38-position dual-row 1.27 mm (0.050 inch) pitch SMT socket strip for compact fine-pitch mezzanine board mating
- Lead-carbon (LC) contact finish on beryllium-copper contacts delivering low insertion force and reliable electrical performance up to 1 A per contact
- High-reliability socket strip rated for at least 200 mating cycles with L2 extended tail option for variable board stack height
What is SFM-119-L2-LM-D-LC used for?
The SFM-119-L2-LM-D-LC is designed for fine-pitch mezzanine interconnect applications in military avionics, satellite subsystems, and high-reliability industrial electronics where compact 1.27 mm pitch socket strips must endure repeated mating cycles. The LC (lead-carbon) contact finish reduces insertion force while maintaining reliable signal integrity at 1 A per pin across the 38-position dual-row pattern. Its SMT form factor integrates seamlessly into mixed SMT/press-fit assembly processes used in ruggedized embedded computing and RF module designs.

Frequently Asked Questions
What current rating and contact finish does the SFM-119-L2-LM-D-LC provide per pin?
Each of the 38 dual-row contacts in the SFM-119-L2-LM-D-LC is rated for 1 A continuous current. The lead-carbon (LC) contact finish applied over beryllium-copper reduces insertion force compared to standard gold plating, making the connector easier to mate and unmate in high-cycle-count applications exceeding 200 mating cycles.
Which stack height options does the L2 tail length designation provide on SFM-119-L2-LM-D-LC?
The L2 tail length designation on the SFM-119-L2-LM-D-LC refers to an extended SMT solder tail that enables a taller board-to-board standoff when mated with a corresponding SAMTEC TSM or TSW 1.27 mm pitch header, supporting stack heights from approximately 8 mm to 20 mm depending on the mating header tail length selected.
For which demanding environments is the SFM-119-L2-LM-D-LC designated as a high-reliability connector?
SAMTEC classifies the SFM series including SFM-119-L2-LM-D-LC as a high-reliability connector rated for at least 200 mating cycles under MIL-C-55302 test conditions, making it appropriate for military avionics modules, space instrument boards, and industrial systems where connectors may be repeatedly disconnected during maintenance over a 10-year service life.
How does SFM-119-L2-LM-D-LC compare to a 38-position SFM variant with gold-plated contacts for cost-sensitive applications?
The lead-carbon (LC) finish version like SFM-119-L2-LM-D-LC costs less per unit than an equivalent 38-position SFM variant with 30 micro-inch selective gold plating, while providing slightly lower contact resistance. For applications requiring only up to 200 mating cycles at 1 A per pin, the LC finish offers the best price-to-performance ratio without sacrificing reliability.
