Key Features
- 36-position dual-row surface mount configuration at 0.050" (1.27 mm) pitch for compact high-density PCB signal routing
- Gold-plated contacts rated at 1 A per pin ensuring low contact resistance and reliable performance over extended mating cycles
- High-reliability design with operating temperature range of -55°C to +125°C suitable for industrial and harsh-environment applications
- LC (low-cost) packaging option providing an economical procurement path compared to tape-and-reel formats for prototype and low-volume builds
Applications
The SFM-118-02-F-D-LC is used in board-to-board and mezzanine interconnect designs where a 36-pin dual-row 0.050" pitch socket is required in a small SMT footprint. It suits test and measurement equipment, embedded computing modules, and industrial I/O expansion boards that need compact yet reliable connector solutions. Its broad -55°C to +125°C temperature rating also makes it appropriate for automotive peripherals and defense electronics applications.

Frequently Asked Questions
How many positions does SFM-118-02-F-D-LC have, and how is the dual-row layout structured at 0.050" pitch?
The SFM-118-02-F-D-LC has 36 total positions arranged in 2 rows of 18, with a 0.050" (1.27 mm) centerline pitch. This dual-row configuration at fine pitch provides 36 signal connections in a very compact PCB footprint. The 1.27 mm pitch is half that of standard 0.100" connectors, allowing higher connectivity density for space-constrained embedded board designs where routing 36 lines through a standard pitch connector would require excessive PCB area.
What does the LC suffix in SFM-118-02-F-D-LC mean, and how does it compare to tape-and-reel packaging for procurement?
The LC suffix designates a loose or low-cost packaging format, meaning connectors are shipped in bags or trays rather than tape-and-reel. This makes the SFM-118-02-F-D-LC more economical for prototype builds, engineering samples, or low-volume production where automated pick-and-place assembly is not required. For high-volume SMT production runs exceeding hundreds of units, engineers typically switch to the tape-and-reel variant (TR suffix) to support automated feeder equipment and reduce per-unit handling cost.
What is the current rating per contact and operating temperature range of the SFM-118-02-F-D-LC for industrial designs?
Each contact in the SFM-118-02-F-D-LC is rated for 1 A continuous current, which is adequate for signal lines and low-current power rails in typical board-to-board applications. The connector is rated across an operating temperature range of -55°C to +125°C, meeting the demands of industrial control environments, telecommunications hardware, and even defense-grade boards subject to extreme thermal conditions. Gold-plated contact surfaces maintain stable contact resistance throughout this temperature range and across many mating cycles.
Which Samtec header series mates with SFM-118-02-F-D-LC for a complete 36-position 0.050" dual-row board-to-board stack?
The SFM-118-02-F-D-LC socket mates with Samtec's 0.050" pitch dual-row plug headers such as the TSM-118 or equivalent SMM series, creating a complete 36-position mezzanine interconnect at 1.27 mm pitch. Stack height between the two mating boards is determined by the plug header height selected, typically ranging from about 4 mm to 20 mm. Both halves are available with the LC or TR packaging suffix, allowing engineers to match packaging choices on both the socket and plug for their production volume.
