What are the key features of SFM-118-02-LM-D-LC?
- 36-position dual-row socket strip at 1.27 mm (0.050 inch) pitch delivers high-density SMT interconnect in half the footprint of standard 2.54 mm connectors
- Low-profile LM contact design minimizes stack height, enabling thin system architectures in embedded and portable electronics
- Lead-free (LC) construction with gold-plated contacts meets RoHS compliance requirements and ensures low contact resistance across mating cycles
What is SFM-118-02-LM-D-LC used for?
The SFM-118-02-LM-D-LC is designed for high-density, low-profile board-to-board and mezzanine interconnect applications in portable medical devices, compact embedded systems, and communication modules. Its 1.27 mm pitch socket strip allows engineers to route 36 signals in a footprint substantially smaller than traditional 2.54 mm alternatives, supporting miniaturized product designs. The lead-free RoHS-compliant construction makes it suitable for consumer electronics, industrial IoT endpoints, and green-compliance-mandated programs.

Frequently Asked Questions
What pitch does SFM-118-02-LM-D-LC use and how does the dual-row layout benefit high-density designs?
The SFM-118-02-LM-D-LC uses a 1.27 mm (0.050 inch) pitch in a dual-row layout, providing 36 positions with 18 contacts per row. Compared to a single-row 2.54 mm connector carrying the same signal count, the dual-row 1.27 mm format reduces the connector's PCB length by approximately 75%, freeing significant board space in space-constrained embedded and portable designs.
What does the LC suffix mean on SFM-118-02-LM-D-LC and does it affect soldering compatibility?
The LC suffix denotes lead-free construction, meaning the SFM-118-02-LM-D-LC uses a lead-free solder-compatible finish on its terminations and contacts. This ensures compliance with RoHS Directive requirements and compatibility with SAC305 or similar lead-free solder alloys used at standard reflow peak temperatures of 245°C to 260°C in SMT assembly.
What contact style does the LM designation indicate on SFM-118-02-LM-D-LC?
The LM designation specifies a low-profile mount contact style, which reduces the overall connector stack height compared to standard-height SFM variants. This low-profile geometry is critical in thin portable devices and mezzanine module designs where total system height must remain below a defined threshold, often 5 mm or less above the PCB surface.
In which application categories is SFM-118-02-LM-D-LC a preferred choice over standard pitch connectors?
SFM-118-02-LM-D-LC is preferred in portable medical monitors, wearable electronics, compact industrial IoT modules, and communications daughter cards where both 36-signal capacity and minimum PCB footprint are required simultaneously. Its 1.27 mm pitch socket provides roughly 50% linear density improvement over 2.54 mm alternatives, and the lead-free gold-plated contacts support hundreds of mating cycles at operating temperatures from -55°C to +125°C.
