What are the key features of SFM-103-L2-L-D?

6-position dual-row SMT socket strip on 1.27 mm (0.050 inch) pitch with a compact body measuring only 7.75 mm x 4.70 mm x 3.73 mm
10 µin gold mating contact finish over nickel barrier ensures reliable low-resistance connections across hundreds of mating cycles in compact module designs
Tin-over-nickel (Sn/Ni) termination finish is optimized for lead-free reflow soldering at 245°C peak, ensuring RoHS-compliant solder joint integrity

What is SFM-103-L2-L-D used for?

The SFM-103-L2-L-D is suited for micro-module daughter-card interfaces, sensor breakout boards, and compact wireless module sockets where only 6 connections are needed in a minimal SMT footprint. Its 1.27 mm pitch fits naturally on space-constrained designs such as IoT edge nodes, portable medical sensors, and compact camera interface boards.

Frequently Asked Questions

How compact is the SFM-103-L2-L-D body, and how does its size affect PCB placement?

The SFM-103-L2-L-D body measures approximately 7.75 mm long by 4.70 mm wide by 3.73 mm tall, housing 6 contacts in a dual-row layout on a 1.27 mm pitch. This small footprint occupies less than 36 mm² of PCB area, making it practical for sensor node boards where multiple connectors must coexist within a 20 mm × 20 mm module area.

What contact finish does the SFM-103-L2-L-D use, and how many mating cycles does it support?

The mating contacts carry 10 µin (microinch) gold over nickel, while the termination contacts use tin over a nickel diffusion barrier. The 10 µin gold finish supports at least 100 mating cycles with contact resistance remaining below 30 mΩ, meeting requirements for socketed module applications that require periodic removal for firmware updates or replacement.

Is SFM-103-L2-L-D a suitable socket for mating with SAMTEC TMS-103 or TMM-103 pin headers?

Yes. The SFM series on 1.27 mm pitch is designed to mate with SAMTEC TMS and TMM 2-row pin header families sharing the same 1.27 mm grid. A 6-position SFM-103 socket accepts a TMS-103 or TMM-103 header with approximately 0.2 N per-contact normal force, totaling about 1.2 N insertion force across all 6 pins, which is easily managed by hand or automated insertion.
