What are the key features of SFM-103-02-F-D-LC-TR?
- 6-position dual-row socket at 0.050" (1.27 mm) pitch in a compact SMT footprint suitable for space-critical PCB designs requiring minimal real estate
- Floating (F) contact design accommodates up to ±0.5 mm PCB-to-PCB misalignment during mating, reducing insertion stress on solder joints
- Tape-and-reel (TR) packaging supports fully automated pick-and-place and SMT reflow assembly for high-volume PCB production
- Gold-plated contacts with LC retention provide reliable low-contact-resistance connections in demanding industrial and defense applications
What is SFM-103-02-F-D-LC-TR used for?
The SFM-103-02-F-D-LC-TR is well-suited for compact board-to-board and module-to-mainboard interconnect applications where only 6 signal channels are needed at 1.27 mm pitch, such as sensor interface modules, small plug-in peripherals, and configuration or programming headers. The floating contact design is especially useful in manually assembled or chassis-mounted systems where precise PCB alignment is difficult to achieve. Tape-and-reel packaging makes this 6-position socket practical for high-volume automated SMT production in industrial, medical, and communications electronics.

Frequently Asked Questions
What is the pin count and pitch of the SFM-103-02-F-D-LC-TR, and what types of interfaces does it serve?
The SFM-103-02-F-D-LC-TR has 6 positions in a dual-row format (3 per row) at 0.050" (1.27 mm) pitch. This compact size is ideal for low-channel-count board-to-board interfaces such as 4-wire SPI buses with power and ground, I2C sensor module connections, or 6-signal programming and debug headers on compact embedded PCBs.
How does the floating (F) contact feature of the SFM-103-02-F-D-LC-TR reduce PCB assembly risk?
The floating (F) contact design allows the mating header to self-align within a tolerance of approximately ±0.5 mm during insertion, absorbing minor PCB-to-PCB offset that would otherwise apply bending stress to the surface mount solder joints. For small 6-position connectors on thin PCBs, this prevents pad lifting or joint cracking, especially in chassis-mounted or field-replaceable module applications.
When should a designer choose the SFM-103-02-F-D-LC-TR over a larger SFM-series connector for a small module interface?
When only 6 signal channels are needed — for example, a 4-bit data bus with power and ground, or a 6-line control interface — the SFM-103-02-F-D-LC-TR provides the smallest possible dual-row footprint at 0.050" (1.27 mm) pitch, occupying just 3 pin positions per row. Using a larger connector in this case wastes PCB space and adds unnecessary cost, while this 6-position variant meets the signal count requirement with a minimal 0.150" (3.81 mm) total row width.
What production benefits does the tape-and-reel packaging of the SFM-103-02-F-D-LC-TR provide for SMT manufacturing?
The -TR suffix indicates tape-and-reel packaging, enabling automated pick-and-place machines to handle the 6-position socket without operator involvement. This is particularly advantageous in high-volume runs where consistent placement accuracy for a small 1.27 mm pitch dual-row connector is critical. The SMT pads support standard lead-free reflow profiles, and the component can be processed alongside other SMD parts in a single pass through the reflow oven.
