What are the key features of SFM-104-L2-F-D-LC?
- 8 positions in dual-row 0.050-inch pitch SMT layout for ultra-compact board-to-board mezzanine connections
- L2 tail length optimized for precise SMT pad engagement and reliable reflow solder joint formation
- High-reliability gold-plated contacts ensure consistent mating performance across multiple insertion cycles
- Dual-row 4-per-row configuration delivers 8 signal channels in a 0.2-inch PCB footprint length
- LC (lead-cut) termination option provides flush solder tails for low-profile SMT assembly
What is SFM-104-L2-F-D-LC used for?
The SFM-104-L2-F-D-LC is designed for ultra-compact mezzanine connections in small-form-factor embedded modules, wearable sensor nodes, and miniature IoT devices requiring 8 dual-row signal channels at 0.050-inch pitch. Its minimal 0.2-inch footprint and lead-cut termination make it ideal for medical wearables, micro-controller daughter boards, and compact FPGA expansion headers where PCB real estate is extremely limited.

Frequently Asked Questions
With only 8 positions, what design scenarios favor the SFM-104-L2-F-D-LC over a larger connector from the same series?
An 8-position dual-row socket at 0.050-inch pitch is chosen when the interface requires 8 or fewer signal channels and PCB space is at a premium — for example, a small SPI or I2C expansion header on a wearable medical sensor node where the total connector footprint must stay within 0.2 inches in length. Using a smaller 8-position socket rather than a 20- or 40-position connector also reduces assembly cost and eliminates unused contact positions that could add capacitive loading to signal lines.
What does the LC (lead-cut) termination mean for PCB assembly of SFM-104-L2-F-D-LC?
The LC designation indicates that the solder tails are trimmed flush with the connector body bottom, producing a low-profile SMT footprint with no protruding leads beneath the PCB. This lead-cut termination is essential for assemblies where bottom clearance is less than 1 mm, such as stacked boards in wearable devices or embedded modules where the 8-position dual-row socket must sit flat against the PCB surface without risk of shorting to an adjacent copper feature below.
How does the 8-position SFM-104-L2-F-D-LC compare to a single-row 8-position socket at 0.100-inch pitch for a compact sensor interface?
The dual-row 0.050-inch pitch SFM-104 packs 8 contacts into a footprint of approximately 0.2 inches by 0.1 inches, compared to a single-row 0.100-inch pitch socket that would span 0.7 inches for 8 positions. This represents roughly a 70% reduction in connector length, allowing the SFM-104-L2-F-D-LC to fit on miniature PCBs under 15 mm in dimension while still providing 8 reliable signal channels with gold-plated contact finishes.
What mating header from SAMTEC pairs with SFM-104-L2-F-D-LC for a complete 8-position board-to-board stack?
The SFM-104-L2-F-D-LC mates with SAMTEC TSM or TFM dual-row headers at 0.050-inch pitch offering 8 positions (4 per row), completing an 8-contact board-to-board connection with typical mated stack heights ranging from 4 mm to 15 mm depending on the selected header standoff length. Contact resistance in the mated pair is typically below 20 milliohms per contact, suitable for both signal and low-current power distribution across the 8-position interface.
