What are the key features of SFM-109-02-L-D-A-K-TR?
- 18-position dual-row socket strip on 1.27 mm (0.050 inch) fine pitch for maximum signal density per unit PCB area
- High-reliability contact design rated for extended mating cycles exceeding 200 insertions without degradation
- Low-profile (L suffix) SMT socket minimizes component height above PCB surface for compact system designs
- Tape-and-reel (TR) packaging enables fully automated SMT pick-and-place assembly in high-volume production
What is SFM-109-02-L-D-A-K-TR used for?
The SFM-109-02-L-D-A-K-TR is designed for high-density board-to-board interconnect in compact embedded computing, FPGA expansion cards, and portable instrumentation. Its 18-position dual-row 0.050 inch pitch layout allows 18 signal connections in a very small PCB footprint, enabling miniaturized system designs. The high-reliability contacts and tape-and-reel packaging make it well suited for high-volume medical device and communication hardware manufacturing.

Frequently Asked Questions
What pitch and position count does the SFM-109-02-L-D-A-K-TR offer for board-to-board signal routing?
The SFM-109-02-L-D-A-K-TR provides 18 positions in a dual-row configuration with 9 contacts per row, all on a 1.27 mm (0.050 inch) pitch. This fine pitch allows routing of 18 signals in a footprint considerably smaller than a standard 2.54 mm pitch connector, making it ideal for size-constrained designs.
How does the low-profile suffix L in SFM-109-02-L-D-A-K-TR affect PCB assembly clearance?
The L suffix designates a low-profile mating height, reducing the overall stack height between the two mating PCBs to approximately 3 mm to 4 mm depending on the selected mating header stack height. This low profile is critical in stacked PCB assemblies inside compact enclosures where total system height is constrained to under 10 mm.
Which high-reliability applications drive the selection of SFM-109-02-L-D-A-K-TR over standard socket strips?
The SFM-109-02-L-D-A-K-TR's high-reliability contacts rated for over 200 mating cycles make it preferred in test and measurement fixtures, medical devices, and portable field equipment where boards are frequently removed for maintenance or calibration. Standard socket strips without the high-reliability contact rating degrade after far fewer insertions at 1.27 mm pitch.
Can the SFM-109-02-L-D-A-K-TR be sourced without tape-and-reel packaging for prototype builds?
Yes, the SFM-109-02-L-D-A-K variant without the TR suffix is available in strip packaging for prototype quantities. Both variants share the identical 18-position dual-row 1.27 mm pitch SMT footprint, so engineers can prototype with strip-packaged parts and transition to the tape-and-reel SFM-109-02-L-D-A-K-TR for production without any PCB layout changes.
