What are the key features of SFM-123-02-S-D-A-P-TR?
- 46-position dual-row socket on 0.050 inch (1.27 mm) pitch enabling high-density signal interconnect in compact PCB layouts
- High-reliability socket strip construction with gold-plated contacts supporting low insertion-force mating cycles for frequent board swaps
- Surface-mount termination compatible with standard reflow soldering up to 260°C for automated SMT assembly lines
- Tape-and-reel (TR) packaging enabling continuous pick-and-place feeder operation for high-volume production runs
What is SFM-123-02-S-D-A-P-TR used for?
The SFM-123-02-S-D-A-P-TR is used in high-density mezzanine and daughter-card assemblies where 46 signal contacts must be routed between stacked PCBs on a fine 0.050 inch pitch, reducing interconnect footprint compared to standard 0.100 inch alternatives. It is well suited for FPGA expansion boards, test fixture sockets, and embedded computing modules where repeated board insertion cycles demand a reliable, low-distortion contact interface. Communication and data acquisition hardware that requires fine-pitch SMT receptacles also benefits from this connector's compact dual-row layout.

Frequently Asked Questions
How does the 0.050 inch pitch of the SFM-123-02-S-D-A-P-TR compare to standard 0.100 inch connectors for high-density designs?
At 0.050 inch (1.27 mm) pitch, the SFM-123-02-S-D-A-P-TR carries 46 contacts in roughly the same linear footprint as a 23-position 0.100 inch connector, halving the board space required for the same signal count. This density advantage is critical in FPGA daughter cards, small form-factor compute modules, and portable instrument boards where PCB area is strictly limited.
For a test fixture designed to insert and remove boards hundreds of times, does the SFM-123-02-S-D-A-P-TR provide sufficient mating durability?
SAMTEC SFM-series high-reliability socket strips are rated for multiple insertion cycles using precision machined contacts, and their gold-plated terminations maintain low contact resistance—typically below 20 mΩ—even after repeated mating. This makes the SFM-123-02-S-D-A-P-TR a practical choice for automated test equipment fixtures where modules are swapped frequently during production or validation testing.
What reflow soldering conditions apply to the SFM-123-02-S-D-A-P-TR surface-mount termination?
The surface-mount termination on the SFM-123-02-S-D-A-P-TR follows JEDEC J-STD-020 moisture sensitivity requirements and is compatible with lead-free reflow profiles peaking at approximately 260°C. Its tape-and-reel format feeds directly into pick-and-place machines, and the SMT pads align to IPC-7351 land pattern standards, simplifying PCB library setup.
When should a designer prefer a 46-position dual-row SFM connector over two separate 23-position single-row connectors?
A single 46-position dual-row connector like the SFM-123-02-S-D-A-P-TR reduces the component count from two parts to one, lowers assembly placement time, and provides a mechanically coupled mating interface that resists differential rocking stress. For mezzanine boards that carry mixed signal and power contacts across 46 pins, the dual-row format also shortens the overall connector length by approximately 50% compared to a single-row arrangement of equivalent position count.
