Frequently Asked Questions
What distinguishes the SFM-123-02-F-D-A-K from the SFM-123-02-L-D-A-K variant?
The SFM-123-02-F-D-A-K and SFM-123-02-L-D-A-K share the same 46-position dual-row 0.050" (1.27 mm) pitch configuration, but differ in their tail length or termination style suffix. The F suffix typically indicates a shorter or flush tail variant, affecting solder joint height on the PCB. Both are SMT components suitable for high-density 1.27 mm pitch interconnect designs.
How many signals can the SFM-123-02-F-D-A-K route in a dual-row configuration?
With 46 total positions arranged in 2 rows of 23 contacts each at 0.050" (1.27 mm) pitch, the SFM-123-02-F-D-A-K can route up to 46 independent signals or a mix of signal and power lines. This density is well suited for FPGA I/O expansion or processor module interfaces requiring many parallel data lines in a compact SMT socket.
Which soldering method is compatible with the SFM-123-02-F-D-A-K for production assembly?
The SFM-123-02-F-D-A-K uses surface mount termination, making it fully compatible with standard reflow soldering processes. Pick-and-place automation handles its placement on 1.27 mm pitch SMT pads, enabling high-throughput production. This eliminates the need for wave soldering or hand assembly, reducing defect rates on high-volume PCB manufacturing lines.
In what high-reliability environments is the SFM-123-02-F-D-A-K typically deployed?
The SFM-123-02-F-D-A-K is rated for high-reliability use cases including industrial control systems, telecommunications rack equipment, and defense electronics where connector performance must remain stable across temperature cycling and mechanical vibration. Its 1.27 mm pitch dual-row design supports 46-pin high-speed signal interconnects in space-constrained chassis and module stacking configurations.
