Frequently Asked Questions
What signal density advantage does the SFM-149-L2-STL-D-A offer over 2.54 mm pitch alternatives?
By using a 1.27 mm (0.050 inch) pitch, the SFM-149-L2-STL-D-A fits 98 positions in roughly half the board length needed by a 2.54 mm pitch equivalent, freeing significant PCB real estate in high-density FPGA and communication designs.
How many mating cycles is the SFM-149-L2-STL-D-A rated for, and what current does each contact support?
The SFM-149-L2-STL-D-A is rated for at least 100 mating cycles with gold-plated contacts supporting up to 1A per pin. This makes it appropriate for both production board stacking and semi-permanent test fixture configurations.
Which SAMTEC mating headers are recommended for use with SFM-149-L2-STL-D-A?
The SFM-149-L2-STL-D-A mates with SAMTEC TSM and SSM series 1.27 mm pitch dual-row headers available in through-hole and SMT versions. These mating headers support stacking heights from approximately 5 mm to 20 mm depending on the selected tail length option.
Can the SFM-149-L2-STL-D-A withstand standard SMT reflow soldering, and what peak temperature is supported?
Yes, the SFM-149-L2-STL-D-A is designed for surface mount reflow assembly and can withstand a peak reflow temperature of 260°C, in line with JEDEC J-STD-020 requirements. Its housing material is rated for this thermal exposure without dimensional distortion.
