Applications
The SFM-146-T2-STL-D-A-P is designed for high-density interconnect applications in computing, networking, and test equipment where space constraints demand 0.050 inch pitch connectors. Its 92-position dual-row configuration makes it suitable for daughter card attachment, FPGA mezzanine modules, and high-speed signal breakout in rack-mounted instrumentation. The anti-wicking feature ensures process reliability in automated SMT environments with lead-free solder paste.

Frequently Asked Questions
How does the 0.050 inch pitch of SFM-146-T2-STL-D-A-P compare to standard 0.100 inch pitch connectors for board space savings?
At 0.050 inch (1.27 mm) pitch, this 92-position dual-row socket strip occupies roughly half the PCB footprint of equivalent 0.100 inch pitch connectors. This makes it valuable in high-density PCB layouts where preserving space for additional components or routing layers is critical.
What does the anti-wicking contact design in SFM-146-T2-STL-D-A-P prevent during SMT assembly?
The anti-wicking contact design prevents solder from flowing up the contact barrel during reflow soldering at peak temperatures around 260°C. This maintains electrical integrity across all 92 positions, avoiding intermittent open circuits that can occur when solder wicks into the contact mating zone.
In which high-reliability application environments is SFM-146-T2-STL-D-A-P most commonly deployed?
This 92-position surface mount socket strip is commonly used in mil-aero avionics, medical imaging equipment, and industrial control systems where vibration resistance and long contact life over 500 mating cycles are required. The precision machined contacts handle both digital and analog signals up to 1 A per contact.
What lifecycle risk should procurement teams consider when designing with SFM-146-T2-STL-D-A-P?
SAMTEC SFM series connectors are generally active production items, but 92-position configurations in non-standard pitch variants may carry longer lead times of 8 to 12 weeks from distribution. Procurement teams should establish safety stock of at least 200 pieces for production programs exceeding 1,000 units per quarter.
