- High-reliability SMT construction with 2 mm stack height suited for space-constrained PCB layouts
Applications
The SFM-149-T2-F-D-A is ideal for high-density board-to-board interconnect applications in telecommunications, test and measurement, and industrial automation systems. Its compact 0.050" pitch and dual-row design make it suitable for mezzanine board stacking and modular daughtercard configurations where space is limited. Engineers also use it in high-reliability data acquisition hardware and RF instrumentation requiring stable 98-position electrical interfaces.

Frequently Asked Questions
What is the contact pitch and row count of the SFM-149-T2-F-D-A?
The SFM-149-T2-F-D-A features a 0.050" (1.27 mm) pitch with a dual-row arrangement, giving a total of 98 positions for high-density surface mount connectivity on compact PCB designs.
Which board-to-board stacking configurations support the SFM-149-T2-F-D-A socket strip?
This socket strip supports mezzanine and daughtercard stacking with a 2 mm stack height, making it compatible with SAMTEC's SFM and SFH header series in industrial, telecommunications, and test-and-measurement applications requiring 98 contacts.
How does the gold-plated contact finish on the SFM-149-T2-F-D-A improve long-term reliability?
The gold-plated finish resists oxidation and corrosion, maintaining low contact resistance over thousands of mating cycles. This is critical for high-reliability systems such as avionics modules and automated test equipment operating across a wide temperature range of -55°C to +125°C.
When is SFM-149-T2-F-D-A preferred over single-row socket strips?
The dual-row 98-position layout achieves nearly twice the signal density in the same board footprint length compared to a single-row 0.050" strip, reducing interconnect length by up to 40% and lowering PCB area cost in high-pin-count designs.
