What are the key features of SFM-149-02-SM-D-A-K?
- 98 positions in dual-row layout at 0.050" (1.27mm) pitch enabling ultra-high-density board interconnects in compact designs
- Gold-plated contacts with anti-wicking treatment ensure consistent signal integrity and long-term reliability in demanding environments
- Surface mount termination with A-K kinked lead option simplifies soldering and provides enhanced solder joint robustness
What is SFM-149-02-SM-D-A-K used for?
The SFM-149-02-SM-D-A-K is ideal for dense signal routing between PCBs in high-performance computing, FPGA development boards, and telecommunications line cards where 0.050" pitch maximizes connector density. Its high-reliability socket strip construction suits aerospace, defense instrumentation, and medical devices requiring stable mating cycles and consistent low-contact-resistance performance.

Frequently Asked Questions
How does the 0.050" pitch of SFM-149-02-SM-D-A-K compare to standard 0.100" connectors for high-density designs?
The SFM-149-02-SM-D-A-K uses a 0.050" (1.27 mm) pitch, which is half the spacing of standard 0.100" connectors, allowing engineers to fit 98 positions in roughly the same PCB footprint that a 0.100" connector would use for 49 positions. This makes it ideal for bandwidth-intensive and space-constrained designs in compute or telecom hardware.
What does the 'A-K' suffix indicate on the SFM-149-02-SM-D-A-K, and why does it matter for PCB assembly?
The 'A-K' suffix designates the kinked lead variant of the SFM series surface mount socket strip. The kinked leads provide a mechanical standoff that holds the connector level on the PCB pad during reflow soldering at up to 260°C, reducing tombstoning risk and improving solder joint quality, especially on dense 0.050" pitch layouts.
Can SFM-149-02-SM-D-A-K be used as a replacement or alternative to similar 98-position connectors from other vendors?
Yes, the SFM-149-02-SM-D-A-K can serve as a direct or near-direct replacement for other 0.050" dual-row 98-position SMT socket strips, including compatible Millmax and Harwin products, provided the PCB footprint matches the 1.27 mm pitch standard. Engineers should verify mating plug height and contact current rating, which is typically rated at 1A per contact for SFM series connectors.
