Key Features
- 84-position dual-row socket at 0.050" (1.27 mm) pitch enabling twice the contact density of standard 0.100" connectors in the same PCB footprint
- High-reliability construction with gold-plated contacts for low contact resistance and extended mating cycle life in demanding SMT applications
- Surface mount form factor with recessed socket design protects mating pins from mechanical damage during handling and assembly
Applications
SFM-142-02-F-D-A-K is designed for high-density daughter card sockets, mezzanine board interconnects, and module-on-board applications in aerospace, defense, and industrial computing systems. Its 0.050" pitch dual-row layout supports 84-signal routing in a compact footprint, making it ideal for FPGAs, SoMs, and high-speed digital boards where space and signal density are critical.

Frequently Asked Questions
What pitch and position count does the SFM-142-02-F-D-A-K support?
The SFM-142-02-F-D-A-K has 84 positions in a dual-row configuration at 0.050" (1.27 mm) pitch, providing twice the contact density compared to standard 0.100" pitch connectors and enabling high signal count connections in space-constrained SMT designs.
In which high-reliability applications is SFM-142-02-F-D-A-K preferred over standard socket strips?
Its high-reliability construction with gold-plated contacts suits aerospace avionics, defense electronics, and industrial server blades where mating cycles can exceed 100 insertions and contact resistance must remain stable below 50 mΩ over the full operating temperature range of -55°C to +125°C.
How does the 0.050" pitch of SFM-142-02-F-D-A-K compare to SFM connectors at 0.100" pitch for module designs?
At 0.050" (1.27 mm) pitch, SFM-142-02-F-D-A-K accommodates 84 contacts in approximately the same board area as a 42-position 0.100" socket strip, allowing module designers to double their signal count without increasing PCB real estate, which is essential for high-density SoM and FPGA carrier board designs.
