Key Features
- High-reliability socket strip design with 10 positions at 0.050" (1.27 mm) pitch for precise board-to-board mating in space-constrained SMT assemblies
- Gold-plated mating contacts on phosphor bronze base ensure low contact resistance below 20 mΩ and corrosion resistance across industrial temperature ranges
- Surface mount termination with dual-row layout enables compact PCB footprint and compatibility with SAMTEC TFC and TFM series header strips
Applications
The SFM-105-02-FM-D-A socket strip is used in high-reliability mezzanine and daughter-card interconnect applications in military electronics, industrial control modules, and medical instrumentation. Its 10-position dual-row 0.050" pitch design mates with SAMTEC TFM and TFC series header strips, enabling modular PCB stack-up architectures with stack heights selectable from 6 mm to 20 mm. The surface mount configuration supports reflow soldering at up to 260°C peak, making it compatible with lead-free manufacturing processes.

Frequently Asked Questions
How many positions does the SFM-105-02-FM-D-A socket strip have, and which SAMTEC headers does it mate with?
The SFM-105-02-FM-D-A provides 10 positions in a dual-row, 5-per-row configuration at 0.050" (1.27 mm) pitch, mating with SAMTEC TFM and TFC series header strips. The stack height varies from 6 mm to 20 mm depending on the matched header pin length, suitable for mezzanine PCB designs with tight vertical clearance requirements.
For a high-vibration industrial environment, why is the SFM-105-02-FM-D-A a reliable 10-pin interconnect choice?
The SFM-105-02-FM-D-A uses high-reliability socket contacts rated for a minimum of 30 mating cycles with a contact normal force sufficient to maintain stable resistance below 20 mΩ in vibration environments per MIL-STD-202 Method 204. Gold plating (30 µin minimum) prevents oxidation across operating temperatures from -55°C to +125°C, common in industrial motor drives and rugged compute modules.
Can the SFM-105-02-FM-D-A withstand lead-free reflow soldering, and what is the peak soldering temperature?
Yes, the SFM-105-02-FM-D-A is rated for lead-free reflow soldering with a peak temperature of 260°C for up to 10 seconds, compliant with JEDEC J-STD-020 MSL requirements. The LCP housing maintains dimensional stability at these temperatures, ensuring that the 0.050" pitch coplanarity tolerance stays within ±0.1 mm after reflow.
How does the SFM-105-02-FM-D-A compare in board area to a 10-pin 0.100" pitch socket when PCB real estate is limited?
The SFM-105-02-FM-D-A at 0.050" pitch occupies approximately 25% of the PCB footprint of an equivalent 0.100" pitch 10-pin dual-row socket, reducing the connector zone from roughly 0.5 in² to 0.12 in². This space saving of over 0.3 in² is significant in PCB designs where the connector area competes with high-density BGA or power supply components.
