Key Features
- 8-position dual-row 0.050" (1.27 mm) pitch socket strip enables high-density signal interconnection in compact SMT PCB layouts
- High-reliability construction engineered for demanding environments including repeated mating cycles and vibration resistance in industrial applications
- Surface mount package with tape-and-reel (TR) format supports fully automated pick-and-place assembly at production volumes
- K option provides additional mechanical retention or keying to prevent mis-mating in dual-row configurations
Applications
The SFM-104-02-H-D-A-K-TR is ideal for high-density board-to-board and mezzanine interconnections in compact embedded systems, FPGAs, and DSP daughtercards where 0.050" pitch reduces PCB footprint compared to standard .100" connectors. Its high-reliability socket strip construction suits aerospace, defense, and industrial automation applications that demand durability through thousands of mating cycles and exposure to vibration. The tape-and-reel packaging enables seamless integration into automated SMT assembly lines for volume production.

Frequently Asked Questions
What pitch and position count does SFM-104-02-H-D-A-K-TR provide for high-density PCB designs?
The SFM-104-02-H-D-A-K-TR features a 0.050" (1.27 mm) pitch with 8 positions arranged in a dual-row configuration, providing 4 pins per row. This fine pitch allows designers to route twice the signal density of standard .100" connectors in the same PCB footprint, which is critical for compact embedded computing and mezzanine card applications.
How does the high-reliability designation of SFM-104-02-H-D-A-K-TR differ from standard socket strips?
Samtec's high-reliability SFM series uses precision-machined contacts with tighter dimensional tolerances and higher spring force to maintain contact resistance below 20 milliohms over more than 500 mating cycles. Standard socket strips are typically rated for 30 to 50 mating cycles, making the SFM series the preferred choice for test fixtures, modular industrial controllers, and aerospace avionics that require repeated connector engagement.
Which surface mount assembly processes are compatible with SFM-104-02-H-D-A-K-TR?
The SFM-104-02-H-D-A-K-TR is a surface mount connector packaged in tape-and-reel (TR) format compatible with standard pick-and-place equipment. It supports lead-free reflow soldering at peak temperatures up to approximately 260°C per IPC J-STD-001, and its 0.050" pitch footprint can be defined with standard SMT land pattern guidelines for 1.27 mm pitch connectors.
What does the K option in SFM-104-02-H-D-A-K-TR indicate about mating compatibility?
The K suffix in Samtec's SFM series denotes a keying or retention feature that prevents incorrect mating orientation between the socket and its mating plug, reducing the risk of misalignment damage in dual-row 0.050" pitch assemblies. This is particularly valuable in field-serviceable equipment such as industrial controllers and medical device modules where maintenance personnel may replace daughtercards under time pressure.
