What are the key features of SFM-140-L2-S-D-LC-TR?
- 80-position dual-row Tiger Eye socket strip at 1.27 mm (0.050 inch) pitch with low-clearance (LC) SMT design minimizing board stack height in mezzanine assemblies
- 30 micro-inch gold contact finish on female square pin sockets with tin-nickel barrier termination for reliable long-term solderability and corrosion resistance
- Tape-and-reel (TR) packaging for automated SMT pick-and-place, with 9.4-year product life rating and Tiger Eye dual-beam wiping contact technology
What is SFM-140-L2-S-D-LC-TR used for?
The SFM-140-L2-S-D-LC-TR is optimized for low-profile mezzanine card sockets in military embedded computing, aerospace payload modules, and high-density telecom blades that require 80 pins at 1.27 mm pitch with minimal inter-board clearance. Its Tiger Eye female contacts accommodate slight PCB coplanarity variations while maintaining contact resistance below 20 milliohms across -55 °C to +125 °C operating temperatures. Tape-and-reel delivery supports high-volume automated assembly lines reducing manual placement errors for high pin-count SMT socket strips.

Frequently Asked Questions
What does the LC designation mean for the SFM-140-L2-S-D-LC-TR and how does it affect board stack height?
The LC (low-clearance) designation on the SFM-140-L2-S-D-LC-TR indicates a reduced-height mating profile that minimizes the inter-board gap in stacked PCB assemblies. The low-clearance design allows a board separation of approximately 4 mm or less, making this 80-position 1.27 mm pitch socket strip ideal for compact mezzanine card stacks in aerospace and military computing chassis with tight height constraints.
What contact finish specification does the SFM-140-L2-S-D-LC-TR use for the mating interface?
The SFM-140-L2-S-D-LC-TR uses 30 micro-inch (30 µin) gold plating on the mating contact surfaces, which provides low contact resistance and high durability across multiple insertion cycles. The termination side uses tin (Sn) with a nickel (Ni) barrier to prevent tin whisker growth during lead-free reflow soldering at temperatures up to 260 °C.
For which mezzanine and board stacking standards is the SFM-140-L2-S-D-LC-TR most appropriate?
The SFM-140-L2-S-D-LC-TR is most appropriate for FMC (VITA 57.1), XMC (VITA 42), and AMC mezzanine standards requiring 80-pin dual-row 1.27 mm pitch sockets. Its Tiger Eye contacts rated at 1 A per pin support signal, low-power, and auxiliary power lines in FPGA mezzanine card applications operating from -55 °C to +125 °C in rugged embedded computing systems.
What is the factory lead time for the SFM-140-L2-S-D-LC-TR and what tape-and-reel quantities are typical?
The standard factory lead time for the SFM-140-L2-S-D-LC-TR is approximately 6 weeks and 4 days from Samtec when ordering production quantities. The tape-and-reel (TR) packaging format supports automated pick-and-place assembly in volumes of hundreds to thousands of units, with the 80-position 1.27 mm pitch socket strip packed at standard EIA-481 reel quantities for high-volume SMT production runs.
