Key Features
- 88 positions in a dual-row 0.050" (1.27 mm) pitch SMT configuration delivers high-density interconnection in half the board space of 0.100" pitch alternatives
- High-reliability socket design with gold-plated contacts ensures low contact resistance and extended mating cycle life exceeding 100 insertions for field-serviceable modules
- Surface mount termination enables automated reflow assembly, reducing hand-soldering labor and improving solder joint consistency in production builds
Applications
SFM-144-T2-FM-D-A-K is used in high-density mezzanine and daughter-card interconnects for communications equipment, defense electronics, and test instrumentation where 0.050" pitch conserves board area. The socket strip format allows daughter boards to be removed and replaced without desoldering, supporting modular system architectures. Its high-reliability rating suits aerospace and industrial embedded computing applications with stringent vibration and thermal cycling requirements.

Frequently Asked Questions
What pitch and position count does SFM-144-T2-FM-D-A-K offer, and how does this compare to standard 0.100" strips?
SFM-144-T2-FM-D-A-K provides 88 positions at 0.050" (1.27 mm) pitch in a dual-row layout, achieving the same pin count as a 0.100" strip in roughly half the board length. This 44-per-row configuration suits high-density mezzanine cards where connector footprint is constrained to under 60 mm board width.
For which system architectures is the SFM-144-T2-FM-D-A-K socket strip most appropriate?
The SFM-144-T2-FM-D-A-K is well suited for modular embedded computing platforms, FPGA mezzanine cards (FMC), and plug-in daughter boards in telecommunications and defense systems. The 88-position, 0.050" pitch socket accommodates 44 differential pairs or 88 single-ended signals, enabling high-speed data busses within a compact 1.27 mm pitch footprint.
How many mating cycles can the SFM-144-T2-FM-D-A-K socket withstand in field-serviceable designs?
Samtec SFM-series high-reliability socket strips are rated for a minimum of 100 mating cycles with gold-plated contacts, making SFM-144-T2-FM-D-A-K suitable for field-replaceable daughter cards in instrumentation and communications equipment. The 0.050" pitch dual-row design maintains consistent 50-ohm impedance alignment across all 88 positions during repeated insertion.
