Key Features
- 84-position dual-row layout with 1.27 mm (0.050") pitch enabling high-density SMT interconnects in compact PCB designs
- High-reliability gold-plated contacts rated at 1A per pin for consistent signal integrity across hundreds of mating cycles
- Low-profile surface mount configuration compatible with automated pick-and-place assembly and standard reflow soldering up to 260°C
Applications
The SFM-142-L2-LM-D-A-K is ideal for high-density board-to-board stacking in embedded systems, FPGA daughter cards, and mezzanine modules requiring 84 reliable signal connections at 1.27 mm pitch. It is also widely used in test and measurement fixtures and communication hardware where repeated mating cycles demand gold-plated contact durability.

Frequently Asked Questions
What pitch and position count does the SFM-142-L2-LM-D-A-K offer, and how does this affect PCB layout density?
The SFM-142-L2-LM-D-A-K uses a 1.27 mm (0.050 inch) pitch in a dual-row 84-position configuration, allowing designers to route 84 signals within a very compact PCB footprint compared to 2.54 mm pitch alternatives.
How many mating cycles and what current rating is the SFM-142-L2-LM-D-A-K designed for?
SAMTEC rates the SFM-142-L2-LM-D-A-K for at least 100 mating cycles with gold-plated contacts carrying up to 1A per pin, making it suitable for test fixtures, daughterboards, and systems requiring repeated connection and disconnection.
Which SAMTEC header series mates with the SFM-142-L2-LM-D-A-K?
The SFM-142-L2-LM-D-A-K mates with SAMTEC's TSM and SSM series 1.27 mm pitch dual-row headers. These 84-position mating headers are available in through-hole and SMT variants, giving engineers flexibility in board-to-board stacking heights from 5 mm to 20 mm.
For a space-constrained FPGA mezzanine board, why choose SFM-142-L2-LM-D-A-K over a 2.54 mm pitch socket?
At 1.27 mm pitch, the SFM-142-L2-LM-D-A-K delivers 84 signal connections in roughly half the board area required by a 2.54 mm pitch 84-position socket. This makes it the preferred choice when PCB real estate is limited and signal density requirements exceed what standard 0.1 inch connectors can provide.
