- Gold-plated contacts with 1 A per pin rating supporting both signal and moderate power distribution across all 88 positions
- High-reliability construction meeting industrial and defense interconnect standards with -55°C to +125°C thermal performance
- Surface-mount SMT footprint compatible with standard reflow soldering and automated pick-and-place PCB assembly
Applications
The SFM-144-02-F-D-A-K is used in high pin-count mezzanine board-to-board interconnects for FPGA carrier boards, embedded computing modules, and multi-channel data acquisition systems requiring 88 or more simultaneous connections at 1.27 mm pitch. It supports simultaneous routing of wide parallel data buses, differential signal pairs, multiple power rails, and control signals between stacked PCBs in a compact footprint. This socket strip is also specified in defense avionics and industrial automation equipment where high-cycle-life reliability and -55°C to +125°C thermal operation are mandatory.

Frequently Asked Questions
What differentiates the SFM-144-02-F-D-A-K from other 88-position socket strips in terms of pitch and contact rating?
The SFM-144-02-F-D-A-K uses a 0.050" (1.27 mm) pitch with gold-plated contacts rated at 1 A per pin, delivering 88 A total current capacity in a dual-row SMT footprint that spans roughly 57 mm. Compared to 2.54 mm pitch alternatives with similar pin counts, this connector occupies less than half the board length while maintaining equivalent per-pin current handling.
Which industrial or defense reliability standards does the SFM-144-02-F-D-A-K support for harsh environment deployments?
The connector is rated for -55°C to +125°C operation with gold plating maintaining low contact resistance across this 180°C thermal span. These parameters align with IPC-9592 connector reliability requirements and MIL-DTL-55302 class performance levels, making the SFM-144-02-F-D-A-K suitable for avionics, shipboard electronics, and industrial control systems exposed to wide temperature swings and vibration.
For a 64-bit parallel bus interface design, how well does the SFM-144-02-F-D-A-K accommodate data, power, and control signals?
With 88 positions in a dual-row layout, a 64-bit data bus consumes 64 pins, leaving 24 pins for address lines, chip select, clock, power, and ground. Distributing power across multiple pins at 1 A per pin allows supplying 5 A to 10 A of regulated 3.3 V or 5 V power directly through the same mezzanine connector, eliminating separate power headers in space-constrained stacked board designs.
How does the reflow-soldered SMT footprint of the SFM-144-02-F-D-A-K compare to press-fit alternatives for production reliability?
Reflow soldering the SFM-144-02-F-D-A-K at standard lead-free peak temperatures around 260°C creates a metallurgically bonded joint at each of the 88 pads, providing lower contact resistance and higher vibration resistance than press-fit connections at 1.27 mm pitch. This makes it preferable for high-vibration environments such as industrial machinery and automotive test fixtures where press-fit retention forces on fine-pitch pins can degrade over thousands of mechanical cycles.
