What are the key features of SFM-143-L2-ZZ-D-A-K-TR?
- 86-position dual-row layout on a 0.050" (1.27 mm) pitch provides 172 total contacts in a compact SMT socket strip for high-density board-to-board applications
- High-reliability socket strip construction with precision contact alignment ensures low insertion force and consistent signal integrity over the product lifecycle
- Tape-and-reel (TR) packaging supports high-speed automated pick-and-place SMT assembly for cost-effective high-volume production
What is SFM-143-L2-ZZ-D-A-K-TR used for?
The SFM-143-L2-ZZ-D-A-K-TR is designed for high-density mezzanine board interconnect in FPGA evaluation boards, high-performance computing modules, and advanced signal processing platforms requiring 86 dual-row connections within a 0.050 inch pitch SMT footprint. Its high-reliability construction and precision contact geometry also make it well suited for instrumentation daughter cards, RF test fixtures, and data acquisition modules where repeatable low-resistance mating is essential across many operational cycles.

Frequently Asked Questions
How many total contacts does the 86-position dual-row SFM-143-L2-ZZ-D-A-K-TR provide, and how does that compare to a 0.100 inch pitch equivalent?
The SFM-143-L2-ZZ-D-A-K-TR has 86 positions arranged in 2 rows for 172 total contacts at 0.050 inch pitch, which packs approximately 4 times the contact density of a standard 0.100 inch pitch dual-row connector of the same body length, enabling significantly higher signal counts per unit of PCB edge space.
For an FPGA mezzanine card requiring 160 or more I/O lines, how suitable is the SFM-143-L2-ZZ-D-A-K-TR compared to a larger 100-position part?
The SFM-143-L2-ZZ-D-A-K-TR provides 172 contacts across 86 dual-row positions at 0.050 inch pitch, which exceeds a 160 I/O requirement and leaves 12 contacts available for power or ground, making it a more efficient single-part solution than using two smaller 0.050 inch pitch connectors to reach 160 lines.
Which automated assembly requirement does the tape-and-reel format of the SFM-143-L2-ZZ-D-A-K-TR address for high-volume SMT production?
The -TR suffix designates tape-and-reel packaging compatible with standard EIA-481 carrier tape, allowing placement by automated pick-and-place machines at typical throughputs of 1000 to 5000 components per hour, eliminating manual tray-feed interruptions and ensuring consistent 0.050 inch pitch socket strip positioning during reflow soldering.
