What are the key features of SFM-129-T2-ZZ-D-A-K-TR?
- 58-position dual-row surface-mount socket at 0.050" (1.27 mm) pitch delivers ultra-high signal density for compact FPGA mezzanine and SOM board-to-board stacking
- High-reliability SFM socket contact system provides consistent mating force and contact retention across thousands of insertion cycles for demanding industrial applications
- Tape-and-reel (-TR) and keyed (-K) options enable error-proof automated pick-and-place assembly, preventing incorrect orientation in high-volume production runs
What is SFM-129-T2-ZZ-D-A-K-TR used for?
The SFM-129-T2-ZZ-D-A-K-TR is ideal for FPGA mezzanine cards, system-on-module (SOM) carrier boards, and high-speed backplane interconnects requiring 58 dual-row positions at 0.050" pitch on a surface-mount footprint. The keying feature prevents incorrect mating in multi-connector assemblies, reducing field failures in communications, embedded computing, and test and measurement equipment. Tape-and-reel packaging streamlines high-volume SMT production by enabling seamless integration with automated assembly systems.

Frequently Asked Questions
How many positions does the SFM-129-T2-ZZ-D-A-K-TR provide, and at what pitch?
The SFM-129-T2-ZZ-D-A-K-TR provides 58 total positions arranged in a dual-row surface-mount socket at 0.050" (1.27 mm) pitch, with 29 contacts per row, making it one of the higher-density SFM-series options for compact board-to-board stacking applications.
What does the -K (keyed) suffix mean on SFM-129-T2-ZZ-D-A-K-TR, and why is it important?
The -K suffix indicates a polarization key that physically prevents the connector from being mated in the wrong orientation. In assemblies with multiple adjacent 58-position socket strips, the keying feature eliminates mismatched connections that could damage a 3.3 V or 1.8 V signal rail, reducing rework costs and field failure rates.
How does the SFM-129-T2-ZZ-D-A-K-TR compare to a lower-position SFM connector for a high-channel-count signal application?
Compared to a 28-position SFM variant, the 58-position SFM-129-T2-ZZ-D-A-K-TR carries more than double the signal count in a footprint that is roughly proportionally longer, reducing the number of connectors needed on a given board from 2 down to 1. This simplifies PCB routing and lowers total BOM cost per signal channel at high production volumes.
