What are the key features of SFM-142-02-ZZ-D-A-K-TR?
- 84 positions in dual-row 1.27 mm (0.050 inch) pitch for ultra-high-density SMT signal interconnect
- High-reliability socket construction with gold-plated contacts ensures low contact resistance below 20 mΩ for critical signal paths
- Tape-and-reel packaging enables seamless integration into automated SMT pick-and-place assembly at high production volumes
What is SFM-142-02-ZZ-D-A-K-TR used for?
SFM-142-02-ZZ-D-A-K-TR is designed for high-density board-to-board mezzanine stacking in aerospace, defense, and industrial computing platforms where 84 signal lines must be routed through a minimal PCB footprint. Its 1.27 mm pitch allows connector placement in space-constrained modules such as single-board computers, FPGA daughterboards, and signal processing cards. The high-reliability socket design maintains reliable electrical continuity over thousands of mating cycles and across wide temperature excursions.

Frequently Asked Questions
How does the 1.27 mm pitch of SFM-142-02-ZZ-D-A-K-TR compare to standard 2.54 mm pitch connectors for high-density designs?
The SFM-142-02-ZZ-D-A-K-TR uses 1.27 mm (0.050 inch) pitch, exactly half the spacing of standard 2.54 mm pitch connectors, allowing the same 84 positions to occupy roughly half the PCB length. For a dual-row 84-position layout, the 1.27 mm pitch connector spans approximately 53.3 mm, versus over 100 mm for a 2.54 mm pitch equivalent, a critical saving in compact computing and instrument modules where every millimeter counts.
What mating connector family is compatible with SFM-142-02-ZZ-D-A-K-TR for board-to-board stacking?
SFM-142-02-ZZ-D-A-K-TR is designed to mate with SAMTEC TSM or TFM series 1.27 mm pitch dual-row header strips in the corresponding 84-position configuration. The matched socket-and-header pair supports board stacking heights from approximately 8 mm to 20 mm depending on the header standoff length selected, making the combination suitable for compact mezzanine card designs in 1U rackmount or embedded computing form factors.
Is the SFM-142-02-ZZ-D-A-K-TR suitable for repeated plug-unplug cycles in field-serviceable equipment?
Yes, the SFM-142-02-ZZ-D-A-K-TR is built to the high-reliability SAMTEC SFM standard, rated for a minimum of 30 mating cycles while maintaining contact resistance below 20 mΩ and reliable signal integrity across all 84 positions. For field-serviceable industrial equipment such as modular instrumentation and plug-in sensor boards, this cycle rating comfortably accommodates periodic maintenance and board swap events over equipment lifetimes exceeding 10 years.
What production advantages does the tape-and-reel TR packaging of SFM-142-02-ZZ-D-A-K-TR offer over tray packaging?
The TR (tape-and-reel) suffix on SFM-142-02-ZZ-D-A-K-TR means each connector is individually pocketed on a 330 mm diameter carrier reel compatible with standard SMT feeders, enabling uninterrupted automated placement at rates up to 5,000 components per hour. Tray packaging requires manual handler loading between trays, adding up to 30 seconds per tray change and introducing placement misalignment risk on fine-pitch 1.27 mm footprints during high-volume runs of 10,000 or more boards.
