Frequently Asked Questions
How many signal positions does the SFM-146-02-ZZ-D-A-K-TR support, and what is its row configuration?
The SFM-146-02-ZZ-D-A-K-TR provides 92 positions arranged in a dual-row configuration at 0.050-inch (1.27 mm) pitch, delivering high pin density for board-to-board mezzanine interconnects in a compact SMT footprint suitable for space-constrained PCB designs.
Which header series does this SAMTEC socket mate with for a complete board-to-board stack?
This SFM series socket is designed to mate with corresponding SAMTEC TSM or TFC dual-row header strips at 0.050-inch pitch, enabling reliable 92-position board-to-board connections with typical contact resistance below 20 milliohms and mating retention forces suitable for industrial vibration environments.
What assembly process does the surface-mount termination style support for high-volume production?
The surface-mount termination enables standard paste-print and reflow soldering, with the -TR tape-and-reel packaging allowing automated pick-and-place placement at production line speeds. This eliminates manual through-hole insertion for 92 pins, reducing assembly cycle time and minimizing solder joint defect rates in volume manufacturing of boards with dual-row 0.050-inch pitch connectors.
For a daughter-card interface with 90+ signal lines, when is SFM-146-02-ZZ-D-A-K-TR preferred over a 0.100-inch pitch alternative?
When PCB real estate is limited and a 92-contact interface must fit within roughly 2.3 inches of edge space, the 0.050-inch pitch SFM series occupies approximately half the board length of an equivalent 0.100-inch pitch connector. Embedded computing modules and compact industrial I/O boards regularly use this trade-off to route 92 signals through a smaller footprint without sacrificing signal count.
