Frequently Asked Questions
How many positions and what pitch does the SFM-139-02-ZZ-D-A-K-TR support?
The SFM-139-02-ZZ-D-A-K-TR offers 78 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, providing one of the highest pin densities available in SAMTEC's SFM series for space-constrained board-to-board interconnects.
For which server or telecom applications is the SFM-139-02-ZZ-D-A-K-TR recommended?
This connector suits server backplane assemblies, line cards, and telecom switching platforms requiring 78-pin SMT mezzanine interconnects at 1.27 mm pitch, where high contact reliability and compact board footprint over hundreds of insertion cycles are critical.
How does the SFM-139-02-ZZ-D-A-K-TR differ from lower-density SAMTEC SFM variants?
The SFM-139 variant provides 78 positions versus the 66-position SFM-133, offering 12 additional signal or power pins at the same 0.050" (1.27 mm) pitch in an equivalent SMT dual-row footprint, useful when I/O count grows but board area stays fixed.
