What are the key features of SFM-146-02-H-D-LC?

  • 92-position dual-row SMT socket strip at 0.050" pitch delivering ultra-high signal density for mezzanine and module interconnect designs
  • High-profile (H) contacts with low-clearance (LC) housing allow controlled stack height while maintaining secure 92-pin engagement
  • High-reliability SMT construction with gold-plated contacts ensuring consistent signal integrity across 500+ mating cycles

What is SFM-146-02-H-D-LC used for?

The SFM-146-02-H-D-LC is engineered for dense board-to-board and mezzanine stacking applications in networking equipment, advanced instrumentation, and FPGA-based compute platforms requiring 92 signals in a compact 0.050" pitch format. The low-clearance (LC) housing variant minimizes stack height between mated PCBs, making it suitable for slim chassis and embedded system enclosures with tight vertical clearance. Its surface-mount footprint supports fully automated SMT assembly without the additional drilling required by through-hole alternatives.

Frequently Asked Questions

What specific advantage does the low-clearance (LC) variant of the SFM-146-02-H-D-LC provide in stacked-board designs?

The low-clearance (LC) designation on the SFM-146-02-H-D-LC indicates a reduced housing height that minimizes the air gap between mated PCBs in a stacked assembly. For compact enclosures or chassis with vertical space constraints under 5 mm between boards, the LC variant allows designers to maintain 92-position, 0.050" pitch connectivity while keeping the overall board stack height within mechanical tolerances that standard-height sockets would exceed.

How does the 92-position count at 0.050" pitch of the SFM-146-02-H-D-LC benefit FPGA development board interconnects?

FPGAs with 92 or more user I/O pins benefit directly from the SFM-146-02-H-D-LC because it provides a single dual-row socket that maps all 92 signals in a footprint roughly half the length of a comparable 0.100" pitch connector. This allows FPGA daughter cards to expose a full 92-bit parallel interface through a single SFM-series connector pair, simplifying board layout and reducing the number of connectors needed compared to using multiple smaller-pitch or lower-density headers.

How many mating cycles is the SFM-146-02-H-D-LC rated for, and what applications require that level of durability?

The SFM-146-02-H-D-LC is built to SAMTEC's high-reliability socket strip standard, which specifies a minimum of 500 mating cycles with gold-plated contacts maintaining contact resistance below 20 mΩ throughout. This durability level is relevant for test and measurement fixtures that repeatedly connect and disconnect 92-position module cards during production testing, as well as for field-replaceable module systems in industrial controllers where boards must be swapped without connector replacement.
