Frequently Asked Questions
How many contacts does the SFM-142-L2-LM-D-A-P provide, and what pitch does it use?
The SFM-142-L2-LM-D-A-P offers 84 contacts arranged in a dual-row configuration at 0.050" (1.27 mm) pitch. This ultra-fine pitch enables very high contact density on small PCB footprints, making it a strong choice for high-speed signal routing in aerospace, defense, and advanced telecommunications daughtercard assemblies.
Which SAMTEC headers mate with the SFM-142-L2-LM-D-A-P, and what stack heights are available?
The SFM-142-L2-LM-D-A-P mates with SAMTEC SFH and SFM series headers that share the same 0.050" pitch and 84-position dual-row layout. Available mated stack heights typically range from 8 mm to 20 mm depending on the selected header variant, giving designers flexibility to accommodate components between stacked boards.
What compliance certifications apply to the SFM-142-L2-LM-D-A-P for aerospace and defense procurement?
The SFM-142-L2-LM-D-A-P is RoHS compliant and lead-free per EU Directive 2011/65/EU. SAMTEC provides full traceability documentation for their high-reliability SFM series connectors, and the gold-plated contacts meet contact resistance specifications that satisfy demanding aerospace and defense qualification programs requiring 0.050" pitch socket strips.
How does the 0.050" pitch of the SFM-142-L2-LM-D-A-P compare to standard 0.100" pitch connectors for space-critical designs?
The 0.050" pitch halves the contact spacing compared to standard 0.100" pitch connectors, allowing the 84-position SFM-142-L2-LM-D-A-P to occupy a footprint comparable to a 42-position 0.100" connector. This density advantage is critical in space-constrained high-speed designs where routing 84 signals through a conventional pitch would require much more PCB area.
