Board-to-board footprint and routing density
The 1-2314917-4: The 0.083" (2.11 mm) post length defines the solder tail depth for through-hole assembly.
The UL94 V-0 LCP housing holds up in equipment requiring flame-rated materials inside an enclosure.
The solder tails are tin-plated (12.0 µinch) for good solderability with standard lead-free processes.
