Pin geometry and stack-up planning
The 87900-442HLF: Three lengths define the mechanical fit: the post tail is 0.120" (3.05 mm) — confirm your board thickness and plated-through-hole depth can absorb this without barrel collapse on wave-solder reflow. The mating pin engagement length is 0.720" (18.29 mm), and the overall contact length is 0.940" (23.88 mm). The 0.100" insulation height sets the board separation; the push-pull fastening type means the header locks positively when fully seated — no screw or secondary clip needed, which speeds automated assembly.
Compliance and material rating
The UL94 V-0 flammability rating on the housing means the connector meets the self-extinguish requirement for enclosed equipment — relevant for industrial automation enclosures and any product required to clear UL 94 at V-0 class. No RoHS, REACH, or UL recognition number is listed on this spec sheet; confirm current compliance documentation directly with Amphenol FCI if your procurement spec requires a certificate on file.
