18-Position BERGSTIK II Unshrouded Header
The Amphenol BERGSTIK II 87916-418HLF is an 18-position, single-row, unshrouded pin header on the standard 0.100" (2.54mm) pitch. The overall contact length is 1.058" (26.87mm), with a mating length of 0.830" (21.08mm) and a post length of 0.128" (3.25mm). This is a fully loaded header — all 18 positions are populated.
The 87916-418HLF is the 18-position variant in the BERGSTIK II family of unshrouded headers. The key selection parameters are the position count and the contact finish. Tin-plated versions like this one are the cost-optimized choice for single-mate or infrequent-disconnect applications — the tin finish wipes clean on insertion but wears faster under repeated cycling than a gold-plated sibling would. If your BOM calls for an 18-position unshrouded header at 0.100" pitch, this is the direct fit; the 100.0 µ" tin thickness is well above the typical 40-60 µ" flash, so it handles a reasonable number of mating cycles in a controlled environment.
