The Amphenol FCI BERGSTIK II 87901-466HLF is a 66-position dual-row unshrouded header on a 0.100" (2.54mm) pitch, designed for board-to-board interconnect applications where a straight through-hole solder termination is required. This is the highest position count variant in the BERGSTIK II series at this pitch, giving you a dense signal interface across a single connector body.
Key features and fit considerations
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing are industry-standard for prototyping and production boards — the footprint matches the legacy 0.100" grid, so layout tools and autorouters handle it without special rules. The overall contact length of 1.040" (26.42mm) breaks down into a 0.820" (20.83mm) mating length and a 0.120" (3.05mm) post length for the solder tail — the short post suits standard 0.062" (1.6mm) PCBs without excessive protrusion.
