The Amphenol 67998-418HLF is an 18-position, dual-row unshrouded header from the BERGSTIK® II series, designed for board-to-board stacking applications. It uses a 0.100" (2.54mm) pitch on both rows and contacts, with a 0.100" (2.54mm) row spacing, matching the standard 0.100" grid for prototyping and production layouts. The through-hole solder termination and push-pull fastening make it a straightforward pin header for wire-wrap or soldered interconnects where a low-profile, unshrouded footprint is acceptable.
Key Specs and What They Mean for Fit
The 18 positions are fully loaded across two rows. The 0.100" pitch matches the standard 0.100" grid for prototyping and production layouts.
Construction and Environment
Phosphor bronze contacts with tin plating on both the mating and post ends. The UL94 V-0 black insulation handles the flame-rating requirement for equipment inside an enclosure. The overall contact length of 0.525" (13.34mm) — with 0.318" (8.08mm) mating length and 0.107" (2.71mm) post length — gives enough reach for standard 0.062" PCBs with room for a wire-wrap tail or solder fillet.
