The Amphenol FCI 78938-136HLF is the 36-circuit member of the BERGSTIK II single-row header series — a board-to-board, right-angle through-hole connector rated 5 A per circuit at up to 110 V. Gold-plated phosphor bronze contacts at 30.0 µin thickness run the full strip, with a push-pull fastening type that relies on friction retention rather than a locking latch. The UL94 V-0 black housing carries a 0.095 inch (2.41 mm) insulation height, and the 0.120 inch (3.05 mm) post length defines the board footprint depth for right-angle mounting.
What this means for fit and board layout
The square-post header at 0.100 inch pitch spans 36 positions in a single row. Right-angle orientation mounts perpendicular to the board edge for edge-mate stacking; the 0.120 inch post length defines penetration depth into the plated through hole, so drill size and annular ring must be confirmed against the target board thickness. The push-pull fastening has no locking clip — friction retention only. Check vibration and service disconnection requirements against the application. The contact finish supports repeated mating cycles better than tin-only alternatives — the 30.0 µin gold over the full position strip is the spec to check if cycle life is a design constraint. All 36 positions are loaded; no partial-load option is listed.
