What this connector is
The Amphenol BERGSTIK II 68020-164HLF is a 64-position dual-row unshrouded header rated 3A per contact at 0.100 inch (2.54 mm) pitch — a standard board-to-board interconnect in the 2.54 mm header family. Phosphor bronze contacts carry 30.0 µin (0.76 µm) gold or Gold GXT plating on the mating face, and the right-angle through-hole body sits 0.190 inch (4.83 mm) above the PCB surface with a 0.230 inch (5.84 mm) engagement depth and 0.095 inch (2.41 mm) tail length. The push-pull fastening type holds the mated pair without jack screws or latches — typical for unshrouded headers where the mating receptacle provides retention. UL94 V-0 housing rated from -65°C to 125°C covers the industrial temperature envelope.
Fit and footprint
At 64 positions in a dual-row footprint, this is the largest member of the BERGSTIK II line by circuit count. The 0.100 inch (2.54 mm) pitch and 0.100 inch row spacing fit standard 2.54 mm routing grids. All 64 positions are loaded — there is no partial-load option. The unshrouded style requires an IDC or friction-lock receptacle to provide the guide walls; a shrouded header is not the correct pair.
Line-feed reality
The 68020-164HLF ships in a bag — no tape-and-reel or tray option on this part number, which means high-volume automated placement needs to budget for manual or loose-part feeders. The right-angle through-hole termination requires a wave or hand-solder process after SMT placement; if the board assembly is all-SMT, a straight-height or bottom-entry variant would feed the line faster. Confirm the board layout accepts a right-angle entry before committing — the 0.230 inch engagement length adds to the edge clearance requirement on the mating board.
Sourcing and lifecycle
The BERGSTIK II 68020-164HLF carries an Active product status — no LTB notice, EOL, or NRND flag on file for this MPN. Quoted to order against BOM quantity; no official cross-reference or alternate MPN appears in the evidence, so confirm the AVL before building a single-source dependency into the design. The 68020 base product number is the series root — a parametric search on that base may surface lower-circuit siblings if a position-count reduction suits the application.
