What This Connector Is
The 68020-470HLF is the 70-circuit member of Amphenol FCI's BERGSTIK II dual-row header series — a 0.100 inch (2.54 mm) pitch board-to-board male pin header designed for through-hole right-angle mounting on a PCB edge. All 70 positions are populated, the contacts are phosphor bronze with 100 µin (2.54 µm) of tin plating on the mating interface, and the housing carries a UL94 V-0 flammability rating with an operating envelope of -65°C to 125°C.
Board Footprint and Mating Interface
The 0.100 inch row and mating pitch matches the standard 2.54 mm grid used across the BERGSTIK II family and most equivalent 0.100-inch pitch headers from other suppliers — the board footprint transfers directly if replacing an existing header of the same pin count and orientation. The right-angle mount seats the header parallel to the PCB surface with an insulation height of 0.190 inch (4.83 mm); the post extends 0.095 inch (2.41 mm) below the board for solder fillet formation, and the mating pin length is 0.230 inch (5.84 mm) — the longer lead provides adequate engagement depth for the matching receptacle. The header is unshrouded with push-pull fastening — no locking clip or screw tab — so the mating half must provide sufficient retention for the application. The square contact shape suits square-pin receptacles common across the BERGSTIK series.
Ratings That Drive Selection
Three amps per contact is the per-circuit rating at whatever temperature rise the housing material tolerates — the UL94 V-0 rated housing sets that ceiling, so in a 70-position all-loaded header the thermal path runs through the board and the housing. Tin plating at 100 µin (2.54 µm) is a hot-dip equivalent thickness — above the minimum required for wave-solder assembly and sufficient for multiple mating cycles in non-gold-required applications. The -65°C to 125°C operating range covers industrial and automotive board-edge environments where the connector sits unpowered on the shelf between -65°C and room temperature routinely.
