The Amphenol ICC 87901-460HLF is the 60-circuit member of the BERGSTIK II board-to-board header series — a dual-row, 0.100-inch (2.54 mm) pitch male pin header in through-hole solder termination. With all 60 positions loaded across two rows at 0.100-inch row spacing, this is a mid-to-high density board-stacking connector — the kind used for signal bus extensions, inter-board jumpers, and legacy I/O card-edge routing in industrial control and instrumentation equipment. Contacts are phosphor bronze with tin plating: 100 µin (2.54 µm) on the mating face and tin on the solder tail, which puts this in the economic tin-grade tier — sufficient for the 5 A per circuit rating at 110 V but below the mate-cycle longevity of gold-plated alternatives. The housing is black glass-filled nylon rated UL94 V-0, with an insulation height of 0.100 inch (2.54 mm) matching the mating pitch — so the mated stack sits flat without a protruding shoulder height above the board plane.
Board fit and stack height
At 0.100-inch pitch and 0.100-inch row spacing the footprint matches the industry-standard 2.54 mm grid used across the BERGSTIK II series and most competing 0.100-inch header families — layout熟悉的工程师可以直接套用标准2.54 mm间距的footprint规则。 The post extends 0.120 inch (3.05 mm) below the board surface with an overall contact length of 1.040 inch (26.42 mm), giving adequate lead-in length for wave or hand-soldering but no blind-mate guidance feature — alignment during mating depends on the shrouding or polarization of the mating receptacle, which this unshrouded header does not provide.
Current and voltage derating
The 5 A per contact rating at 110 V describes a single-circuit limit — at 60 loaded positions in a dense dual-row layout, the effective thermal budget of the housing constrains how many circuits you can run at full current simultaneously. Route power on the outer rows where heat dissipates first; keep the inner bus signals.
Mating half
As an unshrouded square-pin male header, the 87901-460HLF mates with any standard 0.100-inch pitch dual-row female receptacle or IDC socket in the BERGSTIK II family — verify the position count match and confirm polarization keying at the receptacle side since this header carries no integral key.
Active sourcing posture
The 87901-460HLF is listed Active — quoted to order against BOM quantities with standard lead times. No official successor or cross-reference has been published; the 60-position count and the BERGSTIK II series base number (87901) are the primary identifiers for any alternative or second-source search.
