The Amphenol FCI BERGSTIK II 87052-448HLF is a 48-position dual-row board-to-board header operating at 0.100-inch (2.54 mm) pitch. Rated 5 A per circuit at 110 V, it carries tin plating on both the mating interface and the solder post (100 µin / 2.54 µm), using phosphor bronze contacts in a push-pull unshrouded body terminated through-hole.
Fit and footprint
At 0.100-inch pitch across 48 positions in two rows, the contact span covers the stated pitch — verify routing density against your layout. The unshrouded body leaves polarisation to the footprint itself; the push-pull fastening type relies on friction-fit retention rather than a locking latch, so check whether your board stack or mating half demands a positive lock. Insulation height is 0.100 inch (2.54 mm), matching the pitch.
What 5 A and tin plating mean here
sourcing and lifecycle
Listed Active with no stated last-time-buy date or official successor. The base product number 87052 maps to the BERGSTIK II series, which includes multiple position counts and plating options — sourcing a different position count or plating from the same series is a path if this variant becomes constrained.
