The Amphenol FCI (FCI, now Amphenol) 87052-458HLF is a 58-position dual-row male pin header in the BERGSTIK II series — a long-standing standard at the 0.100-inch (2.54 mm) pitch for board-to-board stacking and parallel interconnect in industrial and commercial equipment. Rated 5 A per circuit at 110 V with full tin plating on both mating face and solder post (100 µin / 2.54 µm per,), the connector suits signal-duty and moderate power paths where a widely-second-sourced footprint is the primary constraint. All 58 positions are loaded — no partial-load variants in this code — and the push-pull fastening type relies on mating-side geometry rather than a locking latch; confirm your receptacle housing has adequate retention for your vibration environment.
Listed Active with no official NRND or EOL notice. No successor entry in this listing — cross-reference qualification against other 0.100-inch dual-row header families is a sourcing-side step before committing to a BOM quantity.
Through-hole solder tails accept standard 0.100-inch grid perforation; insulation height of 0.100-inch matches the board pitch, so the header sits flush with the board surface — suitable for direct socket reception or mezzanine stacking where the mating connector's housing depth is known. Unshrouded construction with square pins and phosphor bronze contact material — the BERGSTIK II footprint is the most widely cloned header geometry in the industry, which means a large pool of compatible receptacle housings and test probes from multiple manufacturers.
