The 86832-144HLF: Gold-over-nickel plating at 30.0µin (0.76µm) on the mating interface sits at the upper end of the BERGSTIK II gold-plating range, giving the contact longevity against fretting in applications where the header sees repeated mating cycles. The push-pull fastening type means the board-to-board stack is held by contact normal force alone — no separate locking latch — so board flex under vibration can work the contacts loose in high-vibration environments without secondary strain relief on the stack.
What the ratings mean for your BOM line
44 positions is the primary fit check — the circuit count must match the netlist or harness drawing exactly, since BERGSTIK II headers are not typically supplied in removable contact versions that would let you populate a subset of positions after assembly. The pitch (0.100" / 2.54mm) and row spacing (0.100") confirm the footprint class — two rows on the same grid pitch as the industry-standard 0.100-inch headers, so a board designed for a 2-row 2.54mm header will take this part without pad rework. 5 A per contact at 110 V frames this as a power-rated board-to-board header — the voltage is modest compared to the 600V class seen in some industrial headers, so verify the system bus voltage is within 110 V before committing. The phosphor bronze base material and gold finish on the mating side support the current density; the 30.0µin (0.76µm) gold thickness is durable for repeated matings in field-service scenarios, but the header is not specifically rated for high-cycle instrumentation use above several hundred cycles.
Active production — sourcing against the BOM
86832-144HLF is listed Active with no announced end-of-life on record. Quoted to order against the BOM quantity — no official successor or cross-reference entry on file. The 44-position count and the 0.100" pitch are the definitive fit criteria: confirm the netlist circuit count and the board hole/pad pattern before placing a PO. The Amphenol FCI BERGSTIK II series is a long-running product line, so alternate positions within the same series are usually available from the same manufacturing source to cover adjacent BOM positions.
