What this connector is and where it sits in the series
The Amphenol FCI BERGSTIK II 86837-110H is a dual-row unshrouded male pin header in the BERGSTIK II family — a long-running 2.54 mm (0.100-inch) pitch header series used as a board-to-board vertical stacking interconnect across industrial automation, instrumentation, and control card applications. This 10-position member carries two rows of five pins at 0.100-inch row spacing, with square male pins designed to mate into the matching IDC or friction-lock receptacle housing from the same series.
Key ratings and what they mean for the fit
The 0.100-inch (2.54 mm) pitch and 10-position dual-row configuration set the board footprint. The 5 A per contact current rating governs signal and low-power bus duty; at 110 V rating this header is not a power connector — keep it in the signal layer of the stack rather than routing primary power through it. Gold or Gold GXT contact plating at 30.0µin (0.76µm) thickness on the mating face gives this header good re-mating cycle durability compared to tin-plated alternatives — the thicker precious-metal deposit resists fretting and surface oxidation across multiple matings in field-service or test-fixture use. The 0.380-inch (9.65 mm) mating pin length is sized for standard board-to-board stack heights; the 0.100-inch (2.54 mm) insulation height sets the installed stacking profile. The push-pull fastening type holds the header seated without jack-screws — suitable for applications where tool-free mating is needed but vibration retention is handled by the receptacle's own latch. Phosphor bronze contact material with UL94 V-0 rated black insulation covers the material flammability requirement for enclosed equipment — the V-0 rating means the housing self-extinguishes within 10 seconds with no drip under the standard vertical burn test, which matters for industrial enclosures and any product requiring a UL94 flammability spec.
Mating half and termination
This is the male pin header — it requires the matching female BERGSTIK II receptacle housing from the same series to complete the board-to-board link. Termination is through-hole solder; the 0.120-inch (3.05 mm) post length is specified in the product drawing. All 10 positions are loaded with contacts, so every circuit in the footprint is active.
Sourcing and BOM fit check
Listed Active — the 86837-110H carries an Active product status on record. Quoted to order against BOM quantity. Confirm the position count matches your board stack requirements and that your design uses the matching BERGSTIK II receptacle housing before committing — the 0.100-inch pitch is standard across the series but shrouding and keying options vary by specific housing PN. No official cross-reference or successor code is listed for this part number.
