What this connector is
The Amphenol 87185-133HLF is the 33-position member of the BERGSTIK II single-row header family — a board-to-board unshrouded male pin header with 0.100" (2.54 mm) pitch and through-hole solder termination. Contact material is phosphor bronze with gold or Gold GXT plating on the mating face at 30.0 µin (0.76 µm), rated 5 A per circuit at 110 V. The push-pull fastening type and square contact cross-section keep insertion straightforward in parallel board-stacking or cable-to-board panel applications where repeated mating cycles are expected.
What the ratings mean for fit
33 circuits in a single row at 0.100" pitch — confirm the board clearance and mounting hole pattern fit before committing. The 5 A per-contact rating handles signal and low-power distribution duty comfortably; the 110 V rating covers most industrial control and instrumentation bus voltages. Insulation height of 0.100" (2.54 mm) and a post length of 0.095" (2.41 mm) into the board hole define the solder-side protrusion — check your board thickness against these to ensure the tails clear the board bottom without overstressing the barrel during wave or hand solder. The housing is black with a UL94 V-0 flammability rating, which satisfies most industrial panel and equipment enclosure requirements.
Mating and sourcing
The 87185-133HLF is unshrouded and single-row — it mates with any matching BERGSTIK II single-row receptacle or IDC-style female header at the same 0.100" pitch and 33-position count. The push-pull fastening type relies on header body geometry rather than a locking latch; for high-vibration applications verify the socket housing provides sufficient friction retention or add a board-level strain-relief feature. The part is listed Active — quoted to order against the BOM quantity, no official successor or cross-reference for this 33-position variant. Confirm the mating-half position count and plating grade (gold vs tin) match your BOM line before placing the RFQ.
