The 87185-420HLF: Contacts are phosphor bronze with tin plating on both the mating face and the solder post, at 100.0 µin (2.54 µm) thickness — the full dual-side tin finish supports repeated mating cycles in a general-purpose header where cycle life is not separately specified on this listing.
Ratings profile
Current rating is 5 A per contact — this is the per-circuit ceiling at the stated temperature reference, not a derated figure, so the connector handles power distribution or signal bus duty equally within that limit. Voltage rating is 110 V, which covers most low-voltage logic-level and control-circuit applications but is not suited for mains-adjacent voltage classes.
What this connector is not
This is an unshrouded header — there is no polarizing key or foolproofing rib to prevent rotation mis-mate. The push-pull fastening type describes the contact retention mechanism, not a latching interface — confirm your mating half carries a compatible retention feature. If keyed orientation is required, the matching receptacle must carry its own keying feature or specify a shrouded variant from the same base product series.
Sourcing
Production status is Active — the 87185-420HLF is quoted to order against BOM quantities with no stated last-time-buy date on this listing. No official successor or cross-reference order code is listed in the available record; confirm with your Amphenol/Amphenol ICC representative whether a current-series variant has superseded this part number before placing a long-lead commitment.
