What This Connector Is
The FCI (Amphenol) 57102-F06-10ULF is the 20-circuit member of the Minitek® 2.00mm board-to-board header series. It is a dual-row unshrouded male pin header rated 200V AC/DC with 2A per circuit, through-hole push-pull mounting — the push-pull fastening type means it mates with a matching friction-lock receptacle rather than a latch or screw. The 2.00mm pitch puts this in the mid-density signal class — dense enough for multi-signal board-stacking in industrial controls and instrumentation, not a power-delivery header. The dual-beam square-pin contact and 0.157" (4.00mm) mating length provide stable insertion in mezzanine or perpendicular board-to-board orientations.
Plating, Current, and What the Ratings Mean
Gold-flash on the mating interface is the right finish for the mating face — it resists fretting on low-current signal contacts and survives dozens of mating cycles without the lifecycle hit that tin-on-mating would take. The solder-post side is tin-plated at 78.7 µin (2.00 µm), which is standard for through-hole wave or hand-solder board assembly. The 2A per circuit rating at 2.00mm pitch is a signal-density rating for board-to-board routing — the 2.00mm pitch and contact cross-section are sized for low-current signal paths, not power delivery. The housing is black thermoplastic rated UL94 V-0, which clears the flammability requirement for most industrial and commercial equipment enclosures. With no sealing or keying spec on this open-style header, it is for protected board-level interconnects — not for equipment exposed to moisture or dust without enclosure sealing.
Typical Applications
Board-to-board stacking in industrial automation, instrumentation, and consumer electronics — the perpendicular or mezzanine configuration where two PCBs need a reliable low-current signal bus. The through-hole mounting provides mechanical retention under shock and vibration better than SMT alone; the dual-row layout suits data buses, control signal routing, and low-speed sensor aggregation.
