What this connector is
The Molex 78234-2001 is a 2-position, dual-row right-angle press-fit header in the GbX I-Trac 78234 series, rated 80 A per circuit at 250 V with gold-plated contacts (30.0 µin / 0.76 µm).
80 A on 2 positions — what that means for the design
The 80 A per-circuit rating on a 2-position header is the defining spec here. This is a mid-plane or backplane power distribution connector, not a signal header — the current density per circuit is far above what a generic header carries. Confirm the de-rating curve against your actual operating temperature when designing to the 80 A ceiling; the -20°C to 85°C operating window bounds the usable range. Gold plating at 30.0 µin (0.76 µm) is a thick, durable finish suited to multiple mating cycles and to carrying sustained current without the contact resistance creep that thin tin platings develop under load. If this is a field-reconnect node, the plating grade supports it; if it is a permanent mid-plane bond, the gold is overhead that the budget tolerates.
Press-fit termination and board-edge mounting
Press-fit termination means the contacts are pressed into plated-through holes — no solder required at the press-fit interface, which makes it compatible with mixed soldering processes (wave or reflow for adjacent SMD) and allows the connector to be installed after paste/reflow if the board assembly sequence demands it. The right-angle orientation and board-edge mounting type mean it sits at the card perimeter, feeding power in from the edge of a backplane or mid-plane board into daughter cards or bus bars. The I-Trac Hold Down Right style and the board-guide feature on the housing provide lateral retention and alignment during insertion — relevant for rack-level assembly where vibration or thermal cycling could shift a poorly guided edge connector over time.
Sourcing and compliance
The 78234-2001 is Active and ROHS3 Compliant — it commits to a standard industrial BOM without a compliance flag. The housing is UL94 V-0 rated, which is the minimum flame-class requirement for industrial and most telecom equipment enclosures. No UL or VDE rating is listed for the connector itself; if your system-level certification requires connector-level UL recognition, confirm that against the product drawing before quoting. No official successor or cross-reference order code is listed for the 78234-2001. The GbX I-Trac 78234 series spans multiple position counts; if your BOM requires a larger circuit count within the same press-fit right-angle format, check the series ladder — but the 2-position member (78234-2001) is the seed for sourcing decisions here.
