What this connector is
The Molex 755615000 is a 2-position dual-row male-blade power header in the EXTreme PowerMass 75561 series — a connector family built for high-current bus-bar and PCB power distribution at the board level. Rated 80 A per circuit at 450 V, it carries enough current to handle primary power bus segments in industrial drives, server PSUs, and similar high-amp distribution points where the alternative is a soldered bus bar or a larger discrete terminal. The right-angle through-hole form factor lets it drop a power bus flat onto a PCB plane, and the press-fit termination keeps the current path solder-free — no reflow profile risk, and the press-tail gaslights the joint mechanically without relying on solder fillet integrity under vibration.
What the ratings mean
80 A per circuit is the per-contact current ceiling — at the high-current end of a power distribution stack the 80 A figure governs wire gauge and bus-bar sizing on the mating side; derate above 105 °C per the product thermal data. 450 V is the dielectric voltage rating — that covers the AC and DC bus voltages typical in industrial three-phase and server PSU power rails up to that level. Gold plating at 30.0 µin (0.76 µm) over the contact surface means the mating interface has the corrosion resistance and low contact resistance needed for a high-amp connection that will see thermal cycling and extended dwell time mated — tin-plated alternatives in this current class are more prone to oxidation-induced resistance creep at the interface over life. UL94 V-0 flammability rating on the housing means the connector body self-extinguishes within the standard vertical burn test window — important for enclosed equipment where the power distribution stack sits inside a restricted airflow cavity.
Sourcing and lifecycle
The 755615000 is listed Active with ROHS3 Compliant status — no lifecycle risk on record, and it carries the full RoHS3 qualification, so it clears the environmental compliance checklist for most industrial and infrastructure end equipment without additional qualification runs.
What it mates with
The 755615000 is the male-blade press-fit header — it mates with the matching EXTreme PowerMass 75561 series female receptacle housing (crimp or solder termination, ordered separately) that carries the same 2-position contact layout and current rating. Press-fit termination requires a plated-through PCB hole sized to the press-tail dimensions — confirm the recommended hole diameter from the product drawing before committing the board layout, since a mis-sized press-fit hole either won't accept the tail or won't hold it.
