What this connector is
The Molex 78216-1001 is a 4-position, 2-row power blade receptacle in the Impact 78216 series — it accepts the matching male blade header and is designed for board-level power distribution rather than wire termination. Each of the four circuits carries 25 A at up to 250 V, which puts it well into mid-power territory for a blade-style interconnect. The press-fit tails eliminate solder: the connector seats into plated through-holes under controlled press force, so the PCB must be sized for press-fit insertion rather than wave or reflow assembly.
Gold plating and what it means here
Contacts are gold-plated at 30.0 µin (0.76 µm) — that thickness is meaningful because it supports repeated mating cycles without the fretting risk that thinner tin finishes carry on power blades. For a connector delivering 25 A per circuit, the plating grade, not just the current rating, is what governs long-term contact resistance under load.
Operating envelope
The operating range spans -55°C to 85°C, and the housing carries a UL94 V-0 flammability rating — suitable for industrial enclosures and equipment where flame retardance is required by the end-product standard. The black housing colour is listed as a series attribute; confirm against the BOM colour callout if the assembly has a specific aesthetic or safety-marking requirement.
Lifecycle and sourcing
The 78216-1001 carries an Active product status and is ROHS3 Compliant. It is quoted to order against BOM quantity; confirm the press-fit tooling compatibility with your board manufacturer before committing the position to the layout. No official successor order code appears on record for this member — if the BOM calls for a pin-compatible alternative within the series, that cross-reference must be verified directly with Molex or the franchise distributor.
