The Molex 464369314 is the 19-circuit member of the EXTreme Ten60Power 46436 series, a hybrid receptacle that packs 15 signal contacts and 4 power blades into one black UL94 V-0 housing. Each power contact is rated 60 A. The 15 signal contacts handle control and feedback lines. Termination is press-fit, so this receptacle presses into plated through-holes without solder — a clean assembly for backplane or midplane designs where rework access is limited and solder-joint reliability under thermal cycling is critical.
That plating thickness supports repeated mating and unmating in a production or field-service environment without the contact resistance drifting — it is not a one-time crimp-and-forget connection. If your application sees frequent board swaps or harness changes, the gold grade is the spec that keeps the connection stable. The voltage rating is 600 VAC and 250 VDC — the AC rating is higher because the waveform crosses zero every half-cycle, which helps extinguish any incipient arc. The DC rating is the tighter limit: if you are switching or hot-plugging a DC bus, stay under 250 VDC. For steady-state DC distribution at lower voltages, the 600 VAC rating gives plenty of headroom for isolation.
The closest functional peer in the same series is the 464369313 — an 18-position hybrid receptacle with the same 60 A power contacts, same 30.0 µin gold plating, same press-fit termination, and same right-angle orientation. The difference is the contact layout: the 464369314 carries 15 signal + 4 power (19 total), while the 464369313 carries 15 signal + 3 power (18 total). That one extra power blade on the 464369314 gives you an additional 60 A of current-carrying capacity in the same housing footprint — the board layout and keep-out zone are identical, so swapping between them is a BOM-position decision, not a board-spin decision.
