Hybrid Power-Signal Connector for Backplane Assembly
The Molex 0461148200 is a 28-position receptacle from the EXTreme LPHPower 46114 series, a hybrid connector family that consolidates signal and power circuits into a single housing. Its contact layout — 20 signal positions and 8 power positions — lets one connector handle both a data bus and a DC power feed, reducing the number of separate connectors on the board edge. Termination is press-fit through-hole, which means the contacts are pressed into plated holes without solder.
Press-Fit Termination and Guide Pin for Blind-Mate Reliability
The press-fit termination eliminates the solder joint, which is the most common failure point in high-vibration backplane applications. The compliant pin compresses into the plated through-hole and holds by interference fit — no reflow profile, no flux residue, no cold joint. This also means the connector can be replaced in the field with a simple insertion tool. An integrated guide pin is molded into the housing. When mating the receptacle to its header counterpart, the guide pin engages first and aligns the contact rows before the signal and power pins touch. This prevents stubbing or bending a contact during blind mating — a common failure when the connector is buried deep in a chassis or backplane. The 2-row layout with 28 total positions splits into a 20-signal / 8-power arrangement. The power contacts are physically larger and carry higher current, while the signal contacts are standard-density. The board footprint must accommodate both the signal via field and the larger power via pads — the manufacturer's application note specifies the recommended hole and pad sizes for each contact type.
Active Lifecycle and Sourcing
The 0461148201 is a sibling in the same series but carries a different contact layout or feature set — verify the position count and power/signal split before substituting.
