HDMI Receptacle, 19 Contacts, Vertical SMT — 10,000 Mating Cycles
The Molex 476591102 is a 19-contact HDMI receptacle from the 47659 series, designed for vertical surface-mount assembly on a PCB. It carries a full metal shield for EMI containment — standard for HDMI signal paths — and gold-plated contacts rated at 0.5 A per contact. The 10,000-cycle mating life is well above the typical consumer HDMI jack (often 5,000 cycles), making this a candidate for equipment that sees repeated cable swaps: test fixtures, panel-mount display ports, or industrial HMI panels where the cable gets unplugged daily.
The shielded shell (brass alloy) mates with the cable-side HDMI plug's outer contact to create a continuous ground plane around the differential pairs. This is not optional for HDMI compliance above 1080p — without the shield, the radiated emissions and common-mode noise from the TMDS clock lines will fail an FCC pre-scan. The vertical orientation keeps the signal path short to the PCB traces, which helps maintain the 100-ohm differential impedance through the connector.
Mounting and Assembly
Listed for both Surface Mount and Through Hole mounting, but the vertical orientation and SMT pads are the primary fit. The board guide and pick-and-place features tell you this was designed for automated assembly — the pick-and-place pad gives the nozzle a flat target, and the board guide aligns the connector during reflow so the shield tabs don't skew. The through-hole option likely refers to the shield anchor legs that get soldered into plated through-holes for mechanical retention, not the signal contacts.
