The Molex 743204004 is a DVI-D dual link receptacle from the MicroCross 74320 series. It carries 24 contacts in a single shielded shell, rated 3A per contact at 40VAC. This is the full-bandwidth dual link variant — all 24 pins are populated, supporting resolutions up to 2560x1600 at 60 Hz over a single cable.
Single Link vs Dual Link — What the 24 Contacts Mean
A DVI single link connector has 18 contacts (12+6) and tops out at 1920x1200 at 60 Hz. The 743204004's 24-contact dual link layout adds six extra high-speed data pairs, doubling the TMDS channel count. That extra bandwidth is what drives higher resolutions and refresh rates. If your BOM calls for dual link, a single link receptacle won't seat the full pin complement — the plastic keying is different between the two, so they physically won't mate. This part is the dual link version, confirmed by the 24-contact count and the DVI-D designation.
Panel mount, through hole, right angle — the connector bolts to the panel via the flange, and the 24 solder tails go through the PCB. The horizontal orientation means the PCB sits vertical relative to the panel face, which is the typical layout for a video port on a card edge.
