The TE Connectivity 1747981-1 is a 19-contact HDMI receptacle — the standard Type A pinout for consumer and industrial AV signal routing. It carries 0.5A per contact at 40VAC, which is the typical signal-level current for HDMI lanes; the 19 contacts cover the full TMDS data, clock, DDC, and hot-plug detect lines. The mounting options are unusual for an HDMI jack: panel mount with a horizontal flange, surface-mount right-angle, and through-hole all in one part number, so the same BOM line can serve a panel-bulkhead install or a PCB-edge solder-down. The gold contact finish and 10000 mating cycles mean this connector is built for frequent connect/disconnect duty — think test equipment, kiosk displays, or AV racks where the cable gets swapped regularly.
Mounting and Termination Flexibility
The 1747981-1 lists three mounting methods in one part: panel mount with a horizontal flange, surface-mount right-angle, and through-hole. That means the same receptacle can be bolted to a metal panel with the PCB sitting parallel to the face, or soldered directly to a board edge for a right-angle cable exit. The horizontal mounting feature orients the connector so the cable plugs in parallel to the mounting surface — useful when the enclosure height is tight. Termination is solder in all cases; no press-fit or IDC option here.
