Product details

DVI-I Dual Link Receptacle — 29-Pin, Right-Angle, Shielded

The Molex 743201003 is a DVI-I Dual Link receptacle from the MicroCross 74320 series, carrying 29 contacts in a single port. It accepts both digital (TMDS) and analog (RGB) video signals, making it the universal DVI connector that mates with DVI-D, DVI-A, and DVI-I cables. A steel shield surrounds the contact area to contain EMI from high-speed digital video lanes up to dual-link bandwidth.

Pinout and Compatibility — DVI-I vs DVI-D vs DVI-A

The 29-contact layout is the DVI-I dual-link pinout: 24 digital pins arranged in three rows (C1–C5 for analog, the rest for TMDS data and clock), plus the four analog pins (C1–C5) and the flat blade for the analog sync. The extra five contacts over a DVI-D connector (24 pins) are the analog RGB and horizontal/vertical sync lines. This receptacle accepts a DVI-D plug (digital only) or a DVI-A plug (analog only) — the analog pins simply go unused with a DVI-D cable. It will not accept a DVI-I single-link plug (which has only 24 pins in a different layout) because the dual-link pinout adds the extra TMDS lanes in the centre row. The keying on the DVI-I connector is a four-pin flat blade on one side; the DVI-D connector has a single flat blade. Both mate physically, but the analog pins are only present on the DVI-I receptacle.

Each contact is rated 3A at 40VAC, which is typical for signal-level DVI — not a power connector. The 40VAC rating covers the analog video signals (RGB lines run at a few volts) and the +5V DC supply for the monitor's EDID chip.

Mounting and Termination — Right-Angle Solder to PCB

The 743201003 terminates via solder tails to a PCB — no crimp, no IDC. The right-angle body positions the receptacle parallel to the board, with the horizontal flange providing panel-mount stability through two mounting holes (M3 screws typical). The 100 mating cycles are adequate for field service and occasional cable swaps but not for daily hot-plugging — the gold-plated contacts resist fretting corrosion over those cycles.

No official replacement or cross-reference exists within the series — the 29-contact DVI-I dual-link pinout is unique to this order code.

Frequently asked questions

What is the pinout of the 743201003 DVI-I dual link connector?

The 743201003 has 29 contacts arranged as a DVI-I dual-link pinout: 24 digital TMDS pins (three rows of eight), plus four analog RGB and sync pins (C1–C5), and a flat blade for the analog sync. The digital pins carry the dual-link TMDS data lanes, while the analog pins carry the RGB and H/V sync signals. The pinout is standard per the DVI specification — pin 1 is TMDS data 2-, pin 24 is TMDS data 2+, and the analog pins are C1 (red), C2 (green), C3 (blue), C4 (horizontal sync), C5 (vertical sync).

Is 743201003 compatible with DVI-D or DVI-A?

Yes — the DVI-I receptacle accepts both DVI-D plugs (digital only) and DVI-A plugs (analog only). With a DVI-D cable, the analog pins simply go unused. The keying is the same flat blade on one side, so a DVI-D plug mates physically. A DVI-I single-link plug (24 pins) will not mate because the dual-link pinout adds extra TMDS lanes in the centre row — the plug's keying is different.
