USB 3.0 20-Pin IDC Header to USB 3.0 Female Cable

Since the USB 3.0 era, motherboards grow a 19/20-pin internal header carrying two SuperSpeed ports’ worth of lanes — and this cable is how those lanes reach the outside world when no case front panel is involved. One end is the 20-pin IDC header plug that seats on the motherboard; the other is a standard USB 3.0 Type A female, so any A-male device or cable plugs in as if it had found a real port. It is the internal harness behind test fixtures, industrial panels, kiosks and embedded builds.

IDC termination means the plug grips a flat ribbon with insulation-piercing contacts — latch the header correctly and every pin lands in order, keyed so reverse insertion is physically awkward rather than silently fatal. Keep internal runs short and routed away from spinning drives and PSUs; the SuperSpeed pairs are differential and prefer tidy paths, which good internal wiring practice recommends anyway.

Key features

• USB 3.0 20-pin IDC header plug to Type A female
• Two SuperSpeed ports of lanes off one header
• Keyed IDC termination — pins land in order
• Standard A female at the far end, plug and play
• For fixtures, panels, kiosks and embedded builds

Specifications

An honest note on headers: 19-pin and 20-pin describe the same internal USB 3.0 header — one pin position is keyed/absent depending on the board maker. This plug matches the standard layout; check your header’s keying before the first seating.

Typical applications

• Bringing motherboard USB 3.0 lanes to enclosure walls
• Test fixtures and programming stations
• Kiosk and industrial PC internal wiring
