What This HDMI 2.1 Receptacle Is
The Molex 2086581051 is a 19-contact HDMI 2.1 receptacle from the 208658 series, built for right-angle surface-mount soldering onto a PCB. It's the standard HDMI form factor — the full-size Type A — with a shielded brass shell and gold-plated contacts. The HDMI 2.1 specification means it supports the higher bandwidth needed for 48 Gbps data rates, 8K video, and enhanced audio return channel (eARC). This is the board-side half; it mates with any standard HDMI 2.1 or backward-compatible HDMI 2.0/1.4 plug cable.
Mating Cycles and Durability
That's roughly 10x the cycle life of a typical consumer HDMI port, which usually sees 1000-2000 cycles.
Electrical Ratings and Signal Integrity
Each contact is rated 0.5 A at 40 VDC. That's typical for HDMI signal lines — the connector is designed for data, not power delivery. The shielded brass shell and the HDMI 2.1 spec's tight impedance control keep the signal path clean at multi-gigabit speeds.
Termination is solder — the 19 SMT tails reflow with the board in a standard lead-free profile. The mounting feature is horizontal (right-angle), so the connector body sits flush with the board edge. The black insulation housing is UL 94 V-0 rated.
