HDMI 2.1 Receptacle for High-Bandwidth Video Interfaces
The Molex 2086588131 is a shielded HDMI receptacle from the 208658 series, designed to the HDMI 2.1 specification. It carries 19 contacts in a right-angle surface-mount package, with the connector body oriented horizontally to the board edge. Gold-plated contacts and a brass shell handle the signal integrity demands of 48 Gbps HDMI 2.1 links, while the 10000-cycle mating rating puts this well above a typical consumer HDMI jack — it's specced for equipment that sees frequent cable swaps, like test fixtures, AV switchers, or commercial displays.
What the 10000 Mating Cycles Mean for Your Build
At 10000 cycles, this receptacle is built for a decade of daily plugging in a lab or production environment. If your application involves a cable that gets swapped weekly or monthly — think a calibration station, a video wall input panel, or a test rack — this is the right endurance class.
Board Layout and Assembly Considerations
The mounting type supports both SMD and through-hole variants, though this specific order code is the SMD version. The 19 contacts are on the standard HDMI pitch — no footprint surprises if you're replacing an older HDMI 1.4 or 2.0 receptacle on the same board layout. The brass shell provides the grounding path and EMI shielding; ensure your PCB ground plane connects to the shield tabs with adequate thermal relief for reflow soldering.
HDMI 2.0 and 2.1 Compatibility
Yes, the 2086588131 is backward-compatible with HDMI 2.0 sources and cables. The HDMI 2.1 specification defines the electrical and mechanical interface, but the connector itself — 19 contacts, same shell dimensions, same pinout — will pass HDMI 2.0 signals without issue. The higher rating just means it's certified to handle the 48 Gbps data rate of HDMI 2.1 when the rest of the system supports it. There is no pinout difference between HDMI 2.0 and 2.1 at the connector level.
