Hybrid Signal-Power Mezzanine Connector for Tight Z-Height
The Molex 5054730810 is an 8-position receptacle from the SlimStack 505473 series, designed as a board-to-board mezzanine interconnect with a mixed contact layout: 4 signal contacts and 4 power contacts in a single 2-row housing. The 0.016" (0.40mm) pitch keeps the board footprint small, while the 0.6mm mated stacking height suits ultra-slim assemblies like handheld displays, battery packs, or camera modules where the gap between stacked PCBs is under a millimeter. Gold plating on all contacts ensures reliable mating over repeated engage cycles in a corrosive-free indoor environment.
What the 0.40mm Pitch and 0.6mm Stack Height Mean for Your Layout
At 0.40mm pitch, the trace escape from the BGA-like footprint requires fine-line PCB capability — 0.20mm trace/space or tighter — and a soldering profile that avoids bridging between adjacent pads. The 0.022" (0.57mm) height above board means the component sits flush enough that a 0.6mm mated stack height is achievable with the matching header; any taller and the enclosure lid won't close.
