Board-to-Board Mezzanine Header, 80 Positions, 0.80 mm Pitch
The B4061B7L111280E100 is an 80-position header from the B4061B7L series, designed as the plug half of a board-to-board mezzanine interconnect.
With a height above board of 0.346" (8.80 mm), this plug mates with the matching receptacle (B4101B7L111280E100, 18.21 mm height) to set the total mezzanine gap. The 0.80 mm pitch demands tight trace routing — keep-out zones around the SMT pads are worth checking against the PCB stack-up before layout lock.
Contact Plating and Mating Duty
Gold flash plating at 2.00µin (0.051µm) is specified for this header.
The B4061B7L series offers 60-position (B4061B7L111260E100) and 90-position (B4061B7L111290E100) siblings at the same 0.80 mm pitch and 8.80 mm stack height. The 80-position version here splits the difference — pick the count that matches your signal I/O without leaving unused circuits.
RoHS compliant.
