The 89892-330LF: This is a 60-position, dual-row board-to-board receptacle from the Amphenol ICC Dubox series. The connector accepts a mating pin header with the same pitch and row spacing — a straightforward fit for backplane or mezzanine stacking where the board-to-board gap is set by the header's post height.
The connector mounts through hole with a 0.118" (3.00 mm) post length — this tail length suits standard 1.6 mm thick PCBs with enough protrusion for wave-solder fillet formation. Bottom or top entry allows the receptacle to be loaded from either side of the board, depending on the assembly sequence.
