Bottom or top entry means the same receptacle can sit on the PCB with the mating header coming from either side — useful for mezzanine stacking where the board-to-board height is fixed by the enclosure.
Housing Material and Flammability Rating
Glass-filled thermoplastic rated UL94 V-0 — the housing won't sustain a flame in equipment that requires a flammability rating. The gray insulation body stands out against a green PCB, which helps visual inspection after soldering.
Where This Fits in the Dubox™ Series
Dubox™ is Amphenol ICC's 0.100" pitch, dual-row socket header family. At 68 positions, this is one of the higher-circuit-count members — useful for wide data or control buses where a single connector replaces two smaller ones. The 30 µinch gold mating finish is the standard production grade; the tin-plated solder tails (78.7 µinch) are compatible with lead-free wave solder profiles.
