54-Position Dual-Row Receptacle for Mezzanine Stacking
The 87606-327LF: This is a 54-position, 2-row board-to-board receptacle from the Amphenol FCI Dubox series. The solder posts are tin-plated (78.7µin) for reliable wave-solder wetting. Insulation height is 0.335" (8.51mm) — the mated stack height depends on the matching header pin length.
Gold Mating Surface and Through-Hole Termination
Tin on the solder tail is standard for wave-solder processes. Through-hole termination (0.114" post length) provides stronger mechanical anchoring than SMT for a 54-position connector. This matters when the board sees vibration or when the mating header is inserted with off-axis force. The blue housing colour is consistent across the Dubox series — a visual aid during manual assembly and inspection.
Available in tube packaging. No pin-compatible equivalent or successor is listed by the manufacturer. The base product number 87606 covers the full Dubox 2-row receptacle family; position count and plating variant are specified by the suffix.
