It carries 80 differential pairs across 15 rows and 16 columns on a 0.053\" (1.35mm) pitch — a density that lets a single connector handle a full switch-fabric line card's worth of lanes without spreading the footprint across multiple connectors. The press-fit termination eliminates the thermal cycle and wicking risks of wave soldering, making this header a standard choice for multilayer backplanes where solder rework would compromise the board. ## Pitch and Routing — What the 0.053\" Spacing Means for the Board Layout At 0.053\" (1.35mm) pitch, the escape routing for 80 differential pairs demands a high-layer-count backplane with microvias or buried vias directly under the connector footprint. The 15-row stagger means the outer rows route through the inner layers before the inner rows — a via pattern that is standard for Impact-series backplanes but must be accounted for in the stack-up planning. The 30V voltage rating is low relative to the density; this connector is a signal-only interconnect, not a power delivery path. ## Press-Fit Assembly — No Solder, No Rework Headaches The through-hole mounting means the header is inserted from the component side and the compliant pin holds it in place — no secondary retention hardware needed for normal handling.","metaTitle":"Molex Impact 760551605 Header, 240 Pos, 0.053\" Pitch","metaDescription":"Molex 760551605 Impact header, 240 positions (80 diff pairs), 0.053\" pitch, press-fit termination, gold 30.0µin.
