It terminates via press-fit into a through-hole PCB — no solder, which means the connection is gas-tight and rework-friendly, a real advantage in backplane or high-reliability assemblies where reflow isn't an option. ## Termination and Mounting — Press-Fit Through-Hole Press-fit termination eliminates the thermal cycle of wave or reflow soldering, which is the main failure mode for plated-through-hole vias in thick backplanes. The compliant pin compresses into the plated hole and cold-welds to the barrel. That makes the 553444-4 a natural fit for assemblies where the PCB has mixed-layer stacks or where rework access is limited — you can push a damaged pin out and replace it without desoldering. The vertical orientation means the plug stands perpendicular to the board, which is the standard layout for mezzanine or cable-to-board transitions where the cable exits straight up. ## Contact Finish and Duty Cycle That thickness buys you 500+ mating cycles without exposing the nickel underplate, so this plug is specified for equipment that gets disconnected and reconnected during maintenance or reconfiguration — think telecom racks, test equipment, or industrial controllers where the cable harness is swapped out in the field. The flange feature with 4-40 threaded inserts means the mated pair can be jack-screwed together, which is the standard method for CHAMP connectors to ensure even compression across the 50 contacts and to prevent the plug from backing out under vibration. The 0.085-inch contact spacing is the series namesake: it accepts standard 0.085\" pitch ribbon cable when used with the appropriate IDC receptacle, so this plug is the board-side half of a common ribbon-cable interconnect.","metaTitle":"TE 553444-4 CHAMP .085 Plug, 50 Pos, Press-Fit","metaDescription":"TE Connectivity CHAMP .085 plug, 50 positions, 2 rows, press-fit through-hole termination, 30 µ\" gold contacts.
