Single-position power receptacle for backplane and busbar distribution
The TE Connectivity 6643269-1 is a single-position power receptacle from the ICCON, Elcon series, designed to carry 35 A at 250 V through a press-fit termination into a PCB. That 35 A per contact means this isn't a signal line — it's sized for a DC power rail or busbar interconnect where you need a reliable, solderless connection. The press-fit termination suits backplane assemblies where rework or field replacement is a consideration, since there's no solder joint to crack or reflow.
Press-fit vs solder — what the termination choice means for your build
The 6643269-1 uses press-fit termination, which sets it apart from the sibling 6643264-1 that uses solder tails. Press-fit avoids the thermal stress of wave soldering and makes the connector field-replaceable if a contact ever needs swapping. The trade-off is that the PCB hole size and plating must match the press-fit compliant pin spec — something to confirm against your board house's capability. Both carry the same 35 A and 250 V ratings, so the choice comes down to assembly method and serviceability.
Silver plating at 200.0 µin — built for power cycling and repeated mates
The contact finish is silver at 200.0 µin (5.08 µm) — a thick layer that handles the current density of 35 A without the galling risk you'd see with thinner platings. Silver is the standard choice for power contacts because its conductivity stays low-resistance under load, though it will tarnish in corrosive environments.
