The 57102-G06-25LF: In a typical board-to-board link carrying logic-level signals, the 2 A limit is generous; the real constraint is the trace width on the PCB. Fine for a single connector pair in a jigged assembly; risky in a multi-connector panel where a mis-mate could short adjacent pins.
Gold GXT™ Mating Surface — 30 µinch Plating Depth
No compatibility issue with lead-free or tin-lead solder processes.
RoHS Compliant per the manufacturer declaration. The UL94 V-0 rating is a material-level approval, not a full UL listing for the connector assembly — confirm with the factory if a UL Recognized component mark is required for your end-equipment certification.
