The 79257-454HLF: With all 54 positions loaded and a 3 A per-contact rating, this header handles up to 162 A total across the connector — but the practical limit is set by the PCB trace width and ambient temperature, not the header itself.
The 0.230" (5.84mm) mating pin length provides good wipe for reliable contact, while the 0.120" (3.05mm) solder tail length suits standard 1.6mm PCBs.
Yes, the 79257-454HLF is RoHS compliant. The tin plating and phosphor bronze contacts meet the directive's substance restrictions.
