Each of the two power positions is rated 20 A continuous. In a 2-position connector, that gives a total current capacity of 40 A across the pair, assuming proper derating for ambient temperature and conductor size. The post finish is gold flash, which is typical for SMT solder joints. Voltage rating is 100 VDC — suitable for low-voltage power distribution in equipment, not for mains or high-voltage bus bars. ## Comparing to the 10-position sibling The closest functional alternative within the same base number is 10159561-A00221RLF — a 10-position (power) version with the same 20 A per contact rating, same 2.00 mm pitch, same detent lock, and same gold plating. The key difference is circuit count: 2 positions vs 10 positions. If your BOM needs more than two power circuits, the 10-position sibling saves board space versus ganging multiple 2-position connectors.","metaTitle":"10159561-200121RLF PowerStak® 2-Position Receptacle, 20A","metaDescription":"Amphenol ICC (FCI) PowerStak® 2-position female blade socket receptacle, 20A per contact, 2.00mm pitch, SMT, detent lock, gold plating.
