The 5-1473571-4: It bridges two female connectors at a 2.00 mm pitch — useful for extending a harness or repairing a broken run without re-terminating the original connector.
The 4-position count is the BOM line check: if your harness or header has 4 circuits at 2.00 mm pitch, this adapter fits. The single-row layout keeps the adapter narrow, which helps in tight cable bundles. Pick the one that matches your circuit count.
