The 2307706-5: Each contact is rated 2 A, with a gold mating finish at 15.0 µinch thickness — adequate for moderate reconnect cycles in signal-level circuits.
The 1376775-2 uses a copper alloy contact with 8.00 µinch gold, while the 2307706-5 uses phosphor bronze with 15.0 µinch gold — the thicker gold here improves corrosion resistance for field-service environments.
