The 15 µinch gold mating finish supports field-service reconnect duty without contact fretting.
Both are 2-position KK254 unshrouded headers on 2.54 mm pitch. The difference is the plating: 0022284023 has gold on the mating face (15 µinch) and tin on the post; 0022284024 is all-tin. For applications with frequent mating cycles or corrosive environments, the gold version (0022284023) is the better choice.
Yes — Automotive is listed among the intended applications. The UL94 V-0 housing and gold mating finish suit the vibration and temperature range of non-sealed interior automotive modules. For underhood or wet locations, a sealed connector family would be required.
