The difference is the body finish: tin here, gold on the sibling. For an internal board-edge connection where corrosion resistance is secondary to cost, the tin body is the practical choice. The gold-finished 919-382J-51P is preferred in corrosive or high-humidity environments where the shell must resist oxidation over time.","metaTitle":"Amphenol RF 919-383J-51A MCX Receptacle, 50 Ohm, 6 GHz","metaDescription":"Amphenol RF 919-383J-51A MCX receptacle, female socket, 50 Ohm, 6 GHz max, 500 mating cycles.
