Product details

MCX Right-Angle Receptacle for Board-Edge RF Launch

The Amphenol RF 919-383J-51A is an MCX receptacle, female socket, designed for a 50 Ohm impedance system and rated to 6 GHz.

Tin Body vs Gold-Finished Siblings

The 919-383J-51A shares the same MCX snap-on mating interface, 50 Ohm impedance, 6 GHz bandwidth, and 500-cycle durability as the gold-finished 919-382J-51P. 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.

Frequently asked questions

What is the impedance of 919-383J-51A?

The 919-383J-51A is a 50 Ohm connector, matching the standard RF system impedance.

Is 919-383J-51A equivalent to other SMP connectors?

No — the 919-383J-51A is an MCX connector, not SMP. The snap-on MCX interface is smaller and has a different mating geometry than SMP. The closest functional peer in the same base series is the gold-finished 919-382J-51P.
