The 142-1801-616 is an SMA field-replaceable flange-mount socket connector designed for RF/microwave applications requiring reliable coaxial connections. It features a brass body with nickel plating (.0001 min over .00005 min copper plating), beryllium copper gold-plated contacts, and a Teflon insulator, providing excellent electrical and mechanical performance. The connector operates at 30 ohms impedance across a frequency range of 0–28.5 GHz, with a working voltage of 335 VRMS maximum at sea level and dielectric withstanding voltage of 1000 VRMS minimum. Mechanical specifications include a mating torque of 7–10 inch-pounds, coupling proof torque of 15 inch-pounds minimum, and durability rated for 500 cycles minimum. This connector is ideal for aerospace, military, and high-frequency communication systems where robust, field-replaceable RF connections are essential.
