142-1801-571 is an SMA field-replaceable flange-mount socket connector designed for RF applications requiring high reliability and durability. The connector features a brass body with gold plating (0.00001 inch minimum) over nickel and copper, paired with beryllium copper contacts similarly gold-plated, and a TFE/LON insulator for excellent electrical performance. It accommodates a 0.018-inch diameter pin with a maximum depth of 0.10 inches and maintains a flange body dimension of 0.375±0.010 inches. The connector is rated for RF high potential withstanding voltage of 670 VRMS minimum at 4 and 7 MHz, with a mating torque range of 7–10 inch-pounds and a minimum durability of 500 cycles. Operating over a temperature range of -65°C to +165°C and meeting MIL-PRF-39012 environmental standards, this connector is ideal for aerospace, military, and high-frequency communication systems where field replaceability and robust performance are essential.
