Product details

BNC Jack for Panel and PCB Mount

The 031-5431-1010: The right-angle through-hole solder tails let you land the signal on the PCB while the bulkhead nut secures the connector body to the panel.

RF Performance and Contact Life

Insertion loss is rated at 0.2 dB through 1 GHz — clean enough for test equipment, instrumentation, and base station monitoring links where every tenth of a dB counts. The gold-plated phosphor bronze centre contact is good for 500 mating cycles; that puts this jack in the field-serviceable range, not a one-crimp-and-forget part.

The jack mounts through a bulkhead panel using the front-side nut and includes a lockwasher for vibration resistance. On the PCB side, the right-angle solder tails and the board lock anchor the connector against the torque of mating and unmating the bayonet plug. The dielectric is polypropylene (PP), which keeps the 50 Ohm impedance stable across the frequency range.

Frequently asked questions

Can the 031-5431-1010 be used as a direct replacement for the 031-5538-10RFX?

Electrically yes — both are 50 Ohm BNC jacks rated to 1 GHz with 500 V and 500 mating cycles. The difference is housing colour (silver and white vs black and silver) and that the 031-5538-10RFX includes the lockwasher and nut in the package. Confirm the colour and hardware requirements with your assembly drawing before substituting.
