No press-fit, no SMT reflow. The shield termination is a solder cup or through-hole solder bucket (the spec lists shield termination as solder), so the board footprint needs plated through-holes for the shield legs and the centre pin. The dielectric is PBT, which holds up to the 165°C peak without creeping. The closest peer is the 031-5329-52RFX, which is identical in every spec except the centre contact plating — that one uses gold instead of silver. For a bench or lab environment where the connector sees frequent mate cycles and the environment is clean, the silver-plated 51RFX is fine. If the jack goes into a corrosive atmosphere (salt fog, high humidity, outdoor cabinet), the gold-plated sibling gives better long-term contact resistance. Same 500-cycle life, same 4 GHz ceiling, same bayonet lock — the plating is the only decision point.","metaTitle":"Amphenol RF 031-5329-51RFX BNC Jack, 50 Ohm, 4 GHz","metaDescription":"Amphenol RF 031-5329-51RFX BNC jack, female socket, 50 Ohm impedance, 4 GHz max frequency, 500 mating cycles, through-hole solder termination.

It does not directly accept RG58 or any coaxial cable — the cable termination is done via a separate BNC plug that mates to this jack.
