It is a panel-mount bulkhead connector with a bayonet lock, using a rear-side nut for installation. The connector comes as a kit including the jack, one lockwasher, and one nut — everything needed for a single panel feed-through. The centre contact is beryllium copper with silver plating, terminated via a solder cup. The shield connects through a solder tag on the body. The dielectric is PTFE, and the brass body has a nickel finish. Rated for 5000 mating cycles, it suits test equipment, instrumentation, or any application requiring frequent connect/disconnect. The silver-plated centre contact offers low resistance but may tarnish in corrosive atmospheres — consider gold-plated alternatives for harsh chemical exposure. ## Lifecycle Status — Last Buy, Sourced to Order The Hirose UG-625/U-4(40) carries a Last Buy lifecycle status. This means the manufacturer has discontinued production, and remaining stock is limited. No official replacement order code is on record from Hirose; any substitute would need to be evaluated for fit, impedance, and frequency performance. ## Termination and Installation — Solder Cup and Solder Tag The centre contact uses a solder cup termination — strip the centre conductor, tin it, and solder into the cup. The shield braid or drain wire is soldered to the solder tag on the body. This is a field-terminable connection, though it requires a soldering iron and steady hands. The lockwasher and nut secure the connector to the panel from the rear; the bayonet lock provides quick mating with a male BNC plug. ## RF Performance — 50 Ohm, 4 GHz Bandwidth This BNC jack has a 50 Ohm impedance and a maximum frequency of 4 GHz.","metaTitle":"Hirose UG-625/U-4(40) BNC Jack, 50 Ohm, 4 GHz, Last Buy","metaDescription":"Hirose UG-625/U-4(40) BNC jack, 50 Ohm, 4 GHz max, silver-plated beryllium copper contact, solder cup termination, includes lockwasher and nut.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["RF / Coaxial Connectors"],"specifications":{"Mfr":"Hirose Electric Co Ltd","Series":"-","Package":"Bulk","Features":"-","Includes":"3 pcs - 1 Connector, 1 Lockwasher, 1 Nut","Impedance":"50 Ohms","Body Finish":"Nickel","Cable Group":"-","Body Material":"Brass","Housing Color":"Silver","Mating Cycles":"5000","Mounting Type":"Panel Mount","Connector Type":"Jack, Female Socket","Fastening Type":"Bayonet Lock","Insertion Loss":"-","Product Status":"Last Time Buy","Connector Style":"BNC","Frequency - Max":"4 GHz","Number of Ports":"1","lifecycle_stage":"unknown","Mounting Feature":"Bulkhead - Rear Side Nut","Ingress Protection":"-","Shield Termination":"Solder Tag","Base Product Number":"UG-625/U","Contact Termination":"Solder Cup","Dielectric Material":"Polytetrafluoroethylene (PTFE)","Operating Temperature":"-55°C ~ 85°C","Center Contact Plating":"Silver","Center Contact Material":"Beryllium Copper"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/7eca5fdc3100f922e8521b47944e9d5b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is UG-625/U-4(40) obsolete?","answer":"The UG-625/U-4(40) is in Last Buy status — production has ended, but limited stock may still be available.
