The 500 mating cycles are solid for a push-pull connector: the gold-over-phosphor-bronze centre contact and gold-plated brass body resist corrosion and wear through repeated field-service reconnections. ## Obsolete — Sourcing and Cross-Reference Reality No TE Connectivity successor part number has been published for this exact 1.0/2.3 right-angle jack. For a BOM that needs this specific interface and mounting, the only sourcing path is surplus or broker inventory. Panel mount with a front-side bulkhead nut — the lockwasher prevents the nut backing off under vibration. The package includes the connector, lockwasher, and nut as three pieces.","metaTitle":"TE Connectivity 1274544-1 1.0/2.3 Jack, 50 Ohm, 10 GHz","metaDescription":"TE Connectivity 1274544-1 1.0/2.3 jack, female socket, 50 Ohm, 10 GHz, panel mount right-angle solder.
