The crimp-style shield termination (ferrule) and crimp centre contact give a repeatable, tool-controlled termination that doesn't rely on solder skill. The nickel-plated brass body sheds corrosion in outdoor or industrial environments, while the gold centre contact keeps the signal path oxidation-free through 500 mating cycles. ## Obsolete — Sourcing Reality No official successor part number is on record. If your design can accept a parametric alternative, a current-production SMA jack with the same 50 Ohm impedance and RG-174/188/316 cable fit may be a cleaner long-term choice.","metaTitle":"TE 447648-3 SMA Jack, 50 Ohm, 12.4 GHz, Obsolete","metaDescription":"TE Connectivity 447648-3 SMA jack, 50 Ohm, crimp termination for RG-174/188/316. 500 mating cycles, 0.3 dB insertion loss.
