Obsolete 1.0/2.3 Coaxial Jack — Sourcing and Fit
The 3-1393670-9: This is the receptacle side — it mates with a 1.0/2.3 plug (male) connector. There is no listed direct replacement from TE Connectivity. The 1.0/2.3 interface is not compatible with SMA or BNC connectors; it is a distinct coaxial standard used primarily in European telecom and test equipment.
Signal Path — 50 Ohm, 10 GHz Ceiling
The 10 GHz maximum frequency covers L-band, S-band, and lower C-band signals. The PTFE dielectric keeps insertion loss stable across the band.
Procurement Bottom Line
This is a last-time-buy or surplus-only part. No official replacement exists. Confirm the mating plug interface before committing the line.
