Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete Amphenol ICC 456-102 with the active Amphenol RF 122160 is based on strict equivalence across the following critical parameters:

Connector Configuration: Both parts are TNC connector jacks with female socket type, ensuring mechanical and electrical compatibility with existing TNC plug interfaces.

Electrical Specifications: Both components maintain 50-ohm impedance and support identical termination methods (crimp contact and crimp shield), preserving signal integrity in RF applications.

Mechanical Installation: Both parts feature panel mount configuration with bulkhead front-side nut fastening and threaded attachment, enabling direct replacement in existing panel cutouts without modification.

Contact Materials and Dielectric: Both utilize phosphor bronze center contacts with PTFE dielectric material, maintaining electrical performance characteristics.

Mating Cycle Rating: Both components are rated for 500 mating cycles, providing equivalent mechanical durability.

The 122160 substitute extends compatibility to additional cable groups (RG-58A, RG-58B, RG-58C, RG-141, RG-303, LMR-195, Belden B7806A, 9907) beyond the original RG-58 specification, while maintaining full backward compatibility.
