FK0MDG Equivalent & Substitute Parts

Part Overview

The FK0MDG is an SMB Fakra Connector Plug manufactured by Taoglas Limited, designed for RF coaxial applications requiring 50 Ohm impedance. This connector features a male pin configuration with crimp termination for both contact and shield, operating across a frequency range up to 6 GHz. The part is actively produced and maintains ROHS3 compliance with REACH unaffected status. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate additional suppliers.

Substitute Part Grouping Explanation

Substitution of coaxial RF connectors is determined by strict equivalence across electrical and mechanical parameters. The FK0MDG and its identified substitute FK0MDDK share identical specifications across all critical parameters that govern connector interchangeability:

Electrical Parameters: Both parts maintain 50 Ohm impedance and support identical frequency ranges up to 6 GHz, ensuring signal integrity and performance equivalence in RF applications.

Mechanical Parameters: Both connectors employ identical SMB Fakra connector styles with male pin configurations, crimp termination methods for both contact and shield, and free hanging in-line mounting. The locking ramp fastening type and Code D feature designation are consistent across both parts.

Environmental & Compliance Parameters: Operating temperature ranges, mating cycle ratings, RoHS3 compliance, and REACH status are identical, confirming suitability for equivalent applications.

Cable Compatibility: Both parts support RG-174 and RG-316 cable groups, maintaining consistent integration with standard RF cabling infrastructure.

Substitution is valid when the application requires a Fakra Code D male plug connector with 50 Ohm impedance, crimp termination, and free hanging mounting for frequencies up to 6 GHz.
