Common Coaxial Cable Groupings for Connector Compatibility
Many RF connectors are designed to fit multiple coaxial cable types that share similar jacket diameters, dielectric diameters, and braid dimensions.
The chart below shows the most common cable groupings used when selecting connector sizes for crimp, clamp, solder, compression, and RF adapter applications. This is intended only for general guidance, you should ensure the specs match to the connector you are desiring to use. See our Coax Cable Table for more information.

Important Practical Notes
- RG-142 and RG-400 almost always use the exact same connector family.
- LMR-195 and LMR-200 generally use RG-58 size connectors.
- RG-223 often fits RG-58 connector bodies, but some crimp ferrules may differ because of the double shield construction.
- LMR-240 generally uses RG-8X connector sizing.
- RG-214 usually uses RG-213 style connectors, although some connectors require larger ferrules due to the double braid shield.
- LMR-400 and Belden 9913 commonly share connector families, but exact fitment may vary because 9913 uses an air-space dielectric.
- Foam dielectric cables such as LMR series may require different center pin dimensions compared to solid dielectric RG cables.
-
Always verify:
- Center conductor diameter
- Dielectric diameter
- Shield diameter
- Jacket diameter
- Connector manufacturer compatibility chart
