Cable Category → Connector Fit Guide

A practical reference to help you choose connector families that fit your cable — especially when swapping between RG/LMR/Belden equivalents.

Rule of thumb: Cables in the same Category letter generally (but not always) take the same connector mechanical set — the same pin/bushing/ferrule sizes. For example, if you need connectors for Category C cables like LMR-195 or RG-122, you can usually use connector types sold “for RG-58”.

How the categories help

  • Fast matching: Find your cable’s Category, then choose connectors advertised for any cable in that same Category.
  • Cross-reference: Categories group common mechanical families across RG/LMR/Belden lines.
  • Reduced guesswork: Useful when a connector lists RG58, but you’re using LMR195 (both Cat C).

Important caveats

  • Centre conductor: Solid vs stranded can change pin fit (slit/unslit pins, drill sizes).
  • Shield build: Single vs double braid or bonded foil can nudge ferrule OD — see B2/B3 sub-categories.
  • Brand tolerances: Some series use tighter ferrule tolerances — check the connector’s specified crimp sizes.
  • Semi-rigid: L/L2/L3/L4 use different build methods (formed/soldered). Treat each L-group as its own fit family.

Cable list & categories

Cables of the same Category will generally (but not always) take the same connectors. Always check centre conductor and shield construction.

Buying checklist

  • Category match: Choose connectors that list any cable in your Category.
  • Pin size: Check pin ID vs cable centre conductor (solid/stranded gauge).
  • Ferrule size: Match ferrule ID to your cable’s braid/foil OD (watch double-braid variants).
  • Assembly method: Crimp vs solder vs clamp per connector series and your tools.
  • Semi-rigid: Use L/L2/L3/L4-specific parts and methods.

FAQs

Do RG58 and LMR-195 use the same connectors?

Usually yes (Category C). Always confirm pin ID and ferrule size against your cable datasheet, especially if your cable is stranded or double braided.

What if my cable is double braided?

Match the sub-category (e.g., B2/B3) because the required ferrule ID can differ from single-braid variants.

Can I mix semi-rigid cables within a Category?

Treat L/L2/L3/L4 as separate fit families. Semi-rigid assemblies often require formed/soldered parts and specific tooling.

Which connectors should I stock for Category C?

SMA, N-Type and TNC families are the most common. Use our Cat C sections above to filter for RG58/LMR195 parts.

Note: The Category system is a practical guide for mechanical compatibility. Always confirm exact dimensions on the connector datasheet before purchase, particularly for double-braided and semi-rigid cables.
