Cable Fit and Termination — RG-174, 188, 316 Double Braid

The 413985-4: This plug is designed for RG-174, RG-188, and RG-316 double-braid cable groups. The contact terminates by crimp or solder; the shield crimps over the ferrule. The PTFE dielectric handles the temperature range and keeps impedance stable through the termination. If you're working with RG-316, this plug is a direct fit.

Cross-Shop: 415218-1 as a Functional Alternative

If 413985-4 is on allocation, the 415218-1 is a direct functional peer — same SMB plug, female socket, 50 Ohm, bulk package, active lifecycle. The key difference is the cable group: 415218-1 may target a different cable type. Confirm your cable fit before swapping.
