What This Strain Relief Does
The TE Greenpar 5-1478996-6 is a black PVC strain relief boot — an accessory, not a connector itself. It fits over the cable entry of BNC, N Type, TNC, and UHF connectors to take the mechanical load off the crimp or clamp joint. Water finds the open splice; this boot seals the cable-to-connector transition and keeps the braid from fraying at the back of the shell. The PVC body gives it enough flex to work in tight cable bends without cracking, and the black color helps identify it in a crowded panel.
Fit Check — Which Connectors It Goes On
Designed for BNC, N Type, TNC, and UHF connector families — the common 50- and 75-ohm coaxial interfaces used in RF test, broadcast, telecom, and antenna systems. This is a boot that slips over the connector body after the cable is terminated; it does not change the electrical interface. If you are replacing a cracked or lost boot on an existing assembly, confirm the cable diameter and connector backshell profile match the boot's internal dimensions from the product drawing.
Lifecycle Status — Obsolete, Sourced to Order
TE has marked the 5-1478996-6 as Obsolete. No official successor part number is listed. If you need a long-term production solution, look at the TE Greenpar family for a current boot that matches your connector type and cable OD.
