Crimp termination and wire gauge
The 647466-2 is a 16 AWG crimp socket from the TE Connectivity SL-156 series, terminated by crimp — no soldering required for the wire-to-contact joint.
Positioning within the SL-156 series
Wire gauge is the primary differentiator: the 647466-2 accepts only 16 AWG, while the 770476-2 and 350980-3 accept 18-24 AWG — match the contact to the cable size before crimping.
