The tin-plated phosphor bronze construction keeps per-unit cost low for high-volume harness builds, but the tin finish limits mating cycle life compared to gold-plated alternatives — expect reliable performance through a few dozen mate/unmate cycles in a field-service scenario, not thousands. The stamped forming process means the contact beam geometry is consistent reel-to-reel, giving a repeatable insertion force into the housing cavity. ## Wire Gauge Fit and Crimp Termination The 170366-4 accepts 18-22 AWG stranded wire — the crimp barrel is sized for that range, and using wire outside it risks poor pull-out force or barrel damage. Crimp termination is standard; the stamped contact feeds through a reel-fed applicator or hand-crimp tool. The socket mates with the matching Mini-Universal MATE-N-LOK pin contact (the male half) inside the housing, and you should hear it click when the terminal latch engages the housing cavity — if it backs out under a light tug, the terminal isn't fully seated. ## Active Production and Sourcing The 170366-4 carries an active lifecycle status — no obsolescence notice, no last-time-buy deadline. It is sourced to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time. There is no official successor or direct cross-reference on record from TE, so if your BOM specifies this exact base product number 170366, the 170366-4 is the socket variant to order.","metaTitle":"TE 170366-4 Mini-Universal MATE-N-LOK Socket, 18-22 AWG","metaDescription":"TE Connectivity 170366-4 stamped socket contact for Mini-Universal MATE-N-LOK series.
