The TE Connectivity 170338-1 is a through-board wire-to-board terminal from the Amp-In series. It accepts 18-22 AWG wire and is designed to press into a plated-through hole on the PCB, forming a solderless connection. The wire insulation diameter it accommodates ranges from 0.060" to 0.110", covering most standard automotive and appliance-grade wire jackets. This terminal is typically used in power distribution and harness-to-board interfaces where a crimped, replaceable contact is preferred over soldering the wire directly to the board.
Critical fit dimensions — get these right on the board layout
The PCB hole diameter must fall between 0.071" and 0.075" (1.80 mm to 1.91 mm). This is not a suggestion — the terminal's retention barbs rely on this interference fit. Go smaller and the terminal won't insert; go larger and it pulls out under wire strain. The overall terminal length is 0.398" (10.11 mm), which sets the minimum board thickness and clearance below the board for the crimped wire tail.
Wire preparation and crimp setup
Strip 18-22 AWG wire to the length specified in the TE application tooling drawing — the insulation diameter of 0.060" to 0.110" tells you the jacket OD the crimp barrel is sized to close around. Use the TE-certified hand tool or automatic feed crimper for the Amp-In contact family.
