The TE Connectivity 172781-3 is a wire-to-board crimp terminal from the Mini Amp-In series. It is a loose-piece contact designed for crimp termination into a mating housing, typically used in low-to-moderate current signal and power applications within consumer appliances, automotive interior harnesses, and industrial control panels. The terminal accepts 26-30 AWG wire and is rated for a hole diameter of 0.047" ~ 0.063" (1.19mm ~ 1.60mm), which defines the panel or housing mounting aperture it fits through. The contact is made of brass with a tin finish — a standard combination for cost-sensitive, moderate-cycle environments where corrosion resistance is adequate for indoor use.
Physical Dimensions and Termination Fit
The terminal has an overall length of 0.335" (8.50mm) and accepts an insulation diameter of 0.043" ~ 0.055" (1.10mm ~ 1.40mm). The hole diameter range of 0.047" ~ 0.063" (1.19mm ~ 1.60mm) is the clearance the terminal needs through the panel or housing cavity — not the crimp barrel ID.
