The TE Connectivity 925819-3 is a Mini Amp-In wire-to-board terminal — a stamped brass contact that pushes through a PCB hole and locks in place, with the wire crimped into the barrel on the opposite side. It accepts 22-26 AWG wire and fits a 0.050" (1.27mm) diameter plated-through hole. The tin-plated finish keeps contact resistance low for permanent or infrequent-disconnect applications, though it will wear faster under repeated mating cycles than a gold-plated terminal would.
Wire gauge and hole size — the two dimensions that matter
The 22-26 AWG range covers the most common signal-level wire sizes in automotive and industrial harnesses. The insulation diameter allowance of 0.040" ~ 0.060" (1.02mm ~ 1.52mm) means standard thin-wall PVC or cross-linked polyethylene insulation fits without forcing the wire into the crimp barrel at an angle. The 0.050" (1.27mm) hole diameter is the PCB drill size — the terminal's locking barb expands against the plated barrel wall once inserted, providing retention without solder.
Through-board locking termination — no solder needed
The terminal type is listed as Through Board, Locking, which means the contact has a barb or lance that catches the edge of the plated-through hole. Once pressed in, it holds position during wave soldering (if used) and under cable strain. This is a common construction for Mini Amp-In terminals — the wire is crimped to the barrel, the terminal is inserted from the component side, and the locking feature retains it through the rest of the assembly process.
