Active Production, ROHS3, UL94 V-0 Housing
The 2029104-3: It is ROHS3 compliant, meeting current regulatory requirements for most markets.
Selection Contrast: 2.00 mm vs 3.00 mm Pitch
Compared to the 1-292164-1 (CT series, 2.00 mm pitch, 11 positions, through-hole), the 2029104-3 uses a wider 3.00 mm pitch that opens up board routing and supports higher current per contact before derating. The 2029104-3 is SMD right-angle, while the 1-292164-1 is through-hole right-angle — the SMD version eliminates the drilling step and suits double-sided boards. The 1-1871673-2 (2.50 mm pitch, 4 positions, through-hole, board lock) is a dual-row part with a different footprint and mounting style. The 2029104-3 is a single-row, 3-position part — the choice between them depends on the circuit count and board layout requirements.
The solder retention feature adds a mechanical anchor to the board.
