Board Layout Fit: 1.27mm Pitch and 30 Positions
The 20021221-00030C4LF: This Minitek127 header uses a 0.050" (1.27mm) pitch in a dual-row layout, 30 positions all loaded. The row spacing is the same 0.050" (1.27mm), so the total footprint width across both rows is roughly 1.27mm plus the body width — tight enough for dense board routing but still hand-solderable with a fine tip. Surface mount termination with pick-and-place features means it flows through reflow without extra handling.
Rated 1A per contact at the listed voltage of 125VAC. The gold mating finish at 10.0 µinch (0.25µm) over copper alloy gives a solid corrosion barrier for moderate reconnect duty — think a few hundred cycles in a clean environment. The post finish is tin, which solders well to the board pad. The UL94 V-0 housing keeps the assembly compliant inside equipment that requires a flame-rated enclosure.
