50 Positions at 1.27mm Pitch — Signal-Density Fit
The 20021521-00050T1LF: This Minitek127 header packs 50 circuits into a dual-row, 1.27mm pitch footprint — that's 0.050" centerline, which means the board-side routing density is about double what a 2.54mm pitch would give you on the same edge length.
Surface Mount Assembly and Temperature Range
The SMT termination suits automated pick-and-place lines — the header ships in tube packaging, so plan for tube-fed feeders or a tube-to-tape conversion if your line runs tape-only. Insulation height is 0.220" (5.60mm) above the board, which gives clearance for routing under the header on the top layer if the board stack-up allows.
Position Count Comparison: 50 vs 20 vs 10
The same Minitek127 series offers 20-position (20021521-00020T1LF) and 10-position (20021521-00010T1LF) variants, all sharing the same 1.27mm pitch, dual-row layout, gold flash contacts, and SMT termination.
