The 8-position dual-row layout here gives you more room per contact for routing traces between pads — useful when the board carries higher-voltage signals. Compared to the 4.20mm pitch ATX header 4-1775099-7 (20 positions, 9A), this Grace Inertia part runs at a tighter pitch and lower current density, but the latch holder and shrouding are similar. The key difference is position count and current capacity — pick the ATX if you need 9A per circuit and 20 positions.","metaTitle":"4-1971906-4 TE Connectivity Header 8 Pos 3.3mm Pitch","metaDescription":"4-1971906-4 TE Connectivity Grace Inertia header, 8 positions, 3.30mm pitch, 250VAC, UL94 V-0.
