20-position dual-row header, 4.2mm pitch, active production
The 2-2029265-0: This TE Connectivity VAL-U-LOK header is a 20-position, dual-row, shrouded male pin header on a 4.20mm pitch, designed for board-to-wire connections. It is rated 9 A per circuit at 600 VAC, with tin-plated brass contacts throughout — mating and post.
What the 9 A and 600 VAC rating mean on the bench
The 9 A per-circuit rating is the continuous current at the connector's rated temperature rise.
The closest functional peer on record is TE 4-1775099-7, also a 20-position dual-row shrouded header at 4.20mm pitch with 9 A rating and tin-plated brass contacts. The key difference: 4-1775099-7 is rated 250 VAC (vs 600 VAC for this part) and comes in a Box package rather than Tray. Both are active, through-hole, with locking ramp and UL94 V-0. If your application needs the higher voltage headroom, this 2-2029265-0 is the correct choice.
