What this header carries and where it locks
The 2-2029265-4 is a TE Connectivity VAL-U-LOK dual-row header, 24 positions loaded all, on a 4.20mm pitch both between contacts and between rows.
Pitch, current, and temperature envelope
At 4.20mm pitch, this header gives you room to route thicker traces between pads compared to a 2.54mm header — useful when each circuit carries 9 A. The 0.504 inch (12.80mm) insulation height keeps the contact beam well above the board surface for wire dress clearance.

The closest functional second-source in the same VAL-U-LOK family is the 4-1775099-7 — a 20-position dual-row header with identical 4.20mm pitch, 9 A rating, tin plating, locking ramp, and UL94 V-0 housing. The difference is 24 circuits vs 20 circuits; the 2-2029265-4 gives you four more positions on the same row spacing for a denser harness.
