It carries a 0.165" (4.20mm) mating pitch — the same on both rows — and is rated 13A per circuit at 600V.
The 13A per-circuit rating suits power rails. The tin-on-tin contact finish keeps cost down and works for moderate mating cycles.
The 2825261-8 is the 8-position, dual-row, straight through-hole member of the VAL-U-LOK series. Compared to the 20-position 4-1775099-7 (same pitch, same tin finish, same 600V rating but 9A per circuit), the 2825261-8 carries a higher current per contact — 13A vs 9A — so it's the better pick when the circuit count is lower but the load per line is higher. Both are active, both use the same locking ramp and board lock features.
