The 10127820-0622LF: This is a 6-position, dual-row header on 4.20 mm pitch — the board footprint matches the Minitek® Pwr 4.2 receptacle family.
Shrouded 4-Wall with Locking Ramp — Vibration and Mis-Mate Protection
The header is fully shrouded — four walls surround the pins, so a misaligned receptacle cannot short adjacent contacts.
Current Rating — Depends on the Wire and Terminal
The limiting factor is the crimp terminal and the wire size you choose. For a given load, select the Minitek Pwr 4.2 terminal rated for that wire gauge; the contact interface is tin-plated (80 µinch), so derate for temperature above 105°C ambient.
6 vs 8 Positions — Same Footprint, Different Circuit Count
The closest peer is the 10127820-0822LF — identical pitch, row spacing, shrouding, locking ramp, and plating. The only difference is 8 positions (2×4) vs 6 positions (2×3). If the BOM calls for 6 circuits, this is the correct part; the 8-position version is a drop-in replacement only if the board layout and receptacle have the extra two positions.
