What this connector is
The Molex 2119370003 is a dual-row 2-position shrouded header in the Coeur PowerWize 211937 series, rated 120 A per circuit at 300 V — a current density far above what standard shrouded headers at this form factor carry. Silver plating on both the mating face and the screw-post contact side provides the corrosion resistance and surface conductivity that sustained high-current duty demands. The 0.750-inch row spacing (19.05 mm) and the board guide feature define the footprint that governs PCB layout and panel cutout planning — this is a larger-stance connector than what the peer set carries. Surface-mount termination with screw contact engagement is the defining assembly difference against solder-only peers: the board must accommodate the SMT land pattern plus the mechanical screw engagement. The locking ramp fastening type keeps the header seated during vibration. Operating range spans -40°C to 105°C with UL94 V-0 polyester housing — suited for power-control applications in industrial and infrastructure equipment.
What makes this different from its peers
The 0.750-inch row spacing also sets it apart from the 0.118-inch pitch of the Micro-Fit+, the 0.256-inch row spacing of the CP-6.5, and the 0.250-inch pitch of the MLX header — the board footprint and panel cutout are not compatible across this set. Screw-contact termination differs from the solder-only termination of all three peers. The mating half will require a compatible screw-terminal wire entry, not a standard crimp or solder pin.
Lifecycle and sourcing
The 2119370003 carries an Active product status and is ROHS3 Compliant. No official successor or cross-reference order code is on record — confirm the mating half and BOM position count before committing.
