6-Position 5.08 mm Pitch PCB Terminal Block with Rising Cage Clamp
The TE Connectivity Buchanan 1776119-6 is a 6-position, single-level PCB terminal block on a 5.08 mm pitch, rated for 13.5 A at 300 V. It terminates wires from 16 to 30 AWG using a screw-driven rising cage clamp — the screw tightens a brass, nickel-plated clamp that pulls the wire up against the current bar, giving a gas-tight connection that holds under thermal cycling and vibration. The black polyamide housing is rated UL94 V-0 (implied by the Buchanan series standard) and mounts through-hole, with the wire entry oriented horizontally to the board.
13.5 A Continuous Rating and 300 V Isolation
That current is limited by the screw clamp contact resistance and the wire gauge — at 16 AWG the full 13.5 A is available; at 30 AWG the wire itself becomes the fuse. For a 5.08 mm pitch, the creepage between adjacent terminals is about 5 mm, which comfortably supports 300 V in pollution degree 2 environments.
Screw Termination and Torque Specification
Wire termination uses an M3 screw with a specified torque of 0.68 Nm (6 Lb-In). The rising cage clamp design — brass, nickel-plated — lifts the wire into the current bar as the screw is tightened, creating a high-pressure contact area that resists loosening from thermal expansion. The clamp accepts solid, stranded, or ferruled wire. The screw is captive in the housing, so it cannot be lost during field wiring. The specified torque is not optional: under-tightening leaves a high-resistance joint that heats under load; over-tightening strips the M3 thread in the polyamide housing.
Board Layout and Pitch Compatibility
The 5.08 mm pitch is a standard 0.200-inch spacing common to many European-style terminal blocks. The through-hole pins are on that pitch, so the PCB footprint requires a row of 6 holes spaced 5.08 mm apart, typically 1.0 to 1.3 mm diameter depending on the pin cross-section. The 5.08 mm pitch does not match 5.00 mm metric pitch boards; confirm the hole spacing before layout.
The 1776119-6 is an active, in-production part from TE Connectivity's Buchanan series.
