The TE Connectivity Buchanan 284391-6 is a 6-position, single-level PCB terminal block on a 0.138" (3.50 mm) pitch, designed for wire-to-board termination via a screw-rising cage clamp. The green polyamide (PA66) housing is rated for 12 A at 300 V, accepting wire from 14 to 30 AWG. This is the 6-position member of the Buchanan series, a long-running family of fixed-mount terminal blocks used in industrial control panels, power supplies, and building automation where field wiring changes are routine.
Wiring and Termination — Screw-Clamp Field Service
Wire termination uses a rising cage clamp actuated by an M3 screw. The clamp material is brass with nickel plating; the screw is also brass-nickel. The specified torque is 0.25 Nm (2.2 Lb-In) — overtightening can strip the PA66 threads or deform the clamp.
No end-of-life notice or successor has been issued.
Board Layout and Ganging
The side interlocking feature allows multiple 284391-6 blocks to be mechanically linked side-by-side, creating a multi-position assembly without gaps. This is useful when the circuit count exceeds 6 and a single wider block is not available or preferred. The through-hole mounting provides mechanical retention during soldering and vibration.
