The TE Connectivity Buchanan 282856-5 is a 5-position, single-level PCB terminal block on a 0.197" (5.00 mm) pitch, designed for side-entry (horizontal with board) wire termination. It uses a rising cage clamp mechanism — the screw drives a clamp that lifts to capture the wire against a nickel-plated brass bus, giving a gas-tight connection without nicking strands. The green polyamide (PA66) housing is the standard color for European-style terminal blocks, and the interlocking side feature lets you gang multiple blocks together for multi-pole assemblies without a separate jumper bar.
Rated 24 A at 300 V. The wire range is 12-30 AWG. The M3 screw torque is 0.79 Nm (7.0 Lb-In).
Wire termination is screw-driven rising cage clamp: the screw turns a clamp that rises to press the wire against the current bar. The clamp and screw are brass with nickel plating, the contact bar is brass with tin plating — the tin surface mates well with both copper and tinned wire ends. Mounting is through-hole; the pins are on 5.00 mm centers and the block sits flush against the board.
The 282856-5 is the 5-position member against the 4-position 282856-4 at the same 5.00 mm pitch and 24 A/300 V rating. The decision is purely position count — if your circuit count is 4, the 282856-4 saves one terminal and a sliver of board space; if it's 5, this is the direct BOM match. No other spec differs.
