The TE Connectivity Buchanan 3-282836-5 is a 3-position, single-level PCB terminal block with a 0.197" (5.00 mm) pitch. That 5.00 mm centres spacing is the first thing to confirm against your board layout — it determines whether the hole pattern lines up. The rising cage clamp accepts 16-30 AWG wire and the M3 screw torques to 0.68 Nm (6 Lb-In) — overtighten past that and you risk stripping the brass screw.
Side-entry wiring and the interlocking trick
Wire entry is horizontal with the board — the screw terminals sit parallel to the PCB surface, so the wires run flat along the board. That orientation matters when you're routing wires inside a shallow enclosure or against a backplane. The interlocking side feature lets you snap multiple blocks together side-by-side to build a multi-pole terminal strip without a separate jumper bar. Each block has positions stamped into the housing, so the pole numbering stays clear when they're ganged up. Housing is polyamide (PA66) with a green colour — the standard industrial shade for ground or general-purpose terminal identification.
Same-series peer — 282836-3
The 282836-3 is the same 3-position, 5.00 mm pitch Buchanan block with identical ratings — 13.5 A, 300 V, same torque spec, same wire range. The only difference is the order code variant; functionally they're interchangeable. If you're sourcing a second source within the same series, the 282836-3 is the direct match.
