Barrier Block, 2 Circuits, 20 A — 0.325" Pitch
The TE Connectivity Buchanan 4DB-P107-02 is a 2-circuit barrier terminal block with a 0.325" (8.26 mm) pitch, rated 20 A per circuit at 150 V. It accepts wire from 12 AWG down to 22 AWG, terminated via screws on top and PC pins on the bottom for through-hole soldering to the board.
20 A Rating and Wire Acceptance
The 20 A per-circuit current rating is the defining spec for this barrier block — it is a power interconnect, not a signal terminal. The 12-22 AWG wire range covers common power and control conductors; the dual-wall barrier design (2 Wall) provides physical isolation between adjacent terminals to prevent accidental shorting during wiring.
The 4DB-P107-02 is an active Buchanan series part with no obsolescence notice on record.
