The Molex Eurostyle ESE 39543 395430008 is an 8-position, single-level PCB terminal block on a 0.197" (5.00mm) pitch. It's a side-entry design — wires enter parallel to the board — terminated with a screw and leaf spring that cinches down through a wire guard. That guard keeps stranded conductors from fanning out under the screw head, which is a practical touch for 14-24 AWG field wiring in control panels or lighting fixtures. The through-hole mounting and Black PA66 housing are standard for this duty.
The 395443008 carries a higher current rating (15 A vs 10 A) and accepts a wider wire range (12-30 AWG vs 14-24 AWG). For a panel originally built around the 395443008, the 395430008 would work only if the circuit load stays under 10 A and the wire gauge is within 14-24 AWG — and the PCB pitch matches. Sourcing both as active parts is straightforward, but choose by the board layout and the current draw, not by the position count alone.
