What the 395433003 is
The Molex 395433003 is the 3-position member of the Eurostyle ESE 39543 series — a side-entry through-hole terminal block with rising cage clamp termination. The black polyamide housing carries three circuits at 0.197 in (5.00 mm) pitch, rated 15 A per contact at 300 V, accepting 14-22 AWG wire.
What the ratings mean for the fit
The -40°C to 105°C operating range covers the typical industrial enclosure ambient — the polyamide housing holds its geometry through thermal cycling better than some of the PBT-bodied siblings in adjacent series. Horizontal PCB mount means this block occupies a defined z-height envelope at the board edge; confirm your board stack-up clears the side-entry wire entry angle before committing the BOM line.
Where these blocks are used
Eurostyle ESE 39543 terminal blocks are a common PCB power entry point in industrial automation cabinets, motor drives, and HVAC control panels — anywhere a discrete wire harness must land on a PCB under field-service access constraints. The side-entry orientation keeps wire routing close to the board plane, which matters when the enclosure depth is constrained. The 3-position count suits single-phase power or a small control bus.
Sourcing and compliance
The 395433003 is Active and ROHS3 Compliant. No official successor or cross-reference appears in the on-record lifecycle data. Confirm the 3-position count and the 5.00 mm pitch against the existing BOM before issuing an RFQ — the mating half must be the matching 3-position Eurostyle ESE plug or the corresponding front-entry variant with the same pitch and current rating.
