4-Pin Shrouded Header at 3.50 mm Pitch – What It Carries
The 0395011004: This is a 4-position, single-level terminal block header from the Molex Eurostyle ESE 39501 series.
Through-Hole Vertical Mount – Board Layout Note
The header mounts vertically through the PCB with a contact tail length of 0.140" (3.56 mm) and an insulation height of 0.360" (9.14 mm). The vertical orientation keeps the wire entry perpendicular to the board, which simplifies routing in a DIN-rail enclosure where the PCB sits parallel to the rail. Tin-plated brass contacts are terminated by soldering into plated through-holes — no crimp tooling needed on the header side.
RoHS3 compliant per the manufacturer's declaration. No official pin-compatible alternative is recorded within the Eurostyle ESE 39501 series at this position count and pitch — the 4-position, 3.50 mm configuration is specific to this order code.
