What this terminal block is
The Molex 398800402 is a 2-position, single-level Eurostyle 39880 rising-cage terminal block with a 0.200 in (5.08 mm) pitch — the standard grid for compact wire-to-board interconnects in control panels and industrial automation DIN-rail or chassis-mounted harness nodes. Rated 17.5 A per circuit at 300 V, it accepts 12-30 AWG conductors through a screw-type rising cage clamp that grips the full conductor cross-section without cold flow, making it a practical choice for field termination and panel build where torque specification matters.
Contact plating and housing ratings
Tin plating on the contact surface is the right grade for production wiring runs where high mating-cycle life is not the primary driver — the 12-30 AWG range covers signal and power branch conductors in the same block. The PA/Nylon housing holds an operating envelope of -40 °C to 105 °C, suitable for most industrial enclosures without active cooling, and the nickel-plated clamp and screw body resist the corrosion that plain brass or bare steel picks up in humid harness environments.
Where this class of connector is used
Eurostyle rising-cage terminal blocks are a fixture in industrial automation panel wiring and DIN-rail instrumentation: they land on PCB edge connectors or pass-throughs in PLC I/O modules, motor drives, and power supplies, where the wire-entry side faces the field termination and the PCB tails face the board. The 2-position count suits single-circuit branch takeoffs or signal-pair pass-throughs rather than multi-wire bus bars.
Lifecycle and sourcing
The 398800402 carries an Active lifecycle status and ROHS3 Compliant marking. It ships in bulk packaging. No official successor order code appears on record for this part, so for BOM commitment the 398800402 itself is the sourced line. Confirm the 35-degree mounting orientation and the 2-position count match your board layout before issuing an RFQ.
