What the 398800309 is
The Molex 398800309 is the 9-circuit member of the Eurostyle 39880 series — a 5.08 mm (0.200 in) pitch terminal block designed for wire-to-board termination in industrial control and equipment wiring applications (K*). The housing is black polyamide (Nylon), rated for continuous operation from -40 °C to 105 °C. Contacts are tin-plated copper alloy; clamp and screw hardware are nickel-plated copper alloy. Side interlocking mouldings on the housing allow multiple blocks to be joined into a continuous row, maintaining tight header alignment in panel assemblies — the 9-position count here represents a single, mechanically independent level.
Lifecycle and sourcing
The 398800309 carries an Active product status and is ROHS3 Compliant. Quoted to order against the BOM quantity — submit an RFQ with your required volume and target date. No official successor or cross-reference is listed for this MPN; the closest pitch-aligned peer in the Eurostyle 39970 series (0399700104) is a 4-position, 10.16 mm pitch block rated 60 A — it is not a form-fit-function replacement.
