The Molex 2002771203 is a 3-circuit plug from the Nano-Fit 200277 series, a wire-to-board interconnect family built for compact power delivery in space-constrained enclosures. Glow wire compliance (IEC 60335-1) means this plug can be specified in household appliances and lighting fixtures where the standard requires the connector to self-extinguish under fault conditions. The panel mount, snap-in feature lets you pre-install the plug into a panel cutout before wiring, which speeds harness assembly.
This plug ships as a housing only — the male pin crimp terminals are not included. The note on the listing is unambiguous: Contacts Not Included. Ordering the housing without terminals is the most common BOM miss on this part.
Mating Connector and Compatibility
The 2002771203 plug mates with the Nano-Fit 200277 receptacle (female housing) of the same circuit count and pitch — a 3-circuit, 2.50 mm pitch receptacle. The plug is compatible with the full Nano-Fit 200277 terminal system — use the same wire gauge range as the receptacle side for a consistent crimp.
For a 3-circuit, 2.50 mm pitch plug with glow wire compliance, this part consolidates one SKU in the Nano-Fit range — no single-vendor lock beyond the series itself.
