Sumitomo 8100-3803 RS Series 2.3mm Male Terminal

The Component: Genuine Sumitomo 8100-3803 automotive sealed male tab blade crimp terminal contact. RS Series (Standard Type 1) 2.3mm (090) nominal sizing classification / Precision-formed high-conductivity brass / Tin-plated finish / Loose piece strip tracking / Component Alias Code: 81003803 / Global Order Reference: 8100-3803.

Applications & Fitment: Engineered as a high-reliability, factory original equipment (OE) mid-sized terminal link for robust automotive wiring harnesses. This 090-size (2.3mm) male tab terminal is a definitive factory standard across major Japanese passenger car architectures—including comprehensive deployment across Nissan, Toyota, and Honda powertrain and lighting networks. It serves as the primary replacement crimp pin inside high-vibration engine bay junctions, specifically matching the Nissan 8-way front headlight plug assemblies (working hand-in-hand with the 6918-1780 green front lock retainer plate).

Sized perfectly to process low-to-medium current telemetry paths safely without introducing localized voltage dropouts, it protects critical circuit paths from intermittent signal failures. Highly vulnerable to blade twisting, core wing split fractures, or locking latch deformation if field technicians attempt to crimp cables using generic un-profiled hand tools rather than calibrated automotive micro-die sets, or if forced blindly during housing extractions.
