Sumitomo 8240-4438 250 Type (6.0mm) 0.3mm² Female Brass Terminal

Sumitomo 8240-4438 250 Type (6.0mm) 0.3mm² Female Brass Terminal

The Component: Genuine Sumitomo high-performance female receptacle crimp contact terminal. 250 Type (6.0mm) Interconnect taxonomy / Female receptacle terminal contact / Standard Unplated Brass Construction / High-Conductivity General Purpose Leaf / Open-Barrel Wire Contact / Component Variant Alias: 8240-4438 / Global Order Reference: 82404438 / Sumitomo Component Class: 250-F Female Terminal Contact.

Applications & Fitment: Engineered as a premium, high-conductivity original equipment (OE) specification crimp terminal contact block designed explicitly for automotive power distribution layouts, ground networks, high-load lighting infrastructure, and general-purpose vehicle electrical infrastructure. This 6.0mm (.250 inch) nominal blade width female socket contact is an absolute wire harness remanufacturing, custom loom assembly, and localized field repair staple across leading international vehicle platforms—most extensively integrated within Toyota, Lexus, Honda, Nissan, Mitsubishi, and Subaru factory automotive automotive electrical systems. It is standardly deployed across high-current terminal pathways, serving as the main internal conducting node for ignition switch routes, relay block panels, blower motor fan links, dashboard distribution grids, and standard unsealed multi-pole interconnect housing configurations.

It features a high-elasticity structural copper alloy floor leaf assembly that exerts continuous, stable mechanical contact friction over the mating male pin terminal blade, establishing a secure, low-tolerance connection path resilient to extreme structural vibration and localized cabin thermal fluctuations. Engineered to conform to rigid tier-1 automotive manufacturing and contact resistance standards, its open-barrel crimp tail features specialized conductor and insulation ears designed to wrap tightly around low-cross-section core strands and strain-relief wire lines, establishing an air-tight gas crimp matrix that totally eliminates terminal push-back and preserves power delivery purity across continuous service lifetimes. Highly critical service item for auto-electrical workshops, marine electronic installers, fleet maintenance hubs, and aftermarket harness builders executing terminal overhauls inside brittle factory block housings.

Technical Attributes:

- Manufacturer Part Number: 8240-4438 / 82404438 (Brand: Sumitomo / Japan Genuine Component Class)

- Product Series Taxonomy: 250 Type (6.0mm) Series Automotive Interconnect Family

- Component Type: Open-Barrel Female Receptacle Socket Crimp Terminal Contact

- Mating Terminal Dimension: Designed to receive 6.0mm (.250 inch) nominal tab width male blade pins

- Base Metallurgical Compound: Premium plain Brass base metal providing high mechanical structural stiffness and superior electrical conductance

- Surface Finish Treatment: Unplated Raw Brass optimal for high-conductivity terminal pathways inside unsealed environments

- Wire Range Capacity Accommodation: Form-fitted specifically for small-diameter automotive low-voltage cross-sections at 0.3mm² nominal core width (approx. 22 AWG down to micro signal runs)

- Crimp Configuration Profile: Open-barrel dual-zone tail structure requiring independent core conductor crimping and insulation strain-relief wrapping

- Housing Integration Compatibility: Precision optimized to click directly into the primary internal retention paths of standard Sumitomo 250 type unsealed automotive housing matrix cavities

- Circuit Rating Threshold: Form-fitted for dedicated low-voltage signal distribution paths and power delivery loops; capacity limited dynamically based on the thin-gauge 0.3mm² wire cross-section and environmental limits

- Operational Thermal Window: Severe-duty cabin panel, chassis loom run, and unsealed boot route layout certified to maintain material spring elasticity and low circuit resistance across standard automotive operating ranges

- Assembly Recommendation: Requires professional open-barrel automotive crimp tools featuring F-crimp profile jaws (such as Engineering PA-21 or specialized Sumitomo factory applicator mini-dies) to guarantee correct wire compaction and complete mechanical strain security

- Commercial Access: Available as loose individual workshop pieces, convenient trade repair refill packs, bulk loose trade boxes, or continuous reel runs for automated wire processing machinery.
