6.3 mm (0.250") Insulated Female Spade Crimp Terminals — Faston-Style, PVC, Brass/Copper — Red / Blue / Yellow — 50 Pack
Insulated female spade crimp terminals (Faston-style) for 6.3 mm (0.250") quick-disconnect tabs. The terminal body is precision-formed from brass with a copper contact interface for low contact resistance and stable conductivity. A PVC insulator sleeve provides strain relief and electrical insulation. Color coding (red/blue/yellow) aligns with standard conductor ranges for automotive, appliance, and industrial wiring.
Functional Characteristics
- Interface: Female receptacle for standard 6.3 mm (0.250") male quick-connect tabs (typ. 0.8 mm thickness).
- Electrical path: Brass body with copper contact material to reduce milli-ohm contact losses.
- Insulation: PVC sleeve for dielectric isolation and crimp-area strain relief.
- Crimp type: Closed-barrel style for use with ratcheting/hex/dieless crimp tools matched to conductor size.
- Retention: Spring geometry provides positive engagement and withdrawal force on mating tab.
- Compliance: No high-concern chemicals (RoHS-oriented bill of materials).

Selection Matrix (Color → Conductor Range)
Choose the insulator color that matches your wire gauge for optimal crimp quality and pull-out strength.
| Color (Model) | Conductor Range (mm²) | Conductor Range (AWG) | Use Case Examples |
|---|---|---|---|
| Red | 0.5–1.5 mm² | 22–16 AWG | Low-current signals, light automotive circuits, control wiring |
| Blue | 1.5–2.5 mm² | 16–14 AWG | General automotive, appliance branch circuits, industrial I/O |
| Yellow | 4.0–6.0 mm² | 12–10 AWG | Higher-current feeders, power distribution drops, marine |
Note: Conductor ranges above are typical for insulated spade terminals; verify against your site specification and crimp-tool die set.
Installation & Crimping Guidance
- Strip conductor to the tool/die’s specified length; avoid nicking strands.
- Insert fully into barrel; position the die on the barrel (not the insulation) unless using an insulation-support die.
- Crimp with a calibrated ratcheting tool matched to the chosen color/gauge.
- Perform a gentle pull test to verify mechanical retention; inspect for full barrel compression.
- Mate with a clean, burr-free 6.3 mm (0.250") tab; ensure full engagement for contact stability.
Applications
- Automotive harnesses, motorcycles, marine, RV
- Home appliance service (HVAC, refrigerators, ovens, washers/dryers)
- Industrial control panels and machinery wiring
- Audio speakers, power supplies, LED drivers, accessories
Dimensional Notes
Please allow 1–2 mm measurement variation due to manual measurement and manufacturing tolerances.
