DJ7013B-6.3-21 Automotive Yellow Rectangular Connector — 6.3mm 1-Pin Jacketed Wiring Plug
The DJ7013B-6.3-21 is a 1-pin yellow rectangular automotive connector in the 6.3mm series, designed for jacketed (sheathed) wiring harness applications. The distinctive yellow housing provides visual identification in multi-connector harness assemblies, while the 6.3mm terminal pitch delivers robust current-carrying capacity for higher-load circuits such as ignition coils, fuel injectors, and high-current sensors. Manufactured to OEM dimensions for direct replacement compatibility.

6.3mm Terminal Series — Why It’s Used for High-Current Circuits
- 15A current rating — the 6.3mm terminal pitch handles significantly higher current than 2.8mm or 1.5mm series, making it standard for ignition coils, fuel injectors, and blower motors
- Yellow housing for visual ID — color-coded housings allow technicians to quickly identify connector function in dense underhood harness assemblies
- Jacketed wire design — the housing accommodates jacketed (sheathed) wire entry, providing strain relief and a cleaner installation in harness bundles
- PA66 nylon — rated for continuous underhood temperatures; resistant to engine oil, coolant, and common automotive fluids
- OEM dimensions — direct replacement for original equipment; no modification required

Frequently Asked Questions
Q: What is the current rating of the 6.3mm terminal?
The 6.3mm series terminal is rated for up to 15A continuous current with appropriate wire gauge (1.5–2.5mm² / 16–14 AWG). This makes it suitable for ignition coils, fuel injectors, and other moderate-to-high current automotive circuits.
Q: What does the “-21” suffix mean in DJ7013B-6.3-21?
In the DJ series naming convention: the first number after the dash indicates the terminal pitch (6.3mm), and the last two digits indicate gender and sealing — -11 = male unsealed, -21 = female unsealed, -11/21 = matched male/female pair. The “B” suffix indicates a specific housing variant (jacketed wire entry in this case).
Q: Do I need a special crimping tool?
Yes — use a ratchet-type automotive crimping tool with a jaw sized for 6.3mm terminals. A proper crimp is gas-tight and withstands a minimum 30N pull-out force. Pliers or generic crimpers will produce an unreliable connection that may fail under vibration or thermal cycling.
