Automotive Connector Terminal – 1928498807 / DJ6251-4.8C, 4.8mm Female Crimp Contact

OEM-specification 4.8mm female crimp terminals for Volkswagen Group (VW, Audi, Skoda, SEAT) and Bosch wiring harnesses. Part number 1928498807 is the Bosch/TE Connectivity catalog number; DJ6251-4.8C is the Chinese standard equivalent. The 4.8mm pitch is larger than the 2.8mm series (1928498806) and is used for higher-current circuits — fuse box connections, relay sockets, main power distribution, and high-current actuator connections throughout European vehicle electrical systems.

Key Specifications

2.8mm vs 4.8mm vs 6.3mm Terminal Series

• 2.8mm (1928498806): For signal and low-current circuits (up to 10A). Sensors, lighting, and control circuits.
• 4.8mm (1928498807, this product): For medium-current circuits (15–20A). Fuse box connections, relay sockets, motor circuits, and heated seat connections.
• 6.3mm: For high-current circuits (25–30A+). Main power distribution, starter motor connections, and high-current accessories.
• Selection rule: Match the terminal pitch to the existing connector housing. Do not substitute a different pitch — the terminal will not fit correctly in the housing cavity.

Frequently Asked Questions

What are the most common applications for 4.8mm terminals in VW vehicles?

4.8mm terminals are used throughout VW Group vehicles for medium-current circuits: (1) Fuse box connections — the fuse box uses 4.8mm terminals for circuits up to 20A. (2) Relay sockets — relay coil and contact connections in the fuse/relay box. (3) Heated seats — seat heater element connections. (4) Window regulators — motor power connections. (5) Cooling fan — fan motor power connections. These are the most common locations for 4.8mm terminal damage from overheating (sustained overcurrent) and corrosion.

What crimp tool is required for 1928498807 terminals?

Bosch specifies the 1 987 010 502 crimp tool (or equivalent) for 4.8mm terminals. The correct die must match the 4.8mm terminal’s wire barrel geometry. Using the wrong crimp tool produces an incomplete crimp. For professional automotive electrical repair, use a ratchet crimp tool with the correct die for 4.8mm contacts.

How do I repair a burnt fuse box terminal?

Burnt fuse box terminals are a common failure in VW Group vehicles, caused by sustained overcurrent through an undersized fuse or a high-resistance connection. Repair procedure: (1) identify and fix the root cause (replace the fuse with the correct rating, repair the circuit fault); (2) extract the burnt terminal from the fuse box housing using a terminal extraction tool; (3) cut the wire behind the burnt terminal; (4) crimp a new 1928498807 terminal onto the wire; (5) insert the new terminal into the fuse box housing. If the housing cavity is melted or deformed, replace the fuse box housing.

Typical Applications

• VW Group vehicles: Fuse box, relay socket, and medium-current circuit terminal replacement
• Bosch components: 4.8mm terminal replacement in Bosch relay and fuse assemblies
• European OEM repair: Medium-current circuit terminal replacement in European vehicles
• Automotive workshops: Workshop stock for VW/Audi fuse box terminal repairs
