This brand new high-speed high voltage fuse is a direct replacement fuse designed specifically for the DC-DC converter system in 2012 through 2022 Tesla Model S and Model X electric vehicles. As a critical safety component in Tesla's high voltage power system, this fuse provides reliable overcurrent protection for the DC-DC converter, which is responsible for converting high voltage from the main traction battery to the 12V power that supplies your vehicle's control systems, accessories, and auxiliary battery.
Engineered to meet original equipment specifications, this fuse delivers fast response to overcurrent and short circuit conditions, preventing expensive damage to the DC-DC converter and other high voltage components while maintaining the safety and reliability of your Tesla's power system.
Original Equipment (OE) Number: 1019010-00-A
Alternative Part Number: 101901000A
✅ Direct OEM replacement for 1019010-00-A, fits 2012-2022 Tesla Model S and Model X
✅ High-speed semiconductor-grade fuse design for fast overcurrent protection
✅ Designed specifically for high voltage DC automotive systems matching Tesla engineering specifications
✅ Protects expensive DC-DC converter and on-board charging system components from overcurrent damage
✅ Low contact resistance construction for improved thermal performance and long-term reliability
✅ Brand new condition with quality tested to meet or exceed original safety standards
✅ Restores safe and reliable operation of your vehicle's 12V power supply system
In Tesla Model S and Model X vehicles, the DC-DC converter is a critical component of the power system that converts high voltage direct current from the main 400V traction battery pack to 12V DC power. This 12V power supplies all of your vehicle's accessory systems including:
Vehicle control modules and on-board computers
Exterior and interior lighting
Infotainment and display systems
HVAC and climate control systems
Power windows, seats, and door locks
Windshield wipers and auxiliary systems
Charging the 12V auxiliary battery
This fuse acts as a critical safety barrier, automatically interrupting current flow in the event of an overcurrent or short circuit in the DC-DC converter system. This fast response prevents catastrophic damage to the converter and other high voltage components, reducing fire risk and protecting your vehicle investment.
Tesla Model S (2012 through 2022)
Tesla Model X (2012 through 2022)
Important Note: Always verify your vehicle's original part number matches 1019010-00-A before purchasing. High voltage system service should only be performed by qualified professional technicians to avoid safety risks.
1 x New DC-DC Converter High Speed Fuse (OE Part # 1019010-00-A)
High voltage vehicle systems contain dangerous voltage levels that can cause severe injury or death. There are no user-serviceable parts inside high voltage components. Always disconnect high voltage systems and follow proper lockout/tagout procedures before servicing. High voltage cables are typically identifiable by their orange outer insulation. All service on high voltage systems should be performed by trained, qualified automotive technicians. In the event of a high voltage system fire, contact local emergency services immediately.
