Controller Port Repair and Clock Battery Kit for Sega Dreamcast

Service common Sega Dreamcast controller-port and clock-battery faults with a component kit that also supports an LED color upgrade.

Product Details

• Resettable 72V 400mA fuse for controller-port power faults
• 47uF 10V electrolytic capacitor
• 13-ohm 1/2-watt resistor with 1% tolerance
• BAT85 30V 200mA diode to block the charging path when using a CR2032
• CR2032 3V coin cell and vertical holder for easier future replacement
• 5 mm indicator LED; blue is supplied by default when no alternate color is arranged

Fitment and Compatibility

For the Sega Dreamcast controller-port PCB and clock-battery circuit using the matching original component layout. This is an electronic repair kit, not a complete controller board. Board revisions can vary; compare component values, pad locations and polarity markings before installation.

Part Number Information

No Sega OE assembly part number is stated for this aftermarket component kit. Component identifiers and ratings are listed above; the included coin cell is CR2032 3V.

Package Contents

One CR2032 battery, one vertical holder, one resettable fuse, one 47uF 10V capacitor, one 13-ohm resistor, one BAT85 diode and one 5 mm LED.

Installation Notes

Advanced soldering is required. Polarity matters for the battery, diode, capacitor and LED. The diode must block the Dreamcast charging path because a standard CR2032 is non-rechargeable. Incorrect installation can damage the console; professional electronics repair is recommended.
