“220V ONLY – NOT FOR US/CANADA”
The Heart Transplant for Your DCF887
When the “magic blue smoke” escapes from your impact driver, or the trigger becomes completely unresponsive, your tool isn’t necessarily dead—it just needs a heart transplant. The N880474 Motor and Switch Assembly is the central nervous system of your tool. Instead of diagnosing micro-soldering faults on a burnt control board, this complete aftermarket drop-in assembly allows you to replace the entire electronic drivetrain in under 20 minutes.
What’s Included in the Harness?
To ensure a seamless repair process, this N880474 aftermarket unit comes fully pre-wired from our factory. It includes:
- High-efficiency Brushless Stator (Motor Body)
- Variable Speed Actuator (Trigger Switch)
- Encapsulated Electronic Control Module (Sealed against jobsite dust/moisture)
- Base Battery Terminal Receptacle
- LED Worklight Wire Harness
Tech Q&A: Field Diagnostics
Q: Does this assembly include the magnetic spinning rotor?
A: No. This is the Stator, Switch, and Control Board assembly. You will need to slide your existing, functional magnetic rotor (armature) into the center of this new stator during reassembly.
Q: How do I know if I need to replace the N880474 assembly?
A: The most common symptoms of a failed N880474 unit include: a heavy acrid burning smell, the tool stuttering or cutting out under load, the LED light turning on but the motor refusing to spin, or a completely dead trigger response despite a fully charged battery.
Q: Is this specifically the 220V version?
A: Yes, this specific aftermarket iteration is engineered to match the electrical specifications of the 220V regional market variants of the DCF887. Please verify your tool’s regional type before ordering.

Yes. This premium aftermarket variable speed switch assembly is engineered to be fully compatible with popular 20V MAX brushless impact drivers that require part number N880474, specifically the highly popular DCF887 (Types 1, 2, and 3) models. It is designed to restore crisp trigger response and precise RPM control.
Brushless tool electronics fail differently than older brushed motors. The most common symptom of a bad N880474 switch is a “half-dead” tool: you pull the trigger, the LED work light turns on, but the motor refuses to spin. Other telltale signs include the tool only working in one direction (forward but not reverse), a mushy trigger feel, or completely losing variable speed control (it only runs at full speed).
Yes. The wiring routing inside a compact brushless impact driver is extremely tight. Crucial Pro Tip: Take multiple photos of your tool’s open housing before removing the old switch. When installing this new N880474 assembly, ensure every wire is pressed deeply into its designated plastic channel. If a wire sits even slightly too high, the clamshell handle will pinch and sever it when you tighten the screws, immediately destroying the new switch.
