| Model Number | A20B-8200-0392 |
The A20B-8200-0392 is a FANUC main PCB in the A20B-8200 family. Public listings identify it as a ZERO i-C MAIN PCB, and another public source describes it as a FANUC Series 0i-C Mainboard.
Additional public listings place it in the main-board category and note that it is discontinued by manufacturer, which reinforces its role as an installed-base replacement board rather than a current general-purpose PCB.
As a main PCB, this board belongs at the center of the CNC control structure.
In board-level service work, that means exact model continuity matters because the main board defines the original control platform, board-family position, and internal hardware layout of the machine.

| Public Market Classification | Board / Main board |
This board is suited to installed FANUC 0i-C / ZERO i-C CNC systems where the machine already uses the A20B-8200-0392 main-board structure.
It is especially relevant in controller repair, board refurbishment, and lifecycle support where the original control platform needs to remain aligned with the same main-board family.
Before ordering, confirm the installed part number, verify that the machine uses a ZERO i-C / 0i-C control platform, and make sure the original main board is A20B-8200-0392.
Since public listings also note discontinuation, exact model confirmation is especially important in spare-parts planning.
Q1: What kind of board is A20B-8200-0392?
It is a FANUC main PCB. Public listings identify it specifically as a ZERO i-C MAIN PCB, and other sources describe it as a FANUC Series 0i-C Mainboard, which places it at the core of the installed CNC hardware.
Q2: Why is the ZERO i-C / 0i-C description important?
Because that description identifies the board’s installed control family. Main boards are selected by exact control platform, and the repeated ZERO i-C / 0i-C wording is one of the clearest compatibility markers for this model.
Q3: Is this a core control board or a peripheral board?
It is a core control board. Public listings place it in the main board / mainboard category, which means it belongs to the central hardware structure of the CNC system rather than to a peripheral board position.
Q4: Is there any public lifecycle note for this model?
Yes. One public industrial listing marks A20B-8200-0392 as discontinued by manufacturer, which makes it especially relevant in installed-base service and replacement work.
Q5: What should be checked before ordering?
Check the installed part number, confirm the control platform is ZERO i-C / 0i-C, and verify that the original main board is A20B-8200-0392. Those are the main compatibility points supported by the available public references for this model.
