FANUC A20B-3300-0090 Monochrome LCD Graphics Driver PCB

Main Description

The FANUC A20B-3300-0090 is best described as a monochrome LCD graphics / video display card for FANUC i Series controls.

Product listings tie this model to 9 inch or 9.5 inch monochrome display use and repeatedly associate it with 16i, 18i, 20i, 21i, and Powermate i control platforms. Several sources also describe it as a plug-in graphics or video controller PCB that installs on the main CPU side or rear of the LCD/MDI assembly.

For industrial buyers, this is a display-side board rather than a general control PCB.

That matters because graphics cards are normally sourced by exact part number, screen type, and control family context. 

Product Data

Where This Board Fits

The A20B-3300-0090 is most suitable for LCD graphics-board replacement in FANUC i Series controls where the installed display-side board needs to be matched by exact number. Because the model is consistently described as a graphics driver PCB or video display card for monochrome LCDs, it is particularly useful in repair workflows where the issue is isolated to display output, video drive, or LCD-side graphics processing rather than to the entire control system.

It is also a practical fit for repair-center diagnostics, LCD/MDI board evaluation, and legacy i Series spare-parts planning.

FAQ

1. What is the clearest product name for A20B-3300-0090?
The clearest name is monochrome LCD graphics driver PCB. That wording combines the most stable identifiers attached to the part number: graphics driver, video display card, and 9–9.5 inch mono LCD use.

It is more useful than a generic PCB label because it reflects how buyers actually identify this board in service.

2. Why do 9 inch and 9.5 inch both appear in listings?
Different sellers describe the display size slightly differently, but they consistently place the board in the same monochrome LCD graphics-driver role for i Series controls.

For a product page, it is safest to preserve that shared display-side identity without forcing the page into a stricter size claim than the listings consistently support.

3. Why are 16i, 18i, 20i, 21i, and Powermate i worth mentioning?
Because these control-family references help buyers validate the board against the installed hardware.

In repair work, graphics boards are often compared using both part number and control family, especially when the technician is working from an LCD/MDI assembly or a master-board-side plug-in card.

4. Is this better listed as a graphics card or as a PCB?
Both are acceptable, but graphics card, video display card, or graphics driver PCB should lead. “PCB” is useful as the catalog class, while the graphics/display wording is the part that gives the listing meaningful technical value.
