FANUCA16B-2300-0110A16B-2300 Group Circuit Board, Revision 02A — New Old Stock, Board Only (Function Not Documented)

Product Description

What this part is

A Fanuc printed circuit board, part number A16B-2300-0110, revision /02A. It is a genuine Fanuc board number in the A16B prefix group, which Fanuc used for control boards and drive units.

What the part number does tell you

A16B: Fanuc’s PCB prefix for older-generation control boards and drive units. The others in use are A17B and A20B.

2300: the board group. Distinct from the much better documented A16B-2200 group (Series 15/16/18/21 CNC main, PMC, option and robot axis boards) and from A16B-3200 (later-generation main CPU boards).

0110: this specific board.

/02A: the revision. Worth recording: on Fanuc boards a revision change can mean a different memory capacity or feature set, not just a manufacturing tweak.

How to confirm you have the right board

Fanuc PCBs carry a twelve-digit part number beginning with A, usually printed in yellow ink on the green board. If the number visible begins A320 or A350, the A16B/A17B/A20B number is on the reverse. Boards that mount to a master PCB or backplane often do not carry the full number in yellow at all; those sit in a yellow plastic frame with a mounting screw top and bottom, and the complete twelve-digit number is on a white barcode sticker along the top edge.

Match the full number and the revision suffix. A single digit’s difference in a Fanuc part number can mean different hardware, and machine parameters are written against what was fitted.

Quantity and configuration

Board only, new old stock, sold individually. The backplane or master PCB it mounts to, the rack or card cage, daughter cards and memory modules, cabling and mating connectors, the power supply unit, and Fanuc system software, PMC ladder and machine data are each separate items.

New old stock means these boards have not been through a machine — no thermal cycling, no coolant exposure, no repair history — which on a control board of this age is a genuine advantage over a takeout.

Interchange guidance

Search forms include A16B-2300-0110, A16B23000110, A16B 2300 0110, A16B-2300-0110/02A, A16B-2300-0110-02A and A16B2300-0110. The nearest adjacent number is A16B-2300-0020 (also seen as A16B-2300-0020/03B), listed for orientation only.

Fanuc Corporation remains in business, and board-level repair and exchange for A16B boards is handled by the legacy CNC trade — MRO Electric, FanucWorld and Radwell all work on this prefix and hold documentation that is not public.
