FANUCA86L-Prefix Bought-In Unit, Variant 43 — Also Marked CP-03209, New Old Stock

Product Description

What this part is

A Fanuc-numbered unit, A86L-0050-0028, revision or variant /43, additionally marked CP-03209. New old stock, made in Japan.

What the two numbers tell you

A86L: this is a Fanuc prefix used on bought-in components and sub-assemblies — parts Fanuc buys from outside suppliers and carries under its own number so a machine builder can order them as Fanuc spares. Display units, backlights, fans, batteries and similar items sit in this prefix group. Fanuc’s own printed circuit board numbering runs on A16B, A17B and A20B instead. The strong probability is therefore that this is an outside supplier’s product wearing a Fanuc part number, and that it is a component or unit rather than a Fanuc-designed control board.

CP-03209: the original supplier’s own part number, marked on the item alongside the Fanuc number. That pairing is the normal pattern on A86L parts and it is the most promising route to identification, because a CP- prefix is a component maker’s designation rather than a Fanuc one.

Condition

New old stock, made in Japan, in open-box condition. It has not been in service, which on a component of this age is a real advantage: no thermal cycling, no coolant exposure, no repair history.

Quantity and configuration

Sold individually. One unit per purchase, supplied as the single item shown in the photographs.

Interchange guidance

Search forms include A86L-0050-0028/43, A86L-0050-0028, A86L00500028, A86L 0050 0028, A86L-0050-0028-43, CP-03209, CP03209 and CP 03209. All of them are on this page deliberately, because a buyer holding only the supplier’s CP- number needs to find the Fanuc number and the reverse is equally true.

Fanuc Corporation remains in business, and Fanuc America or the machine builder can identify an A86L number from a machine serial number — that is the authoritative route. For sourcing, the legacy CNC trade (MRO Electric, FanucWorld, Radwell) handles A86L parts.
