Q 1. Which Mitsubishi part numbers does the WAI 12563N replace?

A. The WAI 12563N replaces five Mitsubishi original-equipment references: A003TN5379, A3TN5379, ME049321, MEO49321, and Mitsubishi Motors MEO49321. If your existing alternator carries any of these numbers, the 12563N is the direct replacement. To confirm fit for your specific machine or application, search our cross-referenced catalogue by OEM number or ask Simon.

Q 2. What does IR/IF mean on this alternator, and does it need an external regulator?

A. IR/IF stands for Internal Regulator, Internal Fan. Both the voltage regulator and the cooling fan are contained within the alternator body itself, so no separate external regulator is required. This makes the 12563N a straightforward drop-in replacement for any Mitsubishi alternator of the same IR/IF design.

Q 3. What are the key electrical specifications — voltage, output and rotation?

A. The WAI 12563N is rated at 24 volts and 35 amps output, with clockwise (CW) rotation. It is fitted with a groove pulley. These figures must match your existing alternator and the electrical system requirements of your machine before fitting.

Q 4. Is this alternator brand new or remanufactured?

A. It is supplied brand new — not remanufactured or reconditioned — giving the full expected service life of a first-fit component.

Q 5. How do I confirm this part fits my vehicle or machine?

A. Use the selection widget to match your make, model and engine, or search our cross-referenced catalogue by OEM number, machine model or equivalent part across brands. If your vehicle is not listed, ask Simon. Every fitment shown is backed by our Fit Guarantee.

Q 6. Can I ask questions about this product before ordering?

A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
