Q 1. What does the WAI 12136N replace — which original Mitsubishi part numbers does it cross to?

A. The WAI 12136N is a direct replacement for Mitsubishi original-equipment alternators, crossing to Mitsubishi A007T03371, Mitsubishi A007T03371A, Mitsubishi A7T03371, and Mitsubishi A7T03371A. A total of 14 OE cross-references are verified for this part, including numbers from Nissan, Denso, Delco Remy, Sando, AD Kuhner, and DRI. Use our cross-referenced catalogue or ask Simon to confirm fit by OE number.

Q 2. Which Nissan machines is this alternator compatible with?

A. The 12136N fits 14 Nissan applications and 8 TCM Equipment applications — 22 in total. Confirmed Nissan models include the CPJ, KAH, KAP, KCEH, KCH01, KCH02, KCPH, and KCUGH, covering build years from 1993 to 2007. Use the selection widget to match your exact model and build year, or search by OE number. Every fitment listed is backed by our Fit Guarantee.

Q 3. Does this replace Nissan part numbers 23100-50K10 or 23100-87V10?

A. Yes. The WAI 12136N cross-references directly to Nissan 23100-50K10, Nissan 23100-87V10, Nissan 2310050K10, and Nissan 2310087V10 — all four Nissan OE numbers verified for this part. If you are matching by a Nissan part number, you can also search our catalogue by that reference to confirm fitment, or ask Simon.

Q 4. What are the key specs — voltage, output, and rotation direction?

A. The 12136N is a 12-volt alternator with a 35-amp output. It runs clockwise rotation and is fitted with a groove pulley. The IR/IF (internal regulator / internal fan) design means the regulator is housed inside the alternator body, so no separate external regulator is required. The unit is supplied brand new.

Q 5. Does this cross to the Denso 2109010 or Delco Remy DRA3888 as well?

A. Yes — both are verified cross-references for this part. The Denso USA reference is 2109010 and the Delco Remy reference is DRA3888. Sando references 20351860 and 20351861 are also listed. In total there are 14 confirmed OE references across Mitsubishi, Nissan, Denso, Delco Remy, Sando, AD Kuhner, and DRI.

Q 6. What does IR/IF mean on an alternator, and does this unit need an external regulator?

A. IR/IF stands for Internal Regulator / Internal Fan. Both the voltage regulator and the cooling fan are housed within the alternator body itself. This means no external regulator is needed, and installation is straightforward — the unit connects and operates as a self-contained assembly in place of the original.

Q 7. Is this part covered by your Fit Guarantee?

A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.

Q 8. How do I confirm this alternator 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.
