Nissan Alternator 12V 90A OE 23100CT00B

This Nissan alternator is a new rotating electrical unit rated at 12V and 90A, supplied as part number 23100CT00B. It is listed for Nissan applications and is described as an OE alternator, so matching the part number and system specifications is the first step before ordering.

The unit is sold each, not as a kit, and carries no warranty. With a 12-volt charging system and 90-amp power rating, it is important to compare the existing alternator details in the vehicle and confirm the application carefully before purchase.

If you are replacing a failed charging unit, the key points to check are the 12V system voltage, the 90A output rating, the Nissan application, and the part number 23100CT00B. Those identifiers matter more than a broad model name when selecting an alternator for a specific vehicle.

Application and Buying Notes

Before buying, confirm the vehicle uses a 12V charging system and that the replacement alternator is specified as 90A, because output rating is a practical match point for the electrical load the vehicle was designed around. The part number 23100CT00B should be checked against the original unit or parts record wherever possible.

The fitment information supplied includes Nissan Micra references, with sample applications shown for 2007, 2008, 2009 and 2010. Those examples are useful as a guide, but they should still be verified against the vehicle identification details and the existing alternator before a purchase is finalised.

This alternator is listed as new and as an OE Nissan unit, which makes part number matching especially important when replacing an original component. Alternators can differ by voltage, amperage, connector arrangement and mounting configuration, so do not rely on the model name alone.

No warranty is stated for this item. For that reason, it is sensible to check the charging system condition, battery health and any related wiring faults before fitting a replacement alternator, so the new unit is not installed into an unresolved electrical issue.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number 23100CT00B helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Alternator 12V 90A NISSAN OE. Part number 23100CT00B should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 23100CT00B, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN MICRA, NISSAN MICRA 2007, NISSAN MICRA 2008, NISSAN MICRA 2009. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Please confirm compatibility using the part number 23100CT00B, the 12V 90A specification and the vehicle application details before ordering. If the original alternator does not match those identifiers, check the vehicle records or existing unit carefully for the correct replacement.
