Sydasant 110A 12V Alternator for Nissan 2.5L L4 — 6-Groove Decoupler Pulley, CW Rotation (2007–2015)

The Sydasant 110A 12V alternator is a direct-fit replacement for select Nissan 2.5L models (Altima, Sentra, Rogue, Rogue Select) providing stable electrical output and OEM-compatible mounting.

This replacement alternator is built for Nissan vehicles using the 2.5L L4 engine across model years primarily between 2007 and 2015. It matches common OEM part numbers such as 23100-JA02A and TG12C032, uses a 6-groove decoupler pulley, and supplies 110 amps at 12 volts. The unit is new, constructed with an aluminum housing and thick copper windings with external insulating coating for corrosion resistance and electrical protection.

Will this alternator fit my Nissan Altima, Sentra, or Rogue?

Compatibility depends on engine, trim, production year, and connector type. This Sydasant alternator is designed for specific 2.5L L4 configurations and fits only vehicles with the three-pin electrical connector and matching mounting pattern.

• Altima 2.5L: 2007–2012 (varies by trim; 2013 coupe S only)
• Sentra 2.5L: 2007–2012 (SE-R and SE-R Spec V only)
• Rogue/Rogue Select 2.5L: 2011–2015 depending on model year and trim
• Tip: use a fitment tool (e.g., Amazon Garage) and compare your OEM part number before purchase

What electrical and mechanical specs should I expect?

The unit provides a 12V output at 110 amps with a clockwise rotation and an internal regulator. It uses an IF fan, IR regulator, and a 6-groove decoupler pulley for modern belt drive systems.

Who is this for: This alternator is aimed at owners and mechanics replacing a failing or weak alternator on compatible Nissan 2.5L vehicles who need a direct-fit, OEM-referenced part. Choose this unit if your vehicle uses the 3-pin connector and your OEM part number matches one of the referenced numbers (for example, 23100-JA02A). If you are uncertain about compatibility, verify your vehicle application and connector type before ordering to ensure correct fit and function.
