Product Overview
The 23100-4BA0B is a Nissan OE-spec replacement alternator delivering 12V 120A output with a 6-rib (6PK) pulley, engineered for the Nissan Rogue 2.5 (2014-2020) and Nissan X-Trail (T32_) 2.5 with the 2.5L QR25DE petrol engine. This Mitsubishi-pattern aftermarket unit matches the original charging-system specification for these popular compact-SUV platforms.
Fitted with internal regulator design, this brand-new alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 120-amp rating is factory-correct for the stock electrical load of these SUV platforms, supporting climate control, heated accessories, infotainment and factory electrical equipment.
Key physical specs: net weight 6.2 kg, gross weight 6.5 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The QR25DE Engine Platform and Rogue / X-Trail Charging System
The 2.5L QR25DE is Nissan's mainstay DOHC naturally aspirated petrol engine, powering the Rogue across 2014-2020 production years and the X-Trail T32 platform. All listed trims - S, SV, SL, Special Edition, Advance, Exclusive and Sense - share the same 2.5L engine and 12V 120A 6PK alternator family, so one part number covers the majority of workshop jobs on these model lines.
This unit is specified as 12V 120A, matching the factory charging-system specification of these platforms. The 6-rib pulley matches the original accessory-belt layout, driving alternator, water pump and power-steering pump. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits Nissan Rogue 2.5 and X-Trail T32 2.5 vehicles equipped with the 2.5L QR25DE DOHC petrol engine. Do not rely solely on vehicle model name for fitment validation; always verify engine code, old-part OE number, pulley rib-count and amp label on your original alternator.

Multiple Nissan and supplier OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 23100-4BA0B serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the amperage label on your old alternator: confirm it is rated for 120A. Different amp ratings are not interchangeable.
2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.
3. Confirm engine code is QR25DE 2.5L. Rogue and X-Trail variants with other engines use different alternator assemblies.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 6.2 kg net; significant weight difference indicates wrong assembly.
Application Scenarios
Independent repair shops and Nissan specialists servicing Rogue and X-Trail across North America, Asia-Pacific, Europe, Oceania and Latin-American markets.
Parts counters and jobbers stocking Japanese SUV replacement electrical components.
Vehicle owners restoring and maintaining original-spec Nissan Rogue and X-Trail models.
Used-car export traders supplying pre-owned Nissan vehicles to global secondary markets.
Owners with moderate accessory loads who require a factory-spec charging system.
Note: For vehicles with heavy aftermarket upgrades such as multiple auxiliary lights, high-watt audio or additional accessories, evaluate whether an upgraded high-output alternator will be required instead of this stock-spec 120A unit.
FAQ
Q: Which Nissan models does this alternator fit?
A: It fits Nissan Rogue 2.5 (2014-2020) and Nissan X-Trail T32 2.5 with the QR25DE petrol engine. Always verify against the OE number, pulley and mounting layout of your original alternator before ordering.
Q: My Rogue is the SV trim, will this alternator work?
A: Yes. S, SV, SL, Special Edition, Advance, Exclusive and Sense trims all share the same 2.5L QR25DE engine and the same alternator family.
Q: My old alternator shows OE number 23100-4BA0A or TG12C168, will 23100-4BA0B work?
A: Yes. These numbers belong to the same alternator family, differing only by production revision and market specification. It serves as a direct replacement.
Q: What is the normal charging voltage after installation?
A: With the engine running at idle, battery terminal voltage should read 13.8V-14.5V; at 2000 rpm the target stabilises around 14.0-14.7V.
Q: What is your warranty and lead-time?
A: Goods are in stock with a 10-day dispatch lead-time. A 1-year warranty applies from installation date; warranty excludes damage caused by mis-installation, wrong belt tension, or vehicle-wiring faults.
In Practice
For technicians working on the Nissan Rogue / X-Trail QR25DE platform: Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.
Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Nissan workshop-manual specifications.
On Rogue models fitted with Intelligent Charging or battery-management systems, confirm battery condition and reset procedures after installation where required. Inexperienced home mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle-system components.
