Mitsubishi Alternator 24V 100A A4TR5191AMA

This Mitsubishi alternator is a new 24V, 100A unit with part number A4TR5191AMA. It is listed as a twin leg alternator mount with an internal regulator, and it suits Mitsubishi applications. The pulley is 8 groove with an outside diameter of 72mm, which is a useful check when matching the existing drive arrangement on the vehicle or engine.

The unit is described as small size with high output, with a minimum number of parts and low noise characteristics for wind and electromagnetic noise. Those points can matter where space is tight and a tidy electrical installation is required, but the practical fit still comes down to the mounting dimensions, pulley setup and electrical requirements. This alternator is rated at 24V and 100 amp, so it should only be considered where that charging specification is appropriate.

For identification and ordering, the main reference details are Mitsubishi, alternator, 24V, 100A, and A4TR5191AMA. The listed weight is 7kg, and the regulator is internal. If you are replacing an existing unit, compare the part number, mounting style and the measured dimensions before purchasing so you are not relying on appearance alone.

Application and Buying Notes

The most important checks on this alternator are the 24V system voltage, 100A output rating, and the A4TR5191AMA part number. If the vehicle is not set up for 24V charging, or if the existing alternator uses a different output requirement, this unit is not the right match. The internal regulator and twin leg mount should also be compared with the current unit before purchase.

Mounting dimensions are often the deciding factor in a replacement job. This alternator lists inside mounting legs at 70.5mm, mount centres C at 130mm, mount centres B at 128mm, and mount centre to centre at 182mm. The pivot hole diameter is M10 x 1.5 and the adjusting hole diameter is 10mm, so the physical bracket points need to line up with the vehicle or bracket arrangement already in place.

Pulley details matter just as much as electrical specs. The pulley is an 8 groove type with a 72mm outside diameter, so the existing belt system should be checked carefully. If the belt count, pulley diameter or offset does not match what is already fitted, the alternator may not align correctly even if the mounting points appear close.

This unit is described as new and carries a 2 years / 400,000km warranty. That gives a clear service expectation, but the warranty does not replace the need to confirm compatibility first. For replacement work, the safest approach is to compare the part number, mounting measurements, pulley section and voltage rating against the original component before installation.

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 A4TR5191AMA 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.

Additional published details for cross-checking include Weight 7kg, Product Group 1 ROTATING ELECTRICAL, Part No. A4TR5191AMA, Brand MITSUBISHI, Description Mitsubishi Alternator 24V 100A, Adjusting Hole Diameter 10, Mount Centres B 128mm, Pin Code IR36, Power Rating (Amp) 100, Pulley Section 8 Groove.

Mitsubishi Alternator 24V 100A. Part number A4TR5191AMA should be checked first. Listed voltage is 24. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number A4TR5191AMA, 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 24 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SCANIA 4 - SERIES, SCANIA 4 - SERIES 1995, SCANIA 4 - SERIES 1996, SCANIA 4 - SERIES 1997. 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 by checking the part number A4TR5191AMA, the 24V 100A specification, the twin leg mounting dimensions, and the 8 groove pulley details against the vehicle’s existing alternator and application requirements before ordering.
