OEX Alternator 24V 100A Delco Style DXA9200

The OEX DXA9200 is a new 24V alternator rated at 100A, built in a Delco style and supplied as a twin leg unit with an internal regulator. It is listed with a 22mm shaft diameter, 198mm mount centre to centre, and 101mm inside mounting legs, so the physical mounting dimensions matter as much as the electrical rating when checking replacement suitability.

This alternator is identified as Part No. DXA9200 and OEM Number 03-19011153S. It is described as suiting Delco units, and the fitment data supplied also references a number of HITACHI applications. Because alternator housings and mounting arrangements can vary even within similar-looking machines, the part number and mount measurements should be checked carefully before ordering.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. The alternator is backed by a 3yr passenger / 1yr commercial warranty, which gives a clear benchmark for how the unit is supported after purchase.

Application and Buying Notes

Before buying, confirm the alternator on the machine is a 24V Delco style unit and compare the mounting details against this part: twin leg mount, 198mm mount centre to centre, 101mm inside mounting legs, and a 22mm shaft diameter. Those measurements are the quickest way to rule out a mismatch where the electrical rating may look correct but the physical fit is not.

The listed output is 100A, so this unit is aimed at applications that require the same charging capacity. Matching voltage is essential on any 24V system, and the internal regulator type also needs to align with the vehicle or equipment setup. If the original alternator uses a different regulator arrangement or mount style, the replacement should not be assumed to fit.

The supplied fitment references include HITACHI EH600, EH700, EX1100-3, EX1800-2, EX1800-3, EX3500-3, EX550-5, EX550/ LC, EX550BE-5/LC-5, EX700, EX750-5 and EX800H-5. These application names are useful as a reference point, but the part number DXA9200 and OEM number 03-19011153S remain the most reliable checks when confirming compatibility.

If you are replacing a failed alternator, compare the old unit’s tag, case shape, pulley arrangement and mounting points before proceeding. A 24V, 100A alternator in Delco style can still differ in small but important ways, so it is worth verifying the exact machine model and serial details where available, especially on equipment that may have had previous repairs or non-original components fitted.

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 DXA9200 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.

OEX Alternator 24V 100A Delco Style. Part number DXA9200 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. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9200, 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 HITACHI EH600, HITACHI EH600 2006, HITACHI EH700, HITACHI EH700 2004. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by checking Part No. DXA9200, OEM Number 03-19011153S, the 24V 100A rating, and the physical mounting measurements before ordering. Use the listed application references only as guidance and do not rely on appearance alone.
