Allen-Bradley 1336-QOUT-SP19A Original Spare 1336 PLUS Compatible

Product Overview

Allen-Bradley 1336-QOUT-SP19A Original Spare 1336 PLUS Compatible

When a 1336 PLUS AC drive trips on an output fault or fails to deliver reliable switching signals to the motor, the transistor output assembly is almost always the first component under scrutiny. The Allen-Bradley 1336-QOUT-SP19A is the factory-original transistor output assembly designed specifically for the 1336 PLUS drive family — a workhorse platform that continues to power conveyors, pumps, compressors, fans, and process lines across manufacturing facilities worldwide. Keeping a verified spare of this assembly on the shelf is one of the most cost-effective decisions a maintenance team can make, because when this board fails, the entire drive goes offline until it is replaced.

The 1336 PLUS platform was engineered for demanding industrial environments, and the transistor output assembly sits at the heart of its power conversion stage. It interfaces directly with the drive’s gate driver circuitry and the IGBT power module stack, translating control signals from the main control board into precise switching commands. A degraded or failed 1336-QOUT-SP19A typically manifests as overcurrent faults, erratic motor behavior, asymmetric output voltage, or a complete drive shutdown. Because the 1336 PLUS does not offer hot-swap capability on this assembly, replacement requires a planned shutdown — making pre-stocked spares essential for any facility running this drive in a critical application.

At TOPNLMS, every 1336-QOUT-SP19A unit is sourced from verified supply channels, individually inspected, and function-tested before shipment. We ship globally from Xiamen with full export documentation, and each unit is backed by a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions.

Preventive Maintenance Strategy

Experienced maintenance engineers know that a transistor output assembly failure rarely occurs in isolation. The 1336 PLUS drive is a tightly integrated system, and stress on the output stage often reflects broader issues in the surrounding electrical circuit. When scheduling a replacement of the 1336-QOUT-SP19A, it is best practice to simultaneously inspect and — where service hours indicate — replace several adjacent components to maximize the value of the planned downtime window.

Begin with the 1336 PLUS main control board (such as the 1336-BRF-SP1 or equivalent series control assembly), which coordinates gate firing signals to the output assembly. A degraded control board can send malformed switching commands that accelerate wear on the transistor output stage. Next, inspect the 1336 PLUS power interface board and the associated IGBT power module — these components share the thermal and electrical load with the output assembly and are subject to the same aging mechanisms.

The 1336 PLUS precharge board is another component worth evaluating during the same maintenance window. Precharge failures can subject the output assembly to voltage spikes during startup, shortening its service life. Similarly, the 1336 PLUS fan assembly and internal cooling components should be checked: inadequate airflow is one of the leading causes of premature transistor output failure in enclosed drive cabinets.

On the signal side, verify the integrity of the 1336 PLUS I/O option board (such as the 1336-GM6 or 1336-MOD-L11 communication module) and the associated programming cable used for drive configuration and diagnostics. If the drive communicates over DeviceNet or DH-485, inspect the network communication module for corrosion or loose terminations, as communication faults can mask underlying output assembly issues during troubleshooting.

Finally, review the condition of the terminal block assemblies and output power wiring at the drive’s U, V, and W terminals. Loose or corroded output connections create resistance that increases thermal stress on the transistor output assembly. Pairing the 1336-QOUT-SP19A replacement with a full terminal inspection and torque verification ensures the new assembly operates within its rated parameters from day one.

Strategic Replacement Solutions

The Allen-Bradley 1336 PLUS series has been in service for decades, and while Rockwell Automation has transitioned its current portfolio toward the PowerFlex 400, PowerFlex 525, and PowerFlex 755 families, many facilities continue to operate 1336 PLUS drives because the cost and complexity of a full drive replacement outweighs the benefit — particularly when the existing mechanical and electrical infrastructure was designed around the 1336 PLUS form factor.

Stocking the 1336-QOUT-SP19A as a critical spare is the most direct strategy for extending the operational life of these drives without committing to a full system upgrade. A single unplanned drive failure on a critical production line can cost far more in lost output than the price of maintaining a spare parts inventory. For facilities running multiple 1336 PLUS units, a tiered spare parts strategy — with at least one transistor output assembly, one control board, and one power module per drive frame size — provides meaningful protection against extended downtime.

For facilities that are planning a phased migration to newer drive platforms, the 1336-QOUT-SP19A serves as a bridge component: it keeps existing drives operational during the transition period, allowing engineering teams to schedule upgrades during planned shutdowns rather than emergency replacements. This approach preserves production continuity while the new drive infrastructure — including updated motor cables, conduit routing, and PLC program modifications — is prepared and validated.

TOPNLMS maintains inventory of 1336 PLUS spare assemblies specifically to support this maintenance and transition strategy. Our sourcing team actively monitors global supply channels to ensure availability of components that are no longer in active production, giving your maintenance department a reliable procurement partner for legacy Allen-Bradley drive spares.

Support FAQ

Q1: How do I confirm the 1336-QOUT-SP19A is compatible with my specific 1336 PLUS drive?
The 1336-QOUT-SP19A is designed for the 1336 PLUS drive family. Compatibility depends on your drive’s catalog number and firmware revision. Check the drive nameplate for the full catalog number (e.g., 1336F-BRF75-AE-DE) and cross-reference with the 1336 PLUS spare parts catalog or contact TOPNLMS with your drive’s catalog number for confirmation before ordering.

Q2: What is the shelf life and storage recommendation for this spare part?
When stored in a clean, dry environment at 15–35°C with relative humidity below 75% (non-condensing), the 1336-QOUT-SP19A has an effective shelf life of 5–7 years. Store in anti-static packaging away from direct sunlight and magnetic fields. TOPNLMS ships all units in protective ESD packaging suitable for long-term storage.

Q3: What pre-shipment testing does TOPNLMS perform on this assembly?
Each unit undergoes visual inspection for physical damage, component-level continuity testing, and functional verification of the transistor switching circuit prior to shipment. Units that do not pass all test criteria are quarantined and not sold. A test report is available upon request for critical procurement applications.

Q4: What does the 12-month warranty cover, and how is a warranty claim processed?
The 12-month warranty covers manufacturing defects and functional failures under normal operating conditions — defined as installation and use within the component’s rated electrical and environmental specifications. It does not cover damage from incorrect installation, overvoltage events, or physical mishandling. To initiate a warranty claim, contact [email protected] with your order number, a description of the failure, and any available fault codes from the drive. TOPNLMS will arrange return shipping and provide a replacement or refund within 10 business days of receiving the returned unit.
