Allen-Bradley 1336-BDB-SP6A Original Industrial Spare 1336 PLUS Compatible

Product Overview

Allen-Bradley 1336-BDB-SP6A Original Industrial Spare 1336 PLUS Compatible: Sustaining System Stability in Critical Drive Applications

The Allen-Bradley 1336-BDB-SP6A is an original IGBT Gate Driver Board engineered specifically for the 1336 PLUS and 1336 PLUS II series AC variable frequency drives. In industrial environments where unplanned downtime translates directly into production losses and safety risks, having a verified, ready-to-install spare of the 1336-BDB-SP6A on hand is not a luxury — it is a fundamental element of a sound maintenance strategy.

The 1336 PLUS and 1336 PLUS II drive families have been deployed across decades of industrial installations in sectors ranging from oil and gas, water treatment, and mining to automotive assembly and food processing. Many of these systems remain in active service, and the gate driver board is among the highest-wear components in the drive’s power section. When an IGBT gate driver fails, the entire drive goes offline. A pre-stocked 1336-BDB-SP6A eliminates the lead time that would otherwise extend an emergency shutdown into a multi-day or multi-week outage.

At TOPNLMS, every 1336-BDB-SP6A unit is sourced from verified supply channels, individually inspected, and function-tested prior to dispatch. Each unit ships with a 12-month warranty, providing procurement teams and maintenance engineers with the confidence to plan replacements without risk.

Critical Technical Specs

Preventive Maintenance Strategy

A gate driver board failure rarely occurs in isolation. In most field cases, the root cause involves sustained thermal stress, DC bus voltage transients, or accumulated contamination within the drive enclosure. A disciplined preventive maintenance program for 1336 PLUS and 1336 PLUS II drives should treat the 1336-BDB-SP6A replacement as one element of a broader inspection and sparing plan.

During a scheduled shutdown or corrective maintenance event, maintenance engineers should simultaneously inspect the 1336-MOD-D2 power module and associated IGBT stack, as gate driver degradation often correlates with stress on the switching devices themselves. The 1336-BRF-SP1 precharge resistor assembly and 1336-BDB-SP2A control interface board should also be checked for signs of thermal discoloration or connector wear.

On the power supply side, the 1336-PB-SP2 power supply board provides regulated voltage rails to the gate driver and control circuitry; a marginal power supply can cause intermittent gate driver faults that are difficult to diagnose without substitution. Inspecting and, where appropriate, pre-stocking this board alongside the 1336-BDB-SP6A is a recognized best practice in 1336 PLUS maintenance programs.

Within the control cabinet, terminal blocks, cable harnesses, and the 1336-GM-SP1 gate module should be inspected for loose connections and insulation degradation. The 1336-BDB-SP3A dynamic brake driver board is another component that shares the same thermal environment and should be evaluated during any gate driver replacement event. For drives operating in dusty or humid environments, the cooling fan assembly and heat sink should be cleaned and the fan replaced on a scheduled basis — a blocked heat sink is one of the most common contributors to premature IGBT gate driver failure.

For facilities managing multiple 1336 PLUS or 1336 PLUS II drives, a consolidated spare parts kit covering the gate driver board, power supply board, control board, and key interface cables provides the fastest possible mean time to repair (MTTR) and is strongly recommended for any site where drive availability is critical to production continuity. Facilities running mixed Rockwell Automation environments may also wish to maintain spares for related platforms such as the PowerFlex 700 series drive boards and 1336-L4E encoder feedback modules, which share similar maintenance intervals in comparable applications.

Strategic Replacement Solutions

The 1336 PLUS and 1336 PLUS II drive series, while no longer in active production, remain installed in thousands of facilities worldwide. Rockwell Automation’s official end-of-life designation for this platform means that OEM spare parts availability through standard distribution channels is increasingly constrained. The 1336-BDB-SP6A is among the most frequently requested spare parts for this series, and lead times through conventional channels can extend to weeks or months.

Sourcing the 1336-BDB-SP6A through TOPNLMS provides a direct path to verified original spare inventory without the extended lead times associated with OEM back-order queues. Each unit is tested and documented, enabling maintenance teams to proceed with confidence. The board is a direct drop-in replacement for the original installation — no firmware changes, no parameter re-entry, and no compatibility modifications are required. This preserves the existing drive configuration and eliminates the risk and cost associated with a full drive replacement.

For facilities considering a longer-term strategy, maintaining a minimum stock level of one to two 1336-BDB-SP6A units per installed drive reduces emergency procurement pressure and supports a planned replacement cycle. This approach is particularly valuable for multi-drive installations where a single gate driver failure can cascade into broader production disruptions if replacement inventory is not immediately available.

Support FAQ

Q1: Is the 1336-BDB-SP6A compatible with both the 1336 PLUS and 1336 PLUS II drive variants?
Yes. The 1336-BDB-SP6A is the original IGBT gate driver board specified for both the 1336 PLUS and 1336 PLUS II series. It is a direct board-level replacement and does not require any modification to the drive chassis or control wiring.

Q2: What testing is performed before shipment?
Every 1336-BDB-SP6A unit dispatched by TOPNLMS undergoes visual inspection and functional verification prior to packaging. Units that do not meet inspection criteria are not shipped. A 12-month warranty is provided from the date of shipment, covering defects in materials and workmanship under normal operating conditions.

Q3: How should I verify compatibility before installation?
Confirm the drive nameplate identifies the unit as a 1336 PLUS or 1336 PLUS II series drive. Cross-reference the existing gate driver board part number against 1336-BDB-SP6A prior to removal. If you require additional compatibility verification, contact our technical team at [email protected] with your drive nameplate data and we will confirm fitment before order placement.

Q4: What is the recommended inventory strategy for facilities with multiple 1336 PLUS drives?
For facilities operating three or more 1336 PLUS or 1336 PLUS II drives, we recommend maintaining a minimum of one 1336-BDB-SP6A per three installed drives as a standing spare. For critical production lines where drive downtime directly halts output, a one-to-one spare ratio is advisable.
