Allen-Bradley 1336-BDB-SP30D PCB Gate Drive Board | Replacement, Equivalent & Selection Guide
The Allen-Bradley 1336-BDB-SP30D is a PCB Gate Drive Board designed for use within the Rockwell Automation 1336 PLUS / PLUS II series AC variable frequency drives. This board serves as the critical interface between the drive’s control logic and the IGBT power module, generating and isolating gate pulses to ensure precise, safe switching of the inverter bridge. It is a core spare part for maintaining uptime in industrial motor control applications.
Selection Background: Why Replacement & Equivalent Models Matter
When the original 1336-BDB-SP30D reaches end-of-life, becomes obsolete, or is unavailable through standard distribution channels, engineers and procurement teams must evaluate replacement and equivalent options to avoid costly production downtime. Understanding which substitute or drop-in replacement is compatible — and under what conditions — is essential for safe and reliable operation. This guide captures the high-intent search queries around 1336-BDB-SP30D replacement, equivalent gate drive board, and cross-brand substitute to help you make an informed selection decision.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
These are OEM-sourced or remanufactured boards with identical part numbers or Rockwell-approved revision equivalents. They share the same PCB layout, connector positions, and firmware compatibility.
- 1336-BDB-SP30D (OEM new / surplus)
- 1336-BDB-SP30D Series B / C revisions (verify firmware compatibility with drive series revision)
2. Functional Equivalents
Boards from the same 1336 drive family that share gate drive architecture. Substitution requires verification of drive frame size, power rating, and connector mapping.
- 1336-BDB-SP20D — lower power rating variant; confirm IGBT module match before substituting
- 1336-BDB-SP40D — higher power variant; may require firmware and hardware adaptation
3. Cross-Brand Alternatives
Third-party or aftermarket gate drive boards designed to substitute for the 1336-BDB-SP30D. These require careful validation of isolation voltage, gate resistance values, and signal timing before installation. Always perform a bench test prior to live deployment.
- Aftermarket remanufactured 1336-BDB-SP30D (tested, with warranty) — available via Konmask
- Custom gate drive PCB equivalents — consult Konmask engineering for cross-reference validation
⚠️ Note: Cross-brand substitution must be validated by a qualified drive technician. Incorrect gate drive boards can damage IGBT modules and void drive warranties.
Why Choose the Original Model
- Precision Timing: Factory-calibrated gate pulse timing ensures optimal IGBT switching efficiency and minimal switching losses
- Certified Isolation: Meets Rockwell Automation isolation and dielectric strength specifications for the 1336 drive platform
- Plug-and-Play Compatibility: Exact connector pinout and PCB footprint — no wiring modifications required
- Firmware Alignment: Fully compatible with 1336 PLUS / PLUS II drive firmware revisions without parameter re-tuning
- Technical Support: Backed by Rockwell Automation documentation and Konmask’s application engineering team
- Warranty Coverage: Genuine and remanufactured units supplied by Konmask include quality warranty and traceability documentation
Typical Applications
- Manufacturing: AC motor speed control on conveyor lines and assembly equipment using 1336 PLUS drives
- HVAC Systems: Variable speed fan and pump control in commercial building automation
- Water & Wastewater: Pump station VFD maintenance requiring gate drive board replacement
- Oil & Gas: Compressor and blower motor drives in upstream and midstream facilities
- Mining: Crusher and conveyor drive systems requiring high-reliability spare parts
- Food & Beverage: Mixer and agitator motor control in hygienic processing environments
System Compatibility
- 1336 PLUS Drive (1336F-xxxxx): Primary compatible platform — gate drive board interfaces directly with IGBT power module
- 1336 PLUS II Drive (1336S-xxxxx): Compatible with matching frame size and power rating
- IGBT Power Module (1336-MOD-xxx): Must match gate drive board voltage and current rating
- Control Board (1336-BDB-SP10D): Upstream signal source — verify signal interface compatibility
- Precharge Board (1336-BDB-SP20D): Operates in conjunction during drive startup sequence
- Snubber / Gate Resistor Assembly: Must be inspected and replaced if gate drive board failure was caused by IGBT shoot-through
Selection Guide
Answer these three questions to confirm the right gate drive board for your application:
- What is your drive’s exact catalog number and series revision? (e.g., 1336F-BRF30-AN-EN Series C) — This determines which board revision is compatible and whether firmware alignment is required.
- What is the drive’s power rating and frame size? — Gate drive boards are power-rated; using an undersized or oversized equivalent can cause IGBT failure or nuisance faults.
- Is a direct drop-in replacement required, or is a functional equivalent acceptable? — If the system is under warranty or in a regulated environment, only OEM or certified remanufactured parts should be used.

Replacement & Compatibility FAQ
Q: Can I use a 1336-BDB-SP20D to replace the 1336-BDB-SP30D?
A: The SP20D is a lower power-rated equivalent and is not a direct substitute for the SP30D in drives rated at 30 HP or above. Using an undersized gate drive board risks IGBT overcurrent faults. Always match the power suffix to your drive’s HP rating.
Q: Is the 1336-BDB-SP30D compatible with both 1336 PLUS and 1336 PLUS II drives?
A: Yes, the SP30D is compatible with both platforms at the matching frame size and power rating. However, always verify the drive’s series revision and firmware version before installation, as minor connector or signal differences may exist between revisions.
Q: Are there cross-brand or aftermarket equivalents that can substitute for the 1336-BDB-SP30D?
A: Aftermarket remanufactured equivalents are available and can be a cost-effective substitute when OEM new stock is unavailable. Konmask supplies tested remanufactured units with warranty. Third-party cross-brand alternatives exist but require engineering validation — contact us for a compatibility assessment before ordering.
