Rockwell’s parts documentation specifically groups 1336-BDB-SP11A and 1336-BDB-SP11C as obsolete versions and identifies 1336-BDB-SP11D as the replacement. The replacement is specified for 1336STE 230 V, 7.5 HP, Series C and later, and 1336F 230 V, 7.5 HP, Series A and later.

 

Product Introduction

The Allen-Bradley 1336-BDB-SP11C is a legacy gate-driver printed circuit board used within the Allen-Bradley 1336 drive family. The board belongs to the drive’s power-control architecture rather than the operator interface or external control-I/O system. Its function is associated with driving the semiconductor switching stage that produces the controlled motor output.

This is a board-level service component, so correct identification matters more than physical fit. Rockwell’s official parts list establishes that the SP11C is an obsolete Series C board, with 1336-BDB-SP11D identified as its replacement.

Application Scenarios & Field Pitfalls — Engineer’s Perspective

Engineering Pain Point

A failed gate-driver board can cause an otherwise healthy 1336 drive to report power-stage faults, fail to start, or exhibit abnormal output behavior. Replacing the PCB without confirming the exact drive voltage, horsepower, frame, and series can result in an electrically incompatible repair.

Typical Applications

  • Allen-Bradley 1336 AC drive repair
  • Legacy 1336STE drive maintenance
  • 1336F drive board-level service
  • Replacement of failed gate-drive circuitry in compatible 7.5 HP drive configurations

Technical Pitfalls to Avoid

  1. Do not confuse SP11C with every SP11 variant.
    The suffix letter is important. Rockwell specifically identifies SP11A and as obsolete, with SP11D as the replacement.
  2. Do not rely on third-party voltage descriptions without checking the drive nameplate.
    Some online listings associate 1336-BDB-SP11C with 460 V applications, but Rockwell’s official replacement documentation identifies SP11D as 230 V, 7.5 HP. The actual drive catalog number and original PCB marking should therefore control the replacement decision.
  3. Replacement is not simply a connector-for-connector exercise.
    Confirm the complete 1336 drive catalog number, input voltage, horsepower, frame, series, and board revision before installing an SP11D replacement.
  4. Treat the board as a high-voltage power-electronics component.
    A 1336 drive can retain hazardous DC-bus voltage after incoming power has been removed. Proper discharge verification and electrical safety procedures are required before accessing or replacing the internal PCB.

 

Related Products

  • 1336-BDB-SP11D — OEM-listed replacement for SP11A/; specified as a 230 V, 7.5 HP gate-driver PCB for applicable 1336STE and 1336F drives.
  • 1336-BDB-SP1D — Gate-driver PCB for another 1336/8720MC power rating; not automatically interchangeable with SP11D. Rockwell identifies it for 8720MC-B014, 7.5 HP.
  • 1336-BDB-SP12D — 230 V, 10 HP gate-driver PCB for compatible 1336STE/1336F configurations.
  • 1336-BDB-SP13D — 230 V, 15 HP gate-driver PCB for compatible 1336STE/1336F configurations.
  • 1336-BDB-SP18D — Higher-power gate-driver PCB used in 1336/8720MC applications; rating and host drive must be matched before substitution.
  • 1336-BDB-SP20 — Base driver board within the 1336 spare-parts family; function differs from the SP11 series.
  • 1336F-MCB-SP1E — Main control board for 1336F drives; it is a control PCB rather than the gate-driver board.
  • 1336-PB-SP series — Precharge/power-related boards used in various 1336 drive configurations; these should not be confused with the gate-driver PCB.

 

Procurement & Replacement Check

For an Allen-Bradley 1336-BDB-, verify the following before purchasing or installing a replacement:

  • Exact PCB marking:
  • Original Series C designation
  • Complete 1336 drive catalog number
  • Drive voltage
  • Drive horsepower
  • Drive frame
  • 1336STE or 1336F family
  • Drive series/revision
  • Original PCB connectors and component layout
  • OEM replacement reference: 1336-BDB-SP11D
  • Whether the replacement board is new, surplus, or previously serviced

Recommended procurement description:

Allen-Bradley Gate Driver PCB, Series C, Legacy 1336 AC Drive Power-Stage Driver Board, Obsolete OEM Version, Replaced by 1336-BDB-SP11D.

Important procurement note: Do not describe the simply as a generic “1336 drive board.” It is specifically a gate-driver PCB, and the exact drive voltage and horsepower are critical to compatibility. Rockwell’s own parts list should take precedence over reseller descriptions when the two disagree.
