Allen-Bradley 1336F-MCB-SP2L Control Board (164989) | Replacement, Equivalent & Selection Guide
The Allen-Bradley 1336F-MCB-SP2L (Catalog Ref: 164989) is the main control board for the Rockwell Automation 1336 PLUS II series AC variable frequency drive. This board serves as the central intelligence of the drive — managing speed reference processing, fault diagnostics, parameter storage, and communication with operator interfaces. When this board fails, the entire drive becomes inoperable, halting production lines, conveyor systems, pump stations, and HVAC equipment. Sourcing a verified replacement quickly is critical to minimizing unplanned downtime.
As a specialist in industrial automation spare parts, Konmask.com stocks and sources the 1336F-MCB-SP2L to support maintenance engineers and procurement teams worldwide. Whether you need an OEM replacement, a tested-used unit, or guidance on compatible alternatives, this page provides the complete selection reference.

Compatible Replacement & Equivalent Models
When the original 1336F-MCB-SP2L is unavailable or cost-prohibitive, the following options may be evaluated by a qualified engineer:
- Direct OEM Replacement: 1336F-MCB-SP2L (same catalog number, different production date codes) — fully interchangeable
- Revision Variants: Check suffix letters (e.g., SP2L vs SP2) — confirm firmware and hardware revision compatibility with your drive’s existing boards before substitution
- Drive-Level Replacement: If the MCB is no longer available, a complete 1336 PLUS II drive replacement or migration to the PowerFlex 400 / PowerFlex 525 series may be considered as a long-term upgrade path
- Third-Party Repair: Board-level repair by a certified Rockwell service center is a viable alternative when OEM stock is exhausted
Important: Always verify part number suffix, firmware version, and drive frame size compatibility before installing any replacement board. Konmask’s technical team can assist with cross-reference validation — contact us before ordering if uncertain.
Why Choose the Original Model
- Guaranteed Compatibility: The 1336F-MCB-SP2L is factory-matched to the 1336 PLUS II drive architecture — no firmware conflicts, no parameter migration issues
- Preserved Drive Functionality: All original features (PID control, fault logging, communication ports) remain fully operational
- Reduced Commissioning Risk: Drop-in replacement with no re-engineering required
- Regulatory Compliance: Maintains CE/UL certification integrity of the original drive installation
- Long Service Life: OEM boards are designed and tested to the same environmental and electrical standards as the original drive
Typical Applications
- Industrial conveyor and material handling systems
- Pump and fan variable-speed control in water treatment and HVAC
- Compressor drive control in oil & gas and chemical processing
- Extruder and mixer drives in plastics and food manufacturing
- Crane and hoist drive systems in heavy industry
- General-purpose AC motor speed control in discrete manufacturing
System Compatibility
- Drive Series: Allen-Bradley 1336 PLUS II (1336F prefix)
- Communication Options: Compatible with 1336F communication adapter boards (DeviceNet, ControlNet, Ethernet/IP — verify per drive configuration)
- HIM Compatibility: Works with 1336-GM1, 1336-GM2, and compatible Human Interface Modules
- PLC Integration: Designed for integration with Allen-Bradley ControlLogix, CompactLogix, and SLC 500 controllers via supported network adapters
- Power Range: Applicable across the 1336 PLUS II horsepower range — confirm frame size and power board compatibility for your specific drive
Selection Guide
Use the following checklist to confirm the 1336F-MCB-SP2L is the correct part for your application:
- ✅ Confirm drive nameplate reads 1336F (1336 PLUS II series)
- ✅ Locate the existing MCB and verify the catalog label reads 1336F-MCB-SP2L or reference number 164989
- ✅ Note the firmware revision on the existing board (if readable) and request a matching or compatible revision
- ✅ Check whether any communication adapter boards are installed — these are separate from the MCB and do not need replacement unless also damaged
- ✅ If upgrading from a different 1336 PLUS II MCB variant, consult Rockwell publication 1336F-UM001 or contact Konmask for cross-reference support

Replacement & Compatibility FAQ
- Q: Can I use a 1336F-MCB-SP2 instead of the 1336F-MCB-SP2L?
- A: The suffix letter may indicate a hardware or firmware revision difference. We recommend contacting Konmask or Rockwell Automation to confirm interchangeability for your specific drive serial number before substituting.
- Q: Is this board compatible with the original 1336 PLUS (non-II) series?
- A: No. The 1336F prefix designates the 1336 PLUS II series. The original 1336 PLUS uses different MCB part numbers. Do not interchange between series.
- Q: Can I send my faulty board for repair instead of purchasing a replacement?
- A: Yes. Konmask can facilitate board-level repair referrals through our network of certified repair centers. Contact us with your board’s fault symptoms for an assessment.
- Q: What is the lead time for a new OEM unit?
- A: Lead times vary by stock availability. Surplus units typically ship within 3–5 business days. New OEM units may require 2–8 weeks depending on Rockwell’s current availability. Contact us for a real-time quote.
- Q: Do you provide export documentation for international orders?
- A: Yes. We provide commercial invoices, packing lists, and certificates of origin. Additional documentation (e.g., CITES, end-user certificates) can be arranged upon request.
