Note: Always verify PCB revision and firmware compatibility before substitution. Contact Konmask for cross-reference validation.

Why Choose the Original Model

• Guaranteed Compatibility: Factory-matched to 1336 PLUS drive firmware and hardware revisions — no tuning or adaptation required.
• Rockwell Quality Standards: Manufactured under ISO-certified processes with full traceability.
• Warranty Coverage: Original parts maintain drive warranty and Rockwell TechConnect support eligibility.
• Long Service Life: Designed for continuous industrial duty cycles in demanding environments.
• Reduced Commissioning Risk: Eliminates compatibility unknowns that arise with third-party substitutes.

Typical Applications

• MRO (Maintenance, Repair & Overhaul) replacement for failed 1336 PLUS drive boards
• Spare parts inventory for facilities running legacy 1336 PLUS AC drive fleets
• OEM machine builders maintaining 1336 PLUS-based control panels
• System integrators refurbishing or extending the life of existing drive installations
• Industrial sectors: automotive assembly, material handling, HVAC, water/wastewater, pulp & paper, mining

System Compatibility

Compatible Platform	Notes
Allen-Bradley 1336 PLUS	Primary compatible drive family
Allen-Bradley 1336 PLUS II	Verify board revision before ordering
Rockwell Automation DriveTools SP	Used for parameter backup/restore during board swap
DeviceNet / DPI Communication	Dependent on specific board variant (GT3EN vs LM3EN)

Not compatible with 1336 IMPACT, 1336 FORCE, or PowerFlex series without engineering review.

Selection Guide

Use the following criteria to select the correct module for your application:

• Step 1 — Identify your drive nameplate: Confirm the drive is a 1336 PLUS or 1336 PLUS II series.
• Step 2 — Locate the failed board: Match the board label to 1336T-GT3EN (gate/interface) or 1336T-LM3EN (logic/main) to confirm function.
• Step 3 — Check PCB revision: Revision letters (e.g., Rev A, Rev B) affect compatibility. Provide this to Konmask when ordering.
• Step 4 — Confirm drive HP/kW rating: Some board variants are rating-specific. Share the full drive catalog number.
• Step 5 — Choose condition: New OEM for critical uptime applications; surplus/refurbished for budget-sensitive or legacy installations.

Quality Assurance & Sourcing

• Authorized & Verified Supply Chain: All modules sourced from authorized distributors, factory surplus, or certified MRO channels.
• Anti-Counterfeit Inspection: Every unit undergoes visual, dimensional, and functional verification before shipment.
• Traceability Documentation: Certificate of conformance and test reports available on request.
• Secure Packaging: ESD-safe packaging with moisture barrier for international shipment.
• Global Logistics: DHL / FedEx express available; export documentation provided for cross-border orders.

Replacement & Compatibility FAQ

Q: Can 1336T-GT3EN and 1336T-LM3EN be used interchangeably?
A: No. GT3EN and LM3EN refer to different board functions within the drive. Always match the board label on the failed unit.

Q: Is 74101-954-53 still in production by Rockwell?
A: This part is from the legacy 1336 PLUS series. Availability may be limited to surplus or refurbished stock. Contact us to confirm current inventory.

Q: Do I need to re-program the drive after replacing this board?
A: Yes. Parameter backup via DriveTools SP is strongly recommended before board replacement. Some parameters may need to be re-entered after swap.

Q: Can Konmask verify compatibility before I order?
A: Yes. Provide your full drive catalog number and PCB revision, and our team will confirm compatibility before invoicing.

Q: What warranty applies to surplus or refurbished units?
A: Konmask provides a 90-day functional warranty on all tested surplus and refurbished modules. New OEM units carry the standard Rockwell warranty.
