Compatible Replacement & Equivalent Models
When the original 1336-BDB-SP29D is unavailable or discontinued, the following models may serve as direct or functional replacements. Always verify firmware revision and drive frame size before substitution.
- 1336-BDB-SP29D — OEM original (this listing)
- 74101-169-53 — Rockwell internal cross-reference / alternate part number
- 1336-BDB-SP29 — Earlier revision; confirm compatibility with drive firmware
- 1336-BDB-SP29E / SP29F — Later revisions; may require firmware update on host drive
- Third-party equivalent boards — Available for select frame sizes; contact Konmask for cross-reference verification
Note: Revision suffix (D, E, F…) may affect gate-drive timing parameters. Always match or confirm with Rockwell Automation’s cross-reference tool or contact our technical team.
Why Choose the Original Model
- OEM-matched performance — Designed and validated specifically for 1336 PLUS drive architecture; no derating or firmware workarounds required.
- Plug-and-play replacement — Direct board swap with no mechanical modification; preserves existing wiring and connector layout.
- Proven field reliability — Widely deployed in heavy industrial environments including steel mills, water treatment, and material handling.
- Full Rockwell ecosystem support — Compatible with RSLogix, DriveExplorer, and Connected Components Workbench for parameter backup and restore.
- Regulatory compliance — Meets UL, CE, and RoHS requirements as part of the 1336 PLUS drive system.
Typical Applications
- AC variable-frequency drive (VFD) repair and board-level replacement for 1336 PLUS series
- Pump and fan speed control in HVAC and water/wastewater systems
- Conveyor and material handling drive maintenance
- Compressor and blower control in process industries (oil & gas, chemical, food & beverage)
- Machine tool spindle drives and CNC auxiliary axes
- Preventive maintenance stock for facilities running large 1336 PLUS drive populations
System Compatibility
| Drive Series | Compatible | Notes |
| 1336 PLUS (1336S) | ✅ Yes | Primary target platform |
| 1336 PLUS II (1336F) | ⚠️ Verify | Confirm frame size and revision |
| 1336 IMPACT (1336E) | ⚠️ Verify | Different control architecture; consult datasheet |
| PowerFlex 400 / 700 | ❌ No | Different platform; not interchangeable |
| 1305 / 1336 FORCE | ❌ No | Separate board families |
Selection Guide
Use the following decision flow to confirm the correct board for your application:
- Identify drive catalog number — Locate the nameplate on your 1336 PLUS drive (e.g., 1336S-BRF30-AN-EN).
- Record firmware revision — Use DriveExplorer or the drive keypad to read the firmware version.
- Match frame size — The BDB board family covers specific HP/kW ranges; confirm your drive’s frame letter (A, B, C, D…).
- Check revision suffix — SP29D is the target revision; SP29E/F are later revisions that may require firmware ≥ a specific version.
- Confirm availability — Contact Konmask with your drive serial number for a definitive cross-reference check.
If you are unsure, send us your drive nameplate photo and we will confirm compatibility at no charge.

Replacement & Compatibility FAQ
Q: Is the 1336-BDB-SP29D the same as 74101-169-53?
A: Yes. 74101-169-53 is Rockwell Automation’s internal manufacturing part number for the same assembly sold under catalog number 1336-BDB-SP29D.
Q: Can I use a SP29E or SP29F revision instead of SP29D?
A: Later revisions are generally backward-compatible but may require a firmware update on the host drive. We recommend confirming with Rockwell’s cross-reference or contacting our team before substituting.
Q: Will this board work on a 1336 PLUS II (1336F) drive?
A: Possibly, depending on frame size and firmware. The 1336F shares some board families with the 1336S but has differences in control architecture. Please provide your drive catalog number for verification.
Q: Do you offer tested/refurbished units?
A: Yes. Refurbished units are fully bench-tested and carry the same 12-month warranty as new surplus stock. Pricing is available on request.
Q: What is your return policy?
A: We accept returns within 30 days for unused, uninstalled boards in original packaging. Tested/installed boards are covered under warranty repair or replacement.
Q: Can you help identify the correct board if I only have the drive serial number?
A: Yes. Email us your drive serial number or nameplate photo and we will cross-reference the correct board part number at no charge.
