⚠️ Note: Parameter migration from 1305 to PowerFlex series requires re-commissioning via DriveExecutive or Studio 5000 software.
③ Cross-Brand Alternatives — Functionally equivalent drives from other manufacturers. Suitable when OEM sourcing is unavailable or cost is a primary constraint.
- Siemens SINAMICS G110 (6SL3211-0AB13-7UA1) — 0.37 kW, 200–240 VAC; comparable V/Hz control. Verify terminal layout before installation.
- Schneider Electric ATV12H037M2 — 0.37 kW, single-phase input; suitable for light-duty conveyor and pump applications.
- Mitsubishi FR-D720-0.4K — 0.4 kW, 200 VAC class; advanced sensorless vector control available.
⚠️ Cross-brand substitution requires full electrical verification, parameter reconfiguration, and system commissioning. Konmask recommends consulting our engineers before proceeding.

Selection Guide
Answer these three questions to confirm the right drive for your application:
- Voltage & Phase Match: Is your supply 200–240 VAC single-phase or three-phase? The 1305-BA03A supports both — confirm your panel supply before ordering a replacement.
- Power Rating Alignment: Is your motor rated at 0.37 kW / 0.5 HP? Upsizing or downsizing the drive rating will affect motor protection and performance.
- Communication Protocol: Does your system use DeviceNet for speed reference or diagnostics? If yes, ensure any equivalent model supports the same network protocol.

Replacement & Compatibility FAQ
Q1: What is a direct replacement for the Allen-Bradley 1305-BA03A?
The most compatible replacement within the Allen-Bradley ecosystem is the PowerFlex 4 (22A-D2P3N104), which matches the voltage class and power rating while offering enhanced diagnostics. For a true drop-in substitute with identical form factor, a refurbished OEM 1305-BA03A is the safest option.
Q2: Is the Allen-Bradley PowerFlex 40 compatible with 1305-BA03A wiring?
The PowerFlex 40 is functionally equivalent in terms of electrical ratings but uses a different terminal layout. Most control wiring is compatible with minor modifications; however, full recommissioning is required. Konmask provides pre-sales wiring comparison support.
Q3: Can a Siemens or Schneider drive substitute for the 1305-BA03A?
Yes — cross-brand equivalents such as the Siemens SINAMICS G110 or Schneider ATV12 can substitute for the 1305-BA03A in terms of electrical performance. However, they are not plug-and-play replacements: parameter configuration, terminal mapping, and system commissioning are required. Contact Konmask for a compatibility assessment before proceeding.
