Compatible Replacement & Equivalent Models
The following models are commonly evaluated as replacements or alternatives to the 150-F135NBDB. Always verify electrical ratings and communication protocol before substitution.
- 150-F135NBD – Same frame, without internal bypass; requires external bypass contactor
- 150-F135NBDB-S – With Safe-Off option; suitable for SIL 2 / PLd safety applications
- 150-F180NBDB – Next frame up (180A); use when motor FLA exceeds 135A
- 150-F108NBDB – Lower rating (108A); suitable for smaller motor loads
- SMC-3 / SMC-50 – Older Allen-Bradley SMC series; not direct drop-in, requires wiring adaptation
- Siemens 3RW44 – Third-party equivalent soft starter; different communication protocol
- ABB PSE / PSTB Series – Alternative brand soft starters; verify bypass and control voltage compatibility
- Schneider Electric Altistart 48 – Comparable soft starter; different mounting and wiring

Selection Guide
Use the table below to select the correct SMC Flex model for your application:
| Parameter | Specification | Recommended Model |
|---|---|---|
| Motor FLA ≤ 108A, 480V, DeviceNet, bypass | 108A / 480V | 150-F108NBDB |
| Motor FLA ≤ 135A, 480V, DeviceNet, bypass | 135A / 480V | 150-F135NBDB ✓ |
| Motor FLA ≤ 180A, 480V, DeviceNet, bypass | 180A / 480V | 150-F180NBDB |
| Safety application (SIL 2 / PLd required) | 135A / 480V + Safe-Off | 150-F135NBDB-S |
| No network communication required | 135A / 480V, standalone | 150-F135NB |
Note: Always confirm motor nameplate FLA and service factor before selecting controller rating. Derate for high-altitude or high-ambient-temperature installations per Rockwell publication 150-UM009.

Replacement & Compatibility FAQ
Q: Can I replace a 150-F135NBD with a 150-F135NBDB?
A: Yes. The NBDB adds an internal bypass contactor. If your panel already has an external bypass, you can use either model, but the NBDB simplifies wiring.
Q: Is the 150-F135NBDB compatible with EtherNet/IP?
A: Not natively. It uses DeviceNet. Add the 150-SM4 EtherNet/IP communication module for IP-based network integration.
Q: Can a Siemens 3RW44 replace the 150-F135NBDB directly?
A: Electrically comparable, but the DeviceNet communication and Rockwell software integration will not carry over. Significant reprogramming and wiring changes are required.
Q: What is the warranty on units from Konmask.com?
A: We offer a 12-month warranty on all new OEM units and a 6-month warranty on certified surplus/refurbished units.
Q: Do you provide installation support?
A: Yes. Our technical team can provide wiring diagrams, parameter setup guidance, and commissioning support via email or video call.
