Compatible Replacement & Equivalent Models
When the original HW1382455-C is unavailable or lead times are extended, the following models may serve as functional equivalents — subject to axis position and torque verification:
- A97L-0318-0239#430Z-126 — OEM cross-reference, same mechanical interface
- HW1382455-A / HW1382455-B — Earlier revision variants; confirm compatibility with robot firmware version
- Nabtesco RV-series reducers — Third-party equivalent for select axis positions; requires dimensional verification
- Sumitomo Cyclo equivalents — Alternative cycloidal reducer; consult Yaskawa service manual before substitution
Always verify gear ratio, flange dimensions, and rated torque before substituting any reducer. Konmask.com recommends using OEM parts for safety-critical joints.
