Replacement & Compatibility FAQ
Q: Is the GTN721 the same as the TN721?
A: Yes. GTN721 and TN721 are OEM variant designations for the same TOSHIBA servo power supply module. They are functionally and physically identical in most configurations.
Q: Can I use a third-party replacement for the TN721?
A: Potentially, but only after thorough engineering verification of voltage ratings, current capacity, connector pinout, and control signal compatibility. We recommend using the original TOSHIBA part to avoid system faults.
Q: How long does shipping take?
A: Domestic (China): 2–5 business days. International: 5–15 business days depending on destination and shipping method.
Q: Do you provide a warranty?
A: Yes. Please refer to our store warranty policy or contact support for details specific to this unit’s condition (new/refurbished/surplus).
Q: Can you help me find an equivalent if TN721 is out of stock?
A: Absolutely. Contact our technical team with your system details and we will identify a verified compatible alternative.
