Features:

  • Device quantity: one SGCT
  • Electrical identity: 1500 A and 6500 V
  • OEM successor: Direct Replacement 81001-451-81-R
81001-451-61-R identifies one high-current SGCT rather than a matched group.

Rockwell Automation provides a successor code, allowing the material change to be documented against the legacy device.

Device-position evidence and official troubleshooting results should stay with that cross-reference throughout the outage.

Rockwell Automation lists 81001-451-61-R as discontinued; availability depends on Apter Power sourcing confirmation.

Legacy device identity

  • Quantity: record one SGCT device.
  • Current: retain the 1500 A configuration.
  • Voltage: retain the 6500 V configuration.
  • Position: map the failed device within the drive.

Official successor control

  • Legacy code: preserve 81001-451-61-R.
  • Successor: Rockwell Automation names 81001-451-81-R.
  • Category: the published relationship is Direct Replacement.
  • Release: approve the change through site engineering.

Evidence before substitution

  • Resistance: retain device and circuit measurement results.
  • Gate path: complete the official gate-cathode check.
  • Firing: use the approved Rockwell Automation procedure.
  • Fiber: rule out the optical path before final diagnosis.
Description
One high-current semiconductor is the order configuration for 81001-451-61-R. Rockwell Automation identifies it as a single 1500 A, 6500 V SGCT and lists the exact part as discontinued.

For 81001-451-61-R, the official Direct Replacement is 81001-451-81-R. Applying that relationship still requires the failed device position, rating evidence, and the PowerFlex 7000 troubleshooting results to remain in the engineering record.

The replacement decision for 81001-451-61-R should follow the official resistance, gate-cathode, firing, and fiber-optic checks under the required safe drive condition. Those findings help avoid changing an SGCT when the fault lies elsewhere in the path.

Technical notes
Rockwell Automation directs 81001-451-61-R to 81001-451-81-R as a Direct Replacement. Retain the single-device 1500 A, 6500 V identity, failed position, resistance and firing results, fiber inspection, isolation record, receiving inspection, and cabinet drawing reference before the successor is approved for controlled installation and documented functional acceptance.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which official successor applies when 81001-451-61-R is no longer available?
Rockwell Automation lists 81001-451-81-R as the Direct Replacement, which should be retained with the engineering change record.
How does the single-device identity affect an 81001-451-61-R quotation?
The offer must describe one 1500 A, 6500 V SGCT and must not silently convert the request into a matched-set package.
What diagnostic evidence should precede a decision to replace 81001-451-61-R?
Use official resistance, gate-cathode, firing, and fiber-optic checks, recording the results against the failed device position.
Why should the legacy label remain linked to 81001-451-61-R after its successor is fitted?
It preserves traceability from the original device and fault history to the new material number and acceptance test.
What safety condition governs testing associated with 81001-451-61-R?
Follow the official PowerFlex 7000 procedure and establish the required isolation and stored-energy controls before semiconductor testing.
Which incoming evidence confirms that a proposed 81001-451-61-R successor matches the official path?
Verify the complete 81001-451-81-R label, supplied quantity, physical condition, traceability, and the Rockwell Automation direct-replacement record.
