Compatible Replacement & Equivalent Models
When the original GU-D08 / FGC800B-130DS is discontinued or lead times are unacceptable, the following paths are commonly evaluated:
- Direct OEM Replacement: Allen-Bradley / Rockwell Automation factory-new or factory-refurbished GU-D08 (same P/N 80173-109-01) — drop-in fit, no parameter changes required.
- Aftermarket SGCT Module: Third-party SGCT modules matched to the same voltage class, current rating, and gate-drive interface. Requires engineering validation before installation.
- Upgraded Drive Replacement: In cases where the soft starter platform is end-of-life, a full drive or soft starter upgrade (e.g., Rockwell PowerFlex MV series) may be more cost-effective long-term.
- Equivalent Thyristor Brands: ABB, Infineon (formerly Eupec), Mitsubishi, and Semikron produce SGCT/GCT devices in comparable voltage and current classes — cross-reference by electrical parameters, not part number alone.
⚠ Important: SGCT modules are safety-critical power devices. Always verify electrical parameters, gate-drive compatibility, and thermal interface before substituting any equivalent.
Why Choose the Original Model
- Guaranteed Compatibility: Designed and validated specifically for Rockwell Automation medium-voltage soft starter platforms — no firmware or hardware adaptation needed.
- Proven Reliability: SGCT technology offers low conduction losses, high surge current capability, and robust gate-commutation performance in demanding industrial environments.
- OEM Support: Original parts maintain full Rockwell Automation service and warranty eligibility.
- Reduced Commissioning Risk: Eliminates the engineering effort and liability associated with third-party substitutions in high-voltage systems.
Typical Applications
- Medium-voltage motor soft starters (2.3 kV – 6.6 kV class)
- Rockwell Automation / Allen-Bradley MV drive power stages
- Industrial pump, fan, compressor, and conveyor motor control
- Oil & gas, mining, water treatment, and power generation facilities
- Steel mills and heavy process industries requiring controlled motor acceleration
System Compatibility
The GU-D08 / FGC800B-130DS SGCT module is designed for use within specific Rockwell Automation medium-voltage soft starter and drive platforms. Compatibility depends on:
- The host drive or soft starter chassis model and revision
- Gate-drive board interface (signal levels, timing, and protection logic)
- Thermal management system (heatsink, coolant flow, or forced-air design)
- Firmware version of the control board
Please provide your full system model number and nameplate data when inquiring, so our technical team can confirm fit before shipment.
Selection Guide
Use the following decision framework to select the right solution for your application:
- Step 1 — Confirm the host system: Identify the exact soft starter or drive model, serial number, and revision.
- Step 2 — Verify the failed module P/N: Cross-check GU-D08, 80173-109-01, and FGC800B-130DS against your unit’s bill of materials or service manual.
- Step 3 — Assess condition requirements: Determine whether new OEM, certified refurbished, or tested-used stock meets your uptime and budget requirements.
- Step 4 — Evaluate lead time vs. downtime cost: If OEM lead time exceeds acceptable downtime, discuss aftermarket or refurbished options with our engineering team.
- Step 5 — Request a quotation: Contact Konmask with your system details for a tailored recommendation and competitive pricing.

Replacement & Compatibility FAQ
Q: Can I use a third-party SGCT module to replace the GU-D08?
A: Potentially, but it requires careful electrical parameter matching and gate-drive compatibility verification. We strongly recommend consulting a qualified drive engineer before substituting.
Q: Is the FGC800B-130DS the same as 80173-109-01?
A: These are cross-reference identifiers for the same physical module — FGC800B-130DS is the thyristor manufacturer’s code, while 80173-109-01 is the Rockwell Automation assembly part number.
Q: Do you offer tested-used or refurbished units?
A: Yes. We stock new, refurbished, and tested-used units. All refurbished units are functionally tested and documented. Please specify your condition preference when requesting a quote.
Q: What warranty do you provide?
A: New OEM units carry the manufacturer’s standard warranty. Refurbished and tested-used units carry a Konmask 90-day functional warranty. Extended warranty options are available — contact us for details.
Q: Can you help identify the correct replacement if my part number is different?
A: Yes. Send us your nameplate data, system model, and any visible part numbers and our technical team will cross-reference and recommend the correct module.
