Compatible Replacement & Equivalent Models
The following models are commonly evaluated as functional replacements or equivalents for the AGDR-72C. Always verify electrical and mechanical compatibility before substitution:
- ABB AGDR-71C — Earlier revision; verify firmware and connector pinout compatibility
- ABB AGDR-73C — Later revision with enhanced protection; drop-in compatible in most ACS800 platforms
- ABB AGDR-76C — Higher current rating variant; suitable for uprated drive configurations
- ABB NGDR-02C / NGDR-03C — Next-generation driver series; requires adapter harness in legacy chassis
- Third-party equivalents — Available from qualified OEM-grade suppliers; must match isolation voltage, gate resistance, and PWM signal interface
Note: Konmask supplies only verified, tested units. Contact us for cross-reference confirmation before ordering.

System Compatibility
The AGDR-72C is primarily designed for use within the following ABB drive families. Confirm your drive’s hardware revision and IGBT module type before ordering:
- ABB ACS800-01 / -04 / -07 / -11 / -17 / -31 / -37
- ABB ACS880-01 / -07 / -17 / -37 (with compatible IGBT stack)
- ABB ACSM1 (motion control drives, select power ranges)
- ABB DCS880 DC drive platforms (select configurations)
If your drive model is not listed, contact Konmask with your full drive nameplate data for a compatibility assessment.
Selection Guide
Use the following criteria to determine whether the AGDR-72C is the correct part for your application:
- Step 1 — Identify your drive model: Confirm the ABB drive series and power rating from the nameplate
- Step 2 — Locate the existing driver board: Check the part number printed on the PCB silkscreen or label (AGDR-72C / 68436788A)
- Step 3 — Verify IGBT module type: Confirm the IGBT module brand and current rating in your drive stack
- Step 4 — Check revision compatibility: Compare hardware revision codes if upgrading from AGDR-71C or earlier
- Step 5 — Confirm quantity: Multi-phase drives may require 2–6 driver boards per unit; specify phase count when ordering
- Step 6 — Contact Konmask: Share your drive model, serial number, and existing part number for final confirmation

Replacement & Compatibility FAQ
Q: Can the AGDR-72C replace the AGDR-71C directly?
A: In most ACS800 platforms, yes — the AGDR-72C is a revised version of the AGDR-71C with the same connector layout. However, verify the firmware version of your drive’s control board before swapping.
Q: Is the AGDR-73C a drop-in replacement for the AGDR-72C?
A: Generally yes for ACS800 series drives. The AGDR-73C adds enhanced desaturation protection. Confirm with ABB documentation or contact Konmask for your specific drive revision.
Q: How many AGDR-72C boards does my drive require?
A: This depends on the drive topology. A 3-phase 2-level inverter typically uses 6 driver boards (one per IGBT). Provide your drive model for an exact count.
Q: Do you supply refurbished units?
A: Yes. All refurbished units are fully tested, cleaned, and carry a 90-day warranty. Test reports are available on request.
Q: Can I use a third-party equivalent driver board?
A: Third-party equivalents exist but must precisely match the gate resistance, isolation voltage, and PWM interface of the original. Konmask can advise on verified third-party options if OEM stock is unavailable.
Q: What is the lead time for out-of-stock units?
A: Typically 5–15 business days for sourced units. Expedited sourcing is available for critical downtime situations — contact us directly.
