Replacement & Compatibility FAQ
Q: Can I replace 2MBI100NC-120 with 2MBI100NC-120-01?
A: Yes. The -01 revision is a direct drop-in replacement with improved switching characteristics. No circuit changes required.
Q: Is the Infineon FZ100R12KE3 a direct replacement?
A: Electrically equivalent in ratings, but the package footprint differs. A custom heatsink adapter is required. Not recommended for field repair without engineering review.
Q: How do I identify a counterfeit 2MBI100NC-120?
A: Check the laser-etched date code and lot number on the module top. Genuine units have consistent font depth and no ink printing. Request a COC from your supplier. Konmask provides full traceability documentation.
Q: What gate drive voltage does this module require?
A: ±15 V gate drive is standard. Gate resistor (Rg) values per Fuji application note AN-2MBI-NC: 10–22 Ω for turn-on, 10–22 Ω for turn-off.
Q: Can this module be used in a two-level inverter?
A: The 2MBI100NC-120 is optimized for NPC three-level topologies. While electrically usable in two-level circuits, the NPC clamp diode structure adds unnecessary complexity. Use 2MBI100U4B-120 for standard two-level applications.
