System Compatibility
- Primary System: NIKON SR-EX3
- Subsystem: LBC-GX logic/control board slot
- Interface: Verify backplane connector and revision level (Rev. B confirmed for 400-0332-000B)
- Firmware: Must match system controller firmware version — consult NIKON service documentation or contact Konmask for guidance
Selection Guide
Use the following criteria to select the correct PCB assembly for your SR-EX3 system:
- Step 1 — Identify your system revision: Check the SR-EX3 system nameplate or service manual for the platform revision code.
- Step 2 — Match the board designation: Confirm LBC-GX slot designation in your system’s board layout diagram.
- Step 3 — Verify part number suffix: 400-0332-000B indicates Revision B. Do not substitute Revision A boards without engineering approval.
- Step 4 — Check firmware version: Request the firmware version label from your current board before ordering a replacement.
- Step 5 — Contact Konmask: Share your system serial number and current part number — we will confirm exact compatibility before shipment.

Replacement & Compatibility FAQ
Q: Can I use 4S017-489-2 and 400-0332-000B interchangeably?
A: These are cross-referenced OEM part numbers for the same assembly. Confirm the revision suffix (000B) matches your system’s requirement.
Q: Is a refurbished board as reliable as a new OEM board?
A: Refurbished boards from Konmask are fully tested and functionally equivalent. We recommend new OEM for critical production environments and refurbished for backup/spare inventory.
Q: Do you provide installation support?
A: We provide part-level technical documentation. For system-level installation, consult a certified NIKON field service engineer.
Q: What is the return policy?
A: We offer a 30-day return window for unused items in original packaging. Tested/refurbished items carry a 90-day functional warranty.
Q: Can you source other NIKON SR-EX3 spare parts?
A: Yes. Contact us with your full BOM or part list — we specialize in hard-to-find semiconductor equipment spares.
