Compatible Replacement & Equivalent Models
The following models are functionally compatible or serve as direct replacements depending on firmware revision and system generation:
- TDK TAS-CPU REV.3.xx series (earlier firmware — confirm compatibility)
- TDK TAS-CPU REV.4.00 / REV.4.05 (same hardware platform, firmware upgrade may be required)
- TDK 653B-21800 (predecessor part number — verify connector pinout)
- TDK 0100-20156 (alternate BOM reference for same assembly)
- Equivalent third-party FOUP Load Port CPU boards (E84-compliant, 24 VDC, same I/O mapping) — contact Konmask for cross-reference
Always verify PCB revision, firmware version, and connector layout before substitution. Konmask engineers can assist with compatibility confirmation.

Replacement & Compatibility FAQ
Q: Can TAS-CPU REV.4.10 replace REV.3.xx directly?
A: Hardware connectors are typically compatible, but firmware differences may require host-side E84 timing adjustment. Contact us for a compatibility assessment.
Q: Is 653B-21801 the same as 0100-20157?
A: Yes — these are dual part numbers for the same assembly (TDK internal BOM vs. customer-facing part number).
Q: Do you offer a warranty on refurbished units?
A: Yes, 90-day functional warranty on all tested refurbished units. New OEM units carry standard manufacturer warranty.
Q: Can you supply the TAS-MAIN backplane separately?
A: Yes. Contact us with your system configuration for backplane and sub-board availability.
Q: What if my part number is not listed?
A: Send us your PCB photo or equipment model number — our team will identify and source the correct module.
