Siemens C98043-A7109-L100 Coated Power Interface Board
The board-level identifier associated with the Siemens 6RY1803-0CM20 coated power-interface spare.
Product Profile
C98043-A7109-L100 is the board identifier for a coated Siemens power-interface assembly. The related Siemens commercial article number is used as a second check during procurement and service.
The board should remain tied to its host drive, hardware revision and connector arrangement. A visually similar C98043 board with another suffix must not be treated as equivalent.

- Comparison of a removed power-interface assembly during spare selection.
- Revision-controlled maintenance of legacy converter cabinets.
FAQ
Which commercial article should be compared with C98043-A7109-L100?
Use Siemens article 6RY1803-0CM20 as the cross-reference and confirm both codes on the installed assembly.
Can another C98043 suffix replace C98043-A7109-L100?
No automatic interchangeability should be assumed because suffixes can identify different functions, revisions or coated executions.
What visual evidence is needed for C98043-A7109-L100?
Provide both sides of the board, every label, connector population, mounting points and its location inside the host drive.
Why must the coated execution of C98043-A7109-L100 be preserved?
A change in coating status can affect the documented environmental and service configuration, so it requires explicit review.
What precautions apply before changing C98043-A7109-L100?
Isolate the converter, wait for stored energy to discharge, verify safe voltage and use ESD controls.
What checks follow a C98043-A7109-L100 installation?
Confirm seating, connector positions, insulation and clearances, then run drive diagnostics and a controlled functional test.
