C98043-A7125 is a SINAMICS DCM connector-board designation providing customer terminals and communication interfaces for CUD assemblies.
Siemens documentation identifies C98043-A7125 as the connector board fitted to SINAMICS DCM Control Unit (CUD) assemblies. It carries customer-terminal and communication interfaces used by the drive control system.
The official spare-parts table lists the complete board variant as C98043-A7125-L1 with Siemens order number 6RY18030GA00. Because the supplied identifier omits the -L1 suffix, procurement must verify the installed board label, converter MLFB and serial number before substitution.

Supports restoration of documented customer-terminal and communication connections on SINAMICS DCM control-unit assemblies.
Applicable to maintenance programs that identify the connector-board marking and confirm the complete orderable spare reference.
Provides a reference point for checking terminal allocation, serial links, PROFIBUS interfaces and parallel-drive connections before retrofit work.
Siemens official manuals confirm the C98043-A7125 connector-board designation, but no current official lifecycle category was verified for this identifier. No Active, Product Cancellation, Obsolete or Discontinued status is inferred.
Siemens documentation identifies it as the connector-board designation used with SINAMICS DCM Control Unit assemblies.
Not in the official spare-parts table. Siemens lists C98043-A7125-L1 with order number 6RY18030GA00.
Official diagrams show X177, X170, PROFIBUS X126/X166, parallel interface X165, RS485 X178 and RS232 X179.
No. Confirm the full board suffix, unit MLFB, serial number, CUD version and connector arrangement.
Provide clear board photographs, complete unit order number, serial number, CUD type, connector layout and required quantity.
Contact Stockoems for board-label verification, compatibility review, warranty terms and worldwide delivery coordination.
Structured support for identifying, checking and coordinating a C98043-A7125 SINAMICS DCM connector-board requirement.
Our team reviews nameplate photographs, printed board references and the associated Siemens converter information before sourcing coordination.
Visible connector areas, terminal blocks, board edges, mounting points and identification labels can be checked against supplied evidence.
ESD-conscious packing, protective cushioning, shipment documents and worldwide delivery options are coordinated for industrial spares.
Confirm whether the physical marking is C98043-A7125 or the complete board variant C98043-A7125-L1, and whether Siemens spare 6RY18030GA00 is the required orderable item.
Provide the converter MLFB, serial number, CUD arrangement, board revision and clear installed-location photographs for a procurement review.
Check the required X177, X170, X126, X165, X166, X178 and X179 terminal or communication interfaces against the machine documentation.
| Review Point | Recommended Evidence | Procurement Purpose |
|---|---|---|
| Identity | Full board label and all suffixes | Avoid confusion between a board designation and an orderable spare number |
| Configuration | Converter MLFB, CUD type and wiring diagram | Assess system fit before replacement planning |
| Condition | Front, rear, connector and edge photographs | Support visible-condition inspection |
| Delivery | Destination, urgency and packing requirements | Coordinate freight and protective packing |
