GE IC694MDL660
The Real-World Problem It Solves
This is the RoHS-compliant version of the IC694MDL660 series, released in January 2016. Same function, same wiring, same software configuration—but manufactured with lead-free solder and compliant components to meet EU RoHS directives. If your facility requires RoHS-compliant equipment for regulatory or export reasons, this is the revision you specify.
Where you’ll typically find it:
- New installations in EU markets requiring RoHS compliance
- Export projects to regions with hazardous substance restrictions
- Facilities with sustainability mandates specifying lead-free electronics
Bottom line: Form-fit-function identical to IC694MDL660-BC, but with RoHS-compliant manufacturing. Order this if your procurement spec says “RoHS” or you’re shipping to the EU.
Hardware Architecture & Under-the-Hood Logic
The IC694MDL660-CC has the exact same architecture as previous revisions. The difference is entirely in the manufacturing process and component materials:
RoHS conversion changes:
- Lead-free solder: All PCB solder joints use RoHS-compliant alloys instead of traditional lead-based solder.
- Component materials: Any components containing restricted substances (lead, mercury, cadmium, hexavalent chromium, PBB, PBDE) were replaced with compliant alternatives.
- No firmware changes: The module firmware and diagnostic behavior are identical to IC694MDL660-BC.
- No performance changes: Response times, isolation ratings, power consumption, and input characteristics are unchanged.

Field Service Pitfalls: What Rookies Get Wrong
Assuming RoHS Means “Improved” or “Different Specs”RoHS compliance is a manufacturing and materials standard, not a performance upgrade. The -CC revision doesn’t have faster response times, better isolation, or new features. It’s the same module built with different solder and component materials.
- Field Rule: Treat IC694MDL660-CC as a direct, one-for-one replacement for any earlier IC694MDL660 revision. No configuration changes, no firmware updates, no performance differences.
Ignoring RoHS Requirements in ProcurementIf you’re specifying equipment for an EU installation or a project with RoHS requirements, ordering an older revision (like -BC) can cause procurement delays or compliance failures. The supplier may ship the older revision if you don’t explicitly specify -CC.
- Field Rule: For RoHS-mandated projects, explicitly specify -CC in your purchase order. Don’t assume the supplier will automatically ship the latest revision.
Mixing Revisions in the Same SystemThere’s no technical reason you can’t mix -CC with older revisions in the same rack—they’re functionally identical. But some quality management systems require uniformity for traceability. If your site has such a requirement, you may need to replace all modules of a type to match the newest revision.
- Quick Fix: Document which revision is installed where. If your QMS requires revision uniformity, plan a phased replacement to standardize on -CC during scheduled maintenance windows.
Terminal Block Still Not IncludedLike every other revision, -CC ships without a terminal block. The RoHS conversion doesn’t change this.
- Field Rule: Order IC694TBB032 or IC694TBS032 separately. This catches everyone eventually.
