About Replacement Wiki
Replacement Wiki is the world's leading research database for industrial automation parts interchangeability and cross-references. Our mission is to help engineers, maintenance technicians, and procurement professionals around the globe quickly identify equivalent, compatible alternatives for discontinued, obsolete, or high-cost industrial hardware.
Our Mission
Industrial downtime is expensive. When a PLC, variable frequency drive, sensor, or servo motor goes end-of-life, sourcing a drop-in replacement can take days of cross-checking datasheets across vendors such as Siemens, ABB, Schneider Electric, Mitsubishi, Allen-Bradley, Omron, and Inovance. Replacement Wiki consolidates that knowledge into a single, structured, search-friendly database.
What We Provide
- Full technical specifications for thousands of industrial part numbers.
- Side-by-side cross-reference tables for equivalent and replacement models.
- Wiring diagrams, dimensional drawings, and terminal definitions.
- Common error codes and troubleshooting guidance.
- Direct links to manufacturer datasheets and product documentation.
Who We Serve
Our users include automation engineers, plant maintenance teams, OEM designers, distributors, and industrial procurement specialists in over 100 countries. Whether you are retrofitting a 20-year-old production line or sourcing cost-effective alternatives for new builds, Replacement Wiki accelerates the engineering selection process.
Editorial Standards
Every cross-reference entry is researched from publicly available manufacturer documentation. We continuously expand and verify our database, but data is provided as a reference only — final installation parameters must always be confirmed against the original manufacturer's specification sheets.
