Parameter Comparison

Engineering Selection Recommendations

The RY211012 is the direct substitute for the obsolete RY210012. Both components share identical electrical specifications, mechanical configuration, and functional performance characteristics.

Product Status Consideration: The RY210012 is obsolete with no active manufacturing. The RY211012 maintains active product status with current manufacturing and availability, ensuring long-term supply chain continuity.

Compliance and Certification: The RY211012 carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic components. These certifications support deployment in applications subject to environmental and hazardous substance restrictions.

Contact Material Difference: The RY210012 uses Silver Cadmium Oxide (AgCdO) contact material, while the RY211012 uses Silver Nickel (AgNi). Both materials maintain the specified 8A contact rating and 400VAC switching voltage. The Silver Nickel composition in the RY211012 aligns with modern manufacturing practices and regulatory compliance frameworks.

Electrical and Mechanical Equivalence: All critical parameters—coil voltage, contact form, current rating, switching voltage, coil current, coil resistance, operating temperature range, mounting type, termination style, and seal rating—are identical between the two components. Direct substitution is supported without circuit modification or application redesign.
