The RY211048 meets all specified electrical, mechanical, and functional parameters and qualifies as a direct substitute for the obsolete RY210048.

Parameter Comparison

Engineering Selection Recommendations

The RY211048 is the direct substitute for the obsolete RY210048. Both components share identical electrical specifications, mechanical form factors, and functional performance characteristics across all critical parameters.

Product Status Advantage: The RY211048 carries an active product status with current manufacturing support, ensuring long-term availability and supply chain continuity compared to the discontinued RY210048.

Regulatory Compliance: The RY211048 is certified as ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements. This compliance status supports applications requiring adherence to modern electronic component standards.

Contact Material Difference: The RY211048 employs Silver Nickel (AgNi) contact material, whereas the RY210048 uses Silver Cadmium Oxide (AgCdO). Both materials are suitable for the specified 8A contact rating and 400VAC switching voltage. The AgNi contact material in the RY211048 represents current manufacturing practice and eliminates cadmium-based materials from the design.

Inventory Availability: The RY211048 is available in higher inventory quantities (2316 pieces) compared to the RY210048 (928 pieces), supporting both immediate procurement and long-term stock planning.

Frequently Asked Questions (FAQ)

Q: Can the RY211048 directly replace the RY210048 in existing circuit designs?

A: Yes. The RY211048 meets all electrical, mechanical, and functional specifications of the RY210048. Both components feature identical coil voltage (48VDC), contact configuration (SPDT), current rating (8A), timing characteristics (9ms operate, 5ms release), and operating temperature range (-40°C to 70°C). Direct substitution is supported without circuit modification.

Q: What is the significance of the contact material difference between AgCdO and AgNi?

A: Both Silver Cadmium Oxide (AgCdO) and Silver Nickel (AgNi) contact materials are rated for the specified 8A contact current and 400VAC switching voltage. The AgNi material in the RY211048 represents current manufacturing standards and eliminates cadmium-based compositions. This change does not affect electrical performance or switching capability within the specified operating parameters.

Q: Why is the RY210048 listed as obsolete?

A: The RY210048 has been discontinued by the manufacturer. The RY211048 is the active replacement product, offering identical performance with current manufacturing support and regulatory compliance certifications.

Q: Are there packaging differences between the RY210048 and RY211048?

A: The RY210048 is specified with standard packaging, while the RY211048 is supplied in bulk packaging. Both components maintain identical through-hole mounting form factors and PC pin termination styles, ensuring mechanical compatibility in PCB applications.

Q: Does the RY211048 meet current environmental regulations?

A: Yes. The RY211048 is ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components in industrial and commercial applications.

Q: Are the coil resistance and electrical operating parameters identical?

A: Yes. Both the RY210048 and RY211048 share identical coil resistance (9.4 kOhms), coil current (5.1 mA), must operate voltage (33.6 VDC), and must release voltage (4.8 VDC). Electrical circuit behavior is equivalent.
