Substitute Part Grouping Explanation

Substitution for the MY4IN-GS DC220 is based on maintaining functional equivalence within the MY series relay family. The primary substitute identified is the MY4IN-GS-R DC220, which shares the same base product number (MY4IN) and coil voltage specification (220VDC). This substitute maintains compatibility through identical electrical characteristics and contact configuration while offering active product status and enhanced availability.

The substitution logic is determined by the following critical parameters:

• Base product number alignment (MY4IN)
• Coil voltage specification (220VDC)
• Contact form and switching capability
• Termination style compatibility
• Electrical ratings (current, voltage, timing)

Parameter Comparison

Engineering Selection Recommendations

The MY4IN-GS-R DC220 is the manufacturer-recommended substitute for the obsolete MY4IN-GS DC220. Both components are manufactured by Omron Automation and Safety and share the same base product designation and coil voltage specification. The substitute part is currently in active production status with confirmed inventory availability (1048 pcs), ensuring supply chain continuity for applications requiring this relay type.

Selection of the MY4IN-GS-R DC220 is appropriate for direct replacement in existing designs and new implementations where the MY4IN series 220VDC relay is specified. The socketable mounting type and quick-connect termination style provide installation flexibility consistent with the original component family.

Frequently Asked Questions (FAQ)

Q: Can the MY4IN-GS-R DC220 directly replace the MY4IN-GS DC220?

A: Yes. Both components share the same base product number (MY4IN) and 220VDC coil voltage specification. The MY4IN-GS-R DC220 is the active production equivalent with identical functional characteristics.

Q: What is the primary difference between these two part numbers?

A: The MY4IN-GS DC220 is obsolete, while the MY4IN-GS-R DC220 is in active production. The suffix "-R" in the substitute part number indicates the current production variant within the MY4IN series.

Q: Are there any compatibility concerns with the termination style?

A: The MY4IN-GS-R DC220 features plug-in and quick-connect termination at 0.110" (2.8mm), which is standard for the MY4IN socketable relay family. Verify socket compatibility in your application before implementation.

Q: What is the coil current requirement for the substitute part?

A: The MY4IN-GS-R DC220 requires 3.6 mA coil current at 220VDC nominal operation, with a must-operate voltage of 176 VDC and must-release voltage of 22 VDC.

Q: Is the MY4IN-GS-R DC220 suitable for high-frequency switching applications?

A: The operate and release times are both 20 ms, which is appropriate for general purpose relay applications. Verify timing requirements against your specific application specifications.
