Omron MY2-GS AC220/240 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-GS AC220/240 is a general purpose relay with DPDT (2 Form C) contact configuration, rated for 5A at 240VAC. This socketable relay features a mechanical indicator and is designed for non-latching applications with 240VAC coil voltage. The MY2-GS AC220/240 is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations where this relay type is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2-GS AC220/240 is determined by the following critical parameters:

• Coil Voltage: Must be 240VAC to maintain direct compatibility with existing control circuits
• Contact Form: Must remain DPDT (2 Form C) to preserve switching functionality
• Mounting Type: Must be socketable to fit existing relay sockets
• Termination Style: Must support plug-in connection for direct socket compatibility
• Operating Temperature Range: Must encompass -55°C ~ 70°C minimum
• Contact Material: Silver (Ag) contact material ensures consistent switching performance
• Coil Type: Must be non-latching for equivalent operational behavior

The MY2-GS-R AC220/240 meets all these critical substitution criteria while offering enhanced contact rating and improved product status.

Engineering Selection Recommendations

The MY2-GS-R AC220/240 is the direct manufacturer-recommended substitute for the obsolete MY2-GS AC220/240. Both relays share identical coil voltage, contact form, switching characteristics, and operating parameters. The MY2-GS-R AC220/240 maintains active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. The increased contact rating of 10A in the substitute part provides additional design margin while maintaining full backward compatibility with existing socketable installations. The enhanced termination options in the MY2-GS-R AC220/240 (Quick Connect capability) offer installation flexibility without compromising the standard plug-in connection method.

Frequently Asked Questions (FAQ)

Q: Can the MY2-GS-R AC220/240 directly replace the MY2-GS AC220/240 in existing installations?

A: Yes. Both relays are socketable with identical plug-in termination, matching coil voltage (240VAC), identical contact form (DPDT), and equivalent operating characteristics. The MY2-GS-R AC220/240 fits directly into existing MY2-GS AC220/240 relay sockets.

Q: What is the significance of the higher 10A contact rating in the MY2-GS-R AC220/240 compared to the 5A rating of the original?

A: The MY2-GS-R AC220/240 provides a 10A contact rating versus the original 5A rating. This represents a design enhancement that maintains full compatibility while offering increased current-switching capacity. Applications originally designed for 5A operation remain fully supported.

Q: Are there packaging differences between these two relays?

A: The MY2-GS AC220/240 is packaged in standard format, while the MY2-GS-R AC220/240 is supplied in bulk packaging. Both maintain identical socketable form factors and plug-in termination for relay socket compatibility.

Q: What compliance certifications apply to the substitute part?

A: The MY2-GS-R AC220/240 carries ROHS3 compliance certification and is REACH unaffected, meeting current regulatory requirements for electronic components in industrial applications.

Q: Are the coil operating parameters identical between the two relays?

A: Yes. Both relays share identical coil voltage (240VAC), coil current (4.3 mA), coil resistance (15.92 kOhms), must-operate voltage (192 VAC), must-release voltage (72 VAC), and response times (20 ms operate and release). The relays are functionally equivalent in coil performance.
