Omron MY2-GS AC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-GS AC12 is a general purpose relay with DPDT (2 Form C) contact configuration and 12VAC coil voltage. This socketable relay is designed for applications requiring 5A contact rating at switching voltages up to 250VAC or 220VDC. The product is currently obsolete, making identification of suitable substitute components essential for system maintenance and new designs requiring equivalent functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2-GS AC12 is determined by the following critical parameters that must remain consistent:

Mandatory Matching Parameters:

• Coil voltage: 12VAC
• Contact form: DPDT (2 Form C)
• Coil type: Non Latching
• Mounting type: Socketable
• Coil current: 91 mA
• Coil resistance: 46 Ohms
• Must operate voltage: 9.6 VAC
• Must release voltage: 3.6 VAC
• Operating temperature range: -55°C ~ 70°C
• Contact material: Silver (Ag)

Allowable Variation Parameters:

• Contact rating (current): Equal to or greater than 5A
• Switching voltage: Equal to or greater than 250VAC, 220VDC
• Termination style: Plug In or compatible quick connect options
• Product status: Active preferred for ongoing availability

The MY2-GS-R AC12 qualifies as a direct substitute based on these criteria, with the additional benefit of active product status and enhanced contact rating capability.

Parameter Comparison

Engineering Selection Recommendations

The MY2-GS-R AC12 is the designated manufacturer substitute for the obsolete MY2-GS AC12. Both components maintain identical electrical and mechanical specifications for all critical parameters, ensuring functional equivalence in existing applications.

The MY2-GS-R AC12 offers the advantage of active product status, providing assured long-term availability and supply chain continuity. The enhanced contact rating of 10A compared to the original 5A provides additional design margin without requiring circuit modifications. The expanded termination options (Quick Connect - 0.110" in addition to standard Plug In) offer installation flexibility while maintaining backward compatibility with existing socketable bases.

Both components carry RoHS compliance certification, meeting environmental and regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the MY2-GS-R AC12 directly replace the MY2-GS AC12 in existing applications?

A: Yes. The MY2-GS-R AC12 maintains identical coil voltage, contact form, coil current, coil resistance, and operating characteristics. The socketable mounting type ensures mechanical compatibility with existing relay bases. The higher contact rating (10A vs 5A) does not affect compatibility and provides additional capacity margin.

Q: What is the significance of the higher 10A contact rating on the substitute part?

A: The MY2-GS-R AC12 contact rating of 10A exceeds the original 5A specification. This allows the substitute to handle higher switching currents without modification to the application circuit. Existing applications operating at or below 5A will function identically to the original component.

Q: Are there termination differences between these parts?

A: The MY2-GS AC12 uses standard Plug In termination. The MY2-GS-R AC12 supports both Plug In and Quick Connect - 0.110" (2.8mm) termination options. Existing installations using standard Plug In connections will operate without modification. The additional Quick Connect option provides installation flexibility for new designs.

Q: Does the product status change affect electrical performance?

A: No. Product status reflects manufacturing and supply availability, not electrical or mechanical performance. The active status of the MY2-GS-R AC12 ensures continued production and supply, whereas the obsolete status of the MY2-GS AC12 indicates discontinued manufacturing.

Q: Are both parts RoHS compliant?

A: Yes. Both the MY2-GS AC12 and MY2-GS-R AC12 carry RoHS compliance certification, meeting environmental and regulatory requirements for industrial applications.
