Omron MY2-GS DC12 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-GS DC12 is a general purpose relay with DPDT (2 Form C) contact configuration and 12VDC coil voltage. This socketable relay is designed for applications requiring 5A contact rating at 250VAC or 220VDC maximum switching voltage. The MY2-GS DC12 is classified as obsolete, making identification of suitable substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY2-GS DC12 is determined by the following critical parameters that must remain consistent:

Coil voltage (12VDC), contact form (DPDT), coil type (non-latching), mounting type (socketable), and termination style (plug-in compatible). The substitute part must maintain compatibility with the 12VDC coil supply and preserve the dual-pole, dual-throw switching architecture.

Contact rating represents the maximum current-carrying capacity. The substitute part may exceed the original 5A rating without creating incompatibility, as higher-rated contacts remain suitable for lower-current applications. Switching voltage, operating temperature range, and timing characteristics must align with or exceed the original specifications.

The MY2-GS-R DC12 qualifies as a direct substitute based on matching coil voltage, contact form, coil type, mounting type, and termination compatibility. The enhanced 10A contact rating provides increased current capacity while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MY2-GS-R DC12 is the recommended substitute for the obsolete MY2-GS DC12. Both parts are manufactured by Omron Automation and Safety and share identical coil voltage, contact configuration, and electrical timing characteristics. The MY2-GS-R DC12 carries active product status, ensuring ongoing availability and supply chain continuity.

The MY2-GS-R DC12 provides enhanced contact rating (10A versus 5A), expanding the range of compatible applications while maintaining full backward compatibility with existing 12VDC socketable relay installations. Both parts comply with RoHS requirements, with the substitute meeting the more recent ROHS3 standard. The substitute part includes quick-connect termination options in addition to standard plug-in compatibility, providing installation flexibility.

Frequently Asked Questions (FAQ)

Q: Can the MY2-GS-R DC12 directly replace the MY2-GS DC12 in existing installations?

A: Yes. Both relays share identical coil voltage (12VDC), contact form (DPDT), coil current (75 mA), timing characteristics (20 ms operate and release), and socketable mounting type. The substitute maintains full electrical and mechanical compatibility with the original part.

Q: What is the significance of the higher 10A contact rating on the MY2-GS-R DC12?

A: The MY2-GS-R DC12 supports higher current applications (up to 10A) compared to the original 5A rating. This enhanced capacity does not affect compatibility with lower-current applications; the relay remains suitable for any application originally designed for the 5A MY2-GS DC12.

Q: Are there termination differences between these parts?

A: The MY2-GS DC12 uses standard plug-in termination. The MY2-GS-R DC12 supports both plug-in and quick-connect (0.110" / 2.8mm) termination options. Existing plug-in socket installations remain fully compatible with the substitute part.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both parts comply with RoHS environmental standards. The MY2-GS-R DC12 meets the more recent ROHS3 specification, reflecting current regulatory requirements. This represents an advancement in compliance status with no negative impact on part functionality or compatibility.

Q: Why is the original MY2-GS DC12 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The MY2-GS-R DC12 represents the current active equivalent, providing identical functionality with enhanced specifications and ongoing manufacturer support.
