Omron MY2 DC100/110 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2 DC100/110 is a general purpose relay with DPDT (2 Form C) contact configuration designed for 110VDC coil operation. This socketable relay is rated for 5A switching current and features non-latching operation with silver contact material. The product is currently obsolete, making identification of compatible substitute parts essential for system maintenance and component replacement in legacy applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Omron MY2 DC100/110 is determined by the following critical parameters:

• Coil voltage must be 110VDC 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 ensure mechanical fit in existing relay sockets
• Termination style must support plug-in connection for direct replacement
• Contact rating must meet or exceed 5A to handle the same load requirements
• Maximum switching voltage must support the application's voltage levels

The PT270110 from TE Connectivity Potter & Brumfield Relays meets these core substitution criteria while offering enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity PT270110 serves as a direct substitute for the obsolete Omron MY2 DC100/110 based on matching coil voltage, contact configuration, and socketable mounting requirements. The PT270110 is an active product with ROHS3 compliance and REACH unaffected status, providing regulatory continuity for new designs and system updates.

The PT270110 offers performance improvements over the original part: higher contact current rating (12A versus 5A), faster switching times (15ms operate, 10ms release versus 20ms each), and lower coil current draw (6.8mA versus 9.6mA). The substitute part maintains compatibility with existing relay sockets and control circuits while providing enhanced reliability through silver-nickel contact material and active product support.

Frequently Asked Questions (FAQ)

Q: Can the PT270110 be used as a direct replacement in existing systems using the MY2 DC100/110?

A: Yes. Both relays share identical coil voltage (110VDC), contact form (DPDT), socketable mounting, and plug-in termination. The PT270110 is mechanically and electrically compatible for direct socket replacement.

Q: What are the key differences between these two relays?

A: The PT270110 provides higher contact current capacity (12A versus 5A), faster switching response times, lower coil current consumption, and active product status with modern compliance certifications. Contact material differs: silver versus silver-nickel.

Q: Does the higher contact rating of the PT270110 affect compatibility?

A: No. A higher contact rating is a performance enhancement that does not compromise compatibility. The PT270110 can safely handle applications rated for the original 5A specification.

Q: Are there temperature range considerations for substitution?

A: The PT270110 operates from -40°C to 70°C, compared to the MY2 DC100/110 range of -55°C to 70°C. For applications requiring operation below -40°C, the original specification must be verified.

Q: What is the significance of the RoHS3 compliance on the PT270110?

A: RoHS3 compliance indicates the substitute part meets current environmental and hazardous substance restrictions, supporting regulatory requirements for new installations and system updates.

Q: Are both relays available in the same packaging format?

A: Both relays use socketable plug-in termination. The PT270110 supports both standard plug-in and quick-connect 0.110" (2.8mm) termination options, providing installation flexibility.
