Omron MY2-AC200/220 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY2-AC200/220 is a general purpose relay with DPDT (2 Form C) contact configuration and 220VAC coil voltage, rated for 5A switching current. This socketable relay is designed for applications requiring reliable switching of AC and DC loads at moderate current levels.

The MY2-AC200/220 is classified as obsolete. Identifying suitable substitute parts is necessary to maintain system functionality, ensure continued availability for maintenance and new designs, and support long-term product lifecycle management.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MY2-AC200/220 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Coil Voltage: 220VAC
• Contact Form: DPDT (2 Form C)
• Coil Type: Non Latching
• Contact Material: Silver (Ag)

Allowable Variation Parameters:

• Contact Rating (Current): May be equal or higher than 5A
• Switching Voltage: Must meet or exceed 250VAC, 125VDC
• Mounting Type: May differ (socketable to chassis mount acceptable for circuit redesign)
• Termination Style: May differ (plug-in to solder lug acceptable for circuit redesign)
• Operating Temperature Range: May be narrower or wider
• Coil Current: Minor variations acceptable within design tolerance
• Operate/Release Time: Minor variations acceptable within application requirements

The Omron MM2 AC200/(220) qualifies as a substitute based on matching all mandatory parameters while offering higher current rating (15A vs. 5A) and improved switching voltage capability (250VAC, 250VDC).

Parameter Comparison

Engineering Selection Recommendations

The MM2 AC200/(220) is an active product from Omron Automation and Safety and serves as the direct substitute for the obsolete MY2-AC200/220. Both relays share identical coil voltage (220VAC), contact configuration (DPDT), and operational voltage thresholds (176VAC must-operate, 66VAC must-release).

The MM2 AC200/(220) provides enhanced specifications: higher contact current rating (15A vs. 5A), extended DC switching capability (250VDC vs. 125VDC), and RoHS compliance. These improvements make it suitable for applications currently using the MY2-AC200/220 without functional degradation.

Design modifications are required for mounting and termination: the MM2 series uses chassis mount with solder lug termination, whereas the MY2 series uses socketable plug-in configuration. Circuit board layout and mechanical mounting must be adapted accordingly.

The narrower operating temperature range of the MM2 (-10°C ~ 55°C vs. -55°C ~ 70°C) must be evaluated for applications requiring extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can the MM2 AC200/(220) directly replace the MY2-AC200/220 without circuit modifications?

A: The MM2 AC200/(220) is electrically compatible with the MY2-AC200/220 for coil voltage, contact configuration, and switching characteristics. However, mounting type and termination style differ. Socketable plug-in connections must be replaced with chassis mount solder lug connections, requiring circuit board redesign.

Q: What is the significance of the higher current rating (15A vs. 5A) on the MM2 substitute?

A: The MM2 AC200/(220) supports higher switching current (15A) than the original MY2-AC200/220 (5A). This provides design margin and allows the relay to handle applications with increased current demands without exceeding contact ratings. Applications limited to 5A or less remain fully compatible.

Q: Are there temperature range limitations when substituting the MM2 for the MY2?

A: The MM2 AC200/(220) operates within -10°C ~ 55°C, compared to the MY2-AC200/220 range of -55°C ~ 70°C. Applications requiring operation below -10°C or above 55°C must evaluate whether the narrower range is acceptable for the intended environment.

Q: What does RoHS compliance on the MM2 mean for my application?

A: RoHS compliance on the MM2 AC200/(220) indicates restriction of hazardous substances in accordance with applicable regulations. This is beneficial for applications subject to environmental or regulatory requirements. The original MY2-AC200/220 RoHS status is not specified.

Q: How do coil resistance differences (12.95 kOhms vs. 1.54 kOhms) affect circuit design?

A: The significant difference in coil resistance affects coil current draw and power consumption. The MM2 AC200/(220) draws approximately 19.5 mA compared to 17 mA for the MY2-AC200/220. Circuit power supply and control electronics must be evaluated to ensure adequate current capacity for the substitute relay.

Q: Are the operate and release times (20ms vs. 25ms/30ms) critical for my application?

A: The MM2 AC200/(220) has slightly longer operate time (25ms vs. 20ms) and release time (30ms vs. 20ms). Applications with strict timing requirements must evaluate whether these differences affect system performance or safety-critical functions.
