HG2-AC220V Equivalent & Substitute Parts

Part Overview

The HG2-AC220V is a general purpose relay manufactured by Panasonic Electric Works, featuring a DPDT (2 Form C) contact configuration with a 220VAC coil and 20A contact rating. This socketable relay is designed for standard industrial switching applications. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and new design implementations where this relay specification remains applicable.

Substitute Part Grouping Explanation

Substitute parts for the HG2-AC220V are identified based on the following critical parameters that must align for functional equivalence:

• Coil Voltage: 220VAC (exact match required)
• Contact Form: DPDT (2 Form C) configuration (exact match required)
• Mounting Type: Socketable (exact match required)
• Coil Type: Non Latching (exact match required)
• Must Operate Voltage: 176 VAC minimum (ensures coil activation within specified range)
• Must Release Voltage: 66 VAC maximum (ensures coil de-energization within specified range)

The MM2P-AC200-220 from Omron Automation and Safety meets all critical substitution criteria. While the contact rating differs (7.5A vs. 20A), this represents a derating that maintains functional compatibility for applications within the substitute's current capacity. The socketable mounting and octal pin termination provide mechanical and electrical compatibility with standard relay bases designed for this form factor.

Engineering Selection Recommendations

The MM2P-AC200-220 is an active product from Omron Automation and Safety and represents the primary substitute for the obsolete HG2-AC220V. Selection of this substitute is appropriate when:

• The application load current does not exceed 7.5A (the contact rating of the substitute)
• DPDT switching functionality is required
• 220VAC coil operation is specified
• Socketable mounting with octal pin termination is compatible with existing relay bases
• RoHS compliance is required (MM2P-AC200-220 is RoHS Compliant)

The substitute maintains equivalent coil activation and release voltage thresholds, ensuring predictable operation within the specified control voltage range. Timing differences (operate and release times) should be evaluated against application requirements, as the substitute exhibits slightly longer response times (25ms operate, 30ms release vs. 15ms for the original).

Frequently Asked Questions (FAQ)

Q: Can the MM2P-AC200-220 directly replace the HG2-AC220V in all applications?

A: The MM2P-AC200-220 is mechanically and electrically compatible for socketable mounting applications. However, the contact rating is reduced from 20A to 7.5A. Direct replacement is suitable only for applications where the load current does not exceed 7.5A. If the original application requires the full 20A contact rating, the substitute is not appropriate.

Q: What is the significance of the different termination styles?

A: The HG2-AC220V uses Quick Connect - 0.250" (6.3mm) termination, while the MM2P-AC200-220 uses 8 Pin (Octal) termination. Both are plug-in socketable styles compatible with standard relay bases. The specific base type must match the termination style of the relay selected. Existing installations using HG2-AC220V bases may require base replacement or adapter consideration.

Q: Are there differences in operating temperature ranges?

A: Yes. The HG2-AC220V operates from -50°C to 40°C, while the MM2P-AC200-220 operates from -10°C to 55°C. For applications requiring operation below -10°C, the substitute may not be suitable. For applications within the -10°C to 40°C overlap range, both relays are compatible.

Q: What does "Non Latching" coil type mean?

A: Non Latching indicates that the relay contacts return to their de-energized state when coil power is removed. This is standard for general purpose relays. Both the original and substitute share this characteristic.

Q: Is the MM2P-AC200-220 RoHS compliant?

A: Yes, the MM2P-AC200-220 is RoHS Compliant. The HG2-AC220V status is listed as REACH Unaffected. For applications requiring RoHS compliance, the substitute meets this requirement.

Q: How do the coil currents compare?

A: The HG2-AC220V draws 16.4 mA, while the MM2P-AC200-220 draws 17.5 mA. Both values are comparable and represent minimal difference in control circuit design considerations.
