HG2-AC24V-F Equivalent & Substitute Parts

Part Overview

The Panasonic Electric Works HG2-AC24V-F is a general purpose relay with DPDT (2 Form C) contact configuration rated for 20A at 24VAC. This socketable relay is designed for applications requiring reliable switching of AC circuits. The product is currently obsolete, making equivalent substitute parts necessary for system maintenance, repair, and new design implementations where compatible alternatives are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HG2-AC24V-F is determined by the following critical parameters:

• Coil Voltage: Must be 24VAC to match control circuit requirements
• Contact Form: Must be DPDT (2 Form C) to maintain switching functionality
• Contact Rating: Must support minimum 20A to handle load requirements
• Termination Style: Must use Quick Connect - 0.250" (6.3mm) for mechanical compatibility
• Coil Type: Must be Non Latching to match operational behavior

The Omron Automation and Safety MJN2C-E-AC24 meets all critical substitution criteria. While mounting type differs (chassis mount versus socketable), the electrical characteristics and termination interface remain compatible for equivalent circuit operation.

Parameter Comparison

Engineering Selection Recommendations

The MJN2C-E-AC24 is the qualified substitute for the obsolete HG2-AC24V-F. Selection is based on:

• Electrical Equivalence: Both relays provide identical coil voltage (24VAC), contact configuration (DPDT), and current rating (20A)
• Mechanical Compatibility: Both utilize Quick Connect - 0.250" (6.3mm) termination, ensuring direct interface compatibility
• Product Status: The MJN2C-E-AC24 is active and available, addressing the obsolescence of the original part
• Compliance: The MJN2C-E-AC24 carries RoHS Compliant status, meeting modern regulatory requirements
• Performance Margin: The substitute provides higher switching voltage capability (600VAC maximum versus 250VAC nominal) and extended operating temperature range (-45°C to 60°C versus -50°C to 40°C), offering improved operational flexibility

The primary design difference is mounting type (chassis mount versus socketable). System integration must account for this mechanical variation during installation.

Frequently Asked Questions (FAQ)

Q: Can the MJN2C-E-AC24 directly replace the HG2-AC24V-F in existing circuits?

A: Yes, from an electrical standpoint. Both relays share identical coil voltage, contact configuration, current rating, and termination interface. Mechanical mounting differences require evaluation based on your specific installation requirements.

Q: What is the significance of the different coil current values (150 mA vs. 70.8 mA)?

A: The MJN2C-E-AC24 requires less coil current to operate, which may reduce power consumption in control circuits. Both values are within acceptable operating parameters for 24VAC control systems.

Q: Are there compatibility concerns with the different contact materials?

A: Both contact materials (Silver Tin Oxide and Silver Alloy) are standard for general purpose relays. Material selection does not affect substitution compatibility for equivalent switching applications.

Q: How does the operating temperature range difference affect substitution?

A: The MJN2C-E-AC24 supports a wider operating range (-45°C to 60°C versus -50°C to 40°C). For applications within the original HG2-AC24V-F temperature specification, both relays are suitable. For extended temperature applications, the substitute provides additional capability.

Q: What mounting considerations are necessary?

A: The HG2-AC24V-F is socketable (plug-in base mount), while the MJN2C-E-AC24 is chassis mount. Your installation must accommodate the chassis mount configuration, which may require different mechanical fastening or panel integration.

Q: Is the MJN2C-E-AC24 RoHS compliant?

A: Yes, the MJN2C-E-AC24 is RoHS Compliant, meeting current environmental and regulatory standards.
