Omron G2A-432A-D DC110 Equivalent & Substitute Parts

Part Overview

The Omron G2A-432A-D DC110 is a general purpose relay with 4PDT (4 Form C) contact configuration, rated for 500 mA at 110VDC coil voltage. This socketable relay is designed for applications requiring multiple independent switching circuits with reliable contact performance. The G2A series is classified as obsolete, making identification of suitable substitute parts essential for system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the G2A-432A-D DC110 is determined by the following critical parameters:

• Contact Configuration: 4PDT (4 Form C) contact form is mandatory for functional equivalence
• Mounting Interface: Socketable mounting type with plug-in termination ensures mechanical compatibility
• Coil Voltage Class: 110V coil voltage (DC or AC) maintains circuit compatibility
• Contact Rating: Minimum 500 mA current rating required for load switching capability
• Switching Voltage: Maximum 250VAC and 125VDC switching voltage capability
• Coil Type: Non-latching operation for standard relay control applications
• Diode Feature: Integrated diode for coil protection

The MY4Z-D DC100/110 series relay meets these substitution criteria through equivalent contact configuration, socketable mounting, compatible coil voltage specification, and superior contact rating capacity.

Engineering Selection Recommendations

The MY4Z-D DC100/110 relay is an active production substitute for the obsolete G2A-432A-D DC110. Selection of this substitute is supported by:

• Product Availability: Active manufacturing status ensures long-term supply and support
• Functional Equivalence: Identical 4PDT contact configuration and socketable mounting interface
• Enhanced Capability: Contact rating of 3 A exceeds the 500 mA requirement, providing design margin
• Environmental Compliance: RoHS compliant status meets current regulatory requirements
• Electrical Compatibility: Coil resistance and current specifications are functionally equivalent

The primary design consideration is the coil voltage difference: the substitute operates on 110VAC rather than 110VDC. Circuit implementation must accommodate this voltage type change, including appropriate power supply and control circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the MY4Z-D DC100/110 be used as a direct drop-in replacement for the G2A-432A-D DC110?

A: Mechanical compatibility is confirmed through identical socketable mounting and plug-in termination. Electrical compatibility requires verification of socket pin configuration and coil voltage supply. The 110VAC coil voltage differs from the original 110VDC specification and requires circuit modification.

Q: What is the significance of the contact rating difference between 500 mA and 3 A?

A: The MY4Z-D DC100/110 contact rating of 3 A exceeds the G2A-432A-D DC110 requirement of 500 mA. This provides additional design margin and allows the substitute to handle higher load currents without derating. Applications limited to 500 mA loads are fully supported.

Q: Are there pin configuration differences between these relays?

A: The G2A-432A-D DC110 uses plug-in termination, while the MY4Z-D DC100/110 specifies 14-pin plug-in termination. Socket compatibility must be verified before installation to ensure proper electrical connection.

Q: How does the operating temperature range affect substitution?

A: The MY4Z-D DC100/110 operating temperature range of -55°C to 60°C exceeds the G2A-432A-D DC110 range of -10°C to 40°C. Applications within the original temperature specification are fully supported. Extended temperature operation is possible with the substitute.

Q: What is the impact of the coil voltage type change from DC to AC?

A: The substitute requires 110VAC coil supply instead of 110VDC. This necessitates modification of the control circuit power supply and may affect relay response characteristics. Coil current and resistance specifications remain functionally equivalent.

Q: Is the MY4Z-D DC100/110 RoHS compliant?

A: Yes, the MY4Z-D DC100/110 is RoHS compliant. The original G2A-432A-D DC110 RoHS status is not specified. This compliance status is relevant for applications subject to environmental regulations.
