Omron MY4N-D2-GS DC48 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY4N-D2-GS DC48 is a general purpose relay with 4PDT (4 Form C) contact configuration and 48VDC coil voltage. This socketable relay is designed for applications requiring 3A contact rating at switching voltages up to 250VAC or 125VDC. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MY4N-D2-GS DC48 is determined by the following critical parameters:

Primary Substitution Criteria:

• Coil voltage: 48VDC (exact match required)
• Contact form: 4PDT (4 Form C) configuration
• Mounting type: Socketable
• Termination style: Plug In connection
• Coil type: Non Latching
• Relay type: General Purpose

Secondary Compatibility Parameters:

• Contact rating current: 3A minimum
• Switching voltage: 250VAC, 125VDC minimum
• Must operate and release voltages: 38.4 VDC / 4.8 VDC
• Operating temperature range: -55°C ~ 60°C minimum
• Coil current: 17.6 mA nominal
• Coil resistance: 2.73 kOhms nominal

Two substitute parts are identified based on these parameters. The first represents a manufacturer-recommended upgrade with enhanced specifications. The second provides a parametric equivalent maintaining identical electrical and mechanical characteristics.

Engineering Selection Recommendations

MY4ZN-D2-DC48(S) - Parametric Equivalent Selection

The MY4ZN-D2-DC48(S) maintains identical electrical and mechanical specifications to the obsolete MY4N-D2-GS DC48, including 3A contact rating, 14-pin plug-in termination, and -55°C ~ 60°C operating temperature range. This part is currently active and RoHS compliant, making it the direct replacement for applications requiring exact specification matching. The MY4ZN series provides continuity for existing designs without modification.

MY4N-D2-GS-R DC48 - Manufacturer-Recommended Upgrade

The MY4N-D2-GS-R DC48 is the manufacturer-recommended substitute, offering enhanced specifications including 6A contact rating and extended switching voltage capability (220VDC maximum). This part features an additional mechanical indicator and uses quick-connect termination (0.110" / 2.8mm) instead of the 14-pin plug-in style. The operating temperature range extends to 70°C. This option is suitable for applications where higher current capacity or extended temperature operation is beneficial, provided the termination style change is accommodated in the circuit design.

Both substitutes are manufactured by Omron Automation and Safety and maintain the core 48VDC coil voltage, 4PDT contact configuration, and socketable mounting required for functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the MY4N-D2-GS-R DC48 directly replace the MY4N-D2-GS DC48 in existing circuits?

A: The MY4N-D2-GS-R DC48 is electrically compatible for coil voltage, contact form, and switching characteristics. However, the termination style differs: the substitute uses quick-connect 0.110" (2.8mm) terminals instead of the 14-pin plug-in configuration. Socket compatibility must be verified before installation.

Q: What is the difference between the two substitute parts?

A: The MY4ZN-D2-DC48(S) is a parametric equivalent maintaining all original specifications including 3A contact rating and 14-pin termination. The MY4N-D2-GS-R DC48 is an upgraded variant with 6A contact rating, extended temperature range (-40°C ~ 70°C), and quick-connect termination. Selection depends on whether the application requires exact specification matching or can benefit from enhanced capabilities.

Q: Are both substitute parts RoHS compliant?

A: The MY4ZN-D2-DC48(S) is explicitly RoHS compliant. RoHS compliance status for the MY4N-D2-GS-R DC48 is not specified in available documentation.

Q: Can I use the MY4N-D2-GS-R DC48 in applications requiring the -55°C lower temperature limit?

A: The MY4N-D2-GS-R DC48 has a minimum operating temperature of -40°C, which does not meet the -55°C requirement of the original part. For applications requiring -55°C operation, the MY4ZN-D2-DC48(S) is the appropriate selection.

Q: What is the impact of the different coil resistance values?

A: The MY4N-D2-GS DC48 and MY4ZN-D2-DC48(S) both have 2.73 kOhms coil resistance. The MY4N-D2-GS-R DC48 has 2.56 kOhms, resulting in slightly higher coil current (18.8 mA vs. 17.6 mA). This difference is within normal operating margins for 48VDC coil circuits but should be verified in power supply designs with tight current budgets.

Q: Does the higher 6A contact rating of the MY4N-D2-GS-R DC48 affect compatibility?

A: Higher contact rating provides additional capacity margin and does not negatively impact applications designed for 3A operation. The part remains suitable for circuits rated at or below 3A.
