Key Parameters

Substitute Part Grouping Explanation

The MY4-GS-R DC48 qualifies as a direct substitute for the MY4-GS DC48 based on the following critical parameters:

• Contact Configuration: Both parts maintain identical 4PDT (4 Form C) contact form
• Coil Voltage: Both operate at 48VDC
• Relay Type: Both are general purpose relays with non-latching coil type
• Switching Voltage Rating: Both support 250VAC and 220VDC maximum switching voltage
• Series Compatibility: Both belong to the Omron MY series
• Compliance: The substitute part maintains RoHS3 compliance, exceeding the original RoHS requirement

The primary distinction is the mounting configuration: the MY4-GS-R DC48 is socketable with plug-in quick connect termination, whereas the original MY4-GS DC48 mounting type is not specified. The substitute part is currently in active production status, ensuring long-term availability.

Engineering Selection Recommendations

The MY4-GS-R DC48 is the appropriate substitute for the obsolete MY4-GS DC48 based on the following factors:

• Product Continuity: The substitute part is in active production status, ensuring availability for current and future procurement cycles
• Compliance Enhancement: The MY4-GS-R DC48 meets ROHS3 compliance, providing improved environmental and regulatory alignment compared to the original RoHS Compliant designation
• Functional Equivalence: All critical electrical parameters—contact form, coil voltage, switching voltage, and coil type—are identical between the original and substitute parts
• Series Consistency: Both parts maintain the same Omron MY series designation, ensuring compatibility with existing relay base sockets and control circuit designs

Selection of the MY4-GS-R DC48 eliminates obsolescence risk while maintaining full functional compatibility with applications originally designed for the MY4-GS DC48.

Frequently Asked Questions (FAQ)

Q: Can the MY4-GS-R DC48 be used as a direct replacement for the MY4-GS DC48?

A: Yes. Both relays share identical contact form (4PDT), coil voltage (48VDC), switching voltage rating (250VAC, 220VDC max), and coil type (non-latching). The MY4-GS-R DC48 is the manufacturer-recommended substitute.

Q: What is the primary difference between these two relay models?

A: The MY4-GS-R DC48 features socketable mounting with plug-in quick connect termination (0.110" / 2.8mm), whereas the original MY4-GS DC48 mounting type is not specified. The substitute part also provides documented electrical specifications including coil current (18.8 mA), contact rating (6 A), and operating temperature range (-55°C ~ 70°C).

Q: Why is the original MY4-GS DC48 listed as obsolete?

A: The MY4-GS DC48 has reached end-of-life status in Omron's product portfolio. The MY4-GS-R DC48 represents the active production alternative within the same series.

Q: Are there any compliance differences between the two parts?

A: The MY4-GS DC48 carries RoHS Compliant status, while the MY4-GS-R DC48 meets the more stringent ROHS3 Compliant standard. Both parts satisfy environmental and regulatory requirements for industrial applications.

Q: What termination style does the substitute part use?

A: The MY4-GS-R DC48 uses plug-in quick connect termination with 0.110" (2.8mm) connectors, enabling rapid installation and removal from relay bases.

Q: Is the contact material specified for the original part?

A: The original MY4-GS DC48 contact material is not specified in the available documentation. The MY4-GS-R DC48 uses silver (Ag) contact material, which is standard for general purpose relays in this voltage and current class.
