Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MY2N-D2-GS DC48 is determined by the following critical parameters:

Core Compatibility Requirements:

• Coil voltage: 48VDC (must operate and release within specified voltage windows: 38.4 VDC minimum operate, 4.8 VDC maximum release)
• Contact form: DPDT (2 Form C) configuration
• Mounting type: Socketable with plug-in termination
• Series: Omron MY series relay platform
• Contact material: Silver (Ag)
• Coil type: Non-latching

Allowable Substitution Variance:

• Contact rating current: Equal to or greater than 5A
• Switching voltage: Equal to or greater than 250VAC, 125VDC
• Operating temperature range: Must encompass or exceed -55°C ~ 60°C
• Coil current: Minor variance acceptable (within 10% tolerance typical for relay coils)
• Operate/Release time: Consistent at 20 ms
• Features: May include additional features (mechanical indicator, quick connect options) without affecting core functionality

The MY2N-D2-GS-R DC48 qualifies as a direct substitute based on these parameters while offering enhanced specifications in contact rating and switching voltage capability.

Parameter Comparison

Engineering Selection Recommendations

The MY2N-D2-GS-R DC48 is the manufacturer-recommended substitute for the obsolete MY2N-D2-GS DC48. Selection is based on the following engineering criteria:

Product Status Consideration: The original part is classified as obsolete, while the substitute is actively manufactured by Omron Automation and Safety. This ensures long-term availability and supply chain continuity for new designs and ongoing system support.

Electrical Compatibility: The substitute maintains identical coil voltage (48VDC), contact form (DPDT), and critical operating parameters (must-operate and must-release voltages, operate/release times). The higher contact rating (10A versus 5A) and extended switching voltage capability (220VDC maximum versus 125VDC) provide enhanced margin without introducing incompatibility.

Mechanical Compatibility: Both parts share socketable mounting with plug-in termination. The substitute offers an additional quick-connect termination option (0.110" / 2.8mm), which does not preclude use of standard plug-in connections.

Operational Margin: The substitute's extended upper operating temperature limit (70°C versus 60°C) provides additional thermal margin for applications operating near the original specification boundary. The lower temperature limit (-40°C versus -55°C) represents a minor reduction applicable only to extreme cold environments.

Compliance: Both parts are RoHS compliant, supporting regulatory requirements for electronic component selection.

Frequently Asked Questions (FAQ)

Q: Can the MY2N-D2-GS-R DC48 be used as a direct replacement for the MY2N-D2-GS DC48 in existing applications?

A: Yes. The substitute maintains identical coil voltage, contact configuration, and critical operating parameters. The higher contact rating and switching voltage provide additional capability without affecting compatibility with existing circuit designs or mechanical mounting.

Q: What is the significance of the higher 10A contact rating on the substitute versus the original 5A rating?

A: The substitute's 10A rating indicates it can safely switch higher currents through its contacts. In applications where the original 5A rating was sufficient, the substitute operates with additional margin. Applications requiring currents between 5A and 10A benefit from the substitute's enhanced capability.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: The substitute's range (-40°C ~ 70°C) encompasses the original range (-55°C ~ 60°C) in the upper portion. Applications operating between -40°C and 60°C experience no difference. Applications requiring operation below -40°C must retain the original part. Applications operating between 60°C and 70°C benefit from the substitute's extended capability.

Q: Are there packaging differences between the main part and substitute?

A: The original part packaging is listed as "-" (not specified). The substitute is supplied in bulk packaging. Both parts use identical socketable mounting and plug-in termination, ensuring mechanical interchangeability.

Q: What does the additional "Quick Connect - 0.110" (2.8mm)" termination option on the substitute mean?

A: The substitute offers an alternative termination method in addition to standard plug-in connections. This provides design flexibility for new applications while maintaining full compatibility with existing plug-in socket installations.

Q: Is the MY2N-D2-GS-R DC48 the only available substitute for this obsolete relay?

A: Based on the provided manufacturer data, the MY2N-D2-GS-R DC48 is identified as the manufacturer-recommended substitute. Other relays within the Omron MY series may offer functional equivalence, but substitution eligibility requires verification against the core compatibility parameters: 48VDC coil voltage, DPDT contact form, socketable mounting, and plug-in termination.

Q: What is the difference in coil current between the two parts (17.6 mA versus 18.8 mA)?

A: The 1.2 mA difference represents approximately 6.8% variance, which is within normal tolerance for relay coil specifications. This minor difference does not affect circuit design or power supply requirements for typical applications.

Q: Can the substitute be used in applications requiring the original -55°C lower temperature limit?

A: No. The substitute's minimum operating temperature is -40°C. Applications requiring operation below -40°C must use the original MY2N-D2-GS DC48 or identify alternative relays with equivalent low-temperature capability.
