Substitute Part Grouping Explanation

Substitution of the MY2N-GS AC48 is determined by the following critical parameters that must remain consistent:

• Coil Voltage: 48VAC (exact match required)
• Contact Form: DPDT (2 Form C) configuration
• Coil Type: Non Latching
• Mounting Type: Socketable
• Coil Current: 21.1 mA (matching drive requirements)
• Coil Resistance: 788 Ohms
• Operating Temperature Range: -40°C ~ 70°C
• Contact Material: Silver (Ag)
• Must Operate Voltage: 38.4 VAC
• Must Release Voltage: 14.4 VAC

The MY2N-GS-R AC48 qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters. The primary difference is an increased contact rating (10A versus 5A), which represents an enhancement in switching capacity while preserving all other functional characteristics.

Engineering Selection Recommendations

The MY2N-GS-R AC48 is the qualified substitute for the obsolete MY2N-GS AC48. Selection is supported by the following factors:

Product Status: The MY2N-GS-R AC48 maintains active product status with Omron, ensuring ongoing availability and supply chain continuity compared to the obsolete original part.

Compliance: Both parts maintain RoHS compliance, satisfying regulatory requirements for electronic component procurement.

Electrical Compatibility: All critical electrical parameters—coil voltage, contact form, coil current, resistance, and switching thresholds—are identical between the main part and substitute. This ensures direct functional equivalence in existing circuit designs without modification.

Mechanical Compatibility: Both relays feature socketable mounting with plug-in termination, enabling direct physical replacement in existing socket installations. The substitute offers additional quick-connect termination options, providing installation flexibility without compromising the standard plug-in interface.

Performance Enhancement: The substitute part provides increased contact rating (10A versus 5A), representing a performance upgrade that maintains backward compatibility while supporting higher switching loads.

Frequently Asked Questions (FAQ)

Q: Can the MY2N-GS-R AC48 be used as a direct replacement for the MY2N-GS AC48?

A: Yes. The MY2N-GS-R AC48 is a direct substitute. All critical electrical parameters—coil voltage, contact configuration, coil current, and switching characteristics—are identical. The substitute is physically compatible with existing socketable installations and electrically compatible with existing circuit designs.

Q: What is the primary difference between these two relays?

A: The contact rating differs: the original part is rated for 5A, while the substitute is rated for 10A. This represents an enhancement in switching capacity. All other parameters remain unchanged.

Q: Are there any termination differences I should be aware of?

A: The MY2N-GS AC48 features standard plug-in termination. The MY2N-GS-R AC48 maintains plug-in termination and adds quick-connect 0.110" (2.8mm) termination as an option. Existing installations using standard plug-in sockets require no modification.

Q: Does the substitute part maintain the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 70°C.

Q: Are both parts RoHS compliant?

A: Yes. Both the MY2N-GS AC48 and MY2N-GS-R AC48 are RoHS compliant.

Q: What is the coil voltage requirement for these relays?

A: Both relays require 48VAC coil voltage. The must-operate voltage is 38.4VAC and the must-release voltage is 14.4VAC.

Q: Can I use the MY2N-GS-R AC48 in applications originally designed for the 5A-rated MY2N-GS AC48?

A: Yes. The 10A rating of the substitute part is a performance upgrade that maintains full backward compatibility. Applications designed for 5A operation will function identically with the substitute part.
