Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete MY4-GS AC24 is determined by strict equivalence across the following critical parameters:

• Coil voltage: 24VAC (exact match required)
• Contact form: 4PDT (4 Form C) configuration (exact match required)
• Coil type: Non Latching (exact match required)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In compatible (exact match required)
• Operating temperature range: -55°C ~ 70°C (exact match required)
• Contact material: Silver (Ag) (exact match required)
• Coil resistance: 180 Ohms (exact match required)
• Coil current: 46 mA (exact match required)

The MY4-GS-R AC24 meets all critical substitution criteria. This part maintains identical coil specifications, contact configuration, and operating characteristics while offering enhanced contact rating and updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MY4-GS-R AC24 is the direct substitute for the obsolete MY4-GS AC24. Both parts share identical coil specifications, contact configuration, and operating parameters. The MY4-GS-R AC24 offers the following advantages:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance provides enhanced environmental and regulatory alignment
• Contact rating increased to 6A provides additional margin for applications previously limited to 3A
• Backward compatible socketable mounting and plug-in termination enable direct replacement in existing designs
• Identical coil resistance and current draw maintain circuit compatibility without modification

Frequently Asked Questions (FAQ)

Q: Can the MY4-GS-R AC24 directly replace the MY4-GS AC24 in existing applications?

A: Yes. Both relays share identical coil voltage (24VAC), contact form (4PDT), coil current (46 mA), coil resistance (180 Ohms), operating temperature range (-55°C ~ 70°C), and termination style (Plug In). The socketable mounting type is identical, enabling direct socket replacement without circuit modification.

Q: What is the difference in contact rating between these parts?

A: The MY4-GS AC24 has a 3A contact rating, while the MY4-GS-R AC24 has a 6A contact rating. Both maintain the same maximum switching voltage (250VAC, 220VDC). The higher rating of the substitute part provides additional current capacity without affecting compatibility.

Q: Are there packaging differences between these parts?

A: The MY4-GS AC24 is listed with "-" packaging designation, while the MY4-GS-R AC24 is supplied in Bulk packaging. Both parts use identical socketable mounting and plug-in termination, ensuring mechanical and electrical compatibility.

Q: What compliance certifications apply to each part?

A: The MY4-GS AC24 carries RoHS Compliant certification. The MY4-GS-R AC24 carries ROHS3 Compliant certification and is REACH Unaffected. Both parts meet current environmental and regulatory requirements for their respective product statuses.

Q: Why is the MY4-GS AC24 classified as obsolete?

A: The MY4-GS AC24 is no longer in active production. The MY4-GS-R AC24 represents the current active equivalent, offering the same functional performance with updated compliance certifications and enhanced contact rating.
