Key Parameters

Substitute Part Grouping Explanation

Substitution of the MY4-GS AC200/220 is determined by the following critical parameters that must remain constant or be compatible:

• Coil Voltage: 220VAC (exact match required for direct circuit compatibility)
• Contact Form: 4PDT (4 Form C) configuration (functional requirement for switching four independent circuits)
• Mounting Type: Socketable (mechanical compatibility with existing relay bases)
• Termination Style: Plug In (electrical connection compatibility)
• Operating Temperature Range: -55°C ~ 70°C (environmental operating conditions)
• Contact Material: Silver (Ag) (electrical performance and reliability characteristics)

The MY4-GS-R AC200/220 qualifies as a substitute because it maintains all critical parameters while offering enhanced contact rating capability (6 A versus 3 A) and extended termination options.

Engineering Selection Recommendations

The MY4-GS-R AC200/220 is the direct substitute for the obsolete MY4-GS AC200/220. Selection is based on the following engineering criteria:

• Product Status: The main part is obsolete; the substitute is active and currently in production, ensuring long-term availability and supply chain continuity.
• Compliance: Both parts are RoHS Compliant, meeting environmental and regulatory requirements.
• Functional Equivalence: Identical coil voltage, contact configuration, switching characteristics, and operating temperature range ensure drop-in compatibility in existing circuit designs.
• Enhanced Capability: The substitute offers increased contact rating (6 A versus 3 A), providing additional margin for applications operating at or near the 3 A limit of the original part.
• Termination Compatibility: The substitute maintains the standard Plug In termination while adding Quick Connect option, preserving compatibility with existing relay bases.

Frequently Asked Questions (FAQ)

Q: Can the MY4-GS-R AC200/220 be used as a direct replacement for the MY4-GS AC200/220?

A: Yes. Both relays share identical coil voltage (220VAC), contact form (4PDT), mounting type (socketable), and operating characteristics. The substitute is mechanically and electrically compatible with existing installations.

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

A: The MY4-GS-R AC200/220 has a higher contact rating of 6 A compared to the 3 A rating of the original part. This provides increased switching capacity for higher current applications. The substitute also offers an additional Quick Connect termination option.

Q: Are there any compatibility concerns with relay bases or sockets?

A: No. Both relays use socketable mounting with Plug In termination, ensuring compatibility with standard MY series relay bases. The additional Quick Connect option on the substitute does not affect compatibility with existing Plug In sockets.

Q: Does the substitute meet the same environmental and regulatory standards?

A: Yes. Both parts are RoHS Compliant and operate across the same temperature range (-55°C ~ 70°C), meeting equivalent environmental and regulatory requirements.

Q: What is the inventory status of these parts?

A: The MY4-GS AC200/220 (obsolete) has 765 pieces in stock. The MY4-GS-R AC200/220 (active) has 778 pieces in stock, providing reliable availability for new orders and replacements.
