Omron MY4I4 AC6 General Purpose Relay - Equivalent & Substitute Parts

Part Overview

The Omron MY4I4 AC6 is a general purpose relay featuring 4PDT (4 Form C) contact configuration with 3A contact rating and 6VAC coil voltage. This socketable relay is designed for general switching applications requiring reliable electromagnetic actuation. The MY4I4 AC6 is classified as obsolete, making identification of active equivalent and substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MY4I4 AC6 are identified based on strict electrical and mechanical parameter matching within the Omron MY series general purpose relay portfolio. The following parameters define substitution eligibility:

• Coil voltage: 6VAC (exact match required)
• Contact form: 4PDT (4 Form C) (exact match required)
• Contact rating: 3 A (exact match required)
• Switching voltage: 250VAC, 125VDC - Max (exact match required)
• Mounting type: Socketable (exact match required)
• Termination style: Plug In (exact match required)
• Coil type: Non Latching (exact match required)

Two substitute parts meet these criteria: MY4IN AC6 (S) and MY4I5 AC6. Both maintain full electrical and mechanical compatibility with the original MY4I4 AC6 specification.

Parameter Comparison

Engineering Selection Recommendations

Both MY4IN AC6 (S) and MY4I5 AC6 are active production parts suitable for replacing the obsolete MY4I4 AC6 in new designs and system upgrades.

MY4I5 AC6 provides the closest functional match to the original MY4I4 AC6, maintaining identical operating temperature range (-55°C ~ 70°C), coil resistance (12.2 Ohms), coil current (183 mA), and test button feature. This part is RoHS Compliant and carries active product status.

MY4IN AC6 (S) offers an alternative with RoHS Compliance and dual contact material options (Silver and Gold). The operating temperature range is reduced to -55°C ~ 60°C, which may require evaluation for applications requiring the full -55°C ~ 70°C range. This part is also in active production status.

Both substitute parts share identical electrical characteristics including coil voltage, contact configuration, contact rating, switching voltage, and timing specifications. Selection between these two options depends on specific application requirements regarding temperature range and contact material preferences.

Frequently Asked Questions (FAQ)

Q: Can MY4IN AC6 (S) replace MY4I4 AC6 in all applications?

A: MY4IN AC6 (S) is electrically and mechanically compatible with MY4I4 AC6 for applications operating within the -55°C ~ 60°C temperature range. Applications requiring operation at temperatures between 60°C and 70°C require MY4I5 AC6.

Q: What is the difference between MY4I5 AC6 and MY4IN AC6 (S)?

A: Both parts maintain identical electrical specifications and socketable mounting. MY4I5 AC6 supports the full -55°C ~ 70°C operating range and includes a test button feature. MY4IN AC6 (S) operates to -55°C ~ 60°C and offers dual contact materials (Silver and Gold). Both are RoHS Compliant.

Q: Are these substitutes pin-compatible with MY4I4 AC6?

A: Yes. Both MY4IN AC6 (S) and MY4I5 AC6 maintain identical socketable mounting and plug-in termination style, ensuring direct mechanical and electrical compatibility with existing MY4I4 AC6 socket installations.

Q: What is the significance of the "(S)" designation in MY4IN AC6 (S)?

A: The "(S)" designation indicates a specific variant within the MY4IN product line. Consult Omron documentation for variant-specific details.

Q: Are both substitute parts RoHS Compliant?

A: Yes. Both MY4IN AC6 (S) and MY4I5 AC6 are RoHS Compliant, meeting environmental regulatory requirements for new designs and procurement.

Q: What contact materials are available in these substitutes?

A: MY4I5 AC6 uses Silver (Ag) contact material. MY4IN AC6 (S) offers both Silver (Ag) and Gold (Au) contact options, providing flexibility for applications with specific contact material requirements.
