Key Parameters

Substitute Part Grouping Explanation

Substitution for the MY4IN-GS AC48 is determined by the following critical parameters:

• Coil voltage specification (48VAC)
• Contact configuration (4PDT / 4 Form C)
• Mounting type compatibility (Socketable)
• Electrical ratings (contact current, switching voltage)
• Coil characteristics (non-latching operation)

The MY4IN-GS-R AC48 qualifies as a direct substitute based on matching these core parameters while maintaining active product status within the same manufacturer's product line.

Parameter Comparison

Engineering Selection Recommendations

The MY4IN-GS-R AC48 is the designated manufacturer-recommended substitute for the obsolete MY4IN-GS AC48. Both components share the same base product number (MY4IN) and identical coil voltage specification (48VAC), ensuring functional compatibility in existing circuit designs.

The transition from MY4IN-GS AC48 to MY4IN-GS-R AC48 is supported by the active product status of the substitute part, providing long-term availability and supply chain continuity. The MY4IN-GS-R AC48 maintains socketable mounting compatibility and identical contact configuration, enabling direct replacement in applications currently utilizing the obsolete variant.
