Key Parameters

Substitute Part Grouping Explanation

Substitution of the ET325E12-Z is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (3PDT)
• Switch function (On-Off-On)
• Voltage rating (125V AC)
• Mounting type (Panel Mount)
• Actuator type (Standard Round)
• Actuator length (17.00mm)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 12.50mm Dia)
• Bushing thread (M12 x 1)

Allowable Variation:

• Current rating: The ET330E12-Z is rated for 30A AC, which exceeds the 25A requirement of the ET325E12-Z. Higher current ratings are acceptable substitutes when the application does not exceed the original 25A specification.

The ET330E12-Z qualifies as a direct substitute because it maintains all mandatory parameters while providing enhanced current capacity, making it suitable for applications requiring the ET325E12-Z.

Parameter Comparison

Engineering Selection Recommendations

Both the ET325E12-Z and ET330E12-Z are classified as obsolete products from Nidec Components Corporation. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency in legacy system applications.

The ET330E12-Z serves as a functional equivalent with enhanced current capacity. Selection between these parts depends on application current requirements. For circuits designed to operate at or below 25A, either part is suitable. For applications requiring higher current margins or future capacity expansion within the 125V AC specification, the ET330E12-Z provides additional headroom.

Mechanical and electrical interface compatibility is assured across both parts, including panel mounting dimensions, bushing thread specifications, and solder lug termination.

Frequently Asked Questions (FAQ)

Q: Can the ET330E12-Z replace the ET325E12-Z in all applications?

A: Yes, the ET330E12-Z is a direct substitute for the ET325E12-Z. The 30A rating of the ET330E12-Z exceeds the 25A specification of the ET325E12-Z, making it compatible with any circuit designed for the original part. All mechanical and electrical interface parameters are identical.

Q: Are there any panel cutout or mounting modifications required when substituting the ET330E12-Z?

A: No modifications are required. Both parts feature identical panel cutout dimensions (circular 12.50mm diameter) and bushing thread specifications (M12 x 1), ensuring direct mechanical compatibility without panel rework.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the ET325E12-Z and ET330E12-Z are ROHS3 compliant with identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent environmental and regulatory performance.

Q: What is the significance of the higher current rating on the ET330E12-Z?

A: The ET330E12-Z is rated for 30A AC compared to the 25A AC rating of the ET325E12-Z. This higher rating provides additional current capacity and operational margin. Applications operating at or below 25A will function identically with either part.

Q: Are the electrical life specifications identical between these parts?

A: Yes. Both the ET325E12-Z and ET330E12-Z are rated for 20,000 electrical cycles, ensuring equivalent operational longevity in switching applications.
