Key Parameters

Substitute Part Grouping Explanation

Substitution of the ET325D12-Z is determined by the following critical parameters that must remain constant or be compatible:

• Circuit Configuration: 3PDT topology must be maintained
• Switch Function: On-On operation required
• Voltage Rating: 125V AC minimum
• Mounting Interface: Panel mount with M12 x 1 bushing thread and 12.50mm circular cutout
• Actuator Geometry: Standard round type with 17.00mm length
• Termination: Solder lug connection
• Compliance: ROHS3 compliance and MSL 1 rating

The ET330D12-Z qualifies as a direct substitute based on identical mechanical and electrical interface parameters. The primary distinction is the increased current rating of 30A AC, which provides enhanced capacity while maintaining all other specifications.

Parameter Comparison

Engineering Selection Recommendations

The ET330D12-Z serves as a direct functional equivalent to the ET325D12-Z for applications requiring 3PDT panel-mount toggle switches with 125V AC operation. Both components maintain identical mechanical interfaces, ensuring drop-in compatibility in existing panel cutouts and mounting configurations.

Selection between these parts depends on application current requirements. The ET330D12-Z provides 30A capacity compared to the ET325D12-Z at 25A, offering increased current handling capability within the same physical envelope. Both components satisfy ROHS3 compliance requirements and MSL 1 moisture sensitivity specifications.

The obsolete status of both parts indicates that long-term availability through standard distribution channels may be limited. Component selection should account for current inventory levels and application lifecycle requirements.

Frequently Asked Questions (FAQ)

Q: Can ET330D12-Z replace ET325D12-Z in existing designs? A: Yes. The ET330D12-Z is mechanically and electrically compatible. Panel cutout dimensions, bushing thread specifications, actuator geometry, and termination style are identical. The increased 30A current rating does not affect compatibility.

Q: What is the primary difference between these parts? A: The current rating differs. ET325D12-Z is rated for 25A AC, while ET330D12-Z is rated for 30A AC. All other electrical and mechanical parameters remain identical.

Q: Are both parts ROHS3 compliant? A: Yes. Both ET325D12-Z and ET330D12-Z carry ROHS3 compliance certification.

Q: What does the obsolete product status mean for procurement? A: Obsolete status indicates these components are no longer in active production. Availability is limited to existing inventory. Procurement planning should account for potential supply constraints.

Q: Are the panel mounting interfaces identical? A: Yes. Both parts feature M12 x 1 bushing thread, 12.50mm circular panel cutout diameter, and panel mount configuration, ensuring identical installation requirements.

Q: Do both parts have the same electrical life rating? A: Yes. Both components are rated for 20,000 electrical cycles.
