Key Parameters

Substitute Part Grouping Explanation

The ET420N12-Z qualifies as a direct substitute for the ET415N12-Z based on the following substitution criteria:

Matching Parameters (Substitution Basis):

• Manufacturer: Nidec Components Corporation (same manufacturer)
• Series: ET (identical series)
• Circuit Configuration: 4PDT (identical circuit)
• Switch Function: On-On (identical function)
• Voltage Rating: 125V AC (identical voltage)
• Mounting Type: Panel Mount (identical mounting)
• Actuator Type: Standard Round (identical actuator)
• Actuator Length: 17.50mm (identical length)
• Termination Style: Solder Lug (identical termination)
• Panel Cutout Dimensions: Circular - 12.50mm Dia (identical cutout)
• Bushing Thread: M12 x 1 (identical thread)
• Electrical Life: 20,000 Cycles (identical cycle rating)
• RoHS Status: ROHS3 Compliant (identical compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical MSL)

Differing Parameter (Upgrade Consideration):

• Current Rating: ET420N12-Z is rated for 20A AC versus ET415N12-Z at 15A AC

The ET420N12-Z represents a higher current capacity variant within the same product family, maintaining all mechanical, electrical, and environmental specifications while providing increased current handling capability.

Parameter Comparison

Engineering Selection Recommendations

The ET420N12-Z is suitable as a substitute for the ET415N12-Z in applications where the original component is no longer available due to obsolete product status. Both components maintain ROHS3 compliance and identical mechanical specifications, ensuring direct panel mount compatibility without modification to existing designs.

The ET420N12-Z provides increased current capacity (20A versus 15A), which represents a design margin improvement. This higher current rating does not introduce incompatibility with the original 15A specification and may be selected where component availability is the primary constraint.

Both parts are manufactured by Nidec Components Corporation within the ET series, share identical electrical life ratings, and maintain equivalent environmental classifications. Selection between these parts should be based on current application requirements and component availability.

Frequently Asked Questions (FAQ)

Q: Can the ET420N12-Z directly replace the ET415N12-Z in existing designs?

A: Yes. The ET420N12-Z maintains identical mechanical dimensions, panel cutout specifications, bushing thread size, actuator configuration, and termination style. No physical modifications to the panel or circuit board are required for substitution.

Q: What is the significance of the current rating difference?

A: The ET420N12-Z is rated for 20A AC compared to the ET415N12-Z at 15A AC. This represents a higher current capacity within the same physical package. Applications originally designed for 15A operation will function within the ET420N12-Z specifications without derating.

Q: Are both parts RoHS compliant?

A: Yes. Both the ET415N12-Z and ET420N12-Z are ROHS3 compliant and carry identical moisture sensitivity level classification of 1 (Unlimited).

Q: What is the electrical life expectancy for both switches?

A: Both components are rated for 20,000 electrical cycles, providing equivalent operational longevity.

Q: Are there packaging differences between these parts?

A: The ET415N12-Z is supplied in standard packaging, while the ET420N12-Z is available in bulk packaging. This distinction affects procurement and inventory management but does not impact component functionality or specifications.

Q: Can the ET420N12-Z be used in applications requiring exactly 15A operation?

A: Yes. The ET420N12-Z is rated for 20A maximum, which encompasses 15A operation. The component will function correctly in circuits designed for 15A current draw.
