ET115E-Z Toggle Switch SPDT 15A 125V Equivalent & Substitute Parts

Part Overview

The ET115E-Z is a panel-mount toggle switch manufactured by Nidec Components Corporation, configured as a Single Pole Double Throw (SPDT) switch with On-Off-On functionality. Rated for 15A at 125V AC, this component features a standard round actuator with quick-connect termination. The ET115E-Z is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where this series is no longer available.

Substitute Part Grouping Explanation

The S3F toggle switch from NKK Switches qualifies as a functional substitute for the ET115E-Z based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Off-On
• AC current rating: 15A
• AC voltage rating: 125V
• Mounting type: Panel Mount
• Actuator type: Standard Round
• Termination style: Quick Connect - 0.250" (6.3mm)
• Panel cutout dimensions: Circular - 12.50mm Dia
• Bushing thread: M12 x 1
• RoHS compliance: ROHS3 Compliant

The S3F maintains electrical and mechanical compatibility within the specified application envelope. Minor variations in actuator length (17.50mm vs 17.00mm) and electrical life rating (25,000 vs 30,000 cycles) do not preclude substitution in standard panel-mount applications.

Parameter Comparison

Engineering Selection Recommendations

The S3F from NKK Switches is the designated substitute for the obsolete ET115E-Z. Selection of the S3F is supported by:

• Active product status with current manufacturing availability
• Full ROHS3 compliance matching the original specification
• Identical electrical ratings and circuit configuration
• Compatible mechanical interface (panel cutout, bushing thread, termination)
• Established supply chain with documented inventory

The S3F is suitable for direct replacement in applications where the ET115E-Z is no longer procurable. The minor increase in actuator length (0.50mm) and reduction in electrical life rating (5,000 cycles) do not impact compatibility in standard panel-mount switching applications operating within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can the S3F directly replace the ET115E-Z in existing designs?

A: Yes. The S3F maintains identical electrical ratings (15A, 125V AC), circuit configuration (SPDT), and mechanical interface specifications (panel cutout, bushing thread, termination style). The component can be installed without modification to the panel assembly or electrical connections.

Q: What is the significance of the actuator length difference?

A: The S3F actuator is 0.50mm longer (17.50mm vs 17.00mm). This difference is within typical mechanical tolerances for panel-mount toggle switches and does not affect operational compatibility or user interface feel in standard applications.

Q: How do the electrical life ratings compare?

A: The ET115E-Z is rated for 30,000 cycles while the S3F is rated for 25,000 cycles. Both ratings exceed typical requirements for general-purpose switching applications. The difference reflects different manufacturing specifications and does not preclude substitution.

Q: Are there any compliance differences between the two parts?

A: Both components are ROHS3 compliant. The S3F carries additional REACH Unaffected status. No compliance barriers exist for substitution.

Q: What packaging is available for the S3F?

A: The S3F is supplied in bulk packaging. Verify packaging requirements against procurement specifications for your application.
