ET103A32-Z Toggle Switch SPST 3A 125V Equivalent & Substitute Parts

Part Overview

The ET103A32-Z is a panel-mount toggle switch manufactured by Nidec Components Corporation, configured as a single-pole single-throw (SPST) switch rated for 3A at 125V AC. This component features a standard round actuator with 17.00mm length and solder lug termination, designed for on-off switching applications. The product is classified as obsolete, making identification of equivalent substitute parts essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ET103A32-Z is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPST)
• Electrical ratings (3A AC, 125V AC)
• Mounting interface (Panel Mount, M12 x 1 bushing thread, 12.50mm circular cutout)
• Mechanical interface (Standard round actuator, 17.00mm length, solder lug termination)
• Functional classification (On-Off switching)
• Compliance certifications (ROHS3 Compliant)

The ET103A12-Z qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and mounting requirements. Both parts belong to the ET series and maintain the same functional and physical characteristics necessary for direct replacement in legacy applications.

Parameter Comparison

Engineering Selection Recommendations

The ET103A12-Z provides direct functional and mechanical equivalence to the ET103A32-Z. Both components maintain identical electrical performance specifications, panel mounting interfaces, and actuator geometry. Selection between these parts should be based on availability and packaging format. The ET103A32-Z is available in original packaging (1076 units in stock), while the ET103A12-Z is available in bulk packaging (999 units in stock). Both parts carry ROHS3 compliance certification and are suitable for applications requiring ROHS-compliant component sourcing. The obsolete product status of both parts indicates that long-term availability may be limited; inventory verification is recommended prior to procurement for production applications.

Frequently Asked Questions (FAQ)

Q: Can the ET103A12-Z replace the ET103A32-Z in existing applications?

A: Yes. The ET103A12-Z is a direct substitute. Both parts share identical electrical ratings (3A, 125V AC), circuit configuration (SPST), mechanical dimensions (17.00mm actuator length, 12.50mm panel cutout), and termination style (solder lug). Panel mounting and functional performance are equivalent.

Q: What is the difference between ET103A32-Z and ET103A12-Z?

A: The primary difference is packaging format. The ET103A32-Z is supplied in original manufacturer packaging, while the ET103A12-Z is supplied in bulk packaging. All electrical, mechanical, and functional specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the ET103A32-Z and ET103A12-Z are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Why are both parts listed as obsolete?

A: Obsolete product status indicates that these components are no longer in active production by the manufacturer. Current inventory represents remaining stock. For applications requiring long-term component availability, alternative current-production toggle switches with equivalent electrical and mechanical specifications should be evaluated.

Q: What are the critical parameters for substitution?

A: Substitution requires equivalence in circuit configuration (SPST), electrical ratings (3A AC, 125V AC), mounting interface (M12 x 1 panel mount, 12.50mm cutout), actuator geometry (standard round, 17.00mm length), and termination style (solder lug). Deviation in any of these parameters disqualifies a part as a direct substitute.
