Key Parameters

Substitute Part Grouping Explanation

The ET103V12-Z qualifies as a direct substitute for the ET103V32-Z based on identical electrical and mechanical parameters. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 3A (AC)
• Voltage rating: 125V AC
• Mounting type: Panel Mount
• Actuator type: Standard Round
• Actuator length: 17.00mm
• Panel cutout dimensions: Circular - 12.50mm Dia
• Bushing thread: M12 x 1
• Termination style: Solder Lug
• Electrical life: 10,000 Cycles
• RoHS compliance: ROHS3 Compliant

The ET103V12-Z maintains all functional and dimensional specifications required for direct substitution in applications originally designed for the ET103V32-Z.

Parameter Comparison

Engineering Selection Recommendations

Both the ET103V32-Z and ET103V12-Z are obsolete products from Nidec Components Corporation. The ET103V12-Z is a valid substitute based on complete parameter equivalence across all electrical, mechanical, and compliance specifications. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental compatibility in legacy system applications.

Selection between these parts should be based on current inventory availability and packaging requirements. The ET103V32-Z is packaged in standard format, while the ET103V12-Z is available in bulk packaging. For applications requiring immediate component sourcing, availability should be the primary selection criterion.

Frequently Asked Questions (FAQ)

Q: Can the ET103V12-Z replace the ET103V32-Z in existing designs?

A: Yes. The ET103V12-Z is a direct substitute with identical electrical ratings (3A, 125V AC), circuit configuration (SPDT), mechanical dimensions (17.00mm actuator, M12 x 1 bushing), and termination style (solder lug). No design modifications are required.

Q: What is the difference between ET103V32-Z and ET103V12-Z?

A: The primary difference is packaging. The ET103V32-Z is supplied in standard packaging, while the ET103V12-Z is supplied in bulk packaging. All functional and dimensional specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the ET103V32-Z and ET103V12-Z are ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: What does the obsolete status mean for these parts?

A: Obsolete status indicates these parts are no longer in active production by Nidec Components Corporation. Availability is limited to existing inventory. Sourcing should prioritize available stock from authorized distributors.

Q: Can these switches be used in AC applications only?

A: The voltage rating specified is 125V AC. Application in DC circuits requires verification against DC switching specifications, which are not provided in the available parameters.

Q: What is the panel cutout requirement for installation?

A: Both parts require a circular panel cutout of 12.50mm diameter with M12 x 1 bushing thread for secure panel mount installation.
