ET220P12-Z Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The ET220P12-Z is a toggle switch manufactured by Nidec Components Corporation, configured as a Double Pole Double Throw (DPDT) panel mount switch with On-Off-On functionality. This component is rated for 20A at 125V AC and features a standard round actuator with solder lug termination. The ET220P12-Z is currently classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ET220P12-Z is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-Off-On)
• Voltage rating (125V AC minimum)
• Mounting type (Panel Mount)
• Actuator type and length (Standard Round, 17.00mm)
• Termination style (Solder Lug)
• Panel cutout dimensions (Circular - 12.50mm Dia)
• Bushing thread specification (M12 x 1)
• RoHS compliance status (ROHS3 Compliant)

The ET225P12-Z qualifies as a direct substitute based on these parameters. The primary difference is an increased current rating (25A versus 20A), which represents an upward-compatible specification change. All mechanical, electrical interface, and compliance characteristics remain identical.

Parameter Comparison

Engineering Selection Recommendations

The ET225P12-Z is the qualified substitute for the obsolete ET220P12-Z. Both components maintain identical mechanical interfaces, electrical circuit topology, and regulatory compliance certifications. The ET225P12-Z carries Active product status, ensuring continued availability and supply chain support. The increased current rating of the substitute part (25A versus 20A) provides enhanced operational margin without introducing any compatibility concerns for applications originally specified with the 20A-rated ET220P12-Z. ROHS3 compliance is maintained across both parts, supporting environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the ET225P12-Z be used as a direct replacement for the ET220P12-Z in existing designs?

A: Yes. The ET225P12-Z is mechanically and electrically compatible with the ET220P12-Z. Panel cutout dimensions, bushing thread specifications, actuator geometry, and termination style are identical. The increased current rating represents an upward-compatible specification.

Q: What is the primary reason for substitution?

A: The ET220P12-Z is classified as obsolete. The ET225P12-Z is an active product from the same manufacturer with equivalent functionality and superior current handling capability.

Q: Are there any packaging differences between these parts?

A: The ET220P12-Z is specified with dash packaging, while the ET225P12-Z is supplied in bulk packaging. This does not affect component functionality or electrical performance.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the ET220P12-Z and ET225P12-Z are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), supporting identical regulatory and environmental requirements.

Q: What is the electrical life specification for these switches?

A: Both parts are rated for 20,000 electrical cycles, providing equivalent operational durability across the substitution.
