ET01MF1AVQE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The ET01MF1AVQE is a toggle switch manufactured by C&K, featuring SPDT (Single Pole Double Throw) circuitry with On-On switching function. This component is designed for through-hole, right-angle vertical mounting applications requiring 3A current capacity at 120V AC or 28V DC. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ET01MF1AVQE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (SPDT required)
• Mounting type (Through Hole, Right Angle, Vertical)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C minimum)
• Actuator type (Standard Round)

Secondary Compatibility Criteria:

• Current rating must meet or exceed 3A
• Voltage ratings must support both 120V AC and 28V DC operation
• RoHS compliance status

The substitute part 34CMSP32B6M7RT from Grayhill Inc. shares the same circuit configuration (SPDT), mounting orientation (Through Hole, Right Angle, Vertical), termination style (PC Pin), and operating temperature range. However, this substitute exhibits reduced electrical performance specifications and functional differences that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 34CMSP32B6M7RT represents an active production alternative to the obsolete ET01MF1AVQE. Both components maintain RoHS compliance and identical operating temperature specifications. However, the substitute exhibits significant electrical performance reductions across current and voltage ratings, along with functional differences in switch behavior and physical dimensions.

Selection of the 34CMSP32B6M7RT requires verification that application requirements do not exceed the substitute's electrical specifications (0.4VA at 20V maximum). The reduced actuator length (3.04mm versus 6.10mm) may impact panel mounting geometry and user interface ergonomics. The absence of specified ingress protection on the substitute should be evaluated against environmental exposure requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 34CMSP32B6M7RT directly replace the ET01MF1AVQE in existing designs?

A: Direct replacement is not recommended without design review. While both components share SPDT circuit configuration, through-hole right-angle vertical mounting, and PC pin termination, the substitute's reduced current rating (0.4VA versus 3A), lower voltage ratings (20V versus 120V AC/28V DC), and shorter actuator length (3.04mm versus 6.10mm) create functional and mechanical incompatibilities.

Q: What are the key differences in switching function between these parts?

A: The ET01MF1AVQE operates as On-On, providing two stable switch positions. The 34CMSP32B6M7RT operates as On-Off-On, providing three positions with a center off state. This functional difference affects circuit behavior and application suitability.

Q: Are both components RoHS compliant?

A: Yes. The ET01MF1AVQE is RoHS Compliant, and the 34CMSP32B6M7RT is ROHS3 Compliant. Both meet current regulatory requirements for hazardous substance restrictions.

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

A: The ET01MF1AVQE features a 6.10mm actuator length, while the 34CMSP32B6M7RT features a 3.04mm actuator length. This 3.06mm difference affects panel cutout positioning, toggle reach, and user interface ergonomics. Mechanical compatibility must be verified for panel-mounted applications.

Q: Does the 34CMSP32B6M7RT provide equivalent environmental protection?

A: The ET01MF1AVQE specifies IP57 ingress protection (dust protected, waterproof). The 34CMSP32B6M7RT does not specify ingress protection rating. Applications requiring sealed or waterproof operation must evaluate this specification gap.

Q: What inventory status should influence component selection?

A: The ET01MF1AVQE is obsolete with 695 pieces in stock. The 34CMSP32B6M7RT is active production with 847 pieces in stock. For new designs or long-term support, the active production status of the substitute provides supply chain continuity advantages.
