ET01MD1CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The ET01MD1CME is a through-hole mounted toggle switch with Single Pole Double Throw (SPDT) circuit configuration manufactured by C&K. This component is classified as obsolete and is no longer in active production. The switch is rated for 7.5A at AC/DC operation with 125V AC and 28V DC voltage ratings, featuring epoxy sealed terminals and IP57 ingress protection suitable for dust and moisture-resistant applications.

Due to its obsolete status, locating replacement inventory becomes necessary for ongoing maintenance, repair, and production support of legacy equipment. Active equivalent models within the same ET series provide functional alternatives while maintaining compatibility with existing through-hole PCB designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete ET01MD1CME is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-On
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Actuator Type: Standard Round
• Actuator Length: 6.10mm
• Ingress Protection: IP57
• Operating Temperature Range: -30°C to 85°C
• Electrical Life: 60,000 Cycles
• Base Product Number: ET01MD

Allowable Parameter Variations:

• Current Rating: Substitute parts may have lower current ratings provided the application does not exceed the substitute's maximum rating
• Voltage Rating (AC): Substitute parts may have lower AC voltage ratings provided the application does not exceed the substitute's maximum rating
• Voltage Rating (DC): Must remain at 28V or higher
• Product Status: Active status preferred for ongoing availability
• RoHS Compliance: ROHS3 Compliant acceptable as upgrade from RoHS Compliant
• Packaging: May differ from original specification

The ET01MD1CSE meets all mandatory matching parameters and is classified as an active product within the same ET series, making it a direct functional substitute despite lower current and AC voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

ET01MD1CSE as Primary Substitute:

The ET01MD1CSE is the direct equivalent for the obsolete ET01MD1CME. Both components share identical mechanical and electrical interface characteristics, including through-hole mounting, PC pin termination, standard round actuator geometry, and IP57 environmental protection rating.

The ET01MD1CSE carries active product status, ensuring continued availability and supply chain reliability. The component meets ROHS3 compliance, representing an enhanced regulatory standard compared to the original RoHS Compliant designation.

Current Rating Consideration:

The ET01MD1CSE is rated for 3A (AC/DC) compared to the original 7.5A rating. Selection of this substitute is appropriate only for applications where the actual circuit current does not exceed 3A. Applications requiring the full 7.5A capacity of the original part cannot use this substitute.

Voltage Rating Consideration:

The ET01MD1CSE maintains 28V DC rating identical to the original part. The AC voltage rating is 120V compared to the original 125V. This represents a minor reduction in AC voltage margin and is acceptable for applications operating at or below 120V AC.

Compliance and Certifications:

The ET01MD1CSE provides enhanced regulatory compliance through ROHS3 certification and REACH compliance status, making it suitable for applications subject to current environmental and chemical safety regulations.

Frequently Asked Questions (FAQ)

Q: Can the ET01MD1CSE directly replace the ET01MD1CME in existing PCB designs?

A: Yes, the ET01MD1CSE is mechanically and electrically compatible with existing through-hole PCB layouts designed for the ET01MD1CME. Both components feature identical actuator length (6.10mm), PC pin termination, and mounting footprint.

Q: What is the primary difference between these two parts?

A: The ET01MD1CME is obsolete with 7.5A current rating and 125V AC voltage rating. The ET01MD1CSE is an active product with 3A current rating and 120V AC voltage rating. Both maintain identical DC voltage (28V), circuit configuration (SPDT), and environmental protection (IP57).

Q: Is the ET01MD1CSE suitable for high-current applications?

A: The ET01MD1CSE is rated for maximum 3A (AC/DC). Applications requiring currents above 3A cannot use this substitute. Original inventory of the ET01MD1CME (7.5A rated) must be sourced for such applications.

Q: Does the ET01MD1CSE meet current environmental compliance standards?

A: Yes, the ET01MD1CSE is ROHS3 Compliant and REACH Affected, meeting current environmental and chemical safety regulations. The original ET01MD1CME carries RoHS Compliant status, which is an earlier standard.

Q: What is the difference in packaging between these parts?

A: The ET01MD1CME is supplied in bulk packaging. The ET01MD1CSE is supplied in tray packaging. Both packaging formats are suitable for through-hole assembly processes.

Q: Are there any temperature or environmental differences between these parts?

A: Both parts operate across the identical temperature range of -30°C to 85°C and maintain IP57 ingress protection rating. Electrical life is 60,000 cycles for both components.

Q: What should be verified before selecting the ET01MD1CSE as a substitute?

A: Verify that the application circuit current does not exceed 3A and that the AC voltage does not exceed 120V. Confirm that the through-hole mounting footprint and PC pin termination are compatible with existing PCB designs.
