E201SD1V3ME Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K E201SD1V3ME is a through-hole mounted toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 7.5A at 125V AC and 28V DC. This component features an On-On switch function with epoxy sealed terminals and IP57 ingress protection. The part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration (DPDT required)
• Switch function (On-On required)
• Mounting type (Through Hole required)
• Termination style (PC Pin required)
• Actuator type (Standard Round required)
• Operating temperature range (-30°C to 85°C minimum)

Secondary Compatibility Criteria:

• Current rating must meet or exceed 7.5A
• Voltage rating - AC must meet or exceed 125V
• Voltage rating - DC must meet or exceed 28V
• Ingress protection must meet or exceed IP57
• Electrical life must meet or exceed 40,000 cycles

The E201SD1V3ME is grouped with one direct equivalent from C&K and four similar alternatives from E-Switch and Grayhill Inc. All substitute parts maintain the core DPDT On-On configuration with through-hole PC pin termination and standard round actuators. Variations exist in current ratings, voltage specifications, ingress protection levels, and electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - E201SD1V3SE (C&K)

The E201SD1V3SE is the primary replacement for the obsolete E201SD1V3ME. Both parts share identical electrical ratings (7.5A at 125V AC), mechanical configuration, and operating specifications. The E201SD1V3SE maintains active product status with ROHS3 compliance. This part provides the most direct substitution path with no design modifications required.

Alternative Substitutes - E-Switch 100A Series

The E-Switch 100AWDP1T1B4M2QE and 100AWDP1T1B4VS21QE are functionally equivalent alternatives with the following considerations: current rating is reduced to 5A, voltage rating - AC is 120V, and ingress protection is upgraded to IP67. These parts are suitable for applications where the 7.5A current rating is not required. Both maintain ROHS3 compliance and active product status.

Alternative Substitutes - Grayhill Inc. 34B Series

The Grayhill 34BWDP11B4V2QT and 34BWDP11B4V3QT offer enhanced electrical life (50,000 cycles) compared to the original specification (40,000 cycles). Current rating is 5A and voltage rating - AC is 125V. Ingress protection is upgraded to IP67. The 34BWDP11B4V3QT carries ROHS3 compliance, while the 34BWDP11B4V2QT is RoHS compliant. Both are suitable for applications not requiring the full 7.5A current capacity.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch or Grayhill parts be used as direct replacements for the E201SD1V3ME?

A: The E-Switch and Grayhill parts are functionally compatible but with reduced current ratings (5A versus 7.5A). They are suitable substitutes only if the application circuit does not exceed 5A. All parts maintain identical DPDT On-On configuration, through-hole mounting, PC pin termination, and operating temperature range.

Q: What is the difference between the E201SD1V3ME and E201SD1V3SE?

A: The E201SD1V3SE is the active production equivalent of the obsolete E201SD1V3ME. Both parts have identical electrical and mechanical specifications. The primary difference is product status: E201SD1V3ME is obsolete while E201SD1V3SE is active.

Q: Why do some substitute parts have IP67 instead of IP57?

A: IP67 (dust tight, waterproof) provides enhanced ingress protection compared to IP57 (dust protected, waterproof). Parts with IP67 rating can be used in applications requiring IP57 protection without design modification.

Q: Are there any actuator length differences between substitute parts?

A: The E-Switch and C&K parts have 12.70mm actuator length, while Grayhill parts have 12.60mm actuator length. This 0.10mm difference may affect panel cutout compatibility. Verify mechanical fit in the target application.

Q: Which substitute part has the longest electrical life?

A: The Grayhill 34BWDP11B4V2QT and 34BWDP11B4V3QT both offer 50,000 electrical cycles, compared to 40,000 cycles for the original E201SD1V3ME and E201SD1V3SE.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts are RoHS compliant. The E201SD1V3SE, E-Switch 100A series, and Grayhill 34BWDP11B4V3QT carry ROHS3 compliance. The Grayhill 34BWDP11B4V2QT carries RoHS compliance. All parts are REACH unaffected or REACH affected as specified. All carry EAR99 ECCN classification.
