C&K 7101MDV3ME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101MDV3ME is a Panel Mount Toggle Switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 120V AC and 28V DC. This component features a standard round actuator with epoxy sealed PC pin termination, designed for On-On switching applications. The 7101MDV3ME is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this series remains specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MDV3ME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 6.86mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (100,000 Cycles)

The C&K 7101MDV3SE meets all these parameters and qualifies as a direct substitute. The primary distinction between these parts is product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101MDV3SE is a direct functional equivalent to the 7101MDV3ME across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

For new designs and systems requiring regulatory compliance, the 7101MDV3SE is the appropriate choice due to its Active product status and RoHS Compliant certification. This part maintains full electrical and mechanical compatibility while meeting current environmental and safety standards.

For legacy system maintenance where the original 7101MDV3ME specification must be retained, the 7101MDV3SE provides identical functional performance and physical form factor, enabling direct substitution without circuit redesign or mechanical modification.

The difference in REACH status reflects regulatory classification rather than material composition differences affecting performance. Both parts operate identically within the specified electrical and temperature parameters.

Frequently Asked Questions (FAQ)

Q: Can the 7101MDV3SE replace the 7101MDV3ME in existing assemblies?

A: Yes. The 7101MDV3SE is mechanically and electrically identical to the 7101MDV3ME. Panel cutout dimensions, bushing thread, actuator geometry, and all electrical ratings are equivalent. Direct substitution requires no circuit modification or mechanical rework.

Q: What is the significance of the product status difference?

A: The 7101MDV3ME is classified as Obsolete, indicating C&K no longer manufactures this part number. The 7101MDV3SE is Active, meaning it remains in current production. For procurement planning, the 7101MDV3SE ensures long-term availability.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or mechanical function. Both parts deliver identical performance within the specified 5A, 120V AC / 28V DC ratings and -30°C to 85°C operating range.

Q: Are the panel mounting dimensions identical?

A: Yes. Both parts feature a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread. The standard round actuator length is 6.86mm on both parts. No mechanical modification is required for substitution.

Q: What electrical parameters must remain constant for substitution?

A: The SPDT circuit configuration, On-On switch function, 5A current rating, 120V AC and 28V DC voltage ratings, and 100,000 cycle electrical life must all be maintained. The 7101MDV3SE meets all these specifications.
