C&K 7103MDAKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7103MDAKE is a toggle switch with SPDT (Single Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This panel-mount, right-angle switch features a standard round actuator and PC pin termination. The 7103MDAKE is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations where this component is specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 7103MDAKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type and orientation (Panel Mount, Right Angle)
• 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 rating (40,000 Cycles)

The C&K 7103MDAPE meets all these criteria and qualifies as a direct substitute for the obsolete 7103MDAKE.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7103MDAPE is the direct substitute for the obsolete 7103MDAKE. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications.

The 7103MDAPE offers the additional advantage of active product status with RoHS compliance, making it suitable for new designs and applications subject to environmental regulations. The REACH Affected designation on the 7103MDAPE indicates compliance with REACH regulatory requirements, which may be required depending on end-use application and regional deployment.

For applications where the 7103MDAKE is currently specified, transition to the 7103MDAPE requires no circuit redesign or mechanical modification, as all critical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the 7103MDAPE directly replace the 7103MDAKE without circuit modification?
