C&K 7203MDAKE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7203MDAKE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This component features a standard round actuator with epoxy-sealed PC pin termination, designed for On-Off-On switching applications. The 7203MDAKE is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the 7203MDAKE is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (DPDT), switch function (On-Off-On), current rating (0.4VA AC/DC), and voltage rating (20V AC/DC) must remain identical.

Mechanical Parameters: Mounting type (Panel Mount, Right Angle), actuator type (Standard Round), actuator length (6.86mm), termination style (PC Pin), panel cutout dimensions (Circular - 6.35mm Dia), and bushing thread (1/4-40) must match exactly.

Environmental Parameters: Operating temperature range (-30°C ~ 85°C) and electrical life (40,000 Cycles) must be maintained.

Construction Features: Epoxy sealed terminals and brass chrome-plated actuator material must be preserved.

Substitute parts meeting all these criteria are functionally and mechanically interchangeable with the 7203MDAKE in existing applications.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7203MDAPE serves as the direct substitute for the obsolete 7203MDAKE. Both components are electrically and mechanically identical across all functional parameters. The primary distinction is product status: the 7203MDAKE is obsolete, while the 7203MDAPE is active and currently manufactured.

For new designs and ongoing production, the 7203MDAPE is the appropriate selection. This part maintains full compatibility with existing 7203MDAKE installations while offering the advantage of active product status and continued availability.

Compliance considerations differ between the two parts. The 7203MDAPE is RoHS Compliant and REACH Affected, whereas the 7203MDAKE is RoHS non-compliant and REACH Unaffected. Applications subject to RoHS or REACH regulatory requirements must use the 7203MDAPE.

Frequently Asked Questions (FAQ)

Q: Can the 7203MDAPE directly replace the 7203MDAKE in existing assemblies?

A: Yes. The 7203MDAPE is mechanically and electrically identical to the 7203MDAKE. Panel cutout dimensions, bushing thread specifications, actuator geometry, and electrical ratings are equivalent. Direct substitution is possible without circuit or mechanical redesign.

Q: What is the primary reason to transition from 7203MDAKE to 7203MDAPE?

A: The 7203MDAKE is obsolete. The 7203MDAPE is the active production equivalent from C&K, ensuring continued component availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Yes. The 7203MDAPE is RoHS Compliant and REACH Affected. The 7203MDAKE is RoHS non-compliant and REACH Unaffected. Applications requiring RoHS or REACH compliance must use the 7203MDAPE.

Q: Do the electrical specifications remain unchanged between the two parts?

A: Electrical specifications are identical. Both parts are rated for 0.4VA at 20V AC/DC with DPDT On-Off-On configuration and 40,000 cycle electrical life.

Q: Are the mechanical mounting dimensions identical?

A: Yes. Both parts feature identical panel mount specifications: 6.35mm circular cutout, 1/4-40 bushing thread, 6.86mm actuator length, and right-angle mounting orientation.
