C&K 7205TPCKE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7205TPCKE is a panel-mount toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 20V AC/DC. This component features momentary-off-momentary (Mom-Off-Mom) switching function with anti-rotation actuator and epoxy-sealed PC pin termination. The 7205TPCKE is classified as obsolete, necessitating identification of active equivalent and substitute parts for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7205TPCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (Mom-Off-Mom)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread specification (15/32-32)
• Termination style (PC Pin)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (40,000 Cycles)

Parts meeting all these criteria are classified as direct equivalents. Parts with minor variations in non-critical parameters (such as actuator type or material finish) while maintaining full electrical and mechanical compatibility are classified as similar substitutes.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7205TPCPE is the primary direct equivalent for the obsolete 7205TPCKE. Both parts are manufactured by C&K within the 7000 series and maintain identical electrical specifications, mechanical dimensions, and functional characteristics. The 7205TPCPE is currently in active production status with RoHS compliance, making it the preferred choice for new designs and production continuity.

The E-Switch 100DP4T8B13M2REH provides an alternative substitute with full electrical and mechanical compatibility. This part maintains all critical parameters including circuit configuration, voltage/current ratings, panel cutout dimensions, and bushing thread specification. Minor differences exist in actuator type (Standard Round versus Anti-Rotation) and actuator length (18.00mm versus 17.45mm), which do not affect electrical performance or panel mounting compatibility. The 100DP4T8B13M2REH is ROHS3 compliant and REACH unaffected, offering compliance flexibility for different regulatory environments.

Frequently Asked Questions (FAQ)

Q: Can the 7205TPCPE directly replace the 7205TPCKE without circuit modifications?

A: Yes. The 7205TPCPE is a direct equivalent with identical electrical ratings (0.4VA at 20V AC/DC), circuit configuration (DPDT Mom-Off-Mom), and mechanical specifications including panel cutout dimensions (11.91mm Dia) and bushing thread (15/32-32). No circuit or panel modifications are required.

Q: What is the difference between the 7205TPCPE and the 100DP4T8B13M2REH?

A: Both parts are electrically and mechanically equivalent for panel mounting applications. The primary differences are manufacturer (C&K versus E-Switch), actuator type (Anti-Rotation versus Standard Round), and actuator length (17.45mm versus 18.00mm). These differences do not affect electrical performance or standard panel mounting compatibility.

Q: Are there compliance differences between the substitute parts?

A: Yes. The 7205TPCKE is RoHS non-compliant and REACH unaffected. The 7205TPCPE is RoHS compliant and REACH affected. The 100DP4T8B13M2REH is ROHS3 compliant and REACH unaffected. Selection should consider target market regulatory requirements.

Q: Does the 0.55mm difference in actuator length between the 7205TPCPE and 100DP4T8B13M2REH affect panel mounting?

A: No. Both parts use identical panel cutout dimensions (11.91mm Dia) and bushing thread (15/32-32). The actuator length difference does not affect mechanical fit or electrical function in standard panel mount applications.

Q: What inventory status should be considered for production planning?

A: The 7205TPCPE has 840 units in stock, and the 100DP4T8B13M2REH has 2084 units in stock. The 7205TPCKE is obsolete with 1083 units remaining. For new production, the 100DP4T8B13M2REH offers higher inventory availability.
