C&K 7201SDCKE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The C&K 7201SDCKE is a panel-mounted 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 terminals and operates across a temperature range of -30°C to 85°C. The 7201SDCKE is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where this series remains specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SDCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (DPDT)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread specification (1/4-40)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (100,000 Cycles)

The C&K 7201SDCPE meets all these criteria and belongs to the same 7000 series, making it a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SDCPE is the direct substitute for the obsolete 7201SDCKE. Both components are electrically and mechanically identical across all functional parameters. The primary distinction lies in product status and regulatory compliance:

The 7201SDCPE is currently in active production status, ensuring availability for new procurements and system replacements. The 7201SDCPE carries RoHS compliance certification, whereas the 7201SDCKE does not. For applications subject to RoHS requirements or environmental regulations, the 7201SDCPE is the appropriate selection. Both parts maintain identical electrical performance, mechanical fit, and thermal operating characteristics, supporting direct substitution in existing designs.

Frequently Asked Questions (FAQ)

Q: Can the 7201SDCPE directly replace the 7201SDCKE in existing assemblies?

A: Yes. The 7201SDCPE is mechanically and electrically identical to the 7201SDCKE. Panel cutout dimensions, bushing thread specifications, actuator geometry, and all electrical ratings are equivalent, enabling direct substitution without design modification.

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

A: The 7201SDCKE is classified as obsolete, indicating it is no longer manufactured. The 7201SDCPE is in active production, ensuring reliable supply for new orders and replacements. For long-term system support, the 7201SDCPE is the recommended choice.

Q: How do RoHS and REACH compliance differences affect component selection?

A: The 7201SDCPE is RoHS compliant and REACH affected, while the 7201SDCKE is RoHS non-compliant and REACH unaffected. Applications subject to RoHS directives or operating in regulated markets require the 7201SDCPE. For applications without such regulatory requirements, both parts function identically.

Q: Are there any electrical performance differences between these parts?

A: No. Both the 7201SDCKE and 7201SDCPE maintain identical current ratings (0.4VA), voltage ratings (20V AC/DC), operating temperature range (-30°C to 85°C), and electrical life (100,000 cycles).

Q: What are the critical mechanical parameters for substitution compatibility?

A: Panel cutout diameter (6.35mm circular), bushing thread (1/4-40), actuator type (standard round), and actuator length (12.45mm) must remain constant. The 7201SDCPE matches all these specifications with the 7201SDCKE.
