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

Part Overview

The C&K 7201SDAKE 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 and operates across -30°C to 85°C. The 7201SDAKE is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations where this switch type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7201SDAKE is determined by strict equivalence across the following parameters: DPDT circuit configuration, On-On switch function, 0.4VA current rating at 20V AC/DC, panel-mount right-angle orientation, circular 6.35mm panel cutout, 1/4-40 bushing thread, and PC pin termination. All identified substitutes maintain these core electrical and mechanical specifications, ensuring direct functional compatibility within the original application envelope.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7201SDAPE represents the primary direct substitute for the obsolete 7201SDAKE. Both components share identical electrical ratings, mechanical dimensions, and termination specifications within the C&K 7000 series. The 7201SDAPE is currently in active production status and achieves RoHS compliance, addressing regulatory requirements for new designs and system updates.

The TE Connectivity 2-1825138-2 (Gemini A series) provides functional equivalence across all core electrical and mechanical parameters. This substitute maintains the required DPDT configuration, 0.4VA/20V rating, panel-mount orientation, and PC pin termination. Differences in actuator length (10.41mm versus 12.45mm) and electrical life rating (6,000 cycles versus 100,000 cycles) must be evaluated against specific application requirements. The 2-1825138-2 carries active product status and ROHS3 compliance.

Selection between the C&K 7201SDAPE and TE Connectivity 2-1825138-2 depends on application-specific cycle life requirements, actuator geometry constraints, and supply chain considerations. Both substitutes maintain functional compatibility with the original 7201SDAKE specification envelope.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7201SDAPE directly replace the obsolete 7201SDAKE?

A: Yes. The 7201SDAPE maintains identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (DPDT On-On), mechanical mounting (panel mount, right angle), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and PC pin termination. Both components are from the C&K 7000 series and are functionally interchangeable.

Q: What are the key differences between the C&K 7201SDAPE and TE Connectivity 2-1825138-2?

A: Both maintain equivalent electrical specifications and mechanical mounting. The TE Connectivity part features a shorter actuator length (10.41mm versus 12.45mm) and lower electrical life rating (6,000 cycles versus 100,000 cycles). Actuator material differs: C&K uses brass with chrome plating; TE Connectivity uses brass with nickel plating. These differences require evaluation against specific panel geometry and cycle life requirements.

Q: Are there packaging differences between substitute options?

A: The C&K 7201SDAPE is packaged in standard format. The TE Connectivity 2-1825138-2 is supplied in bulk packaging. Procurement and inventory management processes should account for these packaging variations.

Q: Do all substitute parts meet current regulatory requirements?

A: The C&K 7201SDAPE and TE Connectivity 2-1825138-2 both achieve RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively) and are REACH Affected. The original 7201SDAKE is RoHS non-compliant and REACH Unaffected. New designs should prioritize compliant substitutes.

Q: What electrical life cycle considerations apply to the TE Connectivity substitute?

A: The TE Connectivity 2-1825138-2 is rated for 6,000 electrical cycles compared to 100,000 cycles for both C&K options. Applications requiring frequent switching operations should verify that the lower cycle rating meets operational requirements.
