C&K 7108SYCKE Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7108SYCKE is a panel-mounted toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The switch features epoxy-sealed terminals, brass chrome-plated actuator, and is suitable for applications requiring momentary-on switching functionality in the -30°C to 85°C operating range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7108SYCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting interface (panel mount with 6.35mm circular cutout and 1/4-40 bushing thread)
• Actuator geometry (standard round, 10.67mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (40,000 cycles minimum)

The C&K 7108SYCPE meets all these criteria and qualifies as a direct functional substitute. The primary distinction between these parts is product status and regulatory compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The 7108SYCPE is the direct functional equivalent of the 7108SYCKE across all electrical and mechanical parameters. Selection between these parts should be based on regulatory and compliance requirements:

The 7108SYCPE is recommended for new designs and procurement due to its active product status and RoHS compliance certification. This part satisfies modern regulatory frameworks and ensures long-term supply chain availability.

The 7108SYCKE remains suitable for legacy system maintenance and repair applications where existing inventory is available and regulatory compliance requirements are not mandated. However, the obsolete status indicates discontinued manufacturing and limited future availability.

Frequently Asked Questions (FAQ)

Q: Are the 7108SYCKE and 7108SYCPE electrically interchangeable?

A: Yes. Both parts are rated for 0.4VA at 20V AC/DC with identical SPDT circuit configuration and momentary-on switch function. Electrical performance is equivalent.

Q: Can the 7108SYCPE be used as a direct replacement in existing assemblies designed for the 7108SYCKE?

A: Yes. The mechanical interface is identical: both use panel mount configuration with 6.35mm circular cutout, 1/4-40 bushing thread, and PC Pin termination. Physical installation and electrical connection are compatible.

Q: What is the significance of the RoHS compliance difference?

A: The 7108SYCPE is RoHS Compliant, meeting restrictions on hazardous substances in electrical and electronic equipment. The 7108SYCKE is RoHS Non-Compliant. For applications subject to RoHS regulations, the 7108SYCPE is the required choice.

Q: Why is the 7108SYCKE classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The 7108SYCPE represents the active production equivalent within the same series.

Q: Are there any performance differences in operating temperature range?

A: No. Both parts operate across the identical -30°C to 85°C temperature range with 40,000 cycle electrical life rating.

Q: What is the difference in REACH status between these parts?

A: The 7108SYCPE is REACH Affected, indicating it is subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. The 7108SYCKE is REACH Unaffected. For applications in regulated markets, the 7108SYCPE ensures compliance.
