Equivalent & Substitute Parts for C&K 7101SYCBI Toggle Switch

Part Overview

The C&K 7101SYCBI is an active-status toggle switch featuring Single Pole Double Throw (SPDT) circuitry with a 0.4VA current rating at 20V AC/DC. This panel-mount component utilizes PC pin termination and a circular 6.35mm diameter cutout, designed for applications requiring reliable switching in the -30°C to 85°C operating range. The 7101SYCBI is RoHS non-compliant and REACH-affected, making substitute identification critical for applications with regulatory compliance requirements or inventory constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SYCBI is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC/DC
• Mounting type: Panel Mount
• Termination style: PC Pin
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Operating temperature range: -30°C ~ 85°C
• Actuator material: Brass, Chrome Plated

The E-Switch 100SP1T1B1M2REH meets all mandatory matching parameters and qualifies as a direct substitute. Both components share identical electrical specifications, mechanical interface dimensions, and environmental operating conditions. Differences in electrical life cycles (100,000 vs. 40,000) and compliance certifications do not disqualify substitution but represent design variations within the same functional category.

Engineering Selection Recommendations

The E-Switch 100SP1T1B1M2REH provides functional equivalence to the C&K 7101SYCBI across all electrical and mechanical interface parameters. Selection between these components should be based on regulatory and compliance requirements:

For RoHS3 and REACH compliance-required applications: The E-Switch 100SP1T1B1M2REH is the appropriate selection, as it carries ROHS3 compliance certification and REACH unaffected status.

For applications without compliance constraints: Either component is electrically and mechanically interchangeable. The C&K 7101SYCBI offers extended electrical life (100,000 cycles vs. 40,000 cycles), which may be relevant for high-cycle-count applications.

For inventory and supply chain considerations: Both components are active-status products with current stock availability. Selection may be driven by lead time, cost, or existing supply agreements.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M2REH be used as a direct replacement for the C&K 7101SYCBI in existing designs?

A: Yes. Both components share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPDT On-On), mechanical interface dimensions (6.35mm circular cutout, 1/4-40 bushing thread), and operating temperature range (-30°C to 85°C). Panel-mount installation and PC pin termination are identical.

Q: What is the significance of the difference in electrical life ratings?

A: The C&K 7101SYCBI is rated for 100,000 electrical cycles, while the E-Switch 100SP1T1B1M2REH is rated for 40,000 cycles. This difference reflects design variations but does not affect functional equivalence. Applications requiring cycle counts exceeding 40,000 should specify the C&K component.

Q: Why does the C&K 7101SYCBI have RoHS non-compliance status?

A: RoHS compliance status is determined by material composition and manufacturing processes. The C&K 7101SYCBI is classified as RoHS non-compliant, while the E-Switch 100SP1T1B1M2REH carries ROHS3 compliance. Applications subject to RoHS directives must use the E-Switch component.

Q: Are there any mechanical differences between these components?

A: Actuator length differs slightly (C&K: 10.67mm vs. E-Switch: 10.41mm). Both components use brass, chrome-plated actuators and share identical panel cutout and bushing specifications. This minor dimensional variation does not affect panel-mount installation or functional operation.

Q: What is the REACH status difference, and does it matter for component selection?

A: The C&K 7101SYCBI is REACH-affected, while the E-Switch 100SP1T1B1M2REH is REACH unaffected. Applications subject to REACH regulations or requiring REACH unaffected components must use the E-Switch part number.
