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

Part Overview

The C&K 7108SYCBE is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This switch features a standard round actuator with PC pin termination and epoxy sealed terminals, designed for On-Mom switching function. The part is currently active in production with 991 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design requirements allow for compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the C&K 7108SYCBE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration must be SPDT
• Current rating must be 0.4VA (AC/DC)
• Voltage rating must support minimum 20V AC and 20V DC
• Mounting type must be Panel Mount
• Termination style must be PC Pin
• Bushing thread must be 1/4-40
• Operating temperature range must encompass -30°C ~ 85°C
• RoHS3 compliance required

Secondary Mechanical Compatibility:

• Panel cutout dimensions (Circular - 6.35mm Dia) allow for minor variations in actuator diameter
• Actuator length variations within ±0.3mm are acceptable for panel mount applications
• Actuator material differences (brass with chrome or nickel plating) do not affect electrical function

The substitute parts are grouped as follows:

Direct Equivalent (Identical Electrical Ratings): TE Connectivity ALCOSWITCH 6-1825136-2 matches the 20V AC/DC rating and all primary compatibility criteria.

Compatible Substitute (Higher Voltage Rating): NKK Switches M2015SS1G03 exceeds the voltage requirement at 28V AC/DC, making it suitable for applications where the 7108SYCBE is specified, provided the higher voltage rating does not create design conflicts.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity ALCOSWITCH 6-1825136-2 is the primary equivalent substitute for the C&K 7108SYCBE. Both parts share identical electrical ratings (20V AC/DC, 0.4VA), matching mechanical specifications (panel cutout 6.35mm, 1/4-40 bushing thread), and equivalent operating temperature range. Both are ROHS3 compliant and REACH affected. The TE Connectivity part is currently active in production with higher inventory availability (1291 units). The primary design consideration is the reduced electrical life rating (6,000 cycles versus 40,000 cycles for the C&K part), which may impact applications requiring extended cycle life.

NKK Switches M2015SS1G03 is a compatible substitute with higher voltage ratings (28V AC/DC). This part meets all primary compatibility criteria and exceeds the voltage specification of the original part. The NKK part is currently obsolete, limiting its suitability for new designs or long-term supply chain planning. The panel cutout dimension is slightly larger (6.50mm versus 6.35mm), requiring verification of panel mounting compatibility. The electrical life rating is superior (50,000 cycles), and REACH status is unaffected, which may be advantageous for certain regulatory environments.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-1825136-2 be used as a direct replacement for the C&K 7108SYCBE?

A: Yes, the TE Connectivity part meets all primary electrical and mechanical compatibility criteria. Both parts are SPDT switches rated for 0.4VA at 20V AC/DC with identical panel cutout dimensions and bushing thread specifications. The primary design consideration is the lower electrical life rating (6,000 cycles versus 40,000 cycles), which should be evaluated against application requirements.

Q: What are the limitations of using the NKK Switches M2015SS1G03 as a substitute?

A: The NKK part is currently obsolete, making it unsuitable for new production designs or long-term supply chain commitments. The panel cutout dimension is 6.50mm versus 6.35mm for the original part, requiring verification that the larger diameter does not interfere with panel mounting. The higher voltage rating (28V) is compatible with the 20V specification but should not create design conflicts in the target application.

Q: Are there packaging differences between the substitute parts?

A: Yes. The C&K 7108SYCBE is supplied in Tray packaging, while the TE Connectivity 6-1825136-2 is supplied in Bulk packaging. The NKK Switches M2015SS1G03 packaging specification is not provided. Packaging differences may affect handling, storage, and integration into assembly processes.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes, all three parts are ROHS3 compliant. However, REACH status differs: both the C&K and TE Connectivity parts are REACH affected, while the NKK part is REACH unaffected. Applications subject to REACH regulations should account for this distinction.

Q: What is the impact of actuator material differences?

A: The C&K and NKK parts use brass with chrome plating, while the TE Connectivity part uses brass with nickel plating. Both plating materials provide corrosion resistance and electrical conductivity. Material selection does not affect electrical function or mechanical compatibility for panel mount applications.

Q: Can the substitute parts be used interchangeably in existing designs?

A: Electrical and mechanical interchangeability is confirmed for the TE Connectivity 6-1825136-2. The NKK Switches M2015SS1G03 requires panel cutout verification due to the larger diameter specification. Both substitutes should be evaluated against application-specific requirements including electrical life cycles, supply chain continuity, and regulatory compliance.
