Toggle Switch SPDT 7105SCWCBE Equivalent & Substitute Parts

Part Overview

The C&K 7105SCWCBE is an active production toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features a Mom-Off-Mom function with PC pin termination and IP67 ingress protection. The part is ROHS3 compliant and maintains an operating temperature range of -30°C to 85°C. Finding equivalent substitute parts is necessary when managing supply chain continuity, inventory optimization, or when the primary manufacturer part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105SCWCBE is determined by strict alignment of the following critical parameters:

Circuit configuration must be SPDT to maintain identical switching topology. Switch function must be Mom-Off-Mom to preserve operational behavior. Current and voltage ratings must match or exceed 0.4VA at 20V AC/DC to ensure safe operation within the same electrical envelope. Mounting type must be Panel Mount with identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread (1/4-40) to ensure mechanical compatibility without redesign. Termination style must be PC Pin for direct PCB integration. Operating temperature range must encompass -30°C to 85°C. RoHS3 compliance is required for regulatory alignment.

The substitute part 3-1825137-6 (TE Connectivity ALCOSWITCH Switches, Gemini A series) meets all mandatory substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 7105SCWCBE and 3-1825137-6 are active production parts with ROHS3 compliance and REACH affected status. Selection between these parts should be based on application-specific requirements not covered by the mandatory substitution parameters. The 7105SCWCBE offers higher electrical life (40,000 cycles) compared to the substitute part (6,000 cycles), making it preferable for high-cycle applications. The 3-1825137-6 provides equivalent electrical performance and mechanical compatibility for standard-duty applications. Both parts maintain identical voltage, current, and environmental specifications, ensuring functional interchangeability within the defined parameter set.

Frequently Asked Questions (FAQ)

Q: Can the 3-1825137-6 be used as a direct replacement for the 7105SCWCBE?

A: Yes. Both parts share identical circuit configuration (SPDT), switch function (Mom-Off-Mom), electrical ratings (0.4VA at 20V AC/DC), panel mount geometry (6.35mm circular cutout, 1/4-40 thread), termination style (PC Pin), and operating temperature range (-30°C to 85°C). Mechanical and electrical compatibility is confirmed.

Q: What are the differences between these two parts?

A: The primary differences are actuator length (10.67mm vs 10.41mm), electrical life rating (40,000 cycles vs 6,000 cycles), and actuator material plating (chrome vs nickel). These differences do not affect substitution eligibility for standard applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 7105SCWCBE and 3-1825137-6 are ROHS3 compliant and REACH affected.

Q: What is the panel cutout requirement for installation?

A: Both parts require a circular panel cutout of 6.35mm diameter with a 1/4-40 bushing thread. No mechanical redesign is necessary when substituting between these parts.

Q: Which part should be selected for high-cycle applications?

A: The 7105SCWCBE is rated for 40,000 electrical cycles, compared to 6,000 cycles for the 3-1825137-6. For applications requiring extended cycle life, the 7105SCWCBE is the appropriate selection.
