C&K 7101TZBES Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101TZBES 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 satin chrome actuator and is designed for applications requiring reliable switching in the low-voltage range. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs within compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101TZBES is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Mounting type must be Panel Mount
• Panel cutout dimensions must be Circular - 11.91mm Dia
• Bushing thread must be 15/32-32
• Termination style must be Solder Lug
• Operating temperature range must encompass -30°C ~ 85°C
• RoHS3 compliance status must be maintained

The E-Switch 100SP1T8B13M1QEH meets these mechanical and circuit configuration requirements. While this substitute exhibits higher current and voltage ratings (5A at 120V AC / 28V DC versus 0.4VA at 20V), it maintains identical mechanical interfaces and circuit topology, making it suitable for applications where the 7101TZBES specifications are met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7101TZBES and E-Switch 100SP1T8B13M1QEH are active production components with ROHS3 compliance. The primary distinction lies in electrical performance ratings. The 7101TZBES is specified for 0.4VA at 20V, while the 100SP1T8B13M1QEH is rated for 5A at 120V AC and 28V DC. Selection between these parts should be based on application voltage and current requirements. The 100SP1T8B13M1QEH provides higher electrical capacity and may be selected when application conditions permit. The 7101TZBES maintains higher electrical life (100,000 cycles versus 40,000 cycles) and should be selected when cycle life is a critical design parameter.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T8B13M1QEH be used as a direct replacement for the C&K 7101TZBES?

A: The 100SP1T8B13M1QEH shares identical mechanical interfaces (panel cutout, bushing thread, termination style) and circuit configuration (SPDT, On-On). It is mechanically compatible. However, electrical rating differences must be evaluated against application requirements. The substitute part has higher voltage and current ratings, which does not preclude its use in lower-voltage applications but should be confirmed against circuit design specifications.

Q: What are the mechanical compatibility requirements?

A: Both parts feature a circular 11.91mm diameter panel cutout and 15/32-32 bushing thread, enabling identical panel mounting. Actuator length differs slightly (17.45mm versus 18.00mm), which may affect panel aesthetics but does not impact functional compatibility.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant and active production components. The C&K 7101TZBES is REACH Affected, while the E-Switch 100SP1T8B13M1QEH is REACH Unaffected. Application in REACH-restricted markets may require consideration of this distinction.

Q: What is the significance of the electrical life rating difference?

A: The C&K 7101TZBES is rated for 100,000 electrical cycles, while the E-Switch 100SP1T8B13M1QEH is rated for 40,000 cycles. Applications requiring extended cycle life should prioritize the 7101TZBES specification.

Q: How do the actuator materials compare?

A: Both parts feature brass actuators with chrome plating. The C&K 7101TZBES specifies a satin chrome finish, while the E-Switch 100SP1T8B13M1QEH features epoxy sealed terminals as a distinguishing characteristic.
