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

Part Overview

The C&K 7101TPZBE is an active-status toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This panel-mount switch features an anti-rotation brass actuator with epoxy-sealed solder lug terminals and operates across -30°C to 85°C. The part is ROHS3 compliant and maintains an electrical life of 100,000 cycles. Substitute parts are identified when equivalent mechanical mounting, circuit topology, and termination compatibility exist within acceptable electrical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

The E-Switch 100SP1T8B13M1QEH qualifies as a substitute based on the following alignment criteria:

Mechanical Compatibility: Both parts share identical panel cutout dimensions (11.91mm circular) and bushing thread specification (15/32-32), enabling direct mechanical interchange in panel-mount applications without modification to mounting hardware or panel geometry.

Circuit Topology: Both parts implement SPDT circuit configuration with On-On switch function, providing equivalent electrical switching behavior for two-position control applications.

Termination Interface: Both parts utilize solder lug termination style, maintaining compatibility with existing PCB or wiring harness connections designed for the 7101TPZBE.

Environmental Operating Range: Both parts operate across -30°C to 85°C, ensuring functional equivalence across the specified temperature envelope.

Regulatory Compliance: Both parts are ROHS3 compliant and carry EAR99 ECCN classification, meeting equivalent regulatory requirements.

Substitution Limitations: The 100SP1T8B13M1QEH operates at higher electrical ratings (5A at 120V AC / 28V DC) compared to the 7101TPZBE (0.4VA at 20V). This represents an over-specification in electrical capacity. The substitute exhibits reduced electrical life (40,000 cycles versus 100,000 cycles). These differences do not prevent substitution in applications where the 7101TPZBE electrical and cycle-life specifications are not fully utilized.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7101TPZBE and E-Switch 100SP1T8B13M1QEH maintain active product status and ROHS3 compliance. Selection between these parts depends on application-specific electrical load requirements and cycle-life expectations. The 7101TPZBE is specified for 0.4VA operation at 20V with 100,000 electrical cycles. The 100SP1T8B13M1QEH provides higher electrical capacity (5A at 120V AC / 28V DC) with 40,000 electrical cycles. For applications operating within the 7101TPZBE electrical envelope and requiring the full 100,000-cycle life specification, the original part is the appropriate selection. For applications where electrical load or voltage requirements exceed the 7101TPZBE specification, or where cycle-life requirements do not exceed 40,000 cycles, the 100SP1T8B13M1QEH provides mechanical and functional equivalence with enhanced electrical capacity.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T8B13M1QEH directly replace the C&K 7101TPZBE in existing panel assemblies?

A: Yes. Both parts share identical panel cutout dimensions (11.91mm circular) and bushing thread specification (15/32-32). No modification to panel geometry or mounting hardware is required for mechanical interchange.

Q: What are the key differences between these two parts?

A: The primary differences are electrical rating and electrical life. The 7101TPZBE is rated for 0.4VA at 20V with 100,000 cycles. The 100SP1T8B13M1QEH is rated for 5A at 120V AC / 28V DC with 40,000 cycles. Both implement identical SPDT circuit topology and On-On switch function.

Q: Are both parts suitable for the same voltage and current applications?

A: No. The 7101TPZBE is specified for 0.4VA at 20V maximum. The 100SP1T8B13M1QEH supports higher electrical loads (5A at 120V AC / 28V DC). If your application operates at or below 0.4VA and 20V, either part is acceptable. If your application requires higher electrical capacity, only the 100SP1T8B13M1QEH is suitable.

Q: Does the reduced electrical life of the 100SP1T8B13M1QEH affect substitution suitability?

A: The 100SP1T8B13M1QEH provides 40,000 electrical cycles compared to the 7101TPZBE specification of 100,000 cycles. Substitution is appropriate only when application cycle-life requirements do not exceed 40,000 cycles.

Q: Are both parts RoHS compliant?

A: Yes. Both the C&K 7101TPZBE and E-Switch 100SP1T8B13M1QEH are ROHS3 compliant.

Q: What termination method do both parts use?

A: Both parts utilize solder lug termination, providing compatibility with existing PCB and wiring harness designs.
