Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101K2ZGI are qualified based on the following critical parameters that determine functional equivalence:

• Circuit Configuration: SPDT topology required for identical switching behavior
• Electrical Ratings: 5A current capacity and 120V AC / 28V DC voltage ratings must be maintained
• Switch Function: On-On operation for consistent control logic
• Mounting Compatibility: Panel mount with 6.35mm circular cutout and 1/4-40 bushing thread
• Termination: Solder lug connection for PCB integration
• Product Status: Active production status ensures availability and supply continuity

The E-Switch 100SP1T4B1M1QEH and 100SP1T5B1M1QEH meet all critical electrical and mechanical parameters. Variations in actuator length (16.26mm and 21.34mm respectively, versus 17.88mm on the main part) and electrical life cycles (40,000 versus 100,000) do not affect functional substitution within the specified electrical and mechanical envelope.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts maintain full electrical and mechanical compatibility with the 7101K2ZGI. Selection between the two E-Switch options depends on actuator length requirements for the specific panel layout:

• 100SP1T4B1M1QEH: 16.26mm actuator length for compact panel installations
• 100SP1T5B1M1QEH: 21.34mm actuator length for standard or recessed panel applications

All three parts are active production items with ROHS3 compliance and MSL-1 moisture sensitivity rating. The C&K 7101K2ZGI offers extended electrical life (100,000 cycles) compared to the E-Switch alternatives (40,000 cycles), which may be relevant for high-cycle-count applications. Both manufacturers employ epoxy sealing or potting for terminal protection, ensuring equivalent environmental resistance.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T4B1M1QEH and 100SP1T5B1M1QEH be used interchangeably with the C&K 7101K2ZGI?

A: Yes, both E-Switch parts are direct functional substitutes. They share identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), and mechanical mounting parameters (6.35mm cutout, 1/4-40 thread, solder lug termination). The primary difference is actuator length, which must be selected based on panel depth requirements.

Q: What is the significance of the different actuator lengths?

A: Actuator length affects the physical engagement depth with the panel. The C&K 7101K2ZGI uses a 17.88mm locking lever, while the E-Switch options provide 16.26mm (100SP1T4B1M1QEH) and 21.34mm (100SP1T5B1M1QEH) standard round actuators. Panel cutout diameter and bushing thread remain constant across all three parts, ensuring mechanical fit compatibility. Verify panel thickness and actuator clearance requirements before selection.

Q: Are there compliance or certification differences between these parts?

A: All three parts are ROHS3 compliant and carry MSL-1 moisture sensitivity ratings. The C&K part is REACH Affected, while the E-Switch parts are REACH Unaffected. Both manufacturers assign EAR99 ECCN classification. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the difference in electrical life between the main part and substitutes?

A: The C&K 7101K2ZGI is rated for 100,000 electrical cycles, while both E-Switch substitutes are rated for 40,000 cycles. This difference reflects design and testing standards between manufacturers. For applications requiring extended cycle life, the C&K part is the preferred choice. For standard switching applications, the E-Switch parts provide equivalent performance within their rated cycle specification.

Q: Are the terminal sealing methods equivalent?

A: The C&K 7101K2ZGI features epoxy potting, while the E-Switch parts use epoxy sealed terminals. Both methods provide environmental protection for solder lug connections. Functional equivalence is maintained for standard panel-mount applications.
