C&K 7101K2CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101K2CME is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new design implementations. The 7101K2CME features a locking lever actuator with epoxy-sealed PC pin termination, suitable for applications requiring reliable switching in industrial and commercial environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101K2CME is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Panel Mount)
• Panel cutout dimensions (Circular - 6.35mm Dia)
• Bushing thread (1/4-40)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)

Substitute parts are categorized as follows:

Direct Manufacturer Equivalent: Parts from C&K that maintain identical electrical and mechanical specifications while offering active product status.

Similar Cross-Manufacturer Substitute: Parts from alternative manufacturers (E-Switch) that meet all critical electrical and mechanical parameters but may have minor variations in actuator design or electrical life ratings.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): The C&K 7101K2CSE is the primary substitute for the obsolete 7101K2CME. Both parts maintain identical electrical ratings, mechanical dimensions, and actuator specifications. The 7101K2CSE carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The difference in REACH status (7101K2CSE is REACH Affected versus 7101K2CME REACH Unaffected) requires evaluation based on end-use application requirements.

For Cross-Manufacturer Substitution: The E-Switch 100SP1T5B5M2QEH meets all critical electrical and mechanical parameters. Notable differences include a standard round actuator (versus locking lever) with increased length (21.34mm versus 17.88mm) and reduced electrical life rating (40,000 cycles versus 100,000 cycles). This substitute is suitable for applications where actuator style flexibility exists and lower cycle life requirements are acceptable. ROHS3 compliance and REACH Unaffected status align with the original part.

Frequently Asked Questions (FAQ)

Q: Can the 7101K2CSE directly replace the 7101K2CME without panel modifications?

A: Yes. Both parts share identical panel cutout dimensions (Circular - 6.35mm Dia) and bushing thread specifications (1/4-40), enabling direct mechanical substitution without panel rework.

Q: What is the significance of the actuator length difference between the 7101K2CME and 100SP1T5B5M2QEH?

A: The 7101K2CME features a 17.88mm locking lever actuator, while the E-Switch substitute has a 21.34mm standard round actuator. This difference affects panel clearance and operator interface feel. Verify available panel space and user interaction requirements before selecting the cross-manufacturer substitute.

Q: Does the reduced electrical life of the 100SP1T5B5M2QEH (40,000 cycles) impact suitability?

A: The 100SP1T5B5M2QEH is rated for 40,000 electrical cycles compared to 100,000 cycles for the original part. Application duty cycle must be evaluated to determine if this rating is sufficient for the intended use case.

Q: Are there compliance differences between the substitute parts?

A: The 7101K2CSE carries REACH Affected status, while both the original 7101K2CME and E-Switch 100SP1T5B5M2QEH are REACH Unaffected. All three parts are RoHS compliant. Regulatory requirements for the end application determine which substitute is appropriate.

Q: What is the packaging difference for the 100SP1T5B5M2QEH?

A: The E-Switch 100SP1T5B5M2QEH is supplied in bulk packaging, whereas the C&K parts use standard packaging. Verify packaging requirements for procurement and inventory management.
