C&K 7101K9CME Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101K9CME is a through-hole mounted 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 design support and procurement. The 7101K9CME features a locking lever actuator with epoxy sealed terminals and is suitable for applications requiring reliable switching in the specified voltage and current ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101K9CME is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-On), mounting type (through hole), termination style (PC pin), and electrical ratings (5A at 120V AC / 28V DC). Parts meeting these core requirements are classified as direct or similar substitutes based on additional mechanical and compliance attributes.

Direct Substitute: The C&K 7101K9CSE maintains identical electrical specifications and mechanical form factor, differing only in product status (active versus obsolete) and REACH compliance classification.

Similar Substitutes: E-Switch parts 100SP1T5B4M2QE and 100SP1T5B4M2RE share the same circuit configuration, mounting type, and termination style. However, these parts exhibit variations in actuator geometry, electrical life rating, and voltage specifications that must be evaluated for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The C&K 7101K9CSE is the primary substitute for the obsolete 7101K9CME. Both parts maintain identical electrical and mechanical specifications within the 7000 series. The 7101K9CSE is currently in active production status with 922 units in stock. Note that 7101K9CSE carries REACH Affected classification, whereas the original part is REACH Unaffected. Both parts maintain ROHS3 compliance and identical electrical life ratings of 100,000 cycles.

For Cross-Manufacturer Substitution: The E-Switch 100SP1T5B4M2QE provides electrical equivalence at 5A / 120V AC ratings with identical circuit configuration and through-hole mounting. This part features a standard round actuator (21.34mm length) compared to the locking lever design of the original part, and exhibits reduced electrical life of 40,000 cycles. The 100SP1T5B4M2QE is suitable for applications where actuator geometry differences are acceptable and lower cycle life requirements are met.

Not Recommended: The E-Switch 100SP1T5B4M2RE operates at significantly reduced voltage (20V AC/DC) and current (0.4VA) ratings and is not suitable for applications requiring the full 5A / 120V specifications of the 7101K9CME.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7101K9CSE be used as a direct replacement for the 7101K9CME?

A: Yes. The 7101K9CSE maintains identical electrical ratings (5A at 120V AC / 28V DC), circuit configuration (SPDT), mounting type (through hole), and electrical life (100,000 cycles). The primary difference is product status (active versus obsolete) and REACH compliance classification. Both parts are ROHS3 compliant.

Q: What are the key differences between the C&K 7101K9CME and the E-Switch 100SP1T5B4M2QE?

A: Both parts share identical electrical ratings and SPDT configuration. The primary differences are: (1) actuator type and length (locking lever 17.88mm versus standard round 21.34mm), (2) electrical life (100,000 cycles versus 40,000 cycles), and (3) manufacturer series (7000 versus 100). Panel cutout dimensions and mechanical fit must be evaluated for your specific application.

Q: Is the E-Switch 100SP1T5B4M2RE a suitable substitute?

A: No. The 100SP1T5B4M2RE operates at 0.4VA and 20V maximum, which is insufficient for applications requiring 5A at 120V AC. This part is not electrically equivalent to the 7101K9CME.

Q: What compliance certifications should I verify when selecting a substitute?

A: Verify RoHS and REACH compliance status for your target market. The 7101K9CME is ROHS3 compliant and REACH unaffected. The 7101K9CSE is ROHS compliant and REACH affected. Both E-Switch alternatives are ROHS3 compliant and REACH unaffected. Confirm MSL rating (all listed parts are MSL 1 - unlimited) for your assembly process requirements.

Q: Does actuator length affect mechanical compatibility?

A: Yes. The 7101K9CME and 7101K9CSE both feature 17.88mm locking lever actuators, while E-Switch alternatives feature 21.34mm standard round actuators. Panel cutout dimensions, operator interface design, and available panel space must accommodate the selected actuator geometry. Verify mechanical fit before design implementation.
