Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7108K2CWCKE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom momentary operation)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting interface (Panel mount with 1/4-40 bushing thread and 6.35mm circular cutout)
• Actuator specifications (Locking lever, 17.88mm length)
• Termination style (PC Pin)
• Environmental sealing (IP67 rating)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles minimum)

The C&K 7108K2CWCPE qualifies as a direct substitute based on identical electrical specifications, mechanical interface dimensions, and functional characteristics. The primary distinction is product status: the 7108K2CWCPE is active production, whereas the 7108K2CWCKE is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7108K2CWCPE is the direct active-production equivalent for the obsolete 7108K2CWCKE. Both components share identical electrical ratings, mechanical interfaces, and functional specifications within the C&K 7000 series toggle switch family.

Selection between these parts is determined by availability and compliance requirements:

• The 7108K2CWCPE is recommended for new designs and ongoing production due to active manufacturing status and current availability.
• The 7108K2CWCKE remains suitable for field replacement or maintenance of existing installations where stock exists, provided supply chain constraints do not apply.
• Both parts meet RoHS compliance requirements and carry identical ECCN and HTSUS classifications, supporting equivalent regulatory and export documentation.
• MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints for either part during storage or handling.
