Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105P3CWCKE is determined by strict equivalence across the following critical parameters:

Circuit configuration (SPDT), switch function (Mom-Off-Mom), current rating (0.4VA AC/DC), voltage rating (20V AC/DC), mounting type (Panel Mount), actuator type (Flat Anti-Rotation), actuator length (11.43mm), termination style (PC Pin), panel cutout dimensions (Circular 6.35mm Dia), bushing thread (1/4-40), ingress protection (IP67), and operating temperature range (-30°C to 85°C).

The C&K 7105P3CWCPE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: the 7105P3CWCPE is active, whereas the 7105P3CWCKE is obsolete.
