Substitute Part Grouping Explanation

Substitution of the CD08RM0SK is based on electrical and mechanical parameter equivalence within the C&K CD series rotary DIP switch family. The substitute part CD08RM0SB maintains identical specifications across all critical parameters: 8-position octal configuration, 0.4VA current rating, 20VAC/DC voltage rating, rotary tool actuator, surface mount termination, copper alloy gold-plated contacts, and identical mechanical dimensions and life ratings.

The primary distinction between these parts is product status and compliance certification. The CD08RM0SK is obsolete, while CD08RM0SB is active production. Additionally, CD08RM0SB carries RoHS3 compliance, whereas CD08RM0SK is RoHS non-compliant.
