Key Parameters

Substitute Part Grouping Explanation

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

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type (Panel Mount)
• Mechanical interface (6.35mm circular cutout, 1/4-40 bushing thread)
• Actuator specifications (Standard Round, 5.08mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life (40,000 cycles)

The C&K 7108MHCPE meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement applications.
