Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7101SD9AV2KE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current and voltage ratings (0.4VA at 20V AC/DC)
• Mounting type and orientation (Through Hole, Right Angle, Vertical)
• Actuator specifications (Standard Round, 12.45mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (100,000 Cycles)

The C&K 7101SD9AV2PE qualifies as a direct substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved compliance documentation.
