Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7109SD9AV2LE is determined by strict alignment of the following electrical and mechanical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Mom)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (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 (40,000 Cycles)
• Base product number (7109SD)

The C&K 7109SD9AV2RE meets all these criteria and serves as a direct functional equivalent with identical electrical and mechanical characteristics.
