Substitute Part Grouping Explanation

Substitution eligibility for the 7108MD9AV2LE is determined by strict equivalence across the following critical 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, 6.86mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 Cycles)
• Base product number (7108MD)

The 7108MD9AV2RE qualifies as a direct substitute based on complete alignment with all specified electrical and mechanical parameters. The primary distinction is product status: the substitute part is active and currently in production, whereas the original part is obsolete.
