Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101SY9V3LE is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Current rating (5A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator specifications (Standard Round, 10.67mm length)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life (100,000 cycles)
• Series compatibility (7000 series)

The C&K 7101SY9V3RE meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: the original part is obsolete while the substitute is active, and compliance certifications differ between the two variants.

Parameter Comparison

Engineering Selection Recommendations

The C&K 7101SY9V3RE is the appropriate substitute for the obsolete 7101SY9V3LE. Both components are electrically and mechanically equivalent across all functional parameters. The substitute part is currently in active production status with 737 units available in inventory, ensuring supply chain continuity.

The 7101SY9V3RE maintains ROHS3 compliance and carries RoHS certification. The REACH status differs between the two parts; the substitute is REACH Affected while the original is REACH Unaffected.
