Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-768 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Current rating: 100mA AC
• Voltage rating: 30V DC minimum
• Switch function: On-Mom (momentary operation)

Mechanical Equivalence Criteria:

• Mounting type: Panel Mount, Front
• Anti-vandal construction requirement
• Actuator type: Round, Button
• Panel cutout: Circular 22.00mm diameter
• Termination: Quick Connect 0.110" (2.8mm)

Environmental & Compliance Criteria:

• Operating temperature range: -25°C ~ 85°C
• Ingress protection: IP40 minimum
• RoHS3 compliance
• REACH unaffected status

Substitute parts must satisfy all criteria within these three categories to ensure direct functional replacement without circuit redesign or mechanical modification.
