Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-772 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Current rating: 5A (AC)
• Voltage rating: 125V AC
• Switch function: On-Momentary operation

Mechanical Equivalence Criteria:

• Mounting configuration: Panel Mount, Front
• Switch type: Anti-Vandal
• Actuator type: Round, Button
• Termination style: Quick Connect - 0.110" (2.8mm)
• Panel cutout dimensions: Circular - 30.00mm Dia

Environmental & Compliance Criteria:

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

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation. Product status transition from obsolete to active is a primary consideration for long-term component availability.
