Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-737 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 - 16.00mm Dia

Environmental & Compliance Criteria:

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

Substitute parts must satisfy all electrical, mechanical, and environmental parameters without deviation to ensure direct interchangeability in existing circuit designs and mechanical assemblies.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-365 is the manufacturer-recommended substitute for the obsolete 3-136-737. Both components are manufactured by SCHURTER Inc. and maintain electrical and mechanical equivalence across all specified parameters.

Selection Basis:
