Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-756 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), current rating (5A AC), and voltage rating (125V AC) must remain identical to ensure functional compatibility within the host circuit.

Mechanical Parameters: Mounting type (Panel Mount, Front), switch type (Anti-Vandal), actuator type (Round, Button), and panel cutout dimensions (Circular - 22.00mm Dia) must match to ensure physical installation compatibility.

Termination Parameters: Termination style (Quick Connect - 0.110" / 2.8mm) must be identical for connector compatibility.

Environmental & Compliance Parameters: Operating temperature range (-25°C to 85°C), ingress protection rating (IP40), and RoHS3 compliance status must be maintained.

The substitute part identified below meets all these criteria while offering active product status and current manufacturing availability.

Parameter Comparison
