Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-678 directly replace the 3-136-757 in existing applications?

A: The 3-145-678 shares identical electrical specifications (SPDT, 5A AC, 125V AC) with the 3-136-757. Compatibility depends on verification that all mechanical parameters, including mounting type, panel cutout dimensions, and termination style, match the application requirements. Consult the detailed datasheet for the 3-145-678 to confirm mechanical compatibility.

Q: Why is the 3-136-757 classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SCHURTER 3-145-678 represents the current active equivalent, ensuring access to ongoing manufacturing and supply.

Q: Are there compliance differences between the two parts?

A: Both the 3-136-757 and 3-145-678 comply with ROHS3 and REACH requirements. No compliance barriers exist for substitution.

Q: What parameters must match for substitution to be valid?

A: Critical parameters include circuit configuration (SPDT), current rating (5A AC), voltage rating (125V AC), switch function (momentary), mounting type (panel mount front), actuator type (round button), termination style (quick connect 0.110"), and panel cutout dimensions (22.00mm circular). Operating temperature range (-25°C ~ 85°C) and ingress protection (IP40) must also be verified.

Q: Is the 3-145-678 available in the same packaging as the 3-136-757?

A: The 3-136-757 is packaged in boxes. Packaging information for the 3-145-678 is not specified in the provided data. Verify packaging requirements with the supplier before procurement.
