Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-561 is the designated manufacturer-recommended substitute for the obsolete SCHURTER 3-136-755. Both components share identical electrical specifications (SPDT, 5A, 125V AC) and mechanical interfaces (panel mount, quick connect termination, 19.00mm circular cutout).

The primary distinction is product status: the 3-136-755 is obsolete, while the 3-145-561 is active. For new designs and ongoing production, the 3-145-561 should be specified to ensure long-term component availability and supply chain continuity. Both parts maintain RoHS3 compliance and REACH unaffected status, satisfying current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-561 directly replace the 3-136-755 in existing applications?

A: Yes. Both parts are SPDT pushbutton switches rated for 5A at 125V AC with identical panel mount configurations and quick connect termination. The mechanical and electrical interfaces are equivalent.
