Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-559 is the direct equivalent substitute for the obsolete 3-136-753 model. Both components are manufactured by SCHURTER Inc. and maintain identical electrical, mechanical, and environmental specifications across all critical parameters.

Selection Basis:

The 3-145-559 is classified as Active product status, ensuring ongoing availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

The electrical equivalence (SPDT, 5A AC, 125V) combined with identical mechanical specifications (panel mount, 19.00mm circular cutout, Quick Connect termination) and environmental ratings (IP40, -25°C ~ 85°C operating range) establishes direct interchangeability without circuit board modification or mechanical redesign.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-559 directly replace the 3-136-753 without PCB modification?

A: Yes. Both components share identical electrical ratings (SPDT, 5A AC, 125V), mechanical mounting specifications (panel mount, 19.00mm circular cutout), and termination style (Quick Connect - 0.110"). No circuit board redesign is required.

Q: What is the primary reason for substitution?

A: The 3-136-753 is classified as obsolete. The 3-145-559 is an active product from the same manufacturer with equivalent specifications, ensuring continued component availability.

Q: Are there differences in environmental performance between these parts?

A: Both components operate across the identical temperature range (-25°C ~ 85°C) and maintain the same ingress protection rating (IP40). Environmental performance is equivalent.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 3-136-753 and 3-145-559 are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

Q: What are the critical parameters for confirming substitution compatibility?

A: Verify equivalence across circuit configuration (SPDT), current rating (5A AC), voltage rating (125V AC), mounting type (panel mount, front), panel cutout dimensions (19.00mm circular), and termination style (Quick Connect - 0.110"). All parameters must match for direct substitution.
