Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-137-087 is determined by strict equivalence across the following critical parameters:

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

Mechanical Specifications: Panel mount front installation, anti-vandal illuminated design, round flush button actuator, and 30.00mm circular panel cutout dimensions must be preserved to maintain physical fit and form factor.

Termination: Quick-connect 0.110" (2.8mm) termination style must be maintained for connector compatibility.

Environmental & Compliance: Operating temperature range (-25°C ~ 85°C), ingress protection (IP40), and RoHS3 compliance establish the baseline environmental and regulatory requirements.

The substitute part must satisfy all these parameters without deviation. Product status transition from obsolete to active indicates supply availability improvement while maintaining technical equivalence.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SCHURTER 3-145-657 is the recommended substitute for the obsolete 3-137-087. Both components are manufactured by SCHURTER Inc. and share identical electrical ratings (SPDT, 5A, 125V AC) and functional classification (pushbutton switch).

Availability Advantage: The 3-145-657 carries active product status, ensuring long-term supply chain reliability and continued manufacturer support. The 3-137-087, classified as obsolete, presents supply discontinuation risk.

Compliance Alignment: Both parts maintain RoHS3 compliance, supporting regulatory requirements for new designs and production runs.

Inventory Consideration: Current stock availability exists for both components, enabling immediate procurement decisions. The 3-145-657 provides forward compatibility for future production cycles.

Frequently Asked Questions (FAQ)

Q: Can the 3-145-657 directly replace the 3-137-087 in existing applications?

A: Yes. Both components share identical electrical specifications (SPDT circuit, 5A AC, 125V AC) and are manufactured by SCHURTER Inc. The 3-145-657 is the active equivalent designed to replace the obsolete 3-137-087.

Q: What is the primary reason for substitution?

A: The 3-137-087 is classified as obsolete. The 3-145-657 provides equivalent functionality with active product status, ensuring continued availability and manufacturer support.

Q: Are the mechanical dimensions identical?

A: The provided specifications confirm both components are pushbutton switches with panel-mount front installation. Detailed mechanical dimension data for the 3-145-657 should be verified against the 30.00mm circular panel cutout requirement of the 3-137-087 during final integration.

Q: Do both parts meet the same compliance standards?

A: The 3-137-087 is confirmed ROHS3 compliant. Compliance documentation for the 3-145-657 should be obtained from SCHURTER Inc. to confirm equivalent regulatory status.
