Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-766 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: SPDT
• Current rating: 100mA (AC)
• Voltage rating: 30V DC minimum

Mechanical Equivalence Requirements:

• Mounting type: Panel Mount, Front
• Switch type: Anti-Vandal
• Actuator type: Round, Button
• Termination style: Quick Connect - 0.110" (2.8mm)
• Panel cutout dimensions: Circular - 22.00mm Dia

Environmental & Compliance Requirements:

• Operating temperature range: -25°C to 85°C
• Ingress protection: IP40 minimum
• RoHS3 compliance

The substitute part SCHURTER 3-145-681 meets these core functional and mechanical requirements, enabling direct replacement in applications where the 3-136-766 is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-681 is designated as the manufacturer-recommended substitute for the obsolete 3-136-766. The substitute part carries active product status, ensuring ongoing availability and supply chain continuity. Both components are manufactured by SCHURTER Inc., maintaining design consistency and quality standards within the same manufacturer ecosystem.

The primary advantage of transitioning to the 3-145-681 is the shift from obsolete to active product status, eliminating long-term supply risk and supporting extended system lifecycles. The substitute maintains the core electrical specification of SPDT 100mA switching functionality required for the original application.

Selection of the 3-145-681 is appropriate for new designs, system upgrades, and replacement scenarios where the 3-136-766 is no longer procurable. Compliance certifications and environmental operating parameters should be verified against specific application requirements prior to final component selection.

Frequently Asked Questions (FAQ)

Q: What makes the SCHURTER 3-145-681 a valid substitute for the 3-136-766?

A: Both components are SCHURTER-manufactured pushbutton switches with identical SPDT circuit configuration and 100mA AC current rating. The substitute is designated as the manufacturer-recommended replacement and carries active product status, ensuring availability where the original part is obsolete.

Q: Are there mechanical compatibility concerns when substituting the 3-145-681 for the 3-136-766?

A: Mechanical compatibility depends on panel cutout dimensions, mounting type, and termination style. The input data does not specify these parameters for the 3-145-681. Verification against the substitute part's detailed specifications is required before installation.

Q: What is the difference in product status between these two parts?

A: The 3-136-766 is classified as obsolete, indicating discontinued production and limited availability. The 3-145-681 is active, meaning it is currently manufactured and supported by SCHURTER Inc., providing reliable long-term supply and technical support.

Q: Can the 3-145-681 be used in applications originally designed for the 3-136-766?

A: The 3-145-681 is the manufacturer-recommended substitute, indicating functional equivalence for the core switching application. However, complete specification verification is necessary to confirm compatibility with all mechanical, electrical, and environmental requirements of the original design.

Q: What compliance certifications apply to the substitute part?

A: The input data specifies ROHS3 compliance for the original 3-136-766. Compliance status for the 3-145-681 is not provided in the available data and should be confirmed through SCHURTER technical documentation.
