Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-738 is determined by electrical and mechanical parameter alignment within the pushbutton switch category. The critical parameters governing substitution eligibility are:

Electrical Parameters:

• Circuit configuration: SPDT
• Current rating: 5A (AC)
• Voltage rating: 125V AC

Mechanical Parameters:

• 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 - 16.00mm Dia

Environmental & Compliance Parameters:

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

Substitute parts must satisfy all electrical parameters and maintain mechanical compatibility with the original panel cutout and termination specifications. Product status transition from obsolete to active is a primary consideration for component selection.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-366 is the manufacturer-recommended substitute for the obsolete 3-136-738. Both components are manufactured by SCHURTER Inc. and share identical electrical ratings (5A, 125V AC, SPDT) and mechanical specifications (panel mount, anti-vandal, round button actuator, quick connect termination).

The primary distinction is product status: the 3-136-738 is obsolete, while the 3-145-366 is active. Selection of the active part ensures long-term component availability and supply chain continuity. Both parts maintain compatibility with existing panel cutout dimensions (16.00mm circular) and termination interfaces.

For applications requiring the 3-136-738, direct substitution with the 3-145-366 is supported by SCHURTER Inc. as the manufacturer-recommended equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-366 directly replace the 3-136-738 in existing designs?

A: Yes. Both components share identical electrical ratings (5A, 125V AC, SPDT circuit), mechanical mounting specifications (panel mount, front), and termination style (quick connect 0.110" / 2.8mm). Panel cutout dimensions are compatible at 16.00mm circular diameter.

Q: What is the primary reason for substitution?

A: The 3-136-738 is classified as obsolete. The 3-145-366 is the active equivalent, ensuring ongoing availability for production and service applications.
