Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-770 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Current rating: 5A (AC)
• Voltage rating: 125V AC
• Switch function: On-Momentary operation

Mechanical Equivalence Criteria:

• Mounting configuration: Panel Mount, Front
• Switch type: Anti-Vandal construction
• Actuator type: Round, Button
• Termination style: Quick Connect - 0.110" (2.8mm)
• Panel cutout dimensions: Circular - 30.00mm Dia

Compliance Equivalence Criteria:

• RoHS3 Compliance
• REACH Unaffected status
• Operating temperature range: -25°C ~ 85°C

Substitute parts must satisfy all electrical, mechanical, and compliance parameters without deviation. Product status transition from obsolete to active is permissible when all functional parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-652 is the direct equivalent substitute for the obsolete 3-136-770. Both components are manufactured by SCHURTER Inc. and maintain identical electrical specifications (SPDT, 5A, 125V AC), mechanical configuration (panel mount, anti-vandal, round button actuator), and termination interface (Quick Connect 0.110" / 2.8mm).

The primary distinction is product status: the 3-136-770 is classified as obsolete, while the 3-145-652 is active. This transition ensures continued component availability and manufacturing support. Both parts maintain full compliance with ROHS3 and REACH regulatory requirements.

For applications requiring the 3-136-770, direct substitution with the 3-145-652 is supported without circuit redesign, panel modification, or connector interface changes. The active status of the 3-145-652 provides superior long-term supply chain reliability and technical support access.

Frequently Asked Questions (FAQ)

Q: Can the 3-145-652 be used as a direct replacement for the 3-136-770 in existing designs?

A: Yes. The 3-145-652 maintains identical electrical ratings (SPDT, 5A, 125V AC), mechanical mounting configuration (panel mount, front), actuator type (round button), and termination interface (Quick Connect 0.110" / 2.8mm). No circuit modifications or panel alterations are required.

Q: What is the primary reason for substitution?

A: The 3-136-770 is classified as obsolete. The 3-145-652 is the active equivalent, ensuring ongoing component availability and manufacturing support.

Q: Are there compliance differences between these parts?

A: No. Both the 3-136-770 and 3-145-652 are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.

Q: Do the panel cutout dimensions remain the same?

A: Yes. Both components require a circular 30.00mm diameter panel cutout. Existing panel designs require no modification.

Q: Is the termination interface identical?

A: Yes. Both parts use Quick Connect - 0.110" (2.8mm) termination. Existing harnesses and connectors are compatible without modification.

Q: What is the operating temperature range for the substitute part?

A: The 3-145-652 operates across the same temperature range as the original part: -25°C to 85°C.

Q: Are the mechanical and electrical life ratings provided for the substitute part?

A: The input parameters for the 3-145-652 do not include mechanical or electrical life specifications. Refer to the SCHURTER 3-145-652 datasheet for these performance metrics.
