Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-137-084 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Parameters:

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

Mechanical & Physical Parameters:

• Mounting configuration: Panel Mount, Front
• Actuator design: Round, Button, Flush
• Panel cutout dimensions: Circular 30.00mm diameter
• Termination style: Quick Connect 0.110" (2.8mm)

Environmental & Operational Parameters:

• Operating temperature range: -25°C ~ 85°C
• Ingress protection: IP40
• Mechanical life: 1,500,000 cycles minimum
• Electrical life: 200,000 cycles minimum

Regulatory Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status

Substitute parts must maintain equivalence across all listed parameters. Product status transition from obsolete to active does not alter electrical or mechanical specifications and does not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-656 serves as the active equivalent for the obsolete SCHURTER 3-137-084 based on matching electrical specifications (SPDT circuit, 5A at 125V AC) and mounting configuration (panel mount, front installation). Both components are manufactured by SCHURTER Inc. and maintain compliance with RoHS3 and REACH regulatory requirements.

The transition from obsolete to active product status for the 3-145-656 provides supply chain assurance and access to current manufacturing processes. The substitute part maintains functional equivalence for SPDT pushbutton switch applications within the specified voltage and current parameters.

For applications requiring the complete original specification set, including anti-vandal construction, illumination type (LED white), and mechanical/electrical life ratings, confirmation of these parameters in the 3-145-656 datasheet is necessary prior to design implementation.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-656 directly replace the 3-137-084 in existing designs?

A: Both components share identical electrical ratings (SPDT, 5A, 125V AC) and panel-mount front configuration. Direct replacement is supported for the specified electrical and mechanical parameters. Verification of illumination type, actuator design, and termination style in the 3-145-656 datasheet is required to confirm complete specification alignment.

Q: What is the primary reason for substitution?

A: The 3-137-084 is classified as obsolete. The 3-145-656 is an active product from the same manufacturer with equivalent electrical and mechanical specifications, ensuring continued component availability.

Q: Are there compliance differences between the two parts?

A: Both components are RoHS3 compliant and REACH unaffected. No compliance barriers exist for substitution.

Q: What parameters must remain identical for substitution?

A: Circuit configuration (SPDT), current rating (5A AC), voltage rating (125V AC), mounting type (panel mount front), panel cutout dimensions (30mm circular), and termination style (quick connect 0.110") must remain identical.

Q: Is the 3-145-656 suitable for the same operating temperature range?

A: The operating temperature range for the 3-145-656 is not specified in the provided data. Confirmation against the -25°C to 85°C requirement of the 3-137-084 is necessary.

Q: What inventory status supports component selection?

A: The 3-145-656 has 1,022 pieces in stock as an active product, providing immediate availability compared to the obsolete 3-137-084 status.
