SCHURTER 3-136-764 Equivalent & Substitute Parts

Part Overview

The SCHURTER 3-136-764 is an anti-vandal panel mount pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 100mA AC at 30V DC. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The MSM series switch features a round silver button actuator with quick connect 0.110" (2.8mm) termination and IP40 ingress protection suitable for industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-764 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), current rating (100mA AC), and voltage rating (30V DC) must be identical to maintain functional compatibility within existing circuit designs.

Mechanical Parameters: Mounting type (panel mount, front), actuator type (round button), and panel cutout dimensions (circular 22.00mm diameter) must match to ensure physical installation compatibility without mechanical redesign.

Termination: Quick connect 0.110" (2.8mm) termination style must be preserved for direct connection compatibility with existing wiring harnesses.

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

The substitute part must maintain these parameters to function as a direct replacement without circuit modification or mechanical adaptation.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-677 is classified as an active product, providing supply continuity for the obsolete 3-136-764. Both components are manufactured by SCHURTER Inc. and share identical SPDT circuit configuration and 100mA AC current rating.

Selection of the 3-145-677 as a substitute is supported by:

Product Status: The 3-145-677 active status ensures ongoing availability and manufacturing support, eliminating supply chain risk associated with the obsolete 3-136-764.

Electrical Equivalence: Matching SPDT circuit and 100mA AC rating provide functional electrical compatibility for applications currently using the 3-136-764.

Manufacturer Designation: SCHURTER Inc. has identified the 3-145-677 as the manufacturer-recommended substitute, indicating engineering validation within the manufacturer's product portfolio.

Compliance: Both components maintain RoHS3 compliance, supporting regulatory requirements in target applications.

Parameters not specified in the substitute part documentation (voltage rating, anti-vandal type, mounting configuration, termination style, and environmental ratings) require verification against application requirements before final component selection.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-677 directly replace the 3-136-764 in existing applications?

A: Direct replacement is supported for the specified electrical parameters (SPDT circuit, 100mA AC rating). Mechanical compatibility and environmental performance must be verified against the specific application requirements, as certain parameters are not documented for the 3-145-677.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: SPDT circuit configuration, 100mA AC current rating, 30V DC voltage rating, panel mount front installation, round button actuator, quick connect 0.110" (2.8mm) termination, circular 22.00mm panel cutout, IP40 ingress protection, and -25°C ~ 85°C operating temperature range.

Q: Why is the 3-136-764 classified as obsolete?

A: Obsolete status indicates the component is no longer in active production. The manufacturer has designated the 3-145-677 as the recommended successor for new designs and ongoing applications.

Q: Are there packaging differences between the two parts?

A: The 3-136-764 is supplied in box packaging. Packaging information for the 3-145-677 is not specified in available documentation.

Q: What compliance certifications apply to both parts?

A: Both components maintain RoHS3 compliance. The 3-136-764 is REACH Unaffected and classified under ECCN EAR99 with HTSUS code 8536.50.9031.

Q: Should I test the 3-145-677 before full deployment?

A: Application-specific validation is necessary to confirm compatibility across all mechanical, environmental, and electrical parameters, particularly for parameters not documented in the substitute part specification.
