Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-136-761 is determined by strict equivalence across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), current rating (5A AC), and voltage rating (125V AC) must remain identical to maintain functional compatibility within the host system.

Mechanical Parameters: Mounting type (panel mount, front), actuator type (round button), panel cutout dimensions (circular 22.00mm diameter), and termination style (quick connect 0.110"/2.8mm) must match to ensure physical installation without modification.

Environmental & Compliance Parameters: Operating temperature range (-25°C ~ 85°C), ingress protection rating (IP40), and RoHS3 compliance status must be maintained or exceeded.

The substitute part SCHURTER 3-145-686 satisfies these core substitution criteria while offering the advantage of active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-686 is the direct equivalent substitute for the obsolete 3-136-761. Both components are manufactured by SCHURTER Inc. and maintain identical electrical, mechanical, and environmental specifications across all critical parameters.

Primary Selection Basis:

The 3-145-686 is classified as an active product, ensuring uninterrupted supply chain availability and manufacturer support. This status eliminates procurement risk associated with obsolete component sourcing.

Both parts maintain ROHS3 compliance and equivalent ingress protection ratings, satisfying regulatory and environmental durability requirements.

The electrical and mechanical parameter alignment—including SPDT circuit, 5A/125V AC rating, quick connect termination, and 22.00mm panel cutout—enables direct substitution without circuit redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-686 be used as a direct replacement for the 3-136-761 in existing designs?

A: Yes. The 3-145-686 maintains identical electrical ratings (SPDT, 5A, 125V AC), mechanical mounting configuration (panel mount, front), actuator type (round button), termination style (quick connect 0.110"/2.8mm), and panel cutout dimensions (22.00mm circular). No circuit or mechanical modifications are required.

Q: What is the primary advantage of switching to the 3-145-686?

A: The 3-145-686 is classified as an active product, whereas the 3-136-761 is obsolete. Active status ensures continued manufacturer availability, supply chain reliability, and technical support.
