SCHURTER 3-137-086 Equivalent & Substitute Parts

Part Overview

The SCHURTER 3-137-086 is an anti-vandal illuminated pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 5A at 125V AC. This component is designed for panel-mount front installation with LED illumination capability and quick-connect termination. The part is classified as obsolete, necessitating identification of active equivalent alternatives to maintain supply chain continuity for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-137-086 is determined by strict equivalence across the following critical parameters:

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

Mechanical Specifications: Mounting type (panel mount, front installation), actuator geometry (round button, flush), and panel cutout dimensions (22.00mm circular) must match to permit direct physical replacement without enclosure modification.

Termination Interface: Quick-connect termination at 0.110" (2.8mm) spacing must be preserved to maintain wiring harness compatibility.

Environmental & Durability Ratings: Operating temperature range (-25°C ~ 85°C), mechanical life (1,500,000 cycles), and electrical life (200,000 cycles) establish minimum performance thresholds.

Regulatory Compliance: RoHS3 compliance status must be maintained for applications subject to hazardous substance restrictions.

The substitute part must satisfy all these parameters without deviation. Product status transition from obsolete to active indicates supply availability improvement rather than functional modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: SCHURTER 3-145-726 is the manufacturer-recommended substitute for the obsolete 3-137-086. Both components are manufactured by SCHURTER Inc. and share identical electrical ratings (SPDT, 5A, 125V AC) and functional classification (pushbutton switch).

Supply Chain Status: The 3-145-726 maintains active product status with documented inventory availability (869 pcs), whereas the 3-137-086 is classified as obsolete. Selection of the active substitute ensures long-term supply continuity and reduces procurement risk.

Regulatory Compliance: Both parts maintain RoHS3 compliance status, satisfying regulatory requirements for applications subject to hazardous substance restrictions.

Application Continuity: Direct substitution is supported by electrical and functional equivalence. No circuit redesign or application revalidation is required when transitioning from the obsolete part to the active substitute, provided the mechanical and termination specifications remain compatible with the existing installation.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-726 be used as a direct replacement for the 3-137-086 in existing applications?

A: Yes. Both parts are SPDT pushbutton switches rated for 5A at 125V AC, manufactured by SCHURTER Inc. Electrical and functional specifications are equivalent.
