Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 3-137-090 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Circuit configuration: SPDT
• Current rating: 5A (AC)
• Voltage rating: 125V AC
• Switch function: On-Mom (momentary)
• Illumination type and voltage: LED, Yellow, 2.4 VDC

Mechanical Parameters:

• Mounting type: Panel Mount, Front
• Actuator type: Round, Button, Flush
• Panel cutout dimensions: Circular - 22.00mm Dia
• Termination style: Quick Connect - 0.110" (2.8mm)

Environmental & Compliance Parameters:

• Ingress protection: IP40
• Operating temperature range: -25°C ~ 85°C
• RoHS compliance: ROHS3 Compliant

A substitute part must maintain equivalence across all these parameters to ensure direct compatibility without modification to the host system's electrical design, mechanical assembly, or panel interface.

Engineering Selection Recommendations

The SCHURTER 3-145-723 is identified as the manufacturer-recommended substitute for the obsolete 3-137-090. Both components are manufactured by SCHURTER Inc. and share the core electrical specifications: SPDT circuit configuration, 5A AC current rating, and 125V AC voltage rating.

The transition from the obsolete 3-137-090 to the active 3-145-723 is supported by the manufacturer's direct recommendation. The active product status of the 3-145-723 ensures ongoing availability and manufacturing support, addressing the supply discontinuation of the original part.

Selection of the 3-145-723 as a substitute is based on:

• Manufacturer recommendation for direct replacement
• Matching electrical ratings and circuit configuration
• Active product status ensuring continued supply chain availability
• Compliance with current regulatory standards

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-723 be used as a direct replacement for the 3-137-090?

A: The SCHURTER 3-145-723 is the manufacturer-recommended substitute. Both parts share identical electrical specifications (SPDT, 5A AC, 125V AC). Detailed mechanical and environmental parameter confirmation is required before installation to ensure compatibility with the specific panel cutout and termination requirements of the original application.

Q: Why is the 3-137-090 classified as obsolete?

A: The 3-137-090 has been discontinued by SCHURTER Inc. and is no longer in active production. The 3-145-723 represents the current active equivalent in the manufacturer's product line.

Q: What parameters must match for a substitute pushbutton switch to be compatible?

A: Critical matching parameters include circuit configuration (SPDT), current rating (5A AC), voltage rating (125V AC), switch function (On-Mom), mounting type (Panel Mount, Front), actuator type (Round, Button, Flush), panel cutout dimensions (Circular - 22.00mm Dia), termination style (Quick Connect - 0.110"), and ingress protection rating (IP40).

Q: Are there any compliance differences between the two parts?

A: The 3-137-090 is confirmed ROHS3 compliant. Compliance status for the 3-145-723 should be verified with the manufacturer's current technical documentation.

Q: What is the inventory status of these parts?

A: The 3-137-090 has 829 pieces in stock as new original inventory. The 3-145-723 has 874 pieces in stock as new original inventory.
