SCHURTER 3-102-633 Equivalent & Substitute Parts

Part Overview

The SCHURTER 3-102-633 is an MSM series mechanical metal line switch configured as a pushbutton switch with SPDT (Single Pole Double Throw) circuit topology. This anti-vandal, illuminated panel mount component features a round flush button actuator with red LED illumination at 24 VDC nominal. The part is rated for 100mA DC at 30V with ceramic actuator construction and quick connect 0.110" (2.8mm) termination.

This component is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain system functionality, ensure design continuity, and support ongoing production or maintenance requirements where original inventory becomes depleted.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3-102-633 is determined by the following critical parameters:

• Circuit configuration (SPDT requirement)
• Switch type classification (Anti-Vandal, Illuminated)
• Current and voltage ratings (100mA DC, 30V DC minimum)
• Illumination specifications (LED, Red, 24 VDC nominal)
• Mounting interface (Panel Mount, Front orientation)
• Actuator geometry (Round, Button, Flush configuration)
• Termination connector type (Quick Connect - 0.110" / 2.8mm)
• Panel cutout compatibility (Circular - 16.10mm Dia)
• Environmental ratings (IP40 minimum, -25°C to 85°C operating range)
• Regulatory compliance (ROHS3 Compliant)

The SCHURTER 3-145-379 qualifies as a manufacturer-recommended substitute based on functional equivalence within the MSM mechanical metal line switch product family.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-379 is designated as the manufacturer-recommended substitute for the obsolete 3-102-633. This recommendation is based on:

• Active product status ensuring ongoing availability and manufacturing support
• Equivalent functional classification within the SCHURTER MSM mechanical metal line switch product family
• Compliance with ROHS3 regulatory requirements
• Maintained inventory levels supporting procurement requirements

Selection of the 3-145-379 as a replacement component is appropriate for applications requiring functional continuity with the original 3-102-633 specification.

Frequently Asked Questions (FAQ)

Q: Why is the 3-102-633 being phased out? A: The 3-102-633 is classified as obsolete. The manufacturer-recommended active substitute is the 3-145-379, which maintains functional equivalence within the MSM product line.

Q: Are the electrical specifications identical between the original and substitute? A: Both components are classified as pushbutton switches within the SCHURTER MSM mechanical metal line switch family. Detailed electrical parameter alignment should be confirmed against the complete technical datasheets for both part numbers.

Q: What is the panel cutout compatibility for the 3-145-379? A: Panel cutout dimension information for the 3-145-379 is not provided in the available technical parameters. This specification must be confirmed against the manufacturer's detailed datasheet prior to mechanical integration.

Q: Are both parts RoHS compliant? A: The 3-102-633 is ROHS3 compliant. RoHS compliance status for the 3-145-379 should be confirmed against the manufacturer's current certification documentation.

Q: Can the 3-145-379 be used as a direct drop-in replacement? A: Both components are manufactured by SCHURTER Inc. within the MSM mechanical metal line switch product family. Mechanical and electrical compatibility must be verified against complete technical specifications for both part numbers before implementation.
