Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 3-102-629 is determined by the following critical parameters:

• Circuit configuration (SPDT requirement)
• Current and voltage ratings (10A AC, 250V AC minimum)
• Illumination specifications (LED, yellow color, 24VDC nominal)
• Mounting interface (panel mount, front installation, 16.10mm circular cutout)
• Termination style (Quick Connect - 0.110" / 2.8mm)
• Ingress protection rating (IP40 minimum)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The SCHURTER 3-145-376 qualifies as a substitute based on manufacturer recommendation and functional equivalence within the MSM product family. Both components are manufactured by SCHURTER Inc. and share core electrical and mechanical compatibility parameters.
