Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 1241.8451 is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (10A AC minimum)
• Voltage rating (250V AC minimum)
• Mounting interface (Panel Mount, Front with 19.10mm circular cutout)
• Actuator type (Round, Button, Flush)
• Illumination capability (LED, 24VDC)
• Ingress protection rating (IP40 minimum)
• Operating temperature range (-25°C to 85°C)
• Mechanical life (1,500,000 cycles minimum)
• Electrical life (50,000 cycles minimum)

The SCHURTER 3-145-538 qualifies as a substitute based on matching functional requirements: SPDT circuit, 10A at 250V AC rating, panel-mount configuration, and active product status with current manufacturing support.
