Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 1241.8521 is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for electrical compatibility
• Electrical Ratings: 10A at 250V AC minimum requirement
• Switch Function: On-Momentary operation
• Illumination Specification: LED green indicator at 24VDC nominal
• Mechanical Interface: Panel mount with 22.10mm circular cutout and quick-connect 0.110" termination
• Environmental Compliance: RoHS3 compliance and operating temperature range -25°C to 85°C

The SCHURTER 3-145-866 qualifies as a direct substitute based on matching SPDT circuit configuration, 10A at 250V AC electrical ratings, and pushbutton switch function. Both components are manufactured by SCHURTER Inc., ensuring design consistency and compatibility within the MSM CS product family.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3-145-866 is the recommended substitute for the obsolete SCHURTER 1241.8521. Both components share identical electrical specifications (SPDT, 10A, 250V AC) and are manufactured by the same supplier, ensuring functional compatibility in replacement applications.

The 3-145-866 carries active product status, providing assured availability and continued manufacturer support. Both components maintain RoHS3 compliance, satisfying regulatory requirements for new installations and legacy system repairs.

Selection of the 3-145-866 is appropriate for direct substitution in applications where the original 1241.8521 is no longer procurable. Verify mechanical mounting compatibility with the panel cutout dimensions and termination style before final installation.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 3-145-866 directly replace the 1241.8521 in existing equipment?

A: Yes. Both components share identical SPDT circuit configuration, 10A at 250V AC electrical ratings, and pushbutton switch function. Verify that the panel cutout dimensions and quick-connect termination style are compatible with your installation.

Q: What is the primary reason for substitution?

A: The SCHURTER 1241.8521 is obsolete. The 3-145-866 is an active product from the same manufacturer with matching electrical and functional specifications.

Q: Are there differences in illumination specifications between these parts?

A: The input parameters do not provide illumination specifications for the 3-145-866. Confirm LED color, voltage, and indicator function with the manufacturer before substitution if illumination is critical to your application.

Q: Do both parts meet the same compliance standards?

A: Both components are RoHS3 compliant. Verify REACH status and other regulatory requirements specific to your application region.

Q: What should be verified before installing the substitute part?

A: Confirm mechanical compatibility including panel cutout diameter (22.10mm circular), termination style (quick-connect 0.110"), and operating temperature range (-25°C to 85°C). Verify electrical load requirements do not exceed 10A at 250V AC.
