Substitute Part Grouping Explanation
Substitution of the obsolete SCHURTER 3-102-775 is determined by strict equivalence across the following critical parameters:
- Circuit Configuration: SPDT topology must be maintained for identical switching logic
- Current and Voltage Ratings: 5A AC at 125V minimum to ensure electrical compatibility
- Mounting Specification: Panel mount, front installation with 22.10mm circular cutout diameter
- Actuator and Illumination: Round button with LED illumination capability
- Termination Interface: Quick Connect 0.110" (2.8mm) connectors for direct wiring compatibility
- Environmental Compliance: ROHS3 compliance and IP40 ingress protection rating
The SCHURTER 3-145-900 qualifies as a direct substitute based on identical MSM22 series design, matching SPDT circuit configuration, equivalent current and voltage ratings, and compatible panel mount specifications with the same mechanical interface requirements.
