Frequently Asked Questions (FAQ)

Q: Can the MBN15SB1W01-CB directly replace the MB2011SB1W01-CB in existing applications?

A: Yes. Both components share identical circuit configuration (SPDT), current ratings (6A AC / 3A DC), voltage ratings (125V AC / 30V DC), mounting type (Panel Mount, Rear), termination style (Solder Lug), and panel cutout diameter (12.50mm). Direct substitution is supported without circuit or mechanical redesign.

Q: What is the primary reason for seeking a substitute for the MB2011SB1W01-CB?

A: The MB2011SB1W01-CB is classified as obsolete. The MBN15SB1W01-CB maintains active product status, ensuring continued availability, manufacturer support, and compliance with current supply chain requirements.

Q: Are there compliance differences between the two parts?

A: Both components are ROHS3 compliant and REACH unaffected. Compliance certifications are equivalent.

Q: What packaging options are available for the substitute part?

A: The MBN15SB1W01-CB is supplied in bulk packaging, compared to the original part's standard packaging designation.

Q: Are the electrical life and mechanical life specifications identical?

A: The provided specifications for the substitute part do not include detailed electrical and mechanical life data. Verification of these parameters against the original part's 25,000 cycle electrical life and 100,000 cycle mechanical life should be confirmed through the manufacturer's current technical documentation.
