Engineering Selection Recommendations

The MBN15SB3G03 is the designated substitute for the obsolete MB2011SB3G03. Both components are manufactured by NKK Switches and maintain identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: the MB2011SB3G03 is obsolete, while the MBN15SB3G03 is active and currently available for procurement.

Both parts maintain ROHS3 compliance and are suitable for applications requiring SPDT momentary pushbutton switches rated for 28V AC/DC operation with IP67 environmental protection. The active status of MBN15SB3G03 ensures continued availability and supply chain reliability for new designs and component replacement applications.

Frequently Asked Questions (FAQ)

Q: Can MBN15SB3G03 directly replace MB2011SB3G03 in existing applications?

A: Yes. Both components share identical electrical ratings (0.4VA at 28V AC/DC), circuit configuration (SPDT), switch function (momentary), mounting interface (panel mount rear with PC pin termination), and environmental specifications (IP67). Physical form factor compatibility is confirmed through matching 12.50mm circular panel cutout dimensions.

Q: What is the primary reason for substitution?

A: The MB2011SB3G03 is classified as obsolete. The MBN15SB3G03 is the active equivalent part from the same manufacturer, ensuring continued component availability and supply chain continuity.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and maintain equivalent regulatory status. No compliance barriers exist for substitution.

Q: What are the critical parameters that define substitution eligibility?

A: Substitution is based on matching circuit configuration (SPDT), electrical ratings (0.4VA at 28V AC/DC), switch function (momentary operation), mounting type (panel mount rear), termination style (PC pin), panel cutout dimensions (12.50mm circular), ingress protection rating (IP67), and operational life specifications (50,000 cycles minimum).

Q: Are packaging considerations relevant for this substitution?

A: Both parts are supplied in bulk packaging. No packaging-related compatibility issues exist for direct component substitution.
