Substitute Part Grouping Explanation

Substitution of the MB2011SA2W31-BC is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters: Circuit configuration (SPDT), switch function (On-Momentary), current ratings (6A AC / 3A DC), and voltage ratings (125V AC / 30V DC) must be maintained or exceeded in substitute components.

Mechanical Parameters: Mounting type (through-hole, right-angle orientation), actuator type (round button), and termination style (PC pin) establish physical compatibility with existing PCB layouts and panel cutouts.

Environmental & Compliance Parameters: Operating temperature range (-30°C to 85°C), mechanical life (100,000 cycles), and RoHS3 compliance ensure functional equivalence and regulatory alignment.

The substitute part MBN15SA2W31-BC is identified as a manufacturer-recommended equivalent based on these parameter categories.

Engineering Selection Recommendations

The MB2011SA2W31-BC is obsolete and no longer in active production. The MBN15SA2W31-BC is the manufacturer-recommended substitute, maintaining NKK Switches as the source manufacturer and ensuring ROHS3 compliance for both components. The substitute part is currently in active production status with confirmed inventory availability (907 pcs), providing supply chain continuity for replacement and new assembly applications.

Both components meet identical regulatory requirements under ROHS3 and REACH standards. Selection of the active substitute part eliminates obsolescence risk while preserving electrical and mechanical compatibility with existing designs.

Frequently Asked Questions (FAQ)

Q: Can MBN15SA2W31-BC be used as a direct replacement for MB2011SA2W31-BC?

A: Yes. Both components are manufactured by NKK Switches and share the same electrical specifications (SPDT circuit, On-Momentary function, 6A AC / 3A DC ratings) and mechanical configuration (through-hole, right-angle mounting with PC pin termination). The substitute part is the manufacturer-recommended equivalent.

Q: What is the primary reason for substitution?

A: The MB2011SA2W31-BC is obsolete and no longer manufactured. The MBN15SA2W31-BC is the active production equivalent, ensuring ongoing component availability and supply chain reliability.

Q: Are there compliance differences between the two parts?

A: No. Both components are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for electronic component applications.

Q: Does packaging differ between the main part and substitute?

A: The main part is specified with standard packaging, while the substitute is supplied in bulk packaging. This does not affect electrical or mechanical compatibility; packaging selection depends on procurement and inventory management requirements.

Q: What parameters must remain consistent when selecting a substitute pushbutton switch?

A: Circuit configuration (SPDT), switch function (On-Momentary), current and voltage ratings (6A AC / 125V AC minimum; 3A DC / 30V DC minimum), mounting type (through-hole, right-angle), actuator type (round button), and termination style (PC pin) are the critical parameters for functional equivalence.
