• Mounting Type: Panel Mount, Rear configuration
• Termination Style: Solder Lug connections
• Panel Cutout Dimensions: Circular 12.50mm diameter
• Operating Temperature Range: -30°C to 85°C minimum
• RoHS Compliance: ROHS3 Compliant

The identified substitute MBN15SB1W01-BB shares the core electrical and mechanical specifications required for direct functional replacement in applications currently using the MB2011SB1W01-BB.

Parameter Comparison

Engineering Selection Recommendations

The MBN15SB1W01-BB is the designated substitute for the obsolete MB2011SB1W01-BB. Both components are manufactured by NKK Switches and maintain identical circuit topology (SPDT), switch function (On-Momentary), and mounting configuration (Panel Mount, Rear). The substitute part carries Active product status, ensuring continued availability and manufacturing support.

The primary distinction is that MBN15SB1W01-BB is classified as a Large Bushing variant within the miniature pushbutton category. This designation indicates a mechanical design variation that does not alter the electrical performance or functional compatibility for applications requiring SPDT On-Momentary switching at the specified current and voltage ratings.

Both components utilize Solder Lug termination and are suitable for direct PCB integration in legacy system replacements and new designs requiring equivalent switching performance.

Frequently Asked Questions (FAQ)

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

A: Yes. Both components share identical circuit configuration (SPDT), switch function (On-Momentary), current ratings (6A AC / 3A DC), voltage ratings (125V AC / 30V DC), mounting type (Panel Mount, Rear), and termination style (Solder Lug). The Large Bushing designation on the substitute part indicates a mechanical variant that maintains functional compatibility.

Q: What is the significance of the "Large Bushing" designation on the substitute part?

A: The Large Bushing variant refers to the mechanical construction of the switch housing around the panel cutout interface. This does not affect electrical performance or switching characteristics. Both parts accommodate the same 12.50mm circular panel cutout dimension.

Q: Why is the main part listed as Obsolete?

A: Obsolete status indicates that the MB2011SB1W01-BB is no longer in active production by NKK Switches. The MBN15SB1W01-BB maintains Active status, ensuring continued manufacturing availability and supply chain reliability for new procurements.

Q: Are there any compliance differences between the two parts?

A: The main part MB2011SB1W01-BB is confirmed ROHS3 Compliant. RoHS compliance status for the substitute part MBN15SB1W01-BB is not specified in the provided technical data. Verification of compliance requirements should be confirmed against specific application regulatory requirements.

Q: What packaging options are available?

A: The main part is supplied in standard packaging (designation not specified). The substitute part MBN15SB1W01-BB is available in Bulk packaging, suitable for high-volume procurement and manufacturing integration.
