Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB2011SB1G01-EC is determined by the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Switch Function: Momentary (On-Mom) operation required
• Electrical Ratings: 0.4VA capacity at 28V AC/DC
• Mounting Interface: Panel mount, rear configuration with 12.50mm circular cutout compatibility
• Termination: Solder lug connection method
• Environmental Compliance: RoHS3 compliance and MSL Level 1 rating

The substitute part MBN15SB1G01-EC is classified as a large bushing miniature pushbutton switch from NKK Switches. This part maintains compatibility with the core electrical and mechanical requirements of the original component while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB1G01-EC is obsolete and no longer in active production. The MBN15SB1G01-EC is the manufacturer-recommended substitute and carries active product status, ensuring continued availability and support from NKK Switches.

Selection of the substitute part is appropriate for applications requiring:

• Replacement of failed or end-of-life MB2011SB1G01-EC components
• New designs where legacy compatibility is required
• Systems operating within the specified 28V AC/DC and 0.4VA electrical envelope

Both parts are manufactured by NKK Switches and are available in bulk packaging. Inventory levels for both components are currently adequate for procurement.

Frequently Asked Questions (FAQ)

Q: Can the MBN15SB1G01-EC directly replace the MB2011SB1G01-EC in existing applications?

A: The MBN15SB1G01-EC is the manufacturer-recommended substitute. Both components are produced by NKK Switches and share compatible electrical ratings (0.4VA at 28V AC/DC) and termination methods (solder lug). Mechanical fit and panel cutout dimensions should be verified for your specific installation.

Q: What is the difference between "Standard" and "Large Bushing Miniature" designations?

A: These designations reflect product line classifications within NKK Switches' pushbutton switch portfolio. The MB2011SB1G01-EC belongs to the MB2000 series standard line, while the MBN15SB1G01-EC is classified as a large bushing miniature variant. Both maintain the required electrical and mechanical specifications for substitution.

Q: Is the MBN15SB1G01-EC RoHS3 compliant?

A: RoHS3 compliance status for the MBN15SB1G01-EC is not specified in the provided technical data. Verification with NKK Switches is recommended if RoHS3 certification is a requirement for your application.

Q: What is the mechanical life difference between these parts?

A: The MB2011SB1G01-EC specifies 100,000 mechanical cycles and 50,000 electrical cycles. Corresponding cycle ratings for the MBN15SB1G01-EC are not provided in the available technical documentation.

Q: Are both parts available in the same packaging format?

A: Both the MB2011SB1G01-EC and MBN15SB1G01-EC are supplied in bulk packaging. Current inventory levels are 963 pieces and 711 pieces respectively.
