Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SB1W01-DF is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current and voltage ratings (6A/125V AC minimum; 3A/30V DC minimum)
• Mounting type (Panel Mount, Rear)
• Panel cutout dimensions (12.50mm circular)
• Termination style (Solder Lug)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The identified substitute MBN15SB1W01-DF is manufactured by NKK Switches and maintains compatibility across these core electrical and mechanical parameters, enabling direct functional replacement in applications requiring this switch specification.

Parameter Comparison

Engineering Selection Recommendations

The MBN15SB1W01-DF is identified as the manufacturer-recommended substitute for the obsolete MB2011SB1W01-DF. Selection of this alternative is supported by:

• Active product status, ensuring ongoing availability and supply chain continuity
• Manufacturer recommendation from NKK Switches, indicating validated functional equivalence
• Bulk packaging availability, suitable for production and maintenance applications
• Compliance with RoHS3 requirements (main part specification maintained in equivalent design)

Component selection should be based on confirmation that the substitute part meets all electrical, mechanical, and environmental requirements of the original application circuit.

Frequently Asked Questions (FAQ)

Q: What makes MBN15SB1W01-DF a valid substitute for MB2011SB1W01-DF?

A: Both components are manufactured by NKK Switches and are identified through the manufacturer's substitution list. The substitute maintains compatibility across the critical parameters defining this switch category: circuit configuration, current and voltage ratings, mounting type, panel cutout dimensions, and termination style.

Q: Why is the MB2011SB1W01-DF classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The MBN15SB1W01-DF, with active product status, represents the current equivalent offering from the manufacturer for this functional requirement.

Q: Are there packaging differences between these parts?

A: The main part packaging is not specified in the available data. The substitute is available in bulk packaging, which is standard for production and maintenance applications.

Q: Can I use MBN15SB1W01-DF as a direct replacement in existing designs?

A: Direct replacement is valid when the substitute part meets all electrical, mechanical, and environmental specifications required by the original application. Verification of panel cutout compatibility and termination requirements is necessary before implementation.

Q: What compliance certifications apply to these components?

A: The MB2011SB1W01-DF is ROHS3 compliant and REACH unaffected. Compliance status for the substitute part should be confirmed with the manufacturer or distributor documentation.
