Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2011SB1W01-EF are identified based on the following critical parameters that determine functional compatibility:

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

The substitute part MBN15SB1W01-EF is manufactured by NKK Switches and maintains compatibility within the allowed parameter envelope for this product category.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB1W01-EF is classified as obsolete, necessitating the use of active substitute components for new procurement and system continuity. The MBN15SB1W01-EF is an active product from the same manufacturer (NKK Switches), providing supply chain continuity and reducing qualification risk.

Both components are manufactured by NKK Switches, ensuring consistency in design philosophy, manufacturing standards, and quality control processes. Selection of the substitute part should be based on verification that all electrical and mechanical parameters meet or exceed the requirements of the original application circuit.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SB1W01-EF being phased out? A: The MB2011SB1W01-EF is classified as obsolete. The MBN15SB1W01-EF is the active substitute from NKK Switches for ongoing applications.

Q: What are the critical parameters for substitution compatibility? A: Circuit configuration (SPDT), current ratings (6A AC / 3A DC minimum), voltage ratings (125V AC / 30V DC minimum), switch function (On-Mom), mounting type (Panel Mount, Rear), termination style (Solder Lug), and panel cutout dimensions (12.50mm circular) must be maintained.

Q: Are there packaging differences between the main part and substitute? A: The MB2011SB1W01-EF packaging is listed as standard, while the MBN15SB1W01-EF is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: What compliance certifications apply to both parts? A: Both parts are ROHS3 compliant. The MB2011SB1W01-EF is REACH Unaffected with ECCN classification EAR99.

Q: Can the substitute part operate in the same temperature range? A: Operating temperature specifications for the MBN15SB1W01-EF are not provided in the available data. Confirm that the substitute meets the -30°C to 85°C operating range requirement before final selection.
