Key Parameters

Substitute Part Grouping Explanation

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

• 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-DG is identified as a compatible alternative based on manufacturer designation and functional equivalence within the NKK Switches product portfolio.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB1W01-DG is classified as obsolete. The substitute part MBN15SB1W01-DG is currently active and available in higher inventory quantities (1114 pieces versus 656 pieces). Both components are manufactured by NKK Switches, ensuring design continuity and manufacturing consistency.

Selection between the main part and substitute should be based on:

• Availability requirements and project timeline
• Inventory depletion of the obsolete MB2011SB1W01-DG
• Confirmation that electrical and mechanical specifications of MBN15SB1W01-DG meet circuit requirements

Complete electrical and mechanical parameter verification of the substitute part is necessary before final design implementation.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SB1W01-DG being phased out? A: The MB2011SB1W01-DG is classified as obsolete. NKK Switches has designated MBN15SB1W01-DG as the active replacement within their product portfolio.

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

Q: Is the substitute part pin-compatible? A: Both components feature solder lug termination and are manufactured by NKK Switches. Physical compatibility with the 12.50mm circular panel cutout must be confirmed for the substitute part.
