Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SB3W01-EC is determined by the following critical parameters:

• Circuit configuration (SPDT)
• Current and voltage ratings (6A/125V AC minimum; 3A/30V DC minimum)
• Mounting type (Panel Mount, Rear)
• Actuator type and color (Round Button, Red)
• Termination style (Solder Lug)
• Ingress protection rating (IP67 or equivalent)
• Panel cutout dimensions (Circular 12.50mm Dia)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life specifications

The substitute part MBN15SB3W01-EC is listed as a manufacturer-recommended equivalent by NKK Switches and maintains compatibility within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB3W01-EC is classified as obsolete. The manufacturer-recommended substitute MBN15SB3W01-EC carries active product status, indicating ongoing availability and support from NKK Switches. Selection of the substitute part is supported by manufacturer designation and active inventory status. The main part is ROHS3 compliant; compliance information for the substitute should be verified through the manufacturer's current technical documentation prior to final component selection for new designs or critical applications.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SB3W01-EC listed as obsolete? A: The MB2011SB3W01-EC has reached end-of-life status with NKK Switches. The manufacturer recommends MBN15SB3W01-EC as the active equivalent for ongoing applications.

Q: What electrical parameters must match for substitution? A: The substitute part must maintain SPDT circuit configuration, support minimum 6A at 125V AC and 3A at 30V DC, and retain the On-Mom switch function to ensure functional compatibility.

Q: Are the mechanical specifications identical between the main part and substitute? A: The panel mount rear configuration, solder lug termination, and circular 12.50mm panel cutout dimensions are critical for mechanical compatibility. Detailed specifications for the substitute part should be confirmed with the manufacturer.

Q: What is the significance of IP67 ingress protection? A: IP67 rating ensures dust-tight and waterproof operation. This specification must be maintained in any substitute to preserve environmental protection in the application.

Q: Can the substitute part be used in existing designs without modification? A: The manufacturer-recommended designation indicates functional and mechanical compatibility. However, complete technical specifications for MBN15SB3W01-EC should be reviewed to confirm all parameters match application requirements.
